Description

Bluetooth connection method, readable storage medium, and electronic device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on June 21, 2023, with application number 202310748328.0 and application name “Bluetooth connection method, readable storage medium and electronic device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a Bluetooth connection method, a readable storage medium, and an electronic device. Background Art

[0003] If the Bluetooth communication connection between Bluetooth device A and Bluetooth device B is disconnected, for example, because Bluetooth device A is preempted by Bluetooth device C, the user can restart Bluetooth device B to trigger the preemption function of Bluetooth device B and reconnect Bluetooth device B to Bluetooth device A. However, restarting Bluetooth device B is cumbersome and time-consuming, affecting the user experience.

[0004] For example, referring to Figure 1 , a Bluetooth headset 20 (Bluetooth device A) has established a Bluetooth communication connection with a mobile phone 10 (Bluetooth device B), and mobile phone 10 is playing audio through the Bluetooth headset 20. Since the last Bluetooth device connected to the vehicle computer 30 (Bluetooth device C) was mobile phone 10, when the vehicle computer 30 starts up, it will preempt the mobile phone 10 and establish a Bluetooth communication connection with the mobile phone 10, causing the mobile phone 10 to play audio through the speakers in the vehicle computer 30. This will cause the communication connection between the Bluetooth headset 20 and the mobile phone 10 to be disconnected, affecting the user experience. If the user wants to resume playing the audio from the mobile phone 10 through the Bluetooth headset 20, they need to restart the Bluetooth headset 20, which is cumbersome and time-consuming, affecting the user experience.

[0005] Summary of the Invention

[0006] In view of this, the present application provides a Bluetooth connection method, a readable storage medium, and an electronic device.

[0007] In a first aspect, the present application provides a Bluetooth connection method, which includes: a first Bluetooth device detects that a first Bluetooth communication connection between the first Bluetooth device and the second Bluetooth device is disconnected; the first Bluetooth device detects a user's reconnection operation and establishes a second Bluetooth communication connection between the first Bluetooth device and the second Bluetooth device, wherein the first Bluetooth device is in a powered-on state during the period from when the first Bluetooth communication connection is disconnected to when the second Bluetooth communication connection is established.

[0008] In this method, the user does not need to restart the first Bluetooth device, but can re-establish the Bluetooth communication connection between the first Bluetooth device and the second Bluetooth device by performing a reconnection operation. The operation is convenient and helps to improve the user experience.

[0009] Optionally, the reconnection operation may be an operation performed by the user on the first Bluetooth device.

[0010] Optionally, the reconnection operation may also be an operation performed by the user on another electronic device (eg, an accessory device of the first Bluetooth device), and sent by the other electronic device to the first Bluetooth device.

[0011] In a possible implementation of the first aspect, the first Bluetooth device is a Bluetooth headset.

[0012] In a possible implementation of the above-mentioned first aspect, the above-mentioned first Bluetooth device includes a first button or a first sensor, and the reconnection operation includes at least one of the following operations: a single short press operation of the first button by the user, multiple consecutive short press operations of the first button by the user, a long press operation of the first button by the user, a touch operation of the first sensor by the user, a tapping operation of the first sensor by the user, and a pressing operation of the first sensor by the user.

[0013] In this implementation, the user can trigger the re-establishment of the Bluetooth communication connection between the first Bluetooth device and the second Bluetooth device through the reconnection operation on the first Bluetooth device. The operation is convenient and helps to improve the user experience.

[0014] Optionally, the first button may be a mechanical button, a touch button, or a button of other forms.

[0015] Optionally, the first sensor may be any one of a touch sensor, a pressure sensor, a proximity light sensor, a distance sensor, and a vibration sensor.

[0016] In a possible implementation of the first aspect, the first Bluetooth device detecting a reconnection operation by a user includes:

[0017] The first Bluetooth device receives a reconnection message sent by the earphone box corresponding to the first Bluetooth device, and the reconnection message indicates that the earphone box detects at least one of the following operations: the user opens and / or closes the lid of the earphone box; the user performs a single short press operation, or multiple consecutive short press operations, or a long press operation on the second button on the earphone box; the user touches the second sensor on the earphone box, the user taps the second sensor, or the user presses the second sensor.

[0018] In this implementation, a user can trigger a reconnection operation on an accessory device (e.g., a headset box) corresponding to a first Bluetooth device to send a reconnection message to the first Bluetooth device, indicating the user's reconnection operation. The first Bluetooth device can then respond to the reconnection message and re-establish the Bluetooth communication connection between the first Bluetooth device and the second Bluetooth device, which is convenient and helps improve the user experience.

[0019] Optionally, the second button may be a mechanical button, a touch button, or a button of other forms.

[0020] Optionally, the second sensor may be any one of a touch sensor, a pressure sensor, a proximity light sensor, a distance sensor, and a vibration sensor.

[0021] In a possible implementation of the first aspect, during the period from when the first Bluetooth communication connection is disconnected to when the second Bluetooth communication connection is established, the first Bluetooth device has not established a Bluetooth communication connection with the third Bluetooth device.

