Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings of the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

It should be noted that the terms "comprises" and "comprising," along with any variations thereof, in the embodiments of the present application are intended to cover non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus, but may include other steps or elements not expressly listed. In case of no conflict, the embodiments, implementations and related technical features in the present application may be combined with each other and replaced, and the explanations in the different embodiments and implementations may be mutually applicable. The term "plurality" in this application means two or more.

The following detailed description will be given with reference to the accompanying drawings.

Referring to fig. 1A and fig. 1B together, fig. 1A is a schematic view of an application scenario of a bluetooth connection method disclosed in an embodiment of the present application, and fig. 1B is a schematic view of another application scenario of the bluetooth connection method disclosed in an embodiment of the present application. As shown in fig. 1A, the application scenario may include a bluetooth device 10 and a terminal device 20, where the bluetooth device 10 may establish a bluetooth connection with the terminal device 20, such as a classical bluetooth connection, a BLE (Bluetooth Low Energy ) connection, etc. The classical bluetooth connection refers to a bluetooth connection scheme implemented based on technologies (or modes) such as BR/EDR (Basic Rate/Enhanced Data Rate) and AMP (alternative MAC/PHYs) specified in bluetooth protocols of various versions; the above BLE connection refers to a bluetooth connection scheme implemented based on LE (Low Energy) technology (or mode). It should be noted that, in order to realize Audio data transmission with larger data flow on the basis of keeping the power consumption of the device Low, the bluetooth device 10 may also establish an LE Audio (Low Energy Audio) bluetooth connection with the terminal device 20.

It will be appreciated that bluetooth device 10 may establish at least one classical bluetooth link and at least one LE Audio bluetooth link simultaneously with terminal device 20, i.e. bluetooth device 10 may establish both a classical bluetooth connection and an LE Audio bluetooth connection simultaneously with terminal device 20. In some possible embodiments, if the bluetooth device 10 comprises a plurality of devices, the terminal device 20 may establish a classical bluetooth connection with only one of the bluetooth devices 10, which may be defined as the master device. The two types of bluetooth links exist at the same time, so that the bluetooth device 10 and the terminal device 20 can more conveniently perform classical bluetooth transmission and LE Audio bluetooth transmission, thereby respectively utilizing the advantages of different types of bluetooth protocols and rapidly performing switching.

It will be appreciated that one or more devices may be included in the bluetooth device 10, and that in order to better use the bluetooth device 10 in which both types of bluetooth links are present, each of the devices in the bluetooth device 10 may be provided with the same bluetooth address with respect to the terminal device 20, so that only one classical bluetooth device address may be perceived on the side of the terminal device 20. In some embodiments, the BLE address may be different for each of the bluetooth devices 10. In some embodiments, the classical bluetooth address of the default master device (which may be understood as the device that establishes the classical bluetooth connection with the terminal device 20 in the default condition set before factory) in the bluetooth device 10 may be the same as the BLE address, and the classical bluetooth address of the default slave device (which may be understood as the device that does not establish the classical bluetooth connection with the terminal device 20 in the default condition set before factory) may be different from the BLE address. In some embodiments, the LE Audio broadcast of the slave device may be set to be an invisible broadcast, so that on the terminal device 20, the bluetooth device 10 may correspond to only one bluetooth address (i.e., the bluetooth address of the master device), which is convenient for the user to operate. Of course, the above address setting method is merely an example, and other address setting methods are also possible.

It should be understood that the above establishment of the bluetooth connection may be a communication link based on a bluetooth protocol (e.g. a standard bluetooth protocol or a proprietary bluetooth protocol), for example, a classical bluetooth connection may be considered to include establishment of a bluetooth physical link such as ACL (Asynchronous Connection less ) or SCO (Synchronous Connection Oriented, synchronous directional link), or may be considered to include establishment of an upper layer protocol connection such as A2DP (Advanced Audio Distribution Profile, advanced audio delivery specification) or HFP (handles-Free-Profile, hands-Free specification), and the specification of the relevant bluetooth protocol may be referred to specifically, without limitation in the present application.

