A detailed description will be given below in conjunction with the accompanying drawings.

Please refer to FIG. 1 . FIG. 1 is a schematic diagram of an application scenario of the Bluetooth connection method disclosed in the embodiment of the present application. As shown in Figure 1, the application scenario may include a headset device 10 and an electronic device 20, wherein the headset device 10 may include a first headset 11 and a second headset 12, and the first headset 11 and the second headset 12 may be arranged in pairs (e.g. left earphone and right earphone respectively). When the earphone device 10 is connected to the electronic device 20 for the first time, it is usually necessary to pair the earphone device 10 with the electronic device 20 to establish a Bluetooth connection between the two. On this basis, when the earphone device 10 is used again subsequently, the earphone device 10 can automatically establish a bluetooth connection with the electronic device 20 according to the address information of the electronic device 20 recorded when the electronic device 20 was connected last time (i.e. "connect back"), so that there is no need to re-pair the process.

It should be noted that the connection back may refer to an operation in which the first electronic device attempts to reconnect with the previously paired and connected second electronic device by means of paging. Specifically, the first electronic device can send a page packet (a Bluetooth connection request) to the second electronic device, and the page packet can be used to connect or activate the second electronic device, so that the first electronic device can establish a connection with the second electronic device. A communication link between electronic devices. Wherein, the above page packet may contain Bluetooth address information of the second electronic device, so that the second electronic device may be paged directly.

Specifically, the earphone device 10 includes the first earphone 11 and the second earphone 12, one of which can be used as a master earphone, and the other can be used as a slave earphone. It should be noted that the master earphone can be used for data transmission based on the bluetooth connection with the electronic device 20 established with it, and at the same time, the master earphone can also synchronize the above bluetooth connection information to the slave earphone, so that the slave earphone can monitor the master earphone Data transmission with the electronic device 20, so that the audio data synchronization between the master earphone and the slave earphone can be realized.

Exemplarily, as shown in FIG. 1 , the first earphone 11 can be used as a master earphone and directly connected to the electronic device 20 ; while the second earphone 12 can be used as a slave earphone and connected to the first earphone 11 as a master earphone. In the process of actually using the earphone device 10, the master-slave relationship between the first earphone 11 and the second earphone 12 can be switched at any time according to scene changes and/or user settings, that is, the first earphone 11 can also be used as a slave earphone, and at the same time The second earphone 12 is used as the main earphone. Optionally, the first earphone 11 and the second earphone 12 may not distinguish the master-slave relationship, that is, the electronic device 20 may establish a Bluetooth connection with the first earphone 11 and the second earphone 12 respectively at the same time. Optionally, the above-mentioned bluetooth connection can be realized based on the classic bluetooth protocol (such as bluetooth 4.0 and other versions formulated by the bluetooth technology alliance bluetooth SIG), and can also be based on the bluetooth low energy (bluetooth low energy, BLE) protocol (for example Bluetooth 5.0 and other versions of the protocol), which are not specifically limited in this embodiment of the present application.

In the embodiment of the present application, when the first earphone 11 is in the connection back state, the first earphone 11 can first determine its own master-slave attribute, where the master-slave attribute can be used to indicate that the first earphone 11 is connected to The master-slave relationship between the second earphones 12 (that is, the first earphone 11 acts as the master earphone or the slave earphone). Further, according to the above-mentioned master-slave attribute, the first earphone 11 can determine the first target device to be connected back to, and the first target device can include the second earphone 12 mentioned above, or a device that has established a Bluetooth connection with the first earphone 11 The aforementioned electronic device 20 . On this basis, the first earphone 11 may perform a first connection back operation corresponding to the first target device, so that the first earphone 11 establishes a Bluetooth connection with the first target device. It can be understood that the above-mentioned first earphone 11 and the second earphone 12 can be interchanged without affecting the realization of the above-mentioned Bluetooth connection method.

