In actual applications, Bluetooth devices with the same connection status and HiSyncID may be identified as a device group, that is, each Bluetooth device in the same device group has the same connection status and HiSyncID. The first device group may be any device group, and the first device group may include at least two target Bluetooth devices, both of which have the same connection status and HiSyncID.

[0097] In some embodiments, before adding the target Bluetooth device with the same connection status and HiSyncID in the paired Bluetooth device list to the same device group in the target display list, it may also include: obtaining the connection status of the target Bluetooth device in the paired Bluetooth device list; and obtaining the HiSyncID of the target Bluetooth device based on the UUID reported by the target Bluetooth device.

[0098] In actual applications, UUID can be used to identify the application layer specification of the Bluetooth device, that is, whether the Bluetooth device supports the A2DP protocol, the LE Audio protocol, or the ASHA protocol. Since the UUIDs of Bluetooth devices that support the ASHA protocol and the LE Audio protocol are different, the UUID can be used to identify whether the Bluetooth device supports the ASHA protocol. When the UUID is determined to be a device that supports the ASHA protocol type (that is, when the Bluetooth device is a target Bluetooth device that supports the ASHA protocol), the HiSyncID of the target Bluetooth device can be obtained according to the UUID of the target Bluetooth device.

[0099] In some embodiments, since the target Bluetooth device provides Audio Streaming for Hearing Aid (ASHA) GATT service to the outside world, the display device can send a GATT query request to the target Bluetooth device. In response to the query request, the target Bluetooth device reports the UUID of the target Bluetooth device to the display device. Furthermore, the display device can obtain the HiSyncID of the target Bluetooth device based on the UUID of the target Bluetooth device.

[0100] In an embodiment of the present disclosure, after obtaining a list of paired Bluetooth devices, the connection status of the target Bluetooth device in the paired Bluetooth device list, and obtaining the HiSyncID of the target Bluetooth device based on the UUID reported by the target Bluetooth status, the target Bluetooth devices with the same connection status and HiSyncID can also be added to the same device group in the target display list.

[0101] For example, it is assumed that the list of paired Bluetooth devices may include Bluetooth device A, Bluetooth device B, Bluetooth device C and Bluetooth device D; wherein, the HiSyncID corresponding to the obtained Bluetooth device A is 11, and the connection status is connected, the HiSyncID corresponding to the Bluetooth device B is 22, and the connection status is connected, the HiSyncID corresponding to the Bluetooth device C is 11, and the connection status is disconnected, and the HiSyncID corresponding to the Bluetooth device D is 22, and the connection status is connected.

[0102] Among the above Bluetooth devices, if Bluetooth device B and Bluetooth device D have the same connection status and HiSyncID, Bluetooth device B and Bluetooth device D are added to the same device group in the target display list, for example, device group 1. In addition, the target display list may also include device group 2, where device group 2 may include Bluetooth device E (HiSyncID is 33, connection status is not connected) and Bluetooth device F (HiSyncID is 33, connection status is not connected).

[0103] As shown in Figure 9, a schematic diagram of the display effect of a target Bluetooth device when the connection status and HiSyncID are the same according to some embodiments. In the system framework layer, multiple target Bluetooth devices in the same device group are identified by left ear device and right ear device respectively; setting management can be used to display the display effect of the target Bluetooth device on the display. For target Bluetooth devices with the same connection status and HiSyncID, only one device group is displayed on the device management page, such as "Bluetooth device A (left and right) connected".

[0104] S803: Control the display to display a first group identifier and a connection status identifier corresponding to the first group identifier based on the target display list.

[0105] The first group identifier may be used to identify the first device group in the target display list, and the connection status identifier may be used to represent the connection status of the target Bluetooth device in the first device group.

[0106] In the embodiment of the present disclosure, the target display list may include at least a first device group, and the first device group may include at least two target Bluetooth devices with the same connection status and HiSyncID.

[0107] In an embodiment of the present disclosure, after adding the target Bluetooth devices with the same connection status and HiSyncID in the paired Bluetooth device list to the same device group in the target display list, the control display is controlled to display the first group identifier and the connection status identifier corresponding to the first group identifier based on the target display list.

[0108] In the embodiment of the present disclosure, the first group identifier may be used to identify the first device group in the target display list, and the connection status identifier may be used to represent the connection status of the target Bluetooth device in the first device group.

[0109] In some embodiments, the first group identifier may be the device identifier of a target Bluetooth device that is preferentially added to the first device group. For example, the device identifier, such as the device name, of the first target Bluetooth device added to the first device group may be determined as the first group identifier corresponding to the first device group.

