[0004] In TWS (True Wireless Stereo) application scenarios, it is necessary to reconnect immediately after the headphone box lid is opened, but LE devices do not have the reconnection function and can only passively accept connections. In addition, since the LE Audio connection method cannot clearly identify the target device to be connected, it may cause the Bluetooth headset to be connected incorrectly, and the left and right ears of the same pair of Bluetooth headsets may be connected to different devices.

When implementing the step, those skilled in the art may execute S2 first and then S1, etc., but these should all be within the scope of protection of this application.

[0051] It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0052] In the subsequent description, the use of suffixes such as "module", "component" or "unit" to represent elements is only for the purpose of facilitating the description of the present application and has no specific meaning. Therefore, "module", "component" or "unit" can be used interchangeably.

[0053] With the advent of LE Audio technology, which transmits audio data over a Bluetooth low energy connection, Bluetooth products achieve low power consumption and low latency. However, true wireless stereo applications require the earphone box to reconnect immediately upon opening, but LE devices lack this functionality and can only accept connections. While the LE Audio protocol is considering allowing LE peripheral devices to initiate connections, this requires ensuring that the phone is constantly scanning for broadcasts, which relies on the phone's implementation. Furthermore, because LE Audio's connection method doesn't explicitly specify the target device to connect to, it can lead to issues like misconnecting Bluetooth headsets and connecting the left and right earbuds of the same pair to different devices. For example, if a pair of Bluetooth headsets has previously been connected to device A, which may be constantly scanning for the pair, and now needs to pair with a new device B, when both earbuds broadcast non-directionally, device A may connect, preventing the intended device B from connecting. Alternatively, the left earbud may connect to device B while the right earbud is connected to device A, resulting in a poor user experience.

[0054] In order to solve the above problems, this application proposes a Bluetooth connection method, device, computer equipment and readable storage medium, which realizes the automatic connection of Bluetooth low energy consumption of Bluetooth headsets with the target terminal through cross-transmission key derivation, solves the problems of misconnection and mixed connection of Bluetooth headsets in the current LE Audio technology, and completes the transition between ordinary Bluetooth products to low-power audio products, improving user experience while reducing the required transition costs.

[0055] See also Figure 1 , Figure 1 : is a flowchart of the Bluetooth connection method provided in an embodiment of the present application. The Bluetooth connection method may specifically include:

[0056] S1. Establish a first connection between a master headset and a slave headset of a Bluetooth headset pair.

[0057] Specifically, for step S1, it is first necessary to establish a first connection between the master earphone and the slave earphone in the Bluetooth earphone pair, where the first connection is a TWS (True Wireless Stereo) connection, including a BT (Bluetooth) connection and / or a BLE (Bluetooth Low Energy) connection.

[0058] S2. After the Bluetooth headset enters pairing mode, the first mode and the second mode of the master headset are turned on, so that after the Bluetooth headset receives a connection request initiated by the terminal, a second connection between the master headset and the terminal is established.

[0059] Specifically, in step S2, in order for the Bluetooth headset pair to connect to the new terminal device, when the Bluetooth headset pair enters pairing mode, the master headset in the Bluetooth headset pair opens a first mode and a second mode, where the first mode can be an inquiry scan mode (discoverable mode) and the second mode can be a page scan mode (connectable mode). After the user clicks connect, the Bluetooth headset receives the connection request initiated by the terminal, thereby establishing a second connection between the master headset and the terminal, where the second connection is a classic Bluetooth connection.

[0060] S3. According to the second connection, the Bluetooth device address resolution key and the device unique address information of the terminal are sent to the master headset, so that the master headset performs a directional broadcast with the terminal according to the Bluetooth device address resolution key and the device unique address information.

[0061] Specifically, for step S3, based on the second connection established between the main headset and the terminal, the terminal's IRK (The Identity Resolving Key) Bluetooth device address resolution key and IA (Identify Address) device unique address information are sent to the main headset, so that the main headset calculates the random address of the remote device based on the received device address resolution key and device unique address information, and receives the connection of the terminal device through directional broadcast.