By implementing the above method, when the first earphone 11 in the earphone device 10 is in the reconnection state and needs to be reconnected to the electronic device 20, the first earphone 11 can flexibly select different first target devices according to its master-slave attributes (may include the above-mentioned second earphone 12 or electronic device 20) to connect back, to adapt to the application scene where the first earphone 11 is located as much as possible, improve the success rate of the first earphone 11 to connect back to the first target device, and also have Helps shorten the time it takes to connect back. No matter what kind of first target device the first earphone 11 establishes a Bluetooth connection with, it can indirectly or directly realize the connection back to the electronic device 20 , thereby effectively improving the reliability and flexibility of the connection between the earphone device 10 and the electronic device 20 . For example, if the first earphone 11 is the master earphone, then the first earphone 11 can select the electronic device 20 as the first target device to directly realize the connection back with the electronic device 20; if the first earphone 11 is the slave earphone , then the first earphone 11 can select the second earphone 12 as the first target device, so as to first connect back to the second earphone 12 as the main earphone, and then indirectly realize the back-connection with the electronic device 20 through the second earphone 12 .

Exemplarily, the above-mentioned electronic device 20 may include various devices or systems with bluetooth communication functions, such as mobile phones, smart wearable devices, vehicle-mounted terminals, tablet computers, PCs (Personal Computers, personal computers), PDAs (Personal Digital Assistants, personal digital assistant), etc., are not specifically limited in this embodiment of the application. It should be noted that the electronic device 20 shown in FIG. 1 is a mobile phone, which is only an example and does not constitute a limitation on the type of the electronic device 20 in the embodiment of the present application. Exemplarily, the above-mentioned earphone device 20 may include various types of Bluetooth earphones, especially TWS (True Wireless Stereo, true wireless stereo) earphones.

In the embodiment of the present application, the first earphone may refer to any one of the two earphones included in the above-mentioned earphone device (for example, it may be a left-ear earphone or a right-ear earphone). When the first earphone is in the connection back state, the first earphone needs to be reconnected to the electronic device with which the bluetooth connection has been established, that is, to be connected back to the electronic device. In some scenarios, the first earphone can directly connect back to the electronic device, but in other scenarios, it may not be able to directly connect back. Other headphone equipment connection, etc. In order to adapt to different application scenarios, the first earphone in the connection-back state can be connected from the second earphone and the electronic device according to its master-slave attribute (that is, the first earphone is used as the master earphone or the slave earphone in the earphone device). , select an appropriate first target device, so as to perform the connection back operation corresponding to the first target device in the subsequent steps, and avoid specifying the electronic device for connection back in the scenario where the electronic device cannot be directly connected back, which will lead to The connection is slow or even fails.

In some embodiments, the first earphone can be placed in the earphone box, and when the earphone box triggers an opening operation, the first earphone can enter a reconnection state. Exemplarily, when the earphone box is opened by the user (for example, the earphone box with the cover is opened, the earphone box with the opening button is clicked on the opening button, etc.), the first earphone box can be placed inside it. The earphone sends the start signal, so that the first earphone is turned on, or wakes up from the dormant state, and then enters the reconnection state.

In some other embodiments, when the connection between the first earphone and the electronic device is accidentally interrupted, the first earphone may also enter a reconnection state. For example, if the position of the electronic device is beyond the communication range of the first earphone, or the data transmission based on the Bluetooth connection between the electronic device and the first earphone is interfered or blocked, the first earphone can automatically enter the reconnection state , so that the electronic device can be quickly reconnected when the above-mentioned unexpected interruption is resolved.

204. Determine a first target device to be connected back to the first earphone according to the master-slave attribute, where the first target device may include the second earphone or an electronic device that has established a Bluetooth connection with the first earphone.

In the embodiment of the present application, according to the master-slave relationship between the first earphone and the second earphone, the application scenarios of the first earphone before and after entering the reconnection state can be correspondingly determined, and then based on the application scenarios, the adaptability Select the first target device that is easy to connect back and has a high success rate of connection back. Exemplarily, the first target device may include the above-mentioned second earphone (that is, indirectly connect back to the electronic device through the second earphone), or the above-mentioned electronic device that has established a Bluetooth connection with the first earphone (that is, directly connect back to the electronic device) .

In some embodiments, if the first earphone is originally the master earphone, and if the second earphone originally as the slave earphone is within the communication range of the electronic device, then when the first earphone is placed in the earphone box, and the earphone box triggers When the shutdown operation is performed, the first earphone can be switched as a slave earphone, and at the same time, the second earphone can be switched as a master earphone. On this basis, when the earphone box triggers the opening operation so that the first earphone enters the reconnection state, the first earphone can determine that its master-slave attribute is a slave earphone, and then the first earphone can be determined according to this master-slave attribute. The first target device to which the headset is to be connected.

