[0054] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0055] It should be noted that the terms "including" and "having" and any variations thereof in the embodiments of the present application and the accompanying drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0056] It is understood that the terms "first", "second", etc. used in this application can be used to describe various elements in this article, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, without departing from the scope of this application, the first Bluetooth device can be referred to as the second Bluetooth device, and similarly, the second Bluetooth device can be referred to as the first Bluetooth device. Both the first Bluetooth device and the second Bluetooth device are Bluetooth devices, but they are not the same Bluetooth device. The term "plurality" used in this application refers to two or more. The term "and / or" used in this application refers to one of the schemes, or any combination of multiple schemes.

[0057] In some application scenarios, users often need to make Bluetooth devices in different device sets work together, such as wanting different pairs of Bluetooth headsets to share music transmitted by the same mobile phone. In related technologies, for solutions to allow different pairs of Bluetooth headsets to share audio, the first is that the terminal device transmits audio data to one pair of Bluetooth headsets, and then the pair of headsets forwards it to another pair of Bluetooth headsets to achieve audio sharing; the second is based on the broadcast mechanism in BLE (Bluetooth Low Energy) technology, where the terminal device uses BLE broadcast to transmit audio data to different pairs of Bluetooth headsets to achieve audio sharing, etc.

[0058] For the first audio sharing method mentioned above, additional hardware or customized chips may be required to realize the audio sharing function, which increases costs and has poor compatibility. For the second audio sharing method mentioned above, since audio data is transmitted through connectionless BLE broadcasting, the reliability of transmission cannot be guaranteed.

[0059] The embodiments of the present application disclose an information updating method and device, an audio sharing method and system, an electronic device, and a storage medium, which can dynamically and flexibly combine Bluetooth devices of different Bluetooth device sets into the same Bluetooth device set for collaborative use, thereby meeting the use needs of users. In addition, audio sharing between N first Bluetooth devices and M second Bluetooth devices can be achieved, and the reliability of audio data transmission is improved.

[0060] Figure 1A FIG. 1 is an application scenario diagram of an information updating method and an audio sharing method in an embodiment. Figure 1A As shown, the first Bluetooth device set may include N first Bluetooth devices 120, and the second Bluetooth device set may include M second Bluetooth devices 130, where N and M are both integers greater than 1. The first Bluetooth device 120 and the second Bluetooth device 130 may include but are not limited to earphones, mobile phones, wearable devices, speaker devices, smart home devices and other devices. Furthermore, the first Bluetooth device 120 and the second Bluetooth device 130 may be TWS (True Wireless Stereo) earphones. The first Bluetooth device 120 and the second Bluetooth device 130 may be the same Bluetooth device or different Bluetooth devices.

[0061] The electronic device 110 may be a device capable of establishing a communication connection with the first Bluetooth device 120 and the second Bluetooth device 130. For example, the electronic device 110 may be an electronic device used in conjunction with the first Bluetooth device 120 and the second Bluetooth device 130. For example, the first Bluetooth device 120 and the second Bluetooth device 130 are both headphones, and the electronic device 110 may be a headphone box, etc., but is not limited thereto. The electronic device 110 may also include, but is not limited to, a mobile phone, a smart wearable device, a vehicle-mounted terminal, a tablet computer, a PC (Personal Computer), a PDA (Personal Digital Assistant), etc.

[0062] Each Bluetooth device may be provided with collection information, and the collection information may be used to indicate the Bluetooth device collection to which the Bluetooth device belongs. Optionally, the collection information may include combination identification information, and Bluetooth devices belonging to different Bluetooth device collections may correspond to different combination identification information, and the combination identification information may be used to identify the Bluetooth device collection to which the Bluetooth device belongs, and Bluetooth devices belonging to the same Bluetooth device collection may correspond to the same combination identification information, and an external device may identify multiple Bluetooth devices as a Bluetooth device collection through the combination identification information, so as to achieve the purpose of coordinated and synchronous use of Bluetooth devices belonging to the same Bluetooth device collection. For example, for the N first Bluetooth devices 120 in the first Bluetooth device collection, the same first combination identification information may be corresponded, and for the M second Bluetooth devices 130 in the second Bluetooth device collection, the same second combination identification information may be corresponded, and the first combination identification information is different from the second combination identification information, so as to ensure that the N first Bluetooth devices 120 in the first Bluetooth device collection and the M second Bluetooth devices 130 in the second Bluetooth device collection will not be confused when in use.

[0063] In the embodiment of the present application, it is possible to successfully configure N first Bluetooth devices 120 that originally belonged to the first Bluetooth device set and M second Bluetooth devices 130 that originally belonged to the second Bluetooth device set to belong to the target Bluetooth device set for collaborative use. The electronic device 110 can establish a communication connection with the N first Bluetooth devices 120 of the first Bluetooth device set, and send the target set information to the N first Bluetooth devices 120, so that the N first Bluetooth devices 120 update the first set information to the target set information. The electronic device 110 can establish a communication connection with the M second Bluetooth devices 130 of the second Bluetooth device set, and send the target set information to the M second Bluetooth devices 130, so that the M second Bluetooth devices 130 update the second set information to the target set information. The target set information is used to indicate the target Bluetooth device set, and the N first Bluetooth devices 120 and the M second Bluetooth devices 130 that have updated the target set information can be successfully added to the target Bluetooth device set, thereby realizing that the N first Bluetooth devices 120 and the M second Bluetooth devices 130 are identified as belonging to the same Bluetooth device set for collaborative use.

[0064] The above-mentioned communication connection may include but is not limited to wireless communication connection such as Bluetooth, and the Bluetooth communication connection may include but is not limited to any one of classic Bluetooth connection, BLE (Bluetooth Low Energy) connection, LE Audio Bluetooth connection, etc. Optionally, the above-mentioned communication connection may also be a physical connection method such as a contact point communication connection, and the specific communication connection method is not specifically limited in the embodiments of the present application.

[0065] Figure 1BFIG. 1 is an application scenario diagram of the information updating method and the audio sharing method in another embodiment. Figure 1B As shown, after the N first Bluetooth devices 120 update the first set information to the target set information, and the M second Bluetooth devices 130 update the second set information to the target set information, the N first Bluetooth devices 120 and the M second Bluetooth devices 130 belonging to the target Bluetooth device set can send Bluetooth broadcast signals based on the target set information. The terminal device 140 can establish Bluetooth connections with the N first Bluetooth devices 120 and the M second Bluetooth devices 130 respectively according to the scanned Bluetooth broadcast signals. For example, the N first Bluetooth devices 120 and the M second Bluetooth devices 130 can send LE Audio broadcast signals based on the target set information, and the terminal device 140 can establish LE Audio Bluetooth connections with the N first Bluetooth devices 120 and the M second Bluetooth devices 130 respectively according to the scanned LE Audio broadcast signals. After the terminal device establishes LE Audio Bluetooth connections with N first Bluetooth devices 120 and M second Bluetooth devices 130 respectively, it can establish CIS (Connected Isochronous Streams) and other audio transmission channels with the N first Bluetooth devices 120 and M second Bluetooth devices 130 respectively on the basis of the LE Audio Bluetooth connections, so as to send audio data to each first Bluetooth device 120 and each second Bluetooth device 130 respectively through the audio transmission channel, thereby realizing audio sharing between the N first Bluetooth devices 120 and the M second Bluetooth devices 130. Among them, the CIS channels established by the terminal device and the N first Bluetooth devices 120 and the M second Bluetooth devices 130 can form a CIG (Connected Isochronous Groups), and each CIS channel in the same CIG has the same timestamp, thereby ensuring that the audio data received in the CIG is synchronized.