[0062] Optionally, in some embodiments, the master headset performs directional broadcasting with the terminal based on the Bluetooth device address resolution key and the device unique address information, which may specifically include:

[0063] Add the terminal's Bluetooth device address resolution key and device unique address information to the broadcast device filter list through the main headset;

[0064] After the terminal's Bluetooth device address resolution key and device unique address information are sent to the Bluetooth controller's resolvable list through the host control layer of the main headset, the Bluetooth controller calculates the random address of the terminal device as the target address of the directional broadcast, and starts the directional broadcast of the main headset.

[0065] Specifically, after the terminal's Bluetooth device address resolution key and device unique address information are sent to the master headset based on the second connection, the terminal's Bluetooth device address resolution key and device unique address information are obtained using the SMP secure connection process, and the LE Add Device To Resolving List command is sent to the Bluetooth controller through the Host control layer on the master headset to generate a random address for the terminal device. At the same time, the terminal's device unique address information is used as the target address for directional broadcasting, and the master headset's directional broadcast is started, so that the master headset conducts directional broadcasting with the terminal based on the newly added broadcast list, and waits for the terminal to connect based on the master headset's device unique address information before broadcasting. Alternatively, a device filter list request is sent to the Bluetooth controller through the Host control layer on the master headset to generate a device filter list. The master headset starts non-directional broadcasting based on the device filter list, thereby filtering out terminals that are not in the device filter list to avoid misconnection.

[0066] It should be noted that non-directional broadcasting can also be used between the main headset and the terminal. The main headset uses the terminal's Bluetooth device address resolution key and device unique address information as device filter list information to filter the received connection requests.

[0067] Optionally, in some embodiments, after establishing the second connection between the primary headset and the terminal, the Bluetooth connection method may further include:

[0068] Acquiring connection event information according to the second connection;

[0069] Determine whether the terminal supports low-power audio technology based on the device type information in the connection event information.

[0070] Specifically, after establishing the second connection between the main headset and the terminal, this embodiment also provides for identifying the device type of the terminal. Since Bluetooth will identify the device information in the connection event during the connection process, for example, the device type information of the terminal will be reported in the connection event information. By judging the device type information, you can know whether the current terminal supports LE Audio low-power audio technology. If not, the entire Bluetooth connection process ends, and it is determined that the current terminal does not support LE Audio low-power audio technology, and there is no need to send LE Audio broadcasts. Only after determining that the terminal supports LE Audio low-power audio technology, will the subsequent process continue. Since LE Audio technology is still in the popularization stage, most mobile phones on the market may not support LE Audio. Then when the headset recognizes that the mobile phone does not support LE Audio, it can reduce unnecessary interactions, such as broadcasting waiting for connection, to achieve the problem of reducing power consumption.

[0071] Optionally, in some embodiments, sending the Bluetooth device address resolution key and device unique address information of the terminal to the primary headset according to the second connection may specifically include:

[0072] After the terminal is connected to the main headset according to the second connection, the terminal initiates a secure connection process on the channel corresponding to the second connection, and calculates the long-term connection key corresponding to the low-power Bluetooth connection from the traditional Bluetooth connection key of the second connection.

[0073] Specifically, after the main headset establishes a second connection with the terminal, the terminal first connects to the main headset according to the established second connection, and then initiates the SMP (secure connection) process in the channel corresponding to the second connection (for example, L2CAP Channel) through the terminal. The LTK (LongTime Key) is calculated and derived from the Link Key connection key of the channel corresponding to the second connection, that is, the long-term key used to create session keys and encrypt messages at the link layer.

[0074] It should be noted that this embodiment calculates the long-term connection key corresponding to the BLE connection from the BT connection key of the second connection, so that the next time the terminal is connected, the BLE connection with the terminal can be established directly based on the long-term connection key, without the need to calculate the BLE LTK (long-term key) separately, thereby effectively improving the efficiency of Bluetooth directional connection.