In some other embodiments, if the first earphone is originally the master earphone, if the second earphone originally serving as the slave earphone is not within the communication range of the electronic device (for example, the second earphone is lost, shielded, etc.), then when the first earphone When the earphone is placed in the earphone box, and the earphone box triggers the closing operation, the first earphone is still regarded as the master earphone and will not be switched to the slave earphone. On this basis, when the earphone box triggers the opening operation so that the first earphone enters the reconnection state, the first earphone can determine its master-slave attribute as the master earphone, and then also determine the second earphone according to the master-slave attribute. The first target device to which a headset is to be connected back.

Optionally, when the position of the electronic device is beyond the communication range of the first earphone, the first earphone may also enter the connection back state. Since the second earphone can be switched as the master earphone at this time, based on different switching settings, the master-slave attribute of the first earphone can be regarded as either the master earphone or the slave earphone, and then the determined master-slave attribute can be Further determining the first target device to which the first earphone is to be connected back.

In some other embodiments, if the first earphone is originally a slave earphone, no matter whether the first earphone is placed in the earphone box or exceeds the communication range of the electronic device, the first earphone can determine that its master-slave attribute is Slave the earphone to determine the first target device to be connected back to the first earphone according to the master-slave attribute.

206. Perform a first connection back operation corresponding to the first target device, so that the first headset establishes a Bluetooth connection with the first target device.

In this embodiment of the application, after the first earphone determines the first target device to be connected back, it may perform a corresponding first connection back operation on the first target device. Specifically, according to the fact that the first target device is the above-mentioned second earphone or the electronic device, the first earphone can determine the address information of the first target device, and then can send a connection back request containing the above-mentioned address information to the first target device . After receiving the connection back request, the first target device may respond to the connection back request and re-establish a Bluetooth connection with the first earphone. For example, if the first target device is the above-mentioned electronic device, the first earphone can directly realize the connection back with the electronic device; if the first target device is the above-mentioned second earphone, then the first earphone can first connect back to the second The second earphone, and the second earphone synchronizes the bluetooth connection information with the electronic device to the first earphone, so as to indirectly realize the connection back with the electronic device.

It can be seen that, implementing the Bluetooth connection method described in the above embodiments, when the first earphone in the earphone device is in the reconnection state and needs to be connected back to the electronic device, the first earphone can flexibly select different The first target device (which may include the above-mentioned second earphone or electronic device) is connected back, so as to adapt to the application scenario where the first earphone is located as much as possible, improve the success rate of the first earphone to connect back to the first target device, and shorten the The time required to connect back. No matter what kind of first target device the first earphone establishes a Bluetooth connection with, it can be indirectly or directly connected back to the electronic device, thereby effectively improving the reliability and flexibility of the connection between the earphone and the electronic device.

Please refer to FIG. 3 . FIG. 3 is a schematic flowchart of another Bluetooth connection method disclosed in an embodiment of the present application. This method can be applied to the first earphone of the above-mentioned earphone device, and the earphone device can also include a second earphone. As shown in Figure 3, the Bluetooth connection method may include the following steps:

302. When the first earphone is placed in the earphone box, when the earphone box is in a state of triggering an opening operation, if the second earphone is not placed in the earphone box, acquire the master-slave attribute of the first earphone.

In the embodiment of the present application, the earphone box can be used to place the above-mentioned first earphone and the second earphone at the same time, so as to realize functions such as charging, powering on, and waking up of the first earphone and/or the second earphone. In some embodiments, the above-mentioned earphone box may have a box cover, and the user can realize the opening operation of the earphone box by opening the cover, and realize the closing operation of the earphone box by closing the cover. In some other embodiments, the above-mentioned earphone box can also have an open button, then the user can realize the open operation of the earphone box by clicking the open button, and realize the open operation of the earphone box by clicking the close button (the above-mentioned open button can be reused). close operation.

Exemplarily, taking an earphone box with a box cover as an example, please refer to FIG. 4A and FIG. 4B together. FIG. 4A is a schematic diagram of triggering an opening operation of an earphone box disclosed in an embodiment of the application, that is, opening a cover; FIG. 4B is It is a schematic diagram of triggering the closing operation of the earphone box shown in FIG. 4A , that is, closing the cover. As shown in FIG. 4A and FIG. 4B , both the first earphone 11 and the second earphone 12 can be placed in the earphone box 30 . However, in the embodiment of the present application, only the first earphone 11 is placed in the earphone box 30. , then the first earphone 11 can obtain the master-slave attribute of the first earphone 11, so as to select an appropriate first target device for connection back according to the master-slave attribute in subsequent steps.