[0066] Furthermore, each Bluetooth device under the target Bluetooth device set may be assigned a different role (eg, the left earphone plays the left channel audio, and the right earphone plays the right channel audio).

[0067] The terminal device 140 may include but is not limited to a mobile phone, a smart wearable device, a vehicle-mounted terminal, a tablet computer, a PC (Personal Computer), a PDA (Personal Digital Assistant), etc.

[0068] Figure 1C FIG. 2 is an application scenario diagram of an information updating method and an audio sharing method in another embodiment. Figure 1CAs shown, the electronic device 110 may include an earphone box 150, the first Bluetooth device set may include a first pair of earphones 160, and the second Bluetooth device set may include a second pair of earphones 170. In order to meet the user's need to use the first pair of earphones 160 and the second pair of earphones 170 in coordination, the first pair of earphones 160 and the second pair of earphones 170 may be configured to belong to the same Bluetooth device set for use through the earphone box 150. As an implementation mode, the user may respectively put the first pair of earphones 160 and the second pair of earphones 170 into the earphone box 150 (e.g., first put the first pair of earphones 160 into the earphone box 150, and then put the second pair of earphones 170 into the earphone box 150). When the first pair of earphones 160 is placed in the earphone box 150, the earphone box 150 may send the target set information to the left earphone and the right earphone of the first pair of earphones 160, respectively, and the left earphone and the right earphone of the first pair of earphones 160 may update the first set information to the target set information. When the second pair of headphones 170 is placed in the headphone box 150, the headphone box 150 can send the target set information to the left headphone and the right headphone of the second pair of headphones 170 respectively, and the left headphone and the right headphone of the second pair of headphones 170 can update the second set information to the target set information.

[0069] After the left earphone and the right earphone of the first pair of earphones 160 update the first set information to the target set information, and the left earphone and the right earphone of the second pair of earphones 170 update the second set information to the target set information, the first pair of earphones 160 and the second pair of earphones 170 are successfully added to the same Bluetooth device set. The left earphone and the right earphone of the first pair of earphones 160, and the left earphone and the right earphone of the second pair of earphones 170 can respectively establish a LEAudio Bluetooth connection with the terminal device 140 based on the target set information. The terminal device 140 can send audio data to the first pair of earphones 160 and the second pair of earphones 170 respectively, so that the first pair of earphones 160 and the second pair of earphones 170 share the audio data transmitted by the terminal device 140.

[0070] Furthermore, the terminal device 140 can send left channel audio data to the left earphone of the first pair of headphones 160 and the left earphone of the second pair of headphones 170, and send right channel audio data to the right earphone of the first pair of headphones 160 and the right earphone of the second pair of headphones 170, respectively.

[0071] It should be noted that the above-mentioned electronic device 110 can also configure Bluetooth devices that originally belonged to two or more different Bluetooth device sets to belong to the same Bluetooth device set for collaborative use, and is not limited to the above-mentioned first Bluetooth device set and second Bluetooth device set. For example, Bluetooth devices that originally belonged to 3 or 4 different Bluetooth device sets can be configured to belong to the same Bluetooth device set for collaborative use, etc., but is not limited to this.

[0072] Figure 2 FIG. 1 is a timing diagram of an information updating method in an embodiment. Figure 2 As shown, the information updating method may include the following steps:

[0073] 1. The electronic device obtains target set information.

[0074] 2. The electronic device sends the target set information to N first Bluetooth devices in the first Bluetooth device set.

[0075] 3. The N first Bluetooth devices update the first set information to the target set information.

[0076] 4. The electronic device sends the target set information to the M second Bluetooth devices in the second Bluetooth device set.

[0077] 5. The M second Bluetooth devices update the second set information to the target set information.

[0078] like Figure 3 As shown, in one embodiment, an information updating method is provided, which can be applied to the above electronic device, and the method may include the following steps:

[0079] Step 310: Acquire target set information, where the target set information is used to indicate a target Bluetooth device set.

[0080] The N first Bluetooth devices in the first Bluetooth device set and the M second Bluetooth devices in the second Bluetooth device set can be configured to belong to the same target Bluetooth device set through an electronic device. The electronic device can obtain target set information and send the target set information to the N first Bluetooth devices in the first Bluetooth device set and the M second Bluetooth devices in the second Bluetooth device set, respectively, so that the first Bluetooth device and the second Bluetooth device update the set information to successfully join the target Bluetooth device set.

[0081] In some embodiments, a user may perform a first trigger operation on an electronic device to trigger the function of the electronic device to group Bluetooth devices of different Bluetooth device sets into the same Bluetooth device set. When the electronic device detects the first trigger operation, it may respond to the first trigger operation to obtain target set information. The specific operation mode of the first trigger operation is not limited in the embodiment of the present application. For example, a specific key may be provided on the electronic device, and the specific key may be a virtual key or a physical key. The first trigger operation may be a preset operation on the specific key (such as long pressing for a period of time, clicking a specific key, double-clicking a specific key, etc.); for another example, the first trigger operation may be any one of a touch operation, a gesture operation, a voice operation, etc., and the electronic device may detect the first trigger operation through a corresponding sensor (such as detecting a preset pressing operation through a pressure sensor, detecting a preset gesture operation through a distance sensor, detecting a preset voice content through a voice sensor, etc.), but is not limited thereto.

[0082] For example, taking the electronic device as an earphone box, the first trigger operation may include long pressing the pairing button on the earphone box, double pressing the pairing button on the earphone box, setting a gesture operation on the earphone box, etc., but is not limited thereto.

[0083] Exemplarily, taking the electronic device as a mobile phone as an example, the mobile phone may provide an audio sharing button in the interface, and the first trigger operation may be clicking the audio sharing button, but is not limited thereto.

[0084] Step 320: Send the target set information to N first Bluetooth devices in the first Bluetooth device set, so that the first Bluetooth devices update the first set information to the target set information; the first set information is used to indicate the first Bluetooth device set.

[0085] Step 330: Send the target set information to M second Bluetooth devices in the second Bluetooth device set, so that the second Bluetooth devices update the second set information to the target set information; the second set information is used to indicate the second Bluetooth device set.

[0086] Each first Bluetooth device in the first Bluetooth device set may be configured with first set information, and the first set information may indicate that the first Bluetooth device belongs to the first Bluetooth device set. The electronic device may establish a communication connection with the N first Bluetooth devices in the first Bluetooth device set, and send target set information to the N first Bluetooth devices respectively. After the first Bluetooth device receives the target set information sent by the electronic device, it may update the first set information to the target set information, thereby successfully changing the first Bluetooth device from belonging to the first Bluetooth device set to belonging to the target Bluetooth device set.

[0087] Each second Bluetooth device in the second Bluetooth device set may be configured with second set information, and the second set information may indicate that the second Bluetooth device belongs to the second Bluetooth device set. The electronic device may establish a communication connection with the M second Bluetooth devices in the second Bluetooth device set, and send target set information to each of the M second Bluetooth devices. After receiving the target set information sent by the electronic device, the second Bluetooth device may update the second set information to the target set information, thereby successfully changing the second Bluetooth device from belonging to the second Bluetooth device set to belonging to the target Bluetooth device set.