[0110] FIG10 is a schematic diagram of a device management page according to some embodiments, wherein the device management page displays a first group identifier 1001 corresponding to a first device group, and may also display the connection status 1002 of a target Bluetooth device in the first device group. The first group identifier may include the device name of the target Bluetooth device, such as "Bluetooth Device A (left and right)", and the connection status may include the display words "connected" or "not connected", a connected icon or a not connected icon, etc.

[0111] In an optional embodiment, the target display list may also include a sixth device group, and the sixth device group may only include the fourth target Bluetooth device. Therefore, when controlling the display to display the first group identifier and the connection status identifier corresponding to the first group identifier based on the target display list, the display may also be controlled to display the device identifier, left and right ear identifiers, and connection status identifier of the fourth target Bluetooth device based on the target display list.

[0112] In the embodiment of the present disclosure, the left and right ear identifiers may be used to identify whether the fourth target Bluetooth device belongs to the left ear or the right ear.

[0113] As shown in Figure 11, this is a schematic diagram of another device management page according to some embodiments, wherein the sixth device group where the fourth target Bluetooth device is located can only include the fourth target Bluetooth device, and the page displays the device identifier 1101, left and right ear identifiers 1102, and connection status identifier 1103 of the fourth target Bluetooth device.

[0114] According to some embodiments of the device control method, first, a list of paired Bluetooth devices is obtained, wherein the list of paired Bluetooth devices may include at least one Bluetooth device; then, the target Bluetooth device in the paired Bluetooth device list with the same connection status and HiSyncID is added to the same device group in the target display list, wherein the target Bluetooth device supports the ASHA protocol, the connection status may include a connected state and an unconnected state, the target display list may include at least a first device group, and the first device group may include at least two target Bluetooth devices; further, the display is controlled to display a first group identifier and a connection status identifier corresponding to the first group identifier based on the target display list; wherein the first group identifier can be used to identify the first device group in the target display list, and the connection status identifier can be used to characterize the connection status of the target Bluetooth device in the first device group. It can be seen that the embodiment of the present disclosure can add target Bluetooth devices with the same connection status and HiSyncID to the same device group, and display them as the same device group on the display, thereby realizing the display function for Bluetooth devices supporting the ASHA protocol.

[0115] 12 , as an extension and refinement of the embodiment shown in FIG. 8 , based on steps S801 to S803 shown in FIG. 8 , step S802 (adding target Bluetooth devices with the same connection status and HiSyncID in the paired Bluetooth device list to the same device group in the target display list) is replaced by steps S1201 to S1203. The device control method according to some embodiments may further include the following steps:

[0116] S801: Acquire a list of paired Bluetooth devices; wherein the list of paired Bluetooth devices may include at least one Bluetooth device.

[0117] S1201: traverse the paired Bluetooth device list, and match the HiSyncID of the first target Bluetooth device in the paired Bluetooth device list with the HiSyncIDs of target Bluetooth devices in each device group in the target display list.

[0118] In the embodiment of the present disclosure, the target Bluetooth device is a Bluetooth device that supports the ASHA protocol. The paired Bluetooth device list may include one or more target Bluetooth devices. The first target Bluetooth device may be any target Bluetooth device. The target display list may include at least one device group, and each device group corresponds to one or more target Bluetooth devices.

[0119] In the embodiment of the present disclosure, after obtaining the paired Bluetooth device list, the paired Bluetooth device list is traversed, and the HiSyncID of the first target Bluetooth device in the paired Bluetooth device list is matched with the HiSyncID of the target Bluetooth device in each device group in the target display list.

[0120] S1202: If the HiSyncID of the first target Bluetooth device successfully matches the HiSyncID of the second target Bluetooth device in the second device group, the first target Bluetooth device is added to the second device group.

[0121] In the embodiment of the present disclosure, the second device belongs to the device group in the target display list, and the second device group may include at least a second target Bluetooth device. The HiSyncID of the second target Bluetooth device is the same as the HiSyncID of the first target Bluetooth device. After the first target Bluetooth device is added to the second device group, the second target Bluetooth device and the first target Bluetooth device are devices in the same device group (i.e., the second device group).

[0122] In some embodiments, the list of paired Bluetooth devices can also be traversed to match the HiSyncID and connection status of the first target Bluetooth device in the paired Bluetooth device list with the HiSyncID and connection status of the target Bluetooth devices in each device group in the target display list, so that when it is determined that the HiSyncID and connection status of the first target Bluetooth device successfully match the HiSyncID and connection status of the second target Bluetooth device in the second device group, the first target Bluetooth device can be added to the second device group.

[0123] S1203: If the HiSyncID of the first target Bluetooth device does not match the HiSyncID of the target Bluetooth device in the device group in the target display list, create a third device group for the first target Bluetooth device in the target display list and add the first target Bluetooth device to the third device group.