[0022] In a possible implementation of the first aspect above, the above-mentioned establishment of the second Bluetooth communication connection between the first Bluetooth device and the second Bluetooth device includes: the first Bluetooth device plays a first prompt message, and the first prompt message indicates a first operation for canceling the establishment of the second Bluetooth communication connection; when the first Bluetooth device does not detect the first operation, the first Bluetooth device establishes the second Bluetooth communication connection between the first Bluetooth device and the second Bluetooth device.

[0023] In this implementation, if the user accidentally triggers a reconnection operation, the second Bluetooth communication connection between the first and second Bluetooth devices can be canceled by performing a first operation. If the first Bluetooth device detects the first operation, it does not establish the second Bluetooth communication connection between the first and second Bluetooth devices; if it does not detect the first operation, it establishes the second Bluetooth communication connection between the first and second Bluetooth devices. This prevents reconnection between the first and second Bluetooth devices due to user error, improving the user experience.

[0024] In a possible implementation of the first aspect above, the above-mentioned establishment of the second Bluetooth communication connection between the first Bluetooth device and the second Bluetooth device includes: the first Bluetooth device plays a second prompt message, and the second prompt message indicates a second operation for confirming the establishment of the second Bluetooth communication connection; when the first Bluetooth device detects the second operation, the first Bluetooth device establishes the second Bluetooth communication connection between the first Bluetooth device and the second Bluetooth device.

[0025] In this implementation, if the user accidentally triggers the reconnection operation, the second operation to cancel the second Bluetooth communication connection between the first and second Bluetooth devices can be omitted. If the first Bluetooth device detects the second operation, it establishes the second Bluetooth communication connection between the first and second Bluetooth devices; if it does not detect the second operation, it does not establish the second Bluetooth communication connection between the first and second Bluetooth devices. This prevents the first and second Bluetooth devices from reconnecting due to user error, improving the user experience.

[0026] In a possible implementation of the first aspect, the method further includes: if the first Bluetooth device does not detect a reconnection operation within a first time period after the first Bluetooth communication connection is disconnected, turning off the first Bluetooth device.

[0027] In this implementation, the first Bluetooth device can be turned off in time to reduce the power consumption of the first Bluetooth device and improve the battery life of the first Bluetooth device.

[0028] In second aspect, the present application provides a Bluetooth connection method, which includes: a Bluetooth headset detects that a third Bluetooth communication connection with a fourth Bluetooth device is disconnected; in response to a user's reconnection operation on an earphone box of the Bluetooth headset, the earphone box sends a connection instruction to the Bluetooth headset; in response to the connection instruction, the Bluetooth headset establishes a fourth Bluetooth communication connection with the fourth Bluetooth device, wherein, during the period from the disconnection of the third Bluetooth communication connection to the establishment of the fourth Bluetooth communication connection, the Bluetooth headset is in a turned-on state.

[0029] In this method, the user does not need to restart the Bluetooth headset. Instead, the user performs a reconnection operation on the headset box of the Bluetooth headset, which triggers the Bluetooth headset to send a connection instruction to the first Bluetooth device, instructing the Bluetooth headset to re-establish a Bluetooth communication connection with the last connected Bluetooth device (the fourth Bluetooth device). The Bluetooth headset can then respond to the connection instruction to establish a Bluetooth communication connection between the first Bluetooth device and the second Bluetooth device. This method is convenient to operate and helps improve the user experience.

[0030] In a possible implementation of the second aspect above, the reconnection operation includes any one of the following operations: the user opening and / or closing the cover of the earphone box; the user performing a single short press operation, or multiple consecutive short press operations, or a long press operation on the second button on the earphone box; the user touching the second sensor on the earphone box, the user tapping the second sensor, and the user pressing the second sensor.

[0031] Optionally, the second button may be a mechanical button, a touch button, or a button of other forms.

[0032] Optionally, the second sensor may be any one of a touch sensor, a pressure sensor, a proximity light sensor, a distance sensor, and a vibration sensor.

[0033] In a possible implementation of the second aspect, during the period from when the third Bluetooth communication connection is disconnected to when the fourth Bluetooth communication connection is established, the Bluetooth headset has not established a Bluetooth communication connection with the fifth Bluetooth device.

[0034] In a possible implementation of the second aspect above, the above-mentioned Bluetooth headset establishes a fourth Bluetooth communication connection with a fourth Bluetooth device, including: the Bluetooth headset plays a first prompt message, and the first prompt message indicates a first operation for canceling the establishment of the fourth Bluetooth communication connection; when the Bluetooth headset does not detect the first operation, the Bluetooth headset establishes the fourth Bluetooth communication connection between the Bluetooth headset and the fourth Bluetooth device.

[0035] In this implementation, if the user accidentally triggers a reconnection operation, the fourth Bluetooth communication connection between the Bluetooth headset and the fourth Bluetooth device can be canceled by performing the first operation. If the Bluetooth headset detects the first operation, it will not establish the fourth Bluetooth communication connection between the Bluetooth headset and the fourth Bluetooth device; if it does not detect the first operation, it will establish the second Bluetooth communication connection between the Bluetooth headset and the fourth Bluetooth device. This prevents the Bluetooth headset and the fourth Bluetooth device from reconnecting due to user error, which is beneficial to improving the user experience.