[0075] Optionally, in some embodiments, after the terminal initiates a secure connection process in the channel corresponding to the second connection, the following steps may be specifically included:

[0076] Obtain the terminal's Bluetooth device address resolution key and device unique address information; the device unique address information includes the device unique address and its address type information.

[0077] Specifically, after the terminal initiates the SMP (secure connection) process in the channel corresponding to the second connection, the Bluetooth device address resolution key and device unique address information corresponding to the terminal will also be obtained; the device unique address information includes the device unique address and its address type information.

[0078] S4. According to the first connection, the master headset sends the Bluetooth device address resolution key and the device unique address information to the slave headset through the directional broadcast, so that the slave headset performs non-directional broadcasting with the terminal based on the Bluetooth device address resolution key and the device unique address information.

[0079] Specifically, for step S4, according to the first connection established between the master earphone and the slave earphone, after the master earphone completes the directional broadcast, the Bluetooth device address resolution key and the device unique address information of the terminal are sent to the slave earphone through the master earphone, so that the slave earphone uses non-directional broadcast according to the Bluetooth device address resolution key and the device unique address information of the terminal, and filters the devices requesting connection at the same time.

[0080] Optionally, in some embodiments, the headset performs non-directional broadcasting with the terminal based on the Bluetooth device address resolution key and the device unique address information, which may specifically include:

[0081] by adding the Bluetooth device address resolution key and the device unique address information received according to the first connection to the device filtering list from the headset;

[0082] After the device filter list is sent to the Bluetooth controller through the host control layer of the slave headset, the non-directional broadcast of the slave headset is started, so that the slave headset filters the connection request according to the device filter list.

[0083] Specifically, since the slave earphone does not have the Bluetooth device address resolution key of the terminal in advance, it is necessary to send the Bluetooth device address resolution key and device unique address information of the terminal device to the slave earphone through the master earphone according to the first connection. After receiving the Bluetooth device address resolution key and device unique address information, the slave earphone is added to the device filter list, so as to generate a device filter list by sending a request to add the device filter list to the Bluetooth main controller through the Host control layer of the slave earphone. At the same time, the slave earphone filters the received connection requests according to the device filter list, and finally ensures that the master earphone and the slave earphone can connect to the same device, avoiding the situation where the master earphone cannot reconnect or mixed connections occur.

[0084] Alternatively, as Figure 2 As shown, in some embodiments, the Bluetooth connection method may further include:

[0085] S5. After completing the directional broadcast between the master headset and the terminal, and the non-directional broadcast between the slave headset and the terminal, a third connection between the Bluetooth headset pair and the terminal is established.

[0086] After completing the directional broadcast between the master headset and the terminal, and completing the non-directional broadcast between the slave headset and the same terminal, the third connection between the Bluetooth headset and the terminal is established, where the third connection is a BLE connection. The subsequent Bluetooth headset pair can connect to the terminal according to the third connection when it is turned on and reconnected. Figure 3As shown, in this embodiment, the connection between the master headset and the slave headset is TWS Link (true wireless stereo connection), the connection between the master headset and the terminal includes BTACL (classic Bluetooth connection) and BLE ACL (low-power Bluetooth connection), and the connection between the slave headset and the terminal includes SnoopLink (monitoring connection) and BLE ACL (low-power Bluetooth connection).

[0087] like Figure 4 As shown, the embodiment of the present application also provides a third implementation method, the specific steps include: establishing a Bluetooth (BT) / low-power Bluetooth (BLE) connection between the master headset and the slave headset, the master headset turns on the inquiry scan mode (discoverable mode) and page scan mode (connectable mode), the terminal initiates a classic Bluetooth connection with the master headset, after the classic Bluetooth connection is successfully established, the terminal sends the Bluetooth device address resolution key (IRK) and the device unique address information to the master headset, the master headset turns on the directional broadcast according to the terminal Bluetooth device address resolution key, the device unique address information and its type, and the master headset Bluetooth device address resolution key in the newly added broadcast list, and after the master headset obtains the IRK and address information of the remote device, it is added to the RPA of the Bluetooth controller. In the resolvable list, the terminal random address calculated by the Bluetooth controller is used as the target address of the directed broadcast. After completing the directed broadcast, the master headset sends the terminal Bluetooth device address resolution key, the device unique address information and its type to the slave headset, generates a new list of broadcast addresses and a list of broadcast address receivers, and sends the device filter list and remote device information to the Bluetooth controller through the host control layer of the slave headset, so that after the general broadcast is turned on, the Bluetooth controller filters the connection requests of other devices according to the device filter list and remote device information.