[0088] The above-mentioned N and M can both be integers greater than 1, and N and M can be the same or different. For example, N and M are both 2, or N is 2 and M is 3, etc., but it is not limited thereto.

[0089] The specific connection method of the communication connection between the electronic device and the first Bluetooth device and the second Bluetooth device is not limited in the embodiments of the present application, and different communication connection methods can be selected for different electronic devices. For example, if the electronic device is a terminal device such as a mobile phone or a tablet computer, the communication connection method can be a Bluetooth communication connection, etc.; if the electronic device is a matching device corresponding to the first Bluetooth device and the second Bluetooth device, for example, the first Bluetooth device and the second Bluetooth device are both headphones, and the electronic device is a headphone box, then the communication connection method can be a contact communication connection, etc.

[0090] It should be noted that the electronic device may first establish a communication connection with the N first Bluetooth devices in the first Bluetooth device set, disconnect the communication connection with the N first Bluetooth devices after sending the target set information to the N first Bluetooth devices, and then establish a communication connection with the M second Bluetooth devices in the second Bluetooth device set; or, the electronic device may first establish a communication connection with the M second Bluetooth devices in the second Bluetooth device set, disconnect the communication connection with the M second Bluetooth devices after sending the target set information to the M second Bluetooth devices, and then establish a communication connection with the N second Bluetooth devices in the first Bluetooth device set. The electronic device may also simultaneously establish communication connections with the N first Bluetooth devices in the first Bluetooth device set and the M second Bluetooth devices in the second Bluetooth device set. The embodiment of the present application does not specifically limit the timing of the electronic device establishing a communication connection with the first Bluetooth device and the second Bluetooth device.

[0091] The embodiments of the present application do not limit the sequence of the electronic device acquiring the target set information and the electronic device establishing communication connections with the first Bluetooth device and the second Bluetooth device. For example, the electronic device may acquire the target set information before establishing communication connections with the N first Bluetooth devices and the M second Bluetooth devices, or the electronic device may first establish communication connections with the N first Bluetooth devices in the first Bluetooth device set and then acquire the target set information.

[0092] In some embodiments, the target set information may include target combination identification information, which can be used to identify the target Bluetooth device set, the first set information may include first combination identification information, which can be used to identify the first Bluetooth device set, and the second set information may include second combination identification information, which can be used to identify the second Bluetooth device set. The first combination identification information is different from the second combination identification information to ensure that the N first Bluetooth devices in the first Bluetooth device set and the M second Bluetooth devices in the second Bluetooth device set are used separately when the set information is not updated, and there will be no confusion. The target combination identification information may be different from the first combination identification information and the second combination identification information, and may also be the same as the first combination identification information or the second combination identification information.

[0093] After receiving the target combination identification information sent by the electronic device, the first Bluetooth device can update its own combination identification information from the first combination identification information to the target combination identification information. After receiving the target combination identification information sent by the electronic device, the second Bluetooth device can update its own combination identification information from the second combination identification information to the target combination identification information.

[0094] Optionally, after receiving the target combination identification information sent by the electronic device, the first Bluetooth device may determine whether the first combination identification information is the same as the target combination identification information. If they are not the same, the first combination identification information is updated to the target combination identification information. If they are the same, the first Bluetooth device may not update its own combination identification information. Similarly, after receiving the target combination identification information sent by the electronic device, the second Bluetooth device may determine whether the second combination identification information is the same as the target combination identification information. If they are not the same, the second combination identification information is updated to the target combination identification information. If they are the same, the second Bluetooth device may not update its own combination identification information.

[0095] After N first Bluetooth devices and M second Bluetooth devices update their own combination identification information to the target combination identification information, they correspond to the same target combination identification information. If an external terminal device scans the first Bluetooth device and the second Bluetooth device at the same time, since the combination identification information of the first Bluetooth device and the second Bluetooth device is the same, both are the above-mentioned target combination identification information, the first Bluetooth device and the other Bluetooth devices can be used collaboratively as a Bluetooth device set.

[0096] In some embodiments, BLE Audio (Bluetooth Low Energy Audio) technology, as a mainstream technology vigorously promoted by Bluetooth SIG in recent years, can provide people with wireless audio services with lower power consumption, lower cost, higher quality, and lower latency. CSIP (Coordinated Set Identification Profile) is provided in BLE Audio technology, which allows multiple Bluetooth devices belonging to the same Bluetooth device set to achieve the purpose of coordination and synchronization when interacting with external devices. In CSIP, for multiple Bluetooth devices belonging to the same Bluetooth device set, the same SIRK (Set Identity Resolving Key) can be used, that is, Bluetooth devices with the same SIRK are identified as the same Bluetooth device set.

[0097] In an embodiment of the present application, the target combination identification information may include a target SIRK, the first combination identification information may include a first SIRK, and the second combination identification information may include a second SIRK. After receiving the target SIRK sent by the electronic device, the first Bluetooth device may update its own SIRK from the first SIRK to the target SIRK. After receiving the target SIRK sent by the electronic device, the second Bluetooth device may update its own SIRK from the second SIRK to the target SIRK. Since the first Bluetooth device and the second Bluetooth device are both configured with the same target SIRK, the first Bluetooth device and the second Bluetooth device are successfully added to the same target Bluetooth device set. When the various Bluetooth devices under the target Bluetooth device set interact with an external terminal device, since they are configured with the same target SIRK, the external terminal device can coordinate and synchronously use the various Bluetooth devices under the target Bluetooth device set.

[0098] In some embodiments, in addition to the target combination identification information, the target set information may also include information such as a quantity parameter (Size) and / or a sequence number (Rank). The quantity parameter is used to indicate the number of Bluetooth devices included in the target Bluetooth device set. In an embodiment of the present application, the quantity parameter may be the sum of N and M, that is, the quantity parameter is the sum of the number of the first Bluetooth device and the second Bluetooth device. Optionally, the quantity parameter may be a preset value. For example, two pairs of headphones may be preset to form the same Bluetooth device set for use, and the corresponding quantity parameter may be set to 4; or, two groups of Bluetooth speakers may be preset to form the same Bluetooth device set for use, one of which includes 2 Bluetooth speakers and the other includes 4 Bluetooth speakers, and the corresponding quantity parameter may be set to 6.

[0099] As another implementation, the user may also set the quantity parameter corresponding to the target Bluetooth device set according to actual needs. Optionally, the operation mode of the setting operation corresponding to different quantity parameters may be pre-set. When the electronic device detects the setting operation, the corresponding quantity parameter may be determined according to the operation mode of the setting operation, and the quantity parameter corresponding to the target Bluetooth device set is set to the quantity parameter corresponding to the operation mode of the setting operation. For example, the electronic device may be an earphone box, and a trigger button may be provided on the earphone box. When the user clicks the trigger button once, it indicates that the quantity parameter is set to 2. When the user clicks the trigger button twice, it indicates that the quantity parameter is set to 4, etc., but is not limited thereto; the earphone box may determine the corresponding quantity parameter according to the number of times the detected trigger button is clicked, and set the quantity parameter corresponding to the target Bluetooth device set to the corresponding quantity parameter.