[0036] In a possible implementation of the second aspect above, the above-mentioned Bluetooth headset establishes a fourth Bluetooth communication connection with a fourth Bluetooth device, including: the Bluetooth headset plays a second prompt message, and the second prompt message indicates a second operation for confirming the establishment of the fourth Bluetooth communication connection; when the Bluetooth headset detects the second operation, the Bluetooth headset establishes a fourth Bluetooth communication connection between the Bluetooth headset and the fourth Bluetooth device.

[0037] In this implementation, if the user accidentally triggers the reconnection operation, the second operation to cancel the fourth Bluetooth communication connection between the Bluetooth headset and the fourth Bluetooth device can be omitted. If the Bluetooth headset detects the second operation, it establishes the fourth Bluetooth communication connection between the Bluetooth headset and the fourth Bluetooth device; if it does not detect the second operation, it does not establish the fourth Bluetooth communication connection between the Bluetooth headset and the fourth Bluetooth device. This prevents the Bluetooth headset and the fourth Bluetooth device from reconnecting due to user error, thereby improving the user experience.

[0038] In a third aspect, the present application provides a readable storage medium, which stores instructions. When the instructions are executed by an electronic device, the electronic device implements various possible implementations of the above-mentioned first aspect and the above-mentioned second aspect, or any one of the methods provided by the above-mentioned second aspect and the various possible implementations of the above-mentioned second aspect.

[0039] In a fourth aspect, the present application provides an electronic device, comprising: a memory for storing instructions; a processor for executing instructions so that the electronic device implements the various possible implementations of the above-mentioned first aspect and the above-mentioned second aspect, or any one of the methods provided by the above-mentioned second aspect and the various possible implementations of the above-mentioned second aspect.

[0040] In a fifth aspect, an embodiment of the present application provides a program product, which, when running on an electronic device, enables the electronic device to implement various possible implementations of the above-mentioned first aspect and the above-mentioned second aspect, or any one of the methods provided by the above-mentioned second aspect and its various possible implementations.

[0041] It should be understood that the beneficial effects of the third to fifth aspects mentioned above can be referred to the description of the first and second aspects mentioned above, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] Illustrative embodiments of the present application include, but are not limited to, a Bluetooth connection method, a readable storage medium, and an electronic device.

[0052] The technical solution of this application is introduced below with reference to the accompanying drawings.

[0053] It should be understood that the Bluetooth device to which the technical solution of this application is applicable can be any electronic device that can establish a communication connection with other electronic devices via Bluetooth, including but not limited to Bluetooth headsets, wearable devices (such as smart watches, smart bracelets, smart glasses, etc.), smart speakers, etc., without limitation here. The following description takes the Bluetooth device as a Bluetooth headset as an example.

[0054] Preemptive connection refers to a connection method in which Bluetooth device C automatically establishes a Bluetooth communication connection with Bluetooth device A upon detecting the last connected Bluetooth device A, regardless of whether Bluetooth device A is connected to other Bluetooth devices. Generally, the preemptive connection function is triggered when a Bluetooth device is started. Therefore, if Bluetooth device A has already established a Bluetooth connection with Bluetooth device B, Bluetooth device C will automatically establish a Bluetooth communication connection with Bluetooth device A when it starts. However, Bluetooth devices can generally only establish a communication connection with one other Bluetooth device at a time. Preemptive connection will cause the Bluetooth communication connection between Bluetooth device A and Bluetooth device B to be automatically disconnected, affecting the user experience.

[0055] After Bluetooth device A, which is connected to Bluetooth device B via Bluetooth communication, is preempted by Bluetooth device C, the user can restart Bluetooth device B to trigger the preemptive connection function of Bluetooth device B, so that Bluetooth device B can reconnect to Bluetooth device A. However, restarting Bluetooth device B is cumbersome and time-consuming, which affects the user experience.

[0056] For example, in the scenario shown in FIG1 , referring to FIG2A , if the Bluetooth headset 20 includes a corresponding earphone case 40, the user must first remove the Bluetooth headset 20 from their ear and place it in the earphone case 40, then remove it from the earphone case 40 and put it on in order to restart the Bluetooth headset 20. However, the steps of first removing the Bluetooth headset 20, placing it in the earphone case 40, then removing it from the earphone case 40 and putting it on are cumbersome and affect the user experience. Furthermore, if the user is driving, removing the Bluetooth headset 20, placing it in the earphone case 40, then removing it from the earphone case 40 and putting it on can also affect driving safety.

[0057] For another example, referring to FIG2B , the Bluetooth headset 50 includes a function key 51. The user can restart the Bluetooth headset 50 by first long pressing the function key 51 to turn off the Bluetooth headset 50, and then long pressing the function key 51 to turn on the Bluetooth headset 50. However, turning off the Bluetooth headset 50 and then turning it back on takes a long time, which affects the user experience.