By way of example, the Bluetooth device 10 may include various types of Bluetooth headsets, bluetooth speakers, etc., and may include TWS (True Wireless Stereo ) headsets, among others. For example, the terminal device 20 may include various devices or systems with bluetooth communication functions, such as a mobile phone, a smart wearable device, a vehicle-mounted terminal, a tablet computer, a PC (Personal Computer, a personal computer), a PDA (Personal Digital Assistant, a personal digital assistant), and the like, which are not limited in the embodiments of the present application. It should be noted that, the bluetooth device 10 shown in fig. 1A and fig. 1B is a bluetooth headset, and the terminal device 20 is a mobile phone, which is merely an example, and does not limit the device types of the bluetooth device 10 and the terminal device 20 in the embodiment of the present application. Taking the example of the bluetooth device 10 described above including a headset device, in some embodiments, the headset device may include only a single headset, as shown in fig. 1A. In yet other embodiments, as shown in fig. 1B, the earphone device may also comprise a first earphone 11 and a second earphone 12. Wherein the first earpiece 11 and the second earpiece 12, as the same group of bluetooth devices 10, may share the same BT address, but may use different BLE addresses. As a possible implementation, one of the first earpiece 11 and the second earpiece 12 may establish a classical bluetooth connection with the terminal device 20 (which may be understood as the current master earpiece or master device), so that the first earpiece 11 and the second earpiece 12 may distinguish between master and slave ears to implement a classical bluetooth connection with the terminal device 20; meanwhile, the first earphone 11 and the second earphone 12 may also respectively establish LE Audio bluetooth connection with the terminal device 20. Alternatively, the first earphone 11 and the second earphone 12 may not distinguish between the master ear and the slave ear, so that the first earphone 11 and the second earphone 12 may implement a classical bluetooth connection and an LE Audio bluetooth connection with the terminal device 20, respectively.

It will be appreciated that the bluetooth device 10 may also include more than two devices in the same group, and the manner in which each device in the same group establishes a bluetooth connection with the terminal device 20 may be similar to the manner in which the first earphone 11 and the second earphone 12 establish a bluetooth connection with the terminal device 20.

In this embodiment of the present application, if the bluetooth device 10 needs to establish an LE Audio bluetooth connection with the terminal device 20, in a case where the bluetooth device 10 establishes a classical bluetooth connection with the terminal device 20, the bluetooth device 10 may start a low-power Audio LE Audio broadcast, so that the terminal device 20 may respond to the LE Audio broadcast and feed back a corresponding LE Audio connection request to the bluetooth device 10, so that the bluetooth device 10 may receive the LE Audio connection request fed back by the terminal device 20 and establish an LE Audio bluetooth connection with the terminal device 20 according to the connection request.

It will be appreciated that in the case where the bluetooth device 10 establishes a classical bluetooth connection with the terminal device 20, it may be understood that the classical bluetooth connection is established in some intermediate process of the bluetooth device 10 establishing the classical bluetooth connection with the terminal device 20 or after it is determined. It will be appreciated that the bluetooth device 10 may not continue to maintain the broadcast after the LE Audio broadcast is turned on, for example, may stop after a certain period of time of the broadcast, or stop after determining that the LE Audio bluetooth connection is successful. In some intermediate process, the bluetooth device 10 may receive a classical bluetooth connection request sent by the terminal device 10, for example, a paging page packet, and of course, may also be other interaction phases in the process of establishing a classical bluetooth connection between the bluetooth device 10 and the terminal device 20. The establishment of the classical bluetooth connection may be initiated by the bluetooth device 10 or by the terminal device 20.

By implementing the method, the bluetooth device 10 can start the whole LE Audio connection flow by conditionally starting the LE Audio broadcast, for example, starting the LE Audio broadcast when the bluetooth device starts to connect with the terminal device 20 through classical bluetooth, at this time, the bluetooth device 10 has higher possibility of connecting with the terminal device 20, and can avoid continuous and long-time invalid broadcast, thereby effectively reducing the power consumption of the bluetooth device 10 in the process of establishing connection with the terminal device 20, and being beneficial to improving the duration of the bluetooth device 10, and enabling the user to obtain better use experience.

In some embodiments, in the case where the above bluetooth device 10 includes a headset device and the headset device includes a first headset 11 and a second headset 12, when the headset device (i.e., the first headset 11 and/or the second headset 12) establishes a classical bluetooth connection with the terminal device 20, the first headset 11 and the second headset 12 respectively start respective LE Audio broadcasts, and the first headset 11 and/or the second headset 12 receive LE Audio connection requests fed back by the terminal device 20, so that according to the connection requests, LE Audio bluetooth connections are established by the first headset 11 and the second headset 12 respectively with the terminal device 20, so that bluetooth connections between multiple devices of the same group and the terminal device 20 can be implemented.