[0124] In an embodiment of the present disclosure, if it is determined that the HiSyncID of the first target Bluetooth device does not match the HiSyncID of the target Bluetooth device in any device group in the target display list, it means that the first target Bluetooth device and any target Bluetooth device in the target display list are not devices in the same group. At this time, a new device group, i.e., the third device group, is created for the first target Bluetooth device in the target display list, and the first target Bluetooth device is added to the newly created third device group.

[0125] S803: Control the display to display a first group identifier and a connection status identifier corresponding to the first group identifier based on the target display list.

[0126] The first group identifier may be used to identify the first device group in the target display list, and the connection status identifier may be used to represent the connection status of the target Bluetooth device in the first device group.

[0127] According to some embodiments of the device control method, first, a list of paired Bluetooth devices is obtained, wherein the paired Bluetooth device list may include at least one Bluetooth device; then, the paired Bluetooth device list is traversed, and the HiSyncID of the first target Bluetooth device in the paired Bluetooth device list is matched with the HiSyncID of the target Bluetooth device in each device group in the target display list, and when it is determined that the HiSyncID of the first target Bluetooth device successfully matches the HiSyncID of the second target Bluetooth device in the second device group, the first target Bluetooth device is added to the second device group; further, the display is controlled to display the first group identifier and the connection status identifier corresponding to the first group identifier based on the target display list; wherein the first group identifier can be used to identify the first device group in the target display list, and the connection status identifier can be used to characterize the connection status of the target Bluetooth device in the first device group. It can be seen that the embodiment of the present disclosure can add target Bluetooth devices with the same connection status and HiSyncID to the same device group, and display them as the same device group on the display, thereby realizing the display function of Bluetooth devices supporting the ASHA protocol.

[0128] In addition, when it is determined that the HiSyncID of the first target Bluetooth device has not been successfully matched with any target Bluetooth device in the second device group, the embodiment of the present disclosure can create a third device group for the first target Bluetooth device in the target display list and add the first target Bluetooth device group to the third device group, thereby realizing the display function of Bluetooth devices that support the ASHA protocol.

[0129] 13 , as an extension and refinement of the embodiment shown in FIG. 8 , on the basis of steps S801 to S803 shown in FIG. 8 , steps S1301 to S1303 may be further included. According to some embodiments, the device control method may further include the following steps:

[0130] S801: Acquire a list of paired Bluetooth devices; wherein the list of paired Bluetooth devices may include at least one Bluetooth device.

[0131] S802: Add the target Bluetooth devices in the paired Bluetooth device list that have the same connection status and HiSyncID to the same device group in the target display list.

[0132] The target Bluetooth device supports the ASHA protocol, the connection state may include a connected state and an unconnected state, the target display list may include at least a first device group, and the first device group may include at least two target Bluetooth devices.

[0133] S803: Controlling the display to display a first group identifier and a connection status identifier corresponding to the first group identifier based on the target display list, wherein the first group identifier can be used to identify the first device group in the target display list, and the connection status identifier can be used to represent the connection status of the target Bluetooth device in the first device group.

[0134] S1301: In response to a connection state switching message for a third target Bluetooth device, determine the number of target Bluetooth devices in a fourth device group where the third target Bluetooth device is located.

[0135] In the embodiment of the present disclosure, the third target Bluetooth device can be any target Bluetooth device in the target display list. The connection status switching message for the third target Bluetooth device may include a message that the third target Bluetooth device switches from a connected state to an unconnected state, or a message that the third target Bluetooth device switches from an unconnected state to a connected state, etc.

[0136] In the embodiment of the present disclosure, when the display device receives a connection status switching message for the third target Bluetooth device, it first determines the number of target Bluetooth devices in the fourth device group where the third target Bluetooth device is located. For example, the target display list may include device group 1 (target Bluetooth device A, target Bluetooth device B), device group 2 (target Bluetooth device C, target Bluetooth device D), and device group 2 (target Bluetooth device E). When the display device receives a connection status switching message for the target Bluetooth device C, it determines the number of target Bluetooth devices (i.e., 2) in the device group (i.e., device group 2) where the target Bluetooth device C is located.

[0137] S1302: If it is determined that the number of target Bluetooth devices in the fourth device group is greater than 1, the third target Bluetooth device is removed from the fourth device group, and a fifth device group is created for the third target Bluetooth device in the target display list, and the third target Bluetooth device is added to the fifth device group; wherein, the fifth device group can be used to display the device identification of the third target Bluetooth device.

[0138] In the embodiment of the present disclosure, since the connection status of the target Bluetooth devices in the same device group is the same and are displayed as the same device on the display, if it is determined that the number of target Bluetooth devices in the fourth device group is greater than 1, it means that the connection status of the third target Bluetooth device in the fourth device group has changed, while the connection status of other target Bluetooth devices has not changed. Obviously, the third target Bluetooth device and the other target Bluetooth devices in the fourth device group cannot be displayed as the same device. At this time, the third target Bluetooth device needs to be moved to the new device group and displayed based on the new device group.