[0058] In order to improve the user experience of connecting to a Bluetooth device, an embodiment of the present application provides a Bluetooth connection method. The Bluetooth device can first define a reconnection operation for triggering a preemptive connection (for example, a single short press operation, multiple consecutive short press operations, a long press operation on a button on a Bluetooth headset or a headphone box of a Bluetooth headset, an operation by the user to open or close the headphone box, etc.). When the Bluetooth device is in the on state and has not established a Bluetooth communication connection with other Bluetooth devices, if a user's reconnection operation is detected, the preemptive connection is triggered and a communication connection is automatically established with the last connected Bluetooth device. In this way, the user can trigger the preemptive connection function of the Bluetooth device through a reconnection operation without restarting the Bluetooth device. The operation is convenient and conducive to improving the user experience.

[0059] It should be understood that the reconnection operation can be any operation performed by the user on the Bluetooth device or an accessory device of the Bluetooth device, such as a short press or long press of a button on the Bluetooth device or an accessory device of the Bluetooth device, or an operation of moving a component of the Bluetooth device or an accessory device of the Bluetooth device.

[0060] It should be understood that a short press operation refers to an operation in which a user presses a button or sensor and then lifts it after a time shorter than the short press duration. In some embodiments, a short press operation may also be referred to as a single-click operation.

[0061] It should be understood that a long press operation refers to an operation in which a user presses a button or sensor and then lifts it after the long press duration has expired.

[0062] It should be understood that a continuous multiple short press operation refers to a multiple short press operation on a button or sensor by a user within a preset time period. In some embodiments, two consecutive short press operations can also be referred to as a double-click operation.

[0063] It should be understood that the reconnection operation can also be other operations, such as the user's pressing operation on the pressure sensor of the Bluetooth headset or headphone box, the user's touching operation on the proximity light sensor / touch sensor / distance sensor on the Bluetooth headset or headphone box, the user's tapping operation on the vibration sensor on the Bluetooth headset or headphone box, etc.

[0064] For example, referring to Figure 3, for the aforementioned Bluetooth headset 20, the reconnection operation can be a single short press operation, multiple consecutive short press operations or long press operations of the button 41 on the headset box 40, an opening or closing operation of the headset box 40, etc.

[0065] As shown in Figure 3, it is assumed that the mobile phone 10 and the Bluetooth headset 20 establish a Bluetooth communication connection (①) before the car computer 30 is started, and the Bluetooth communication connection of the mobile phone 10 is seized after the car computer 30 is started (②). After the car computer 30 seizes the Bluetooth communication connection of the mobile phone 10, the user can perform the aforementioned reconnection operation on the button 41 or the cover of the headset box 40. When the Bluetooth headset 20 detects the reconnection operation, it triggers the seizure connection in the power-on state and re-establishes the Bluetooth communication connection with the mobile phone 10 (③). In this way, the user can re-establish the Bluetooth communication connection between the Bluetooth headset 20 and the mobile phone 10 through a simple reconnection operation, and resume playing the audio in the mobile phone 10 through the Bluetooth headset 20. The operation is convenient and helps to improve the user experience.

[0066] For another example, for the aforementioned Bluetooth headset 50, the reconnection operation can be a single short press operation or multiple consecutive short press operations by the user on the function key 51.

[0067] Referring to Figure 4, it is assumed that the mobile phone 10 and the Bluetooth headset 50 establish a Bluetooth communication connection (①) before the car computer 30 is started, and the Bluetooth communication connection of the mobile phone 10 is seized after the car computer 30 is started (②). After the car computer 30 seizes the Bluetooth communication connection of the mobile phone 10, the user can perform the aforementioned reconnection operation on the button 51. When the Bluetooth headset 50 detects the reconnection operation, it triggers the preemption connection in the power-on state and re-establishes the Bluetooth communication connection with the mobile phone 10 (③). In this way, after the user seizes the Bluetooth communication connection of the mobile phone 10 on the car computer 30, the preemption connection function of the Bluetooth headset 50 can be triggered by the aforementioned reconnection operation on the function key 51 without restarting the Bluetooth headset 50, which is convenient to operate.

[0068] It should be understood that in other embodiments, the reconnection operation may also be other operations, such as a tapping operation by the user on the Bluetooth headset 20, etc., which is not limited here.

[0069] It should be understood that the method provided in the embodiment of the present application can be applicable to the scenario where the Bluetooth communication connection between the Bluetooth headset and other Bluetooth devices is preempted, and can also be applicable to the scenario where the Bluetooth communication connection between the Bluetooth headset and other Bluetooth devices is disconnected due to other reasons, and is not limited here.

[0070] The following describes the technical solution of the present application in conjunction with the scenarios shown in FIG3 and FIG4 .

[0071] FIG5 is a flow chart showing a method for connecting to Bluetooth according to some embodiments of the present application. As shown in FIG5 , the process includes the following steps:

[0072] S501: A first Bluetooth device establishes a Bluetooth communication connection with a second Bluetooth device.

[0073] If the first Bluetooth device has been connected to the second Bluetooth device in the past, that is, the pairing relationship between the first Bluetooth device and the second Bluetooth device is stored in the first Bluetooth device, the first Bluetooth device can automatically establish a Bluetooth communication connection with the second Bluetooth device when detecting the second Bluetooth device when it is started.

[0074] If the first Bluetooth device has never been connected to the second Bluetooth device, that is, the first Bluetooth device does not store a pairing relationship between the first Bluetooth device and the second Bluetooth device, the first Bluetooth device and the second Bluetooth device may first establish a pairing relationship, and then establish a Bluetooth communication connection with the second Bluetooth device.