[0100] Optionally, a setting interface may be provided on the electronic device, and the user may input a quantity parameter in the setting interface, and the electronic device determines the quantity parameter input by the user according to the setting operation performed by the user. Optionally, a setting interface may also be provided on the terminal device, and the electronic device is communicatively connected with the terminal device, and the user may input a quantity parameter in the setting interface, and the terminal device determines the quantity parameter input by the user according to the setting operation performed by the user, and sends the quantity parameter to the electronic device. Alternatively, the terminal device may be communicatively connected with any first Bluetooth device or any second Bluetooth device, and the terminal device determines the quantity parameter set by the user according to the setting operation performed by the user, and sends the quantity parameter to the first Bluetooth device or the second Bluetooth device in the communication connection. When the first Bluetooth device or the second Bluetooth device establishes a communication connection with the electronic device, the first Bluetooth device or the second Bluetooth device sends the quantity parameter to the electronic device for storage.

[0101] The serial number is used to indicate the arrangement number corresponding to the Bluetooth device in the target Bluetooth device set. Different Bluetooth devices in the same Bluetooth device set may correspond to different serial numbers. Optionally, when the electronic device sends the target set information to the first Bluetooth device or the second Bluetooth device, the serial number may be randomly assigned, or the serial number may be assigned in order from small to large according to the order in which the communication connection is established with the electronic device. For example, the electronic device first establishes a communication connection with N first Bluetooth devices, and may send a serial number 1 to the first first Bluetooth device that establishes a communication connection, and send a serial number 2 to the second first Bluetooth device that establishes a communication connection... and so on.

[0102] For example, Figure 4A FIG. 1 is a timing diagram of an information updating method in another embodiment. Figure 4AAs shown, the electronic device can obtain the target combination identification information in response to the first trigger operation. The electronic device can establish a communication connection with N first Bluetooth devices, and update the combination identification information, quantity parameters, serial numbers and other collection information configured in the N first Bluetooth devices. The electronic device can send an update instruction to each first Bluetooth device respectively, and the update instruction can carry target collection information such as the target combination identification information, the quantity parameter of the target Bluetooth device set, and the serial number corresponding to the first Bluetooth device in the target Bluetooth device set. After receiving the target collection information sent by the electronic device, the first Bluetooth device can update the configured collection information according to the target collection information, and can update the first combination identification information to the target combination identification information, update the quantity parameter of the first Bluetooth device set (i.e., N) to the quantity parameter of the target Bluetooth device set, and update the corresponding serial number in the first Bluetooth device set to the corresponding serial number in the target Bluetooth device set.

[0103] The electronic device can establish a communication connection with M second Bluetooth devices, and update the combination identification information, quantity parameters, serial numbers and other set information configured in the M second Bluetooth devices. The electronic device can send an update instruction to each second Bluetooth device respectively, and the update instruction can carry target set information such as target combination identification information, the quantity parameter of the target Bluetooth device set, and the serial number corresponding to the second Bluetooth device in the target Bluetooth device set. After receiving the target set information sent by the electronic device, the second Bluetooth device can update the configured set information according to the target set information, and can update the second combination identification information to the target combination identification information, update the quantity parameter of the second Bluetooth device set (i.e., M) to the quantity parameter of the target Bluetooth device set, and update the corresponding serial number in the second Bluetooth device set to the corresponding serial number in the target Bluetooth device set.

[0104] For example, Figure 4B FIG. 1 is a timing diagram of an information updating method in another embodiment. For example, the electronic device includes an earphone box, N first Bluetooth devices include a first left earphone and a first right earphone, and M second Bluetooth devices include a second left earphone and a second right earphone. Figure 4BAs shown, the user can perform a first trigger operation on the earphone box (for example, the pairing button on the dual-control earphone box), and the earphone box responds to the first trigger operation and can obtain the target SIRK. The user can put the first left earphone and the first right earphone into the earphone box respectively. The earphone box can send the target set information to the first left earphone and the first right earphone respectively when the first left earphone and the first right earphone are placed in the earphone box. The earphone box can update the SIRK, Size (i.e., quantity parameter), Rank (i.e., serial number) and other parameters configured for the first left earphone and the first right earphone respectively. The earphone box can send update instructions to the first left earphone and the first right earphone respectively to notify the first left earphone and the first right earphone to update the SIRK, Size, Rank and other parameters. After receiving the target SIRK, the Size of the target Bluetooth device set (such as 4), and the Rank of the first left earphone in the target Bluetooth device set (such as 1) and other parameters sent by the earphone box, the first left earphone can update its own SIRK from the first SIRK to the target SIRK, update the Size of the first Bluetooth device set (such as 2) to the Size of the target Bluetooth device set, and update the Rank in the first Bluetooth device set to the Rank in the target Bluetooth device set. After receiving the target SIRK, the Size of the target Bluetooth device set (such as 4), and the Rank of the first right earphone in the target Bluetooth device set (such as 2) and other parameters sent by the earphone box, the first right earphone can update its own SIRK from the first SIRK to the target SIRK, update the Size of the first Bluetooth device set (such as 2) to the Size of the target Bluetooth device set, and update the Rank in the first Bluetooth device set to the Rank in the target Bluetooth device set.

[0105] The user can take out the first left earphone and the first right earphone from the earphone box, and then put the second left earphone and the second right earphone into the earphone box respectively. The earphone box can send the target set information to the second left earphone and the second right earphone respectively when the second left earphone and the second right earphone are placed in the earphone box. The earphone box can update the parameters such as SIRK, Size, Rank, etc. configured for the second left earphone and the second right earphone respectively. The earphone box can send an update instruction to the second left earphone and the second right earphone respectively to notify the second left earphone and the second right earphone to update the parameters such as SIRK, Size, Rank, etc. After receiving the parameters such as the target SIRK, the Size of the target Bluetooth device set (such as 4), and the Rank of the second left earphone in the target Bluetooth device set (such as 3) sent by the earphone box, the second left earphone can update its own SIRK from the second SIRK to the target SIRK, update the Size of the second Bluetooth device set (such as 2) to the Size of the target Bluetooth device set, and update the Rank in the second Bluetooth device set to the Rank in the target Bluetooth device set. After receiving parameters such as the target SIRK, the Size of the target Bluetooth device set (such as 4) and the Rank of the second right earphone in the target Bluetooth device set (such as 4) sent by the earphone box, the second right earphone can update its own SIRK from the second SIRK to the target SIRK, update the Size of the second Bluetooth device set (such as 2) to the Size of the target Bluetooth device set, and update the Rank in the second Bluetooth device set to the Rank in the target Bluetooth device set.

[0106] In an embodiment of the present application, the electronic device sends target set information to N first Bluetooth devices in a first Bluetooth device set, so that the first Bluetooth device updates the first set information to the target set information. The electronic device sends the target set information to M second Bluetooth devices in a second Bluetooth device set, so that the second Bluetooth device updates the second set information to the target set information. The target set information is used to indicate the target Bluetooth device set, and the N first Bluetooth devices that originally belonged to the first Bluetooth device set and the M second Bluetooth devices that originally belonged to the second Bluetooth device set can be successfully configured to belong to the target Bluetooth device set for collaborative use. The Bluetooth devices of different Bluetooth device sets can be dynamically and flexibly grouped into the same Bluetooth device set for collaborative use, thereby meeting the user's usage needs.