In some embodiments, the above-mentioned master-slave attribute of the first earphone may be obtained by the first earphone recorded in advance. Exemplarily, when the above-mentioned first earphone is placed in the earphone box, when the earphone box triggers a closing operation (take the earphone box with a lid as an example, that is, the earphone box is closed), the first earphone can record At this time, the master-slave property of the first headset. On this basis, when the earphone box triggers the opening operation, if the second earphone is not placed in the earphone box, the first earphone can obtain other records recorded by the first earphone when the earphone box was in the state of triggering the closing operation last time. own master-slave properties. For example, if the first earphone is marked as A earphone and the second earphone is marked as B earphone, then in the case that the A earphone is placed in the earphone box, but the B earphone is not placed in the earphone box (that is, one ear into the box ), the earphone box triggers the shutdown operation, and at this time, the A earphone can record its own master-slave property. In the state where the earphone box triggers the opening operation again, the earphone A can obtain the above-mentioned master-slave attributes recorded before, and then can determine the first target device to be connected back in the subsequent steps according to the master-slave attributes.

In some other embodiments, when the above-mentioned A earphone and B earphone are placed in the earphone box (that is, both ears are in the box), the earphone box triggers the closing operation, and at this time, the A earphone can also record its own master-slave attribute . In the state where the earphone box triggers the opening operation again, since the A earphone and the B earphone are placed in the earphone box, the A earphone and the B earphone can be connected back first, so that a Bluetooth connection can be established between the two. On this basis, the master earphone can be determined from the connected earphone A and earphone B according to the master-slave attribute recorded by earphone A; and B earphone to determine the main earphone. Further, the main earphone can be connected back to the electronic device, so that the main earphone can establish a Bluetooth connection with the electronic device. Since earphone A and earphone B can share the same bluetooth address information, after the master earphone is connected back to the above-mentioned electronic device, the master earphone can share the corresponding connection information (such as the bluetooth address information of the electronic device, the bluetooth channel number, etc.) to the slave earphone ( That is, another earphone other than the master earphone), so that the slave earphone can monitor the transmission data between the master earphone and the electronic device.

304. If the above-mentioned master-slave attribute indicates that the first earphone is the master earphone, obtain the connection information corresponding to the electronic device that has established a Bluetooth connection with the first earphone, and determine the electronic device that matches the connection information as the first earphone to be connected back If the above-mentioned master-slave attribute indicates that the first earphone is a slave earphone, determine the second earphone as the first target device to be connected back to the first earphone.

In this embodiment of the application, after the first earphone obtains its own master-slave attribute, it can obtain the master-slave relationship between the first earphone and the second earphone from the second earphone and the electronic One of the devices is selected as the first target device to be connected back to the first earphone. By implementing the above method, the first earphone can select the first target device that is easy to reconnect and has a high reconnection success rate in the current scene to perform subsequent reconnection operations, thereby improving the reliability and flexibility of the first earphone reconnection.

In some embodiments, if the above-mentioned master-slave attribute indicates that the first earphone is the master earphone, it means that the first earphone was the master earphone before the latest disconnection from the electronic device, and the second earphone originally used as the slave earphone does not It is within the communication range of the electronic device (for example, the second earphone is lost, blocked, etc.), so that when the first earphone is placed in the earphone box, and the earphone box triggers the shutdown operation, the first earphone does not have a master-slave The switching of the relationship can record the master-slave attribute of the first earphone at this time as the master earphone. On this basis, since the possibility of failure to connect back to the second earphone is higher, the first earphone can obtain the connection information of the electronic device that has established a Bluetooth connection with the first earphone, and determine the electronic device that matches the connection information as The first target device to be connected back to improve the efficiency and success rate of the connection back. Exemplarily, the above connection information may include Bluetooth address information, Bluetooth channel number, etc. of the electronic device.