[0075] For example, for the situation shown in FIG3 , if the Bluetooth headset 20 (as the first Bluetooth device) has been connected to the mobile phone 10 (as the second electronic device) in the past, the Bluetooth headset 20 can automatically establish a Bluetooth communication connection with the mobile phone 10 when the user opens the headset box 40 .

[0076] For example, for the situation shown in FIG4 , if the Bluetooth headset 50 (as the first Bluetooth device) has been connected to the mobile phone 10 (as the second electronic device) in the past, the Bluetooth headset 50 can automatically establish a Bluetooth communication connection with the mobile phone 10 when it is turned on.

[0077] It should be understood that the embodiments of the present application do not limit the manner in which the first Bluetooth device and the second Bluetooth device establish a Bluetooth communication connection.

[0078] S502: When the first Bluetooth device is powered on, it detects that the Bluetooth communication connection with the second Bluetooth device is disconnected.

[0079] When the first Bluetooth device is powered on, it detects that the Bluetooth communication connection with the second Bluetooth device is disconnected, triggering the Bluetooth connection method provided in the embodiment of the present application.

[0080] For example, in the scenario shown in FIG3 , after the vehicle computer 30 starts and seizes the mobile phone 10 , the Bluetooth headset 20 (as the first Bluetooth device) can detect that the Bluetooth communication connection with the mobile phone 10 is disconnected.

[0081] For another example, in the scenario shown in FIG. 4 , after the vehicle computer 30 starts and seizes the mobile phone 10 , the Bluetooth headset 50 (as the first Bluetooth device) can detect that the Bluetooth communication connection with the mobile phone 10 is disconnected.

[0082] S503: The first Bluetooth device determines whether a reconnection operation is detected.

[0083] After detecting that the Bluetooth communication connection with the second Bluetooth device is disconnected, the first Bluetooth device determines whether a reconnection operation is detected. If a reconnection operation is detected, it indicates that the user desires to reestablish the Bluetooth communication connection between the first Bluetooth device and the second Bluetooth device, and the process proceeds to step S504. Otherwise, if no reconnection operation is detected, the process proceeds to step S505.

[0084] It should be understood that the reconnection operation may be any operation performed by the user on the first Bluetooth device or on an accessory device of the first Bluetooth device.

[0085] For example, for the Bluetooth headset 20 shown in Figure 3, the reconnection operation can be a single short press operation of the button 41 on the earphone box 40, multiple consecutive short press operations or a long press operation (for example, a long press for a preset time), an opening or closing operation of the earphone box 40, or a tapping operation, a touch operation, or a pressing operation of the user on the sensor on the Bluetooth headset 20, etc.

[0086] For another example, for the Bluetooth headset 50 shown in FIG4 , the reconnection operation may be a single or multiple consecutive short press operations on the function key 51 by the user.

[0087] It should be understood that in the scenario shown in FIG3 , the earphone box 40 can communicate with the Bluetooth headset 20 via Bluetooth, wireless fidelity (Wi-Fi), infrared, near-field communication, etc., and upon detecting a reconnection operation by the user on the earphone box, the earphone box 40 sends a reconnection message to the Bluetooth headset 20. Upon receiving the reconnection message, the Bluetooth headset 20 detects the reconnection operation.

[0088] For example, referring to Figure 6, the earphone box 40 can send a reconnection message to the Bluetooth headset 20 when it detects a single short press operation, multiple consecutive short press operations, or a long press operation of the button 41 by the user, or detects that the user opens or closes the cover of the earphone box 40, so that the Bluetooth headset 20 (as the first Bluetooth device) can detect the reconnection operation.

[0089] It should be understood that in other embodiments, the earphone box 40 may not send a reconnection message indicating the user's reconnection operation on the earphone box 40 to the Bluetooth headset 20, but instead send a reconnection instruction to the Bluetooth headset 20 when a reconnection operation is detected. In this way, when the Bluetooth headset 20 receives the reconnection instruction, it can respond to the reconnection instruction and re-establish the Bluetooth communication connection with the last connected Bluetooth device.

[0090] S504: The first Bluetooth device triggers a connection preemption function to re-establish a Bluetooth communication connection with the second Bluetooth device.

[0091] After detecting the reconnection operation, the first Bluetooth device triggers the preemptive connection function and re-establishes the Bluetooth communication connection with the last connected Bluetooth device (ie, the second Bluetooth device).

[0092] For example, for the situation shown in Figure 3, after the user seizes the Bluetooth communication connection of the mobile phone 10 on the car computer 30, the Bluetooth headset 20 can trigger the connection seizure function of the Bluetooth headset 20 when it receives a single short press operation, multiple consecutive short press operations or a long press operation on the button 41 sent by the earphone box 40, or receives an operation of the user turning on or off the earphone box 40 sent by the earphone box 40, and detects a tapping operation, a touch operation or a pressing operation on the sensor on the user's Bluetooth headset 20, so that the Bluetooth headset 20 re-establishes the Bluetooth communication connection with the mobile phone 10.