[0107] In some embodiments, the target set information includes target combination identification information. Several methods for the electronic device to obtain the target combination identification information are introduced below. The electronic device may obtain the target combination identification information in any of the following methods, but is not limited to:

[0108] Acquisition method 1: Generate target combination identification information according to a preset method.

[0109] The electronic device generates target combination identification information according to a preset method, which may include: generating the target combination identification information based on the target BLE address, the target BLE address including the BLE address of any first Bluetooth device or the BLE address of any second Bluetooth device; or randomly generating a combination identification information as the target combination identification information.

[0110] The electronic device can obtain the target BLE address and generate the target combination identification information according to the target BLE address in a specific manner. Optionally, the specific method can be to directly use the target BLE address as a partial field of the target combination identification information to generate the target combination identification information. Furthermore, the target BLE address can be used as a partial field of the target combination identification information, and the partial field can be combined with the first preset field to generate the target combination identification information. The first preset field can refer to the pre-defined field information in the combination identification information, or it can be randomly generated field information. For example, the target combination identification information may include the target SIRK, and the SIRK may be 128 bytes. The BLE address (48 bytes) can be directly used as a part of the field of the target SIRK, for example, SIRK = BLE address || first preset field.

[0111] Optionally, the specific method may also be to perform a hash calculation on the target BLE address, and use the calculation result as a partial field of the target combination identification information to generate the target combination identification information. Furthermore, the calculation result may be combined with the second preset field to generate the target combination identification information, for example, SIRK=HASH‖the second preset field, where HASH represents the calculation result of hashing the target BLE address. Among them, the first preset field and the second preset field may be the same or different, and may be set according to actual conditions. Since the BLE address is unique, it can be guaranteed that the generated target combination identification information is also unique, and will not be confused with the combination identification information of other Bluetooth device sets, thereby improving the accuracy of the use of Bluetooth device sets.

[0112] As a specific implementation, the acquisition rules of the target BLE address can be set according to actual needs. Optionally, if the electronic device first establishes a communication connection with N first Bluetooth devices, the target BLE address can be the BLE address of any first Bluetooth device, and the target BLE address can also be the BLE address of the first first Bluetooth device that establishes a communication connection with the electronic device, or the BLE address of the last first Bluetooth device that establishes a communication connection with the electronic device, etc. Optionally, if the electronic device first establishes a communication connection with M second Bluetooth devices, the target BLE address can be the BLE address of any second Bluetooth device, and the target BLE address can also be the BLE address of the first second Bluetooth device that establishes a communication connection with the electronic device, or the BLE address of the last second Bluetooth device that establishes a communication connection with the electronic device, etc. The electronic device obtains the target BLE address according to the preset acquisition rules, which can ensure that the target combination identification information is generated in time and sent to the N first Bluetooth devices and the M second Bluetooth devices, thereby improving efficiency.

[0113] In some embodiments, the electronic device may also randomly generate a combination identification information as the target combination identification information, and the electronic device may pre-store various fields of the target combination identification information, and randomly generate field values ​​in various fields to obtain unique target combination identification information, thereby improving the accuracy of the use of the Bluetooth device set. It should be noted that the electronic device may also generate the target combination identification information in other ways, and is not limited to the above-mentioned ways.

[0114] In an embodiment of the present application, the electronic device can generate target combination identification information according to a preset method, which can ensure that the generated target combination identification information is unique, avoid confusion with other Bluetooth device sets, and ensure that N first Bluetooth devices and M second Bluetooth devices are successfully added to the target Bluetooth device set to meet the user's usage needs.

[0115] Acquisition method 2: using the combination identification information stored in the electronic device as the target combination identification information.

[0116] The electronic device may pre-store target combination identification information. When the electronic device establishes a communication connection with N first Bluetooth devices, the pre-stored target combination identification information may be sent to the N first Bluetooth devices. After receiving the target combination identification information sent by the electronic device, the first Bluetooth device may determine whether its own combination identification information (i.e., the first combination identification information) is the same as the target combination identification information. If they are not the same, the first Bluetooth device may update its own combination identification information to the target combination identification information. If they are the same, no update is required.

[0117] As a specific implementation, the combined identification information includes SIRK. For example, if the SIRK stored in the electronic device is SIRK3, the SIRK3 can be sent as the target SIRK to N first Bluetooth devices. If the first SIRK currently configured by the first Bluetooth device is SIKR1, after the first Bluetooth device receives the target SIRK sent by the electronic device, since the target SIRK is different from the first SIRK, the first SIRK can be updated to the target SIRK, that is, its own SIRK is updated from SIKR1 to SIRK3. For another example, if the SIRK stored in the electronic device is SIRK1, the SIRK1 can be sent as the target SIRK to N first Bluetooth devices. If the first SIRK currently configured by the first Bluetooth device is also SIKR1, after the first Bluetooth device receives the target SIRK sent by the electronic device, since the target SIRK is the same as the first SIRK (both are SIRK1), no update is required.

[0118] When the electronic device establishes a communication connection with M second Bluetooth devices, the pre-stored target combination identification information can be sent to the M second Bluetooth devices. After receiving the target combination identification information sent by the electronic device, the second Bluetooth device can determine whether its own combination identification information (i.e., the second combination identification information) is the same as the target combination identification information. If they are not the same, the second Bluetooth device can update its own combination identification information to the target combination identification information. If they are the same, no update is required.

[0119] In an embodiment of the present application, the electronic device can send the pre-stored combination identification information as the target combination identification information to N first Bluetooth devices and M second Bluetooth devices respectively, so that the N first Bluetooth devices originally belonging to the first Bluetooth device set and the M second Bluetooth devices originally belonging to the second Bluetooth device set are successfully configured to belong to the target Bluetooth device set for collaborative use to meet the user's usage needs.

[0120] Acquisition method three: acquiring the combination identification information currently configured by the target Bluetooth device as the target combination identification information, where the target Bluetooth device is any first Bluetooth device or any second Bluetooth device.

[0121] The electronic device may select any first Bluetooth device or any second Bluetooth device of the communication connection as the target Bluetooth device, and obtain the combination identification information of the target Bluetooth device currently configured from the target Bluetooth device. Optionally, if the electronic device selects any first Bluetooth device of the communication connection as the target Bluetooth device, then after obtaining the combination identification information of the target Bluetooth device currently configured as the target combination identification information, the target combination identification information may not be sent to the N first Bluetooth devices, but only to the M second Bluetooth devices. Similarly, if the electronic device selects any second Bluetooth device of the communication connection as the target Bluetooth device, then after obtaining the combination identification information of the target Bluetooth device currently configured as the target combination identification information, the target combination identification information may not be sent to the M second Bluetooth devices, but only to the N first Bluetooth devices. The information update efficiency of the Bluetooth device can be improved.

[0122] Furthermore, the combined identification information includes SIRK. For example, the electronic device selects any first Bluetooth device as the target Bluetooth device. If the SIRK currently configured for the first Bluetooth device is SIRK1 (i.e., the first SIRK), the electronic device can obtain SIRK1 from the first Bluetooth device, and use SIRK1 as the target SIRK, and then send the target SIRK to the second Bluetooth device, so that the second Bluetooth device updates its own SIRK to the target SIRK (i.e., SIRK1). After the second Bluetooth device completes the SIRK update, the N first Bluetooth devices and the M second Bluetooth devices are all configured with the same SIRK (all SIRK1), so that they can be identified as belonging to the same set of Bluetooth devices for collaborative use.