[0088] As can be seen from the above, the Bluetooth connection method provided in the embodiment of the present application includes: establishing a first connection between a master headset and a slave headset of a Bluetooth headset pair; after the Bluetooth headset pair enters pairing mode, turning on the first mode and the second mode of the master headset, so that after the Bluetooth headset receives a connection request initiated by the terminal, a second connection between the master headset and the terminal is established; according to the second connection, the Bluetooth device address resolution key and the device unique address information of the terminal are sent to the master headset, so that the master headset performs a directed broadcast with the terminal based on the Bluetooth device address resolution key and the device unique address information; according to the first connection, the master headset after the directed broadcast sends the Bluetooth device address resolution key and the device unique address information to the slave headset, so that the slave headset performs a non-directional broadcast with the terminal based on the Bluetooth device address resolution key and the device unique address information. An embodiment of the present application proposes a Bluetooth connection method. After the master headset conducts a directional broadcast with the target terminal, the master headset sends the Bluetooth device address resolution key and device unique address information of the target terminal to the slave headset, so that the slave headset completes the non-directional broadcast with the target terminal, and realizes the automatic connection of the Bluetooth low energy of the Bluetooth headset with the target terminal by cross-transmission key derivation, thereby solving the problems of Bluetooth headset misconnection and mixed connection in the current LE Audio technology, and completing the transition between ordinary Bluetooth products and low-power audio products, thereby improving user experience while reducing the required transition cost.

[0089] Correspondingly, this application also provides a Bluetooth connection device, please refer to Figure 5 , Figure 5 It is a structural diagram of the image matching device provided in this application, which may specifically include a first connection module 100, a second connection module 200, a master ear broadcast module 300 and a slave ear broadcast module 400.

[0090] The first connection module 100 is used to establish a first connection between a master earphone and a slave earphone of a Bluetooth earphone pair.

[0091] Specifically, for the first connection module 100, it is first necessary to establish a first connection between the master earphone and the slave earphone in the Bluetooth earphone pair, where the first connection is a TWS (True Wireless Stereo) connection, including a BT (Bluetooth) connection and / or a BLE (Bluetooth Low Energy) connection.

[0092] The second connection module 200 is used to enable the first mode and the second mode of the master headset after the Bluetooth headset enters the pairing mode, so that after the Bluetooth headset receives the connection request initiated by the terminal, a second connection between the master headset and the terminal is established.

[0093] Specifically, for the second connection module 200, in order for the Bluetooth headset pair to connect to a new terminal device, when the Bluetooth headset pair enters pairing mode, the master headset in the Bluetooth headset pair opens the first mode and the second mode, where the first mode can be the inquiry scan mode (discoverable mode) and the second mode can be the page scan mode (connectable mode). After the user clicks on the connection, the Bluetooth headset receives the connection request initiated by the terminal, thereby establishing a second connection between the master headset and the terminal, where the second connection is a classic Bluetooth connection.

[0094] The master ear broadcast module 300 is used to send the Bluetooth device address resolution key and device unique address information of the terminal to the master earphone according to the second connection, so that the master earphone can perform directional broadcasting between the terminal and the terminal according to the Bluetooth device address resolution key and device unique address information.

[0095] Specifically, for the master ear broadcast module 300, according to the second connection established between the master earphone and the terminal, the terminal's IRK (The Identity Resolving Key) Bluetooth device address resolution key and IA (Identify Address) device unique address information are sent to the master earphone, so that the master earphone starts a directional broadcast between the terminal based on the received device address resolution key and device unique address information.