[0093] For example, for the situation shown in Figure 4, after the user seizes the Bluetooth communication connection of the mobile phone 10 on the car computer 30, the Bluetooth headset 50 can trigger the preemptive connection function of the Bluetooth headset 50 when detecting the user's aforementioned reconnection operation on the function key 51, so that the Bluetooth headset 50 re-establishes the Bluetooth communication connection with the mobile phone 10.

[0094] It should be understood that in some embodiments, the first Bluetooth device triggers the connection preemption function and re-establishes the Bluetooth communication connection with the second Bluetooth device only when it is not currently connected to other Bluetooth devices.

[0095] It should be understood that in some embodiments, if the first Bluetooth device does not detect the last connected Bluetooth device (the second Bluetooth device) when triggering the preemptive connection function, the first Bluetooth device can select a Bluetooth device that was most recently connected to the first Bluetooth device from the detectable Bluetooth devices that have historically connected to the first Bluetooth device, and establish a Bluetooth communication connection with the Bluetooth device.

[0096] It should be understood that in some embodiments, after detecting a reconnection operation, the first Bluetooth device may also play a prompt message to inform the user that the preemptive connection function is about to be triggered and that the user can perform a cancellation operation (as a first operation) or a confirmation operation (as a second operation). The first Bluetooth device can re-establish a Bluetooth communication connection with the second Bluetooth device when the user's confirmation operation is detected or when the user's cancellation operation is not detected. In this way, the reconnection of the first and second Bluetooth devices due to user error can be avoided, which is conducive to improving the user experience.

[0097] For example, in the scenario shown in FIG3 , the Bluetooth headset 20 may play a prompt tone, “About to reconnect to mobile phone 10. To cancel the reconnection, press the function key on the headset box.” If the Bluetooth headset 20 detects that the user presses button 41 (cancel operation), the Bluetooth communication connection with the second Bluetooth device is canceled. Otherwise, the Bluetooth communication connection with the second Bluetooth device is re-established.

[0098] For another example, in the scenario shown in FIG4 , the Bluetooth headset 50 may play a prompt tone, “About to reconnect to mobile phone 10, please press the function key to confirm the reconnection,” upon detecting a reconnection operation. If the Bluetooth headset 50 detects that the user presses button 51 (confirmation operation), it re-establishes the Bluetooth communication connection with the second Bluetooth device; otherwise, it cancels the Bluetooth communication connection with the second Bluetooth device.

[0099] It should be understood that the cancel operation or confirmation operation can be any operation performed by the user on the first Bluetooth device or the accessory device of the first Bluetooth device. For example, the cancel operation or confirmation operation can be any of the aforementioned reconnection operations, which is not limited here.

[0100] S505: The first Bluetooth device determines whether the time period for not being connected to the Bluetooth device reaches a first time period.

[0101] When the first Bluetooth device does not detect a reconnection operation, it determines whether the time period during which the first Bluetooth device has not been connected to the Bluetooth device has reached a first time period. If it is determined that the time period during which the first Bluetooth device has not been connected to the Bluetooth device has reached the first time period, it indicates that the user will not use the Bluetooth headset for the time being, and the process proceeds to step S506. Otherwise, if it is determined that the time period during which the first Bluetooth device has not been connected to the Bluetooth device has not reached the first time period, the process proceeds to step S503 to continue determining whether a reconnection operation has been detected.

[0102] S506: The first Bluetooth device is powered off.

[0103] The first Bluetooth device turns off the first Bluetooth device when the time period during which the first Bluetooth device is not connected to the Bluetooth device reaches a first time period, thereby reducing the power consumption of the first Bluetooth device.

[0104] Through the method provided in the embodiments of the present application, after a second Bluetooth device connected to a first Bluetooth device is preempted, a user can trigger the first Bluetooth device to reestablish a Bluetooth communication connection with the second Bluetooth device by performing a reconnection operation on the first Bluetooth device or an accessory device of the first Bluetooth device.

[0108] The memory 202 may be used to store instructions or data program codes, such as instructions or program codes corresponding to the aforementioned Bluetooth connection method.

[0109] The processor 201 can be used to execute the above-mentioned application code and call related modules to implement different functions.

In some embodiments, the wireless communication module 203 can be a Bluetooth chip. The Bluetooth headset 20 can be paired with the Bluetooth chip of other electronic devices through the Bluetooth chip and establish a Bluetooth communication connection to achieve wireless communication between the Bluetooth headset 20 and other electronic devices through the wireless connection.

[0112] In addition, the wireless communication module 203 may also include an antenna. The wireless communication module 203 receives electromagnetic waves via the antenna, frequency-modulates and filters the electromagnetic wave signals, and transmits the processed signals to the processor 201. The wireless communication module 203 may also receive signals to be transmitted from the processor 201, frequency-modulate and amplify the signals, and convert them into electromagnetic waves for radiation via the antenna.

[0113] In some embodiments, the Bluetooth headset 20 can receive a reconnection operation sent by the headset box 40 through the wireless communication module 203 .