[0123] As a specific implementation, the above-mentioned target Bluetooth device can be a Bluetooth device in the first Bluetooth device set and the second Bluetooth device set that first establishes a communication connection with the electronic device. For example, the electronic device first establishes a communication connection with the N first Bluetooth devices in the first Bluetooth device set, and the target Bluetooth device can be any first Bluetooth device. Furthermore, the target Bluetooth device can be the first first Bluetooth device that establishes a communication connection with the electronic device. This ensures that the electronic device can obtain the target combination identification information in a timely manner, and ensures the success rate and efficiency of configuring the N first Bluetooth devices that originally belonged to the first Bluetooth device set and the M second Bluetooth devices that originally belonged to the second Bluetooth device set to belong to the target Bluetooth device set for collaborative use.

[0124] In an embodiment of the present application, the electronic device can obtain the combination identification information currently configured by the target Bluetooth device as the target combination identification information and send it to N first Bluetooth devices and M second Bluetooth devices, where the target Bluetooth device is any first Bluetooth device or any second Bluetooth device, so that the first Bluetooth device and the second Bluetooth device are configured with the same target combination identification information, and the N first Bluetooth devices that originally belonged to the first Bluetooth device set and the M second Bluetooth devices that originally belonged to the second Bluetooth device set can be successfully configured to belong to the target Bluetooth device set for collaborative use.

[0125] It should be noted that the combination identification information involved in the above embodiments may include other combination identification information in addition to SIRK. For example, if the Bluetooth devices under the same Bluetooth device set use the same Bluetooth address to establish Bluetooth communication connections with external devices, the combination identification information may include the Bluetooth address, etc., but is not limited to this.

[0126] like Figure 5 As shown, in another embodiment, an information updating method is provided, which can be applied to the above electronic device, and the method may include the following steps:

[0127] Step 510: Acquire target set information, where the target set information is used to indicate a target Bluetooth device set.

[0128] Step 520: Send the target set information to N first Bluetooth devices in the first Bluetooth device set, so that the first Bluetooth devices update the first set information to the target set information; the first set information is used to indicate the first Bluetooth device set.

[0129] Step 530: Send the target set information to M second Bluetooth devices in the second Bluetooth device set, so that the second Bluetooth devices update the second set information to the target set information; the second set information is used to indicate the second Bluetooth device set.

[0130] For the description of steps 510 to 530 , reference may be made to the relevant description in the above embodiments, which will not be repeated here.

[0131] In some embodiments, after N first Bluetooth devices update the first set information to target set information, and M second Bluetooth devices update the second set information to target set information, the N first Bluetooth devices and the M second Bluetooth devices can respectively establish LE Audio Bluetooth connections with the terminal device based on the target set information, so as to enable the N first Bluetooth devices and the M second Bluetooth devices to share the audio transmitted by the terminal device.

[0132] The first Bluetooth device may send an LE Audio broadcast signal based on the target set information to trigger the terminal device to establish an LE Audio Bluetooth connection with the first Bluetooth device. The second Bluetooth device may also send an LE Audio broadcast signal based on the target set information to trigger the terminal device to establish an LE Audio Bluetooth connection with the second Bluetooth device.

[0133] Optionally, when the terminal device first receives an LE Audio broadcast signal sent by a Bluetooth device in the target Bluetooth device set, the device information corresponding to the Bluetooth device (such as BLE address, device name, etc.) can be displayed on the Bluetooth connection interface. After the user determines to connect the terminal device to the Bluetooth device, the terminal device can respond to the connection operation, establish an LE Audio Bluetooth connection with the Bluetooth device, and obtain the target set information corresponding to the Bluetooth device. Optionally, the terminal device can receive the target set information sent by the Bluetooth device during the process of establishing an LE Audio Bluetooth connection with the Bluetooth device.

[0134] In some embodiments, the target set information includes target combination identification information, and each Bluetooth device belonging to the target Bluetooth device set sends an LE Audio broadcast signal based on the same target combination identification information. After the terminal device establishes an LE Audio Bluetooth connection with a Bluetooth device in the target Bluetooth device set for the first time, if it receives an LE Audio broadcast signal sent by another Bluetooth device again, it can determine whether the combination identification information corresponding to the other Bluetooth device is the same as the combination identification information corresponding to the Bluetooth device connected for the first time based on the LE Audio broadcast signal sent by the other Bluetooth device. If they are the same, it can be determined that the other Bluetooth device belongs to the same Bluetooth device set as the Bluetooth device connected for the first time, and automatically sends a Bluetooth connection request to the other Bluetooth device to establish an LE Audio Bluetooth connection with the other Bluetooth device.

[0135] As a specific implementation, each Bluetooth device belonging to the target Bluetooth device set sends a LE Audio broadcast signal based on the same target SIRK. When the terminal device receives the LE Audio broadcast signal sent by a Bluetooth device in the target Bluetooth device set for the first time, it can establish an LE Audio Bluetooth connection with the Bluetooth device and obtain the SIRK corresponding to the Bluetooth device (i.e., the target SIRK). As an implementation, the terminal device can receive the SIRK sent by the Bluetooth device during the process of establishing an LE Audio Bluetooth connection with the Bluetooth device. The LE Audio Bluetooth connection is established on the basis of the BLE connection. The process of establishing the LE Audio Bluetooth connection may include querying some device parameters based on the BLE connection. The query of the device parameters may include a SIRK query of the Bluetooth device. After the LE Audio Bluetooth connection is established, when there is a business demand, a CIS (Connected Isochronous Streams) channel may be established for business transmission.

[0136] If the terminal device receives the LE Audio broadcast signal sent by another Bluetooth device again, it can determine whether the SIRK corresponding to the other Bluetooth device is the same as the target SIRK based on the LE Audio broadcast signal sent by the other Bluetooth device. If they are the same, it will automatically send a Bluetooth connection request to the other Bluetooth device and establish an LE Audio Bluetooth connection with the other Bluetooth device.

[0137] As an implementation method, the LE Audio broadcast signal sent by the Bluetooth device may include a target field calculated based on the target SIRK. After the terminal device receives the LE Audio broadcast signal sent by another Bluetooth device, it can parse the LE Audio broadcast signal sent by the other Bluetooth device to obtain the target specific broadcast information and target field carried by the LE Audio broadcast signal, and calculate the target local value based on the SIRK (i.e., target SIRK) corresponding to the Bluetooth device connected for the first time and the target specific broadcast information. If the target local value is the same as the target field, it can be determined that the Bluetooth device connected for the first time and the other Bluetooth device belong to the same Bluetooth device set.

[0138] Specifically, Figure 6As shown, the LE Audio broadcast signal may include RSI (resolvable Set Identifier), and RSI may include two parts: 1. A hash sequence 610 generated by the SIRK corresponding to the Bluetooth device; 2. A random sequence 620 generated by a random number. The hash sequence 610 may be calculated by the formula: hash = sih (SIKR, prand), where hash represents the hash sequence 610 and prand represents the random sequence 620. The target specific broadcast information obtained by the electronic device parsing the LE Audio broadcast signal sent by another Bluetooth device may be a random sequence of RSI, and the target field may be a hash sequence of RSI carried by the LE Audio broadcast signal. The electronic device may calculate the target local value by the above formula based on the SIRK corresponding to the Bluetooth device connected for the first time (i.e., the target SIRK) and the random sequence in the parsed RSI, and compare the target local value with the hash sequence of the parsed RSI. If the two are consistent, it means that the SIKR of the Bluetooth device connected for the first time is the same as the SIRK of the other Bluetooth device (both are target SIRKs), and it can be determined that the Bluetooth device connected for the first time and the other Bluetooth device belong to the same Bluetooth device set.