Referring to fig. 2, fig. 2 is a schematic flow chart of a bluetooth connection method disclosed in an embodiment of the present application, and the method may be applied to the above bluetooth device. As shown in fig. 2, the bluetooth connection method may include the steps of:

202. and under the condition that the Bluetooth equipment and the terminal equipment establish classical Bluetooth connection, starting low-power Audio LE Audio broadcasting.

In the related art, when the bluetooth device needs to establish an LE Audio bluetooth connection with the terminal device, the entire LE Audio connection procedure may be started by starting LE Audio broadcast. However, it is unknown for the bluetooth device whether the LE Audio broadcast sent by the bluetooth device can be received by the terminal device, so that the bluetooth device is often required to continuously start the broadcast until a connection is successfully established with the terminal device. In the embodiment of the application, in order to avoid continuous and long-time invalid broadcasting by the bluetooth device, the bluetooth device may start LE Audio broadcasting when it is possible to connect to the terminal device. Specifically, when the bluetooth device and the terminal device establish classical bluetooth connection, the possibility that the bluetooth device and the terminal device further establish LE Audio bluetooth connection is high, so that the bluetooth device can start its own LE Audio broadcast when the bluetooth device and the terminal device establish classical bluetooth connection, so that LE Audio bluetooth connection can be established with the terminal device in a subsequent step.

For example, in order to confirm whether the bluetooth device starts to establish a classical bluetooth connection with the terminal device, a classical bluetooth connection request sent by the bluetooth device or the terminal device to the other party may be used as an identifier, and if the bluetooth device receives a data packet related to the classical bluetooth connection request, the process of establishing the classical bluetooth connection between the bluetooth device and the terminal device may be considered to have started, so that the bluetooth device may trigger itself to start LE Audio broadcasting.

In some embodiments, the LE Audio broadcast may be turned on when the bluetooth device receives a first classical bluetooth connection request sent by the terminal device to the bluetooth device. Taking the example that the terminal device connects back to the bluetooth device, in the connection process, the terminal device may send a page packet (i.e. a data packet corresponding to the first classical bluetooth connection request) to the bluetooth device, and the bluetooth device may start a page scan mode, so as to respond to the corresponding first classical bluetooth connection request when receiving the page packet, and attempt to establish a classical bluetooth connection with the terminal device. Meanwhile, when the bluetooth device receives the page packet, the bluetooth device can confirm that the process of establishing classical bluetooth connection between the bluetooth device and the terminal device is started, so that the bluetooth device can start its own LE Audio broadcast.

The above-mentioned connection may refer to an operation that the first electronic device attempts to connect with the previously paired and connected second electronic device again by paging. For example, a first electronic device may send a page package to a second electronic device that may be used to connect or activate the second electronic device so that the first electronic device may establish a communication connection with the second electronic device. The page packet may include bluetooth address information of the second electronic device, so that the second electronic device may be directly paged.

In other embodiments, when the bluetooth device sends a second classical bluetooth connection request to the terminal device, the bluetooth device may also turn on the LE Audio broadcast. Optionally, when the bluetooth device sends a second classical bluetooth connection request to the terminal device and receives the request feedback information fed back by the terminal device in response to the second classical bluetooth connection request, the bluetooth device starts LE Audio broadcasting. In the latter case, for example, when the bluetooth device connects back to the terminal device, the bluetooth device may send a page packet (i.e. a data packet corresponding to the second classical bluetooth connection request) to the terminal device, so that after receiving the page packet, the terminal device may send corresponding request feedback information to the bluetooth device. On the basis, when the Bluetooth device receives the request feedback information, the Bluetooth device can confirm that the process of establishing classical Bluetooth connection between the Bluetooth device and the terminal device is started, so that the Bluetooth device can start LE Audio broadcasting of the Bluetooth device.

204. Receiving LE Audio connection request of the terminal equipment in response to LE Audio broadcast feedback, and establishing LE Audio Bluetooth connection with the terminal equipment according to the connection request.