[0114] The audio module 204 can be used to manage audio data and enable the input and output of audio signals to the Bluetooth headset 20. For example, the audio module 204 can obtain audio signals from the wireless communication module 203 or transmit audio signals to the wireless communication module 203, enabling functions such as making and receiving calls, playing music, activating / deactivating the voice assistant of the electronic device connected to the headset, and receiving / sending the user's voice data through the wireless headset.

[0115] The audio module 204 may include a speaker (or earpiece, receiver) component for outputting audio signals, a microphone (or microphone, sound source), and a microphone receiving circuit that cooperates with the microphone. The speaker can be used to convert audio electrical signals into sound signals and play them. The microphone can be used to convert audio signals into electrical signals. The audio module 204 (e.g., speaker, also known as "speaker") includes a magnet (e.g., a magnet).

[0116] The power module 205 can be used to provide system power to the Bluetooth headset 20, powering each module of the Bluetooth headset 20; and supporting the Bluetooth headset 20 in receiving charging input. The power module 205 may include a power management unit (PMU) and a battery (i.e., a first battery). The power management unit may include a charging circuit, a voltage drop regulation circuit, a protection circuit, a power measurement circuit, etc. The charging circuit may receive external charging input.

[0117] The sensor module 206 may include a distance sensor and / or a proximity light sensor, a touch sensor, a bone conduction sensor, a pressure sensor, a vibration sensor, and the like.

[0118] The distance sensor / proximity light sensor / pressure sensor can be used to detect whether the user is wearing the Bluetooth headset 20. For example, the processor 201 can determine whether the user is wearing the Bluetooth headset 20 based on data collected by the distance sensor or the proximity light sensor.

[0119] In some embodiments, the distance sensor / proximity light sensor / pressure sensor may also be used to detect a user's reconnection operation. For example, when the distance between the user and the distance sensor / proximity light sensor is less than a preset distance, or when the user presses the pressure on the pressure sensor with a pressure greater than a preset pressure, the processor 201 may detect a reconnection operation.

[0120] The data collected by the vibration sensor can be used to detect the user's operation on the Bluetooth headset 20, such as a tapping operation, etc. The processor 201 can trigger a corresponding function according to the user's operation.

[0121] For example, in some embodiments, the Bluetooth headset 20 may define a user's operation on the vibration sensor, such as a tapping operation, as a reconnection operation. Thus, upon detecting the user's reconnection operation, the processor 201 may trigger a preemptive connection function, so that the Bluetooth headset 20 establishes a Bluetooth communication connection with the last connected Bluetooth device.

[0122] The data collected by the touch sensor can be used to detect the user's operation on the Bluetooth headset 20, such as a touch operation, a tapping operation, etc. The processor 201 can trigger a corresponding function according to the user's operation.

[0123] For example, in some embodiments, the Bluetooth headset 20 may define a user operation on the touch sensor, such as a touch operation or a tap operation, as a reconnection operation. Thus, upon detecting the user's reconnection operation, the processor 201 may trigger a preemptive connection function, so that the Bluetooth headset 20 establishes a Bluetooth communication connection with the last connected Bluetooth device.

[0124] The sensor module 206 may further include a magnetic sensor for detecting the magnetic induction intensity around the Bluetooth headset 20. When the Bluetooth headset 20 is placed in the receiving compartment of the headset box 40, the Bluetooth headset 20 can be turned on or off according to the magnetic field intensity detected by the magnetic sensor.

[0125] The button 207 may include at least one button, such as a volume adjustment button or a function button, and the button 207 may be a mechanical button or a touch button. The Bluetooth headset 20 may define the user's operation on the button as a reconnection operation and establish a Bluetooth communication connection with the last connected Bluetooth device when the reconnection operation is detected.

[0126] It should be understood that in some embodiments, the Bluetooth headset 20 may further include an input and output interface for establishing a wired communication connection with other electronic devices or receiving power from other electronic devices and charging the battery.

[0127] It should be understood that for the aforementioned Bluetooth headset 20, since the left earphone and the right earphone are physically separated, both the left earphone and the right earphone can include a processor 201, a memory 202, a wireless communication module 203, an audio module 204, a power module 205, a sensor module 206, and a button 207.

[0128] It should be understood that the structure of the Bluetooth headset 20 shown in FIG7 is only an example. In other embodiments, the Bluetooth headset 20 may include more or fewer modules, or some modules may be split or combined, which is not limited here.

[0129] It should be understood that the structure of the Bluetooth headset 50 can be the same as or different from that of the Bluetooth headset 20, and this is not limited here. It should be understood that for the aforementioned Bluetooth headset 50, since the left and right earphones of the Bluetooth headset 50 are not physically separated, the Bluetooth headset 50 can only include a set of processor 201, memory 202, wireless communication module 203, audio module 204, power module 205, sensor module 206, and button 207.

[0130] Furthermore, FIG8 shows a schematic structural diagram of an earphone box 40 according to some embodiments of the present application.

[0131] As shown in FIG8 , the earphone box 40 may include a processor 401 , a memory 402 , a wireless communication module 403 , an input / output interface 404 , a power module 405 , a sensor module 406 , a button 41 , and the like.

[0132] The processor 401 may include one or more interfaces for connecting to other modules of the earphone box 40 .