[0139] In some embodiments, after determining that the combination identification information corresponding to another Bluetooth device is the same as the combination identification information corresponding to the Bluetooth device connected for the first time, the terminal device may determine whether the number of currently connected Bluetooth devices belonging to the target Bluetooth device set has reached the number parameter. If the number parameter has been reached, an LE Audio Bluetooth connection may not be established with the other Bluetooth device. For example, when the terminal device first establishes an LE Audio Bluetooth connection with a Bluetooth device in the target Bluetooth device set, the number parameter of the target Bluetooth device set is obtained as 4. When the terminal device has established an LE Audio Bluetooth connection with 4 Bluetooth devices in the target Bluetooth device set, and receives an LE Audio broadcast signal sent by another Bluetooth device, and the combination identification information corresponding to the other Bluetooth device is also the target combination identification information, the terminal device does not establish an LE Audio Bluetooth connection with the other Bluetooth device, which can ensure the accuracy of the Bluetooth connection and further ensure the accuracy of subsequent audio sharing.

[0140] In some embodiments, after determining that the combination identification information corresponding to another Bluetooth device is the same as the combination identification information corresponding to the Bluetooth device connected for the first time, the terminal device can determine whether the serial number corresponding to the other Bluetooth device in the target Bluetooth device set conflicts with the currently connected Bluetooth device belonging to the target Bluetooth device set. If there is a conflict, the LE Audio Bluetooth connection is not established with the other Bluetooth device. For example, when the terminal device establishes an LE Audio Bluetooth connection with a Bluetooth device in the target Bluetooth device set for the first time, the serial number corresponding to the Bluetooth device connected for the first time is obtained as 1. If the terminal device receives an LE Audio broadcast signal sent by another Bluetooth device, the combination identification information corresponding to the other Bluetooth device is also the target combination identification information, and the serial number corresponding to the other Bluetooth device is also 1, there is a serial number conflict with the Bluetooth device connected for the first time, which may indicate that an error has occurred in the connection. In this case, the LE Audio Bluetooth connection is not established with the other Bluetooth device, which can ensure the accuracy of the Bluetooth connection and further ensure the accuracy of subsequent audio sharing.

[0141] As another implementation, the terminal device may also first establish an LE Audio Bluetooth connection with another Bluetooth device after determining that the combination identification information corresponding to the other Bluetooth device is the same as the combination identification information corresponding to the Bluetooth device connected for the first time. Then, it is determined whether the number of Bluetooth devices currently connected to the target Bluetooth device set has exceeded the quantity parameter, and whether the serial number corresponding to the other Bluetooth device in the target Bluetooth device set conflicts with other Bluetooth devices connected to the terminal device and belonging to the target Bluetooth device set. If the number of Bluetooth devices currently connected to the target Bluetooth device set has exceeded the quantity parameter, or the serial number corresponding to the other Bluetooth device conflicts with the serial numbers corresponding to other connected Bluetooth devices, the LE Audio Bluetooth connection with the other Bluetooth device is disconnected.

[0142] It should be noted that the process of establishing LE Audio Bluetooth connections between the terminal device and each Bluetooth device in the target Bluetooth device set (including N first Bluetooth devices and M second Bluetooth devices) can be performed according to the process described in the above embodiment.

[0143] After the terminal device establishes LE Audio Bluetooth connections with N first Bluetooth devices and M second Bluetooth devices respectively, it can send audio data to the N first Bluetooth devices and M second Bluetooth devices respectively, so that the N first Bluetooth devices and M second Bluetooth devices share the audio data sent by the terminal device.

[0144] Example diagram, Fig. 7A FIG. 1 is a timing diagram of N first Bluetooth devices and M second Bluetooth devices sharing audio data transmitted by a terminal device in an embodiment. Fig. 7AAs shown, after the first Bluetooth device updates the target set information such as the target combination identification information, quantity parameters and serial number according to the update instruction sent by the electronic device, it can send a LE Audio broadcast signal. The terminal device can turn on the scanning mode, and when the LE Audio broadcast signal sent by the first first Bluetooth device is scanned for the first time, the device information corresponding to the first first Bluetooth device can be displayed, and the user can determine whether to allow the terminal device to establish a Bluetooth connection with the first first Bluetooth device. If the terminal device detects a connection operation, it can respond to the connection operation, establish an LE Audio Bluetooth connection with the first first Bluetooth device, and obtain the target combination identification information corresponding to the first first Bluetooth device. When the terminal device scans the LE Audio broadcast signal sent by the Xth first Bluetooth device, it can determine whether the Xth first Bluetooth device and the first first Bluetooth device belong to the same Bluetooth device set. If it is determined that the Xth first Bluetooth device and the first first Bluetooth device belong to the same Bluetooth device set (both belong to the target Bluetooth device set), an LE Audio Bluetooth connection can be established with the Xth first Bluetooth device. Wherein, X can be an integer greater than 1 and less than or equal to N.

[0145] After the second Bluetooth device updates the target set information such as the target combination identification information, quantity parameters and serial number according to the update instruction sent by the electronic device, it can send an LE Audio broadcast signal. When the terminal device scans the LE Audio broadcast signal sent by the Yth second Bluetooth device, it can determine whether the Yth second Bluetooth device and the first first Bluetooth device belong to the same Bluetooth device set. If it is determined that the Yth second Bluetooth device and the first first Bluetooth device belong to the same Bluetooth device set (both belong to the target Bluetooth device set), an LE Audio Bluetooth connection can be established with the Yth second Bluetooth device. Wherein, X can be an integer greater than 0 and less than or equal to M.

[0146] After the terminal device establishes LE Audio Bluetooth connections with N first Bluetooth devices and M second Bluetooth devices respectively, it can send audio data to the N first Bluetooth devices and M second Bluetooth devices respectively, so that the N first Bluetooth devices and M second Bluetooth devices share the audio data sent by the terminal device.

[0147] In an embodiment of the present application, the terminal device can respectively establish LE Audio Bluetooth connections with N first Bluetooth devices and M second Bluetooth devices whose target set information has been updated, and send audio data to the N first Bluetooth devices and M second Bluetooth devices, thereby realizing audio sharing between the N first Bluetooth devices and the M second Bluetooth devices, and improving the reliability of audio data transmission.

[0148] Step 540, in response to the second trigger operation, sending an information recovery instruction to N first Bluetooth devices, the information recovery instruction is used to instruct the first Bluetooth devices to restore the target set information to the first set information; and / or, sending an information recovery instruction to M second Bluetooth devices, the information recovery instruction is used to instruct the second Bluetooth devices to restore the target set information to the second set information.

[0149] In some embodiments, the user can perform a second trigger operation on the electronic device to trigger the electronic device to restore the N first Bluetooth devices and M second Bluetooth devices in the target Bluetooth device set to independent use, so that the N first Bluetooth devices and M second Bluetooth devices can be restored to belong to different Bluetooth device sets, that is, the N first Bluetooth devices belong to the first Bluetooth device set, and the M second Bluetooth devices belong to the second Bluetooth device set, and they are no longer used collaboratively.