In this embodiment of the present application, after the bluetooth device starts the LE Audio broadcast, if the terminal device receives the corresponding broadcast packet, the corresponding LE Audio connection request may be fed back to the bluetooth device in response to the LE Audio broadcast (i.e., the corresponding connection request packet is sent to the bluetooth device). On the basis, when the Bluetooth device receives the connection request, a subsequent connection step can be executed according to the connection request so as to establish LE Audio Bluetooth connection with the terminal device.

Illustratively, the bluetooth device may broadcast an adv_ind packet (denoted as A1) to its surrounding space after turning on LE Audio broadcasting. After receiving the data packet A1, the terminal device may obtain BLE connection information (for example, BLE address, BLE connection state, etc.) of the bluetooth device based on the analysis result of the data packet A1, and then may send a corresponding LE Audio connection request (denoted as A2) to the bluetooth device, so that the bluetooth device may establish LE Audio bluetooth connection with the terminal device after receiving the data packet A2.

For example, after receiving the above data packet A2, the bluetooth device may keep open its radio frequency receiving Window for a specified time (i.e. during Transmit Window specified by LE technology), so that the first synchronization data packet (denoted as P1) sent by the terminal device may be continuously received, so as to achieve time synchronization based on the synchronization data packet P1, so as to facilitate subsequent data transmission. It should be noted that, the synchronization packet P1 may be sent to the bluetooth device by the terminal device after the packet A2 is sent to the bluetooth device, for a specified time. On the basis, after receiving the synchronous data packet P1, the bluetooth device may reply to the terminal device with connection confirmation information, that is, send an ACK data packet (denoted as P2) to the terminal device, and once the terminal device receives the data packet P2, it may confirm that the bluetooth device and the terminal device successfully establish the LE Audio bluetooth connection.

In some embodiments, the data packet P2 may be lost, but if the terminal device receives any ACK data packet sent by the bluetooth device within a specified time (i.e. until the period of Supervision Timeout specified by the LE technology), it may also confirm that the bluetooth device successfully establishes the LE Audio bluetooth connection with the terminal device.

It can be seen that, if the bluetooth device needs to establish LE Audio bluetooth connection with the terminal device, the bluetooth device starts the entire LE Audio connection procedure by starting LE Audio broadcast when establishing classical bluetooth connection with the terminal device. Therefore, the Bluetooth device can conditionally start LE Audio broadcasting, for example, when the Bluetooth device starts to connect with the terminal device through classical Bluetooth, the possibility that the Bluetooth device is connected with the terminal device is higher, and invalid broadcasting can be avoided continuously and for a long time, so that the power consumption of the Bluetooth device in the process of establishing connection with the terminal device is effectively reduced, and the duration of the Bluetooth device is prolonged.

Referring to fig. 3, fig. 3 is a schematic flow chart of another bluetooth connection method disclosed in an embodiment of the present application, where the method may be applied to the bluetooth device described above, the bluetooth device may include a headset device, and the headset device may include a first headset and a second headset. As shown in fig. 3, the bluetooth connection method may include the steps of:

302. and under the condition that the earphone equipment and the terminal equipment establish classical Bluetooth connection, respectively starting LE Audio broadcasting by the first earphone and the second earphone.

In this embodiment of the present application, based on a main body difference of initiating a classical bluetooth connection request (for example, a page packet may be sent by a terminal device or different devices in the same group of bluetooth devices in different scenarios), or a main body difference of responding to the classical bluetooth connection request (for example, a page scan mode may be started by one or more devices in the terminal device or the same group of bluetooth devices in different scenarios to receive a page packet), when a classical bluetooth connection is established between a headset device and a terminal device, a classical bluetooth connection may be established between a first headset in the headset device and the terminal device, a classical bluetooth connection may be established between a second headset in the headset device and the terminal device, or the above-mentioned first headset and second headset may simultaneously establish a classical bluetooth connection with the terminal device. The first earphone may represent any one of two earphones (for example, a left-ear earphone or a right-ear earphone) included in the earphone device, and the second earphone may represent the other earphone. On the basis, no matter how the earphone device establishes classical Bluetooth connection with the terminal device, the first earphone and the second earphone in the earphone device can start respective LE Audio broadcast so as to respectively establish LE Audio Bluetooth connection with the terminal device in the subsequent step.