In some other embodiments, if the above-mentioned master-slave attribute indicates that the first earphone is a slave earphone, it means that before the first earphone was disconnected from the electronic device last time, the first earphone and the second earphone that was originally a slave earphone They are all within the communication range of the electronic device, so that when the first earphone is placed in the earphone box and the earphone box triggers the closing operation, the first earphone can be switched as the slave earphone (while the second earphone can be switched as the master earphone ), at this time, it can be recorded that the master-slave attribute of the first earphone is the slave earphone. On this basis, since the possibility of successful connection back to the second earphone is higher, the first earphone may determine the second earphone as the first target device to be connected back, so as to further improve the efficiency and success rate of the connection back.

306. Within the first duration, send a first connection-back instruction to the first target device, so that the first target device responds to the first connection-back instruction to establish a Bluetooth connection with the first earphone.

In the embodiment of the present application, after the first earphone determines the first target device to be connected back, it can limit the execution of the first connection back operation corresponding to the first target device within a certain period of time, so as to avoid When the connection fails, it takes too long to try to connect back to the first target device, which reduces the efficiency of the first earphone connection back. It can be understood that if the first earphone fails to successfully connect back to the first target device within the limited time period, the first earphone can try to connect back to other devices that can be connected back in subsequent steps, so as to improve the connection back as much as possible. Success rate.

Specifically, the first earphone may send the first connection-back instruction to the first target device within a first duration (for example, 3 seconds, 5 seconds, etc.). Exemplarily, the first connection back instruction may include a connection back request, and the connection back request may include address information of the above-mentioned first target device. On this basis, after receiving the first connection-back instruction, the first target device may re-establish a Bluetooth connection with the first earphone in response to the first connection-back instruction.

308. If the first earphone fails to establish a Bluetooth connection with the first target device within the first time period, perform a second reconnection operation with another device other than the first target device among the second earphone and the electronic device.

In this embodiment of the present application, when the first headset fails to establish a Bluetooth connection with the first target device within the specified first time period (for example, the first target device does not respond to the above-mentioned first connection back instruction, or the first target device sends If an earphone sends a connection failure message, etc.), the first earphone may try to connect back to other devices that can be connected back.

In some embodiments, when the master-slave property of the first earphone is the master earphone, the first target device is the above-mentioned electronic device. At this time, if the first earphone fails to connect back to the electronic device within the first duration, the The second earphone is determined as the second target device, and a second connection back operation corresponding to the second target device (ie, the second earphone) is performed. Specifically, the first earphone may also send a corresponding connection-back instruction to the second earphone within a certain period of time (for example, 3 seconds, 5 seconds, etc.), so that the second earphone responds to the connection-back instruction and establishes a Bluetooth connection with the first earphone.

In some other embodiments, when the master-slave attribute of the first earphone is the slave earphone, the first target device is the second earphone, and if the first earphone fails to connect back to the second earphone within the first duration, Then the aforementioned electronic device may be determined as the second target device, and a second connection back operation corresponding to the second target device (that is, the electronic device) is performed. Specifically, the first earphone may also send a corresponding connection-back instruction to the electronic device within a certain period of time (for example, 3 seconds, 5 seconds, etc.), so that the electronic device can respond to the connection-back instruction within the period of time, and the same as the first earphone. The headset establishes a Bluetooth connection.

310. If the first earphone fails to establish a Bluetooth connection with the other device, perform the first connection-back operation and the second connection-back operation in turn until the target total duration is reached.

In this embodiment of the application, if the first earphone has not successfully established a Bluetooth connection with the other device (that is, the second target device, such as the second earphone or an electronic device) within a specified period of time, the first target can be executed again. The first connection back operation of the device; if it still fails, the second connection back operation for the second target device can be performed again, and so on. That is to say, the first earphone can perform the above-mentioned first connection back operation and the second connection back operation in turn, so as to continuously try to connect back with the second earphone or electronic device, and increase the possibility of successful connection back of the first earphone as much as possible. sex.

It should be noted that there may be limitations on the duration of the first earphone performing the above-mentioned first connection-back operation or the second connection-back operation, wherein the duration of performing the first connection-back operation may be longer than the duration of performing the second connection-back operation, or It can be shorter than the time for performing the second connection back operation, or both can be equal. Further, the total time for the first earphone to perform the above-mentioned first connection back operation and the second connection back operation in turn may also be limited, that is, the first earphone can perform the first connection back operation and the second connection back operation in turn until the target is reached. The total duration (for example, 10 seconds, 15 seconds, etc.), so that the first earphone can only try a limited number of reconnection attempts for the second earphone or electronic device, so as to avoid too much time for trying to reconnect when it is really impossible to reconnect. long.