[0150] The specific operation mode of the second trigger operation is not limited in the embodiments of the present application. For example, a specific button may be provided on the electronic device, and the specific button may be a virtual button or a physical button. The first trigger operation may be a preset operation on the specific button (such as long pressing for a period of time, clicking a specific button, double-clicking a specific button, etc.); for another example, the second trigger operation may be any one of a touch operation, a gesture operation, a voice operation, etc., and the electronic device may detect the second trigger operation through a corresponding sensor (such as detecting a preset pressing operation through a pressure sensor, detecting a preset gesture operation through a distance sensor, detecting a preset voice content through a voice sensor, etc.), but is not limited thereto. The second trigger operation may be the same as the first trigger operation in the above embodiment, or may be different from the first trigger operation.

[0151] Exemplarily, the electronic device is an earphone box, the N first Bluetooth devices include a first left earphone and a first right earphone, and the M second Bluetooth devices include a second left earphone and a second right earphone. The second trigger operation may be to place the first left earphone and the first right earphone in the earphone box and long press the pairing button on the earphone box, or the second trigger operation may be to place the first left earphone and the first right earphone in the earphone box and close the lid of the earphone box. When the first left earphone and the first right earphone are placed in the earphone box, the earphone box may send an information recovery instruction to the first left earphone and the first right earphone respectively, and the first left earphone and the first right earphone may restore the target set information to the first set information according to the information recovery instruction. When the second left earphone and the second right earphone are placed in the earphone box, the earphone box may send an information recovery instruction to the second left earphone and the second right earphone respectively, and the second left earphone and the second right earphone may restore the target set information to the second set information according to the information recovery instruction.

[0152] For example, Figure 7BFIG. 1 is a timing diagram of another embodiment in which N first Bluetooth devices and M second Bluetooth devices share audio data transmitted by a terminal device. Figure 7B As shown, take an electronic device including an earphone box, N first Bluetooth devices including a first left earphone and a first right earphone, and M second Bluetooth devices including a second left earphone and a second right earphone as an example. After the first left earphone is updated according to parameters such as the target SIRK sent by the earphone box, the Size of the target Bluetooth device set, and the Rank of the first left earphone in the target Bluetooth device set, an LE Audio broadcast signal can be sent. The terminal device can turn on the scanning mode, and when the LE Audio broadcast signal sent by the first left earphone is scanned, the device information corresponding to the first left earphone can be displayed, and the user can determine whether to allow the terminal device to establish a Bluetooth connection with the first left earphone. If the terminal device detects a connection operation, it can respond to the connection operation, initiate an LE Audio connection request to the first left earphone, establish an LE Audio Bluetooth connection with the first left earphone, and obtain the target SIRK corresponding to the first left earphone.

[0153] After the first right earphone is updated according to the parameters such as the target SIRK sent by the earphone box, the Size of the target Bluetooth device set, and the Rank of the first right earphone in the target Bluetooth device set, an LE Audio broadcast signal can also be sent. When the terminal device scans the LE Audio broadcast signal sent by the first right earphone, it can determine whether the first right earphone and the first left earphone belong to the same Bluetooth device set (that is, determine whether they correspond to the same target SIRK). If it is determined that the first right earphone and the first left earphone belong to the same Bluetooth device set (both belong to the target Bluetooth device set), an LE Audio connection request can be automatically initiated to the first right earphone, and an LE Audio Bluetooth connection can be established with the first right earphone.

[0154] After the second left earphone is updated according to the target SIRK sent by the earphone box, the Size of the target Bluetooth device set, and the Rank of the second left earphone in the target Bluetooth device set, the LE Audio broadcast signal can be sent. When the terminal device scans the LE Audio broadcast signal sent by the second left earphone, it can determine whether the second left earphone and the first left earphone belong to the same Bluetooth device set. If it is determined that the second left earphone and the first left earphone belong to the same Bluetooth device set (both belong to the target Bluetooth device set), it can automatically initiate an LE Audio connection request to the second left earphone and establish an LE Audio Bluetooth connection with the second left earphone.

[0155] After the second right earphone is updated according to the target SIRK sent by the earphone box, the Size of the target Bluetooth device set, and the Rank of the second right earphone in the target Bluetooth device set, the LE Audio broadcast signal can also be sent. When the terminal device scans the LE Audio broadcast signal sent by the second right earphone, it can determine whether the second right earphone and the first left earphone belong to the same Bluetooth device set. If it is determined that the second right earphone and the first left earphone belong to the same Bluetooth device set (both belong to the target Bluetooth device set), it can automatically initiate an LE Audio connection request to the second right earphone and establish an LE Audio Bluetooth connection with the second right earphone.

[0156] In this way, the terminal device can establish LE Audio Bluetooth connections with the two pairs of headphones respectively, and identify the two pairs of headphones as the same Bluetooth device set, and use the two pairs of headphones in a collaborative manner. When the terminal device plays audio, the terminal device can establish CIS connections with the first left earphone, the first right earphone, the second left earphone and the second right earphone respectively, and transmit audio data to the first left earphone, the first right earphone, the second left earphone and the second right earphone to achieve audio sharing of the two pairs of headphones. Furthermore, the terminal device can send left channel audio data to the first left earphone and the second left earphone respectively, and send right channel audio data to the first right earphone and the second right earphone respectively, so that the first left earphone and the second left earphone share the same left channel audio data, and the first right earphone and the second right earphone share the same left channel audio data. Each earphone in the two pairs of headphones can keep the service information unchanged, so that each earphone can maintain the original audio playback properties (such as the left earphone supports left channel audio playback, and the right earphone supports right channel audio playback). The terminal device can establish a CIS channel with each earphone in the two pairs of headphones respectively, and send corresponding audio data to each earphone through the established CIS channel, thereby sharing audio data between the two pairs of headphones. In this audio sharing solution, no additional hardware costs are required, and better compatibility can be provided, further ensuring the reliability of transmission.

[0157] When the user wants to end the sharing mode between the two pairs of headphones, a second trigger operation can be performed (for example, putting the first left earphone and the first right earphone, or the second left earphone and the second right earphone into the earphone box and closing the earphone box), then the earphone box can send an information recovery instruction to the first left earphone and the first right earphone placed in the earphone box, so that the first left earphone and the first right earphone placed in the earphone box restore the target SIRK to the first SIRK, restore the Size of the target Bluetooth device set to the Size of the first Bluetooth device set, and restore the Rank in the target Bluetooth device set to the Rank in the first Bluetooth device set. Alternatively, the earphone box can send an information recovery instruction to the second left earphone and the second right earphone placed in the earphone box, so that the second left earphone and the second right earphone placed in the earphone box restore the target SIRK to the second SIRK, restore the Size of the target Bluetooth device set to the Size of the second Bluetooth device set, and restore the Rank in the target Bluetooth device set to the Rank in the second Bluetooth device set.

[0158] In an embodiment of the present application, N first Bluetooth devices that originally belonged to a first Bluetooth device set and M second Bluetooth devices that originally belonged to a second Bluetooth device set can be successfully configured to belong to a target Bluetooth device set for collaborative use, and the N first Bluetooth devices and M second Bluetooth devices in the target Bluetooth device set can be restored to belong to different Bluetooth device sets for independent use.