In some embodiments, the first earphone and the second earphone may have a master-slave relationship, for example, the first earphone may be a master earphone, and the second earphone may be a slave earphone, where a classical bluetooth connection may be established between the first earphone as the master earphone and the terminal device, and the first earphone and the second earphone connected to the first earphone may be triggered to start LE Audio broadcast respectively. For example, in case the first earpiece establishes a classical bluetooth connection with the terminal device, the first earpiece may be triggered to turn on the LE Audio broadcast. On the basis, when the second earphone acquires connection event information of the classical Bluetooth connection between the first earphone and the terminal equipment through Bluetooth connection between the second earphone and the first earphone, the second earphone can be further triggered to start LE Audio broadcasting.

As an optional implementation manner, the first earphone may actively send the connection event information to the second earphone, so as to achieve information synchronization between the first earphone and the second earphone, and trigger the second earphone to start LE Audio broadcast. For example, when the first earphone and the terminal device establish a classical bluetooth connection (for example, the first earphone receives a first classical bluetooth connection request sent by the terminal device, or the first earphone sends a second classical bluetooth connection request to the terminal device and receives request feedback information fed back by the terminal device), a broadcast start instruction may be sent by the first earphone to the second earphone when the first earphone and the second earphone establish a bluetooth connection, and the second earphone is triggered to start LE Audio broadcast by the broadcast start instruction. The broadcast start command may include connection event information that the first earphone and the terminal device establish classical bluetooth connection.

As another optional implementation manner, the second earphone may also acquire the connection event information by using a listening manner, and trigger itself to start LE Audio broadcasting based on the connection event information. For example, when the first earphone and the terminal device establish the classical bluetooth connection, if the data transmission link between the first earphone and the terminal device is established, the second earphone can confirm the connection event information of the classical bluetooth connection established between the first earphone and the terminal device when the second earphone monitors the data transmission link, so as to start the LE Audio broadcast of the second earphone.

In other embodiments, the first earphone and the second earphone may also respectively and independently establish a classical bluetooth connection with the terminal device, and then respectively and independently turn on LE Audio broadcasting. In an exemplary embodiment, when the first earphone receives a third classical bluetooth connection request sent by the terminal device and the second earphone is in a scanning on state, LE Audio broadcasting may be started by the first earphone; meanwhile, the second earphone can also receive the third classical bluetooth connection request, so that the second earphone can also start LE Audio broadcasting.

It will be appreciated that the scan on state described above includes a page scan on state, such as the page scan mode of the first earpiece and/or the second earpiece being on. In some cases, the scan on state also includes querying a scan in scan on state, for example, the in scan mode of the first earphone and/or the second earphone is in an on state, which may be specifically set according to the actual requirement of the product.

For example, the first earphone and the second earphone may share the same BT address, so after the page scan mode is started, the page packets sent by the terminal device to the BT address may be received respectively, and then LE Audio broadcasting may be started respectively.

304. And receiving an LE Audio connection request which is fed back by the terminal equipment in response to the LE Audio broadcasting by the first earphone and/or the second earphone, and respectively establishing LE Audio Bluetooth connection with the terminal equipment by the first earphone and the second earphone according to the connection request.

Step 304 is similar to step 204 described above. In the embodiment of the application, the first earphone and the second earphone in the earphone device can both receive the LE Audio connection request of the terminal device in response to the LE Audio broadcast feedback, so that LE Audio bluetooth connection can be respectively established with the terminal device based on the connection request.

For example, when the first earphone receives the first LE Audio connection request (i.e. the data packet A2) sent by the terminal device and the first synchronization information (i.e. the data packet P1) sent by the terminal device after sending the first LE Audio connection request, the first earphone may send, in response to the first synchronization information, first connection acknowledgement information (i.e. the data packet P2) to the terminal device, so as to acknowledge the LE Audio bluetooth connection established between the first earphone and the terminal device. The first LE Audio connection request may be fed back to the first earphone by the terminal device in response to an LE Audio broadcast sent by the first earphone.

Similarly, when the second earphone receives the second LE Audio connection request (i.e. the data packet A2) sent by the terminal device and the second synchronization information (i.e. the data packet P1) sent after sending the second LE Audio connection request, the second earphone may also send, in response to the second synchronization information, second connection confirmation information (i.e. the data packet P2) to the terminal device, so as to confirm the LE Audio bluetooth connection established between the second earphone and the terminal device. Optionally, if the first earphone is the master earphone and the second earphone is the slave earphone, after the terminal device establishes LE Audio bluetooth connection with the first earphone, the terminal device may further determine whether the first earphone is matched with the second earphone in response to the LE Audio broadcast sent by the second earphone, and if the first earphone is matched with the second earphone, the terminal device may feed back the second LE Audio connection request to the second earphone, so as to ensure that the terminal device may respectively establish LE Audio bluetooth connection with the bluetooth device in the same combination.