[0133] Among them, the memory 402 can be used to store instructions or program codes, such as instructions or program codes for detecting reconnection operations and sending reconnection operations to the Bluetooth headset 20, codes for charging the Bluetooth headset 20 when the Bluetooth headset 20 is placed in the headset box 40, etc.

[0134] The processor 401 can be used to execute the above-mentioned application code and call related modules to implement different functions. For example, it can implement the charging function of the earphone box 40, as well as the detection function of the earphone box switch cover, the detection function of the reconnection operation, etc. The processor 401 may include one or more processing units. Different processing units may be independent devices or integrated into one or more processors 401. The processor 401 may specifically be an integrated control chip, or it may be composed of a circuit including various active and / or passive components, and the circuit is configured to perform the functions belonging to the processor 401 described in the embodiments of the present application.

[0135] The sensor module 406 may include a first pressure sensor. The processor 401 may determine whether the earphone box 40 is open based on the data collected by the first pressure sensor. For example, when the earphone box 40 is in a closed state, the impedance detected by the first pressure sensor is a first impedance, and a first signal is output to the processor 401. When the earphone box is in an open state, the impedance detected by the first pressure sensor is a second impedance, and a second signal is output to the processor 401, wherein the first signal is a high level and the second signal is a low level, or the first signal is a low level and the second signal is a high level. The processor 401 determines that the earphone box 40 is open in response to the signal transmitted by the first pressure sensor changing from the first signal to the second signal, and determines that the earphone box 40 is closed in response to the signal transmitted by the first pressure sensor changing from the second signal to the first signal.

[0136] In some embodiments, when there is at most one earphone in the earphone box 40 (for example, the left earphone or the right earphone of the Bluetooth earphone 20), the user's operation of opening and / or closing the lid of the earphone box can be defined as a reconnection operation. After detecting the user's operation of opening and / or closing the lid, the processor 401 can send a reconnection message corresponding to the reconnection operation to the Bluetooth earphone 20 through the wireless communication module 403.

[0137] The sensor module 406 may also include a second pressure sensor. The processor 401 can determine whether the Bluetooth headset 20 has left the headset case based on data collected by the second pressure sensor. For example, the second pressure sensor is located at the bottom of the left or right storage compartment. When the left earphone of the Bluetooth headset 20 is in the storage compartment, the second pressure sensor detects a third impedance and outputs a third signal to the processor 401. When the right earphone of the Bluetooth headset 20 is in the storage compartment, the second pressure sensor detects a fourth impedance and outputs a fourth signal to the processor 401. When the left earphone of the Bluetooth headset 20 is not in the storage compartment, the second pressure sensor detects a fifth impedance and outputs a fifth signal to the processor. When the right earphone of the Bluetooth headset 20 is not in the storage compartment, the second pressure sensor detects a sixth impedance and outputs a sixth signal to the processor. The third and fourth signals are high, and the fifth and sixth signals are low. In response to the signal transmitted by the second pressure sensor changing from the third and fourth signals to the fifth and sixth signals, the processor 401 determines that both left and right wireless earphones have left the headset case 40.

[0138] It should be understood that the sensor module 406 can also be used to detect the user's reconnection operation, so that the processor 401 can send a reconnection message or reconnection instruction to the Bluetooth headset when the reconnection operation is detected. For details, please refer to the description of the sensor module 206 above, which will not be repeated here.

[0139] The wireless communication module 403 can be used to support data exchange between the earphone box 40 and other electronic devices or the Bluetooth headset 20, including wireless communication such as Bluetooth, global navigation satellite system, wireless local area network (WLAN), such as Wi-Fi network, frequency modulation, short-range wireless communication technology, infrared technology, etc. In some embodiments, the wireless communication module 403 can be a Bluetooth chip.

[0140] In addition, the wireless communication module 403 may also include an antenna. The wireless communication module 403 receives electromagnetic waves via the antenna, frequency-modulates and filters the electromagnetic wave signals, and transmits the processed signals to the processor 401. The wireless communication module 403 may also receive a signal to be transmitted from the processor 401, frequency-modulate it, amplify it, and convert it into electromagnetic waves for radiation via the antenna.

[0141] In some embodiments, the wireless communication module 403 may be configured to send a reconnection message corresponding to the reconnection operation to the Bluetooth headset 20 .

[0142] The input / output interface 404 is used to establish a wired communication connection with other electronic devices or to receive power from other electronic devices and charge the battery.

[0143] The button 41 is used to trigger the function of the earphone box 40 or the Bluetooth headset 20, such as triggering the pairing function of the Bluetooth headset 20. The button 41 can be a physical button or a touch button, and the form of the button 41 is not limited here.

[0144] In some embodiments, the user's operation on the button 41 can be defined as a reconnection operation. After detecting the user's reconnection operation on the button 41, the processor 401 can send a reconnection message corresponding to the reconnection operation to the Bluetooth headset 20.

[0145] It should be understood that in some embodiments, the earphone box 40 may further include an indicator light, which may be used to indicate the status of the earphone box 40 or the Bluetooth headset 20. For example, the indicator light may indicate the battery level in the earphone box, whether the Bluetooth headset 20 is in a pairing state, etc., by using different colors or flashing frequencies.