The terminal device may obtain the SIPK (Set Identity Resolving Key, combined identifier resolution value) corresponding to the first earphone after the LE Audio bluetooth connection is established with the first earphone, so that when the terminal device further obtains the LE Audio broadcast data packet sent by the second earphone, the terminal device may analyze the broadcast data packet, and calculate the SIPK corresponding to the second earphone. Based on this, the terminal device may compare the SIPK corresponding to the first earphone with the SIPK corresponding to the second earphone, so as to determine whether the first earphone and the second earphone are matched, i.e. whether the first earphone and the second earphone belong to the same bluetooth device.

Therefore, by implementing the bluetooth connection method described in the above embodiment, the bluetooth device can conditionally start LE Audio broadcasting, that is, associated with establishing a classical bluetooth connection, for example, when the bluetooth device starts to connect with a terminal device through the classical bluetooth, so that the possibility that the bluetooth device is connected with the terminal device is higher, and the classical bluetooth connection does not need to receive a broadcast packet sent by the bluetooth device, and only needs to open a page scan mode, or open the page scan mode and the required scan mode, so that the terminal device can initiate the classical bluetooth connection, thereby avoiding continuous and long-time invalid broadcasting, effectively reducing the power consumption of the bluetooth device in the process of establishing connection with the terminal device, and being beneficial to improving the duration of the bluetooth device. In addition, when bluetooth equipment includes earphone equipment, open LE Audio broadcast respectively through a pair of earphone, can establish LE Audio bluetooth with terminal equipment independently respectively to can effectively reduce the time delay of bluetooth equipment on Audio data transmission, can realize dual mode connection simultaneously on classical bluetooth connection's basis, be favorable to promoting bluetooth equipment and terminal equipment and carry out bluetooth connection's flexibility and reliability.

Referring to fig. 4, fig. 4 is a schematic flow chart of another bluetooth connection method disclosed in an embodiment of the present application, where the method may be applied to the above-mentioned bluetooth device of the ear, the bluetooth device may include an earphone device, and the earphone device may include a first earphone and a second earphone. The first earphone may be a master earphone, and the second earphone may be a slave earphone. As shown in fig. 4, the bluetooth connection method may include the steps of:

402. and the Bluetooth equipment starts LE Audio broadcasting in the first time period, and stops LE Audio broadcasting if the Bluetooth equipment does not successfully establish LE Audio Bluetooth connection with the terminal equipment in the first time period.

In this embodiment of the present application, the bluetooth device may first start LE Audio broadcast for a first period of time (for example, 100 seconds, 120 seconds, etc.), and if the LE Audio bluetooth connection is not successfully established with the terminal device during the first period of time, the LE Audio broadcast is stopped first, and if classical bluetooth connection is subsequently established with the terminal device, the LE Audio broadcast is then conditionally started. The broadcasting mode can avoid the continuous and long-time invalid broadcasting of the Bluetooth equipment, and effectively reduces the power consumption of the Bluetooth equipment in the process of establishing connection with the terminal equipment. It can be appreciated that if the bluetooth device successfully establishes an LE Audio bluetooth connection with the terminal device during the first duration, LE Audio broadcasting may be stopped immediately.

It should be noted that the bluetooth device may include a headset device, and is applicable to different situations including only a single headset or including a pair of headset (i.e., a first headset and a second headset). Optionally, if one of the two earphones successfully establishes the LE Audio bluetooth connection with the terminal device within the first duration, the one earphone may immediately stop the LE Audio broadcast, and at this time, the other earphone may continue broadcasting until the LE Audio bluetooth connection is successfully established with the terminal device, or the first duration is reached.

In some embodiments, when the bluetooth device includes a headset device, the headset device may be placed in a headset box, so that the first time period may be counted from a transition of the headset box from the closed state to the open state. For example, in a case where the headphone device is placed in the headphone case, the headphone device may turn on LE Audio broadcasting when it is determined that the headphone case is transitioned from the off state to the on state.