[0139] Specifically, when the embodiment of the present disclosure determines that the number of target Bluetooth devices in the fourth device group is greater than 1, the third target Bluetooth device is first removed from the fourth device group, and a fifth device group is created for the third target Bluetooth device in the target display list, and the third target Bluetooth device group is added to the fifth device group.

[0140] As shown in Figure 14, it is a processing diagram for updating the connection status of a target Bluetooth device according to some embodiments. When the display device receives a connection status switching message for the target Bluetooth device A, it determines the number of target Bluetooth devices in the fourth device group where the target Bluetooth device A is located. At this time, the number of target Bluetooth devices in the fourth device group is 2, then the target Bluetooth device A is moved out of the fourth device group, and a new device group is created, such as the fifth device group, and then the target Bluetooth device A is moved into the fifth device group. Since the target Bluetooth device A and the target Bluetooth device B are in different device groups, they are displayed as two devices on the display at this time, for example, "Target Bluetooth device A (left) is connected" and "Target Bluetooth device B (right) is not connected".

[0141] As shown in Figure 15, it is a schematic diagram of updating a device management page according to some embodiments. The Bluetooth device A (left and right) displayed on the page shown in Figure 15 (a) indicates that the left ear device and the right ear device of the Bluetooth device A are both in a connected state; when a message is received that the connection state of the left ear device of the Bluetooth device A is switched from a connected state to an unconnected state, since the number of target Bluetooth devices in the Bluetooth device A (left and right) is greater than 1, the left ear device of the Bluetooth device A is removed from the Bluetooth device A (left and right), and the Bluetooth device A (left), that is, the fifth device group, is created for the left ear device of the Bluetooth device A, and the left ear device of the Bluetooth device A is added to the Bluetooth device A (left); as shown in Figure 15 (b), the Bluetooth device A (left) is displayed on the page, indicating that the left ear device of the Bluetooth device A is in an unconnected state. At this time, the right ear device of the Bluetooth device A is still in a connected state, and the device group identifier is updated to the Bluetooth device A (right).

[0142] S1303: If it is determined that the number of target Bluetooth devices in the fourth device group is not greater than 1, update the connection status of the third target Bluetooth device in the fourth device group.

[0143] In the embodiment of the present disclosure, if it is determined that the number of target Bluetooth devices in the fourth device group is not greater than 1, it means that the fourth device group only includes the third target Bluetooth device. At this time, it is only necessary to update the connection status of the third target Bluetooth device in the fourth device group.

[0144] As shown in Figure 16, this is a schematic diagram of updating another device management page according to some embodiments. The Bluetooth device B (left) displayed on the page shown in Figure 16 (a) indicates that the left ear device of the Bluetooth device B is in an unconnected state; when a message is received that the connection state of the left ear device of the Bluetooth device B is switched from an unconnected state to a connected state, since the number of target Bluetooth devices in the Bluetooth device B (left) is not greater than 1, it is only necessary to update the connection state of the left ear device of the Bluetooth device B to a connected state; as shown in Figure 16 (b), this is a schematic diagram of updating the connection state of the left ear device of the Bluetooth device B to a connected state.

[0145] It can be seen that according to the display mode of the Bluetooth device in some embodiments, when a connection status switching message for the third target Bluetooth device is received, the display mode for the third target Bluetooth device can be determined according to the number of devices in the fourth device group where the third target Bluetooth device is located. Specifically, when it is determined that the number in the fourth device group is greater than 1, the third target Bluetooth device is removed from the fourth device group, and a new fifth device group is created and the third target Bluetooth device is added to the fifth device group; when it is determined that the number in the fourth device group is not greater than 1, the connection status of the third target Bluetooth device is updated, thereby realizing the updated display of the connection status of the Bluetooth device.

[0146] In actual applications, for two target Bluetooth devices (i.e., the left ear device and the right ear device) with the same connection status and HiSyncID, if the user wants to unpair the two target Bluetooth devices, etc., it is necessary to perform an operation on both the left ear device and the right ear device to achieve the unpairing of the Bluetooth headsets. The above operation process is relatively cumbersome for the user and affects the user experience.

[0147] To this end, the embodiment of the present disclosure can perform interaction processing corresponding to the target interaction operation on each target Bluetooth device in the first device group when receiving a target interaction operation for any target Bluetooth device in the first device group, thereby enabling a user to operate other devices in the device group to which the device belongs while operating one device, thereby improving the user's interaction experience.

[0148] In the embodiment of the present disclosure, the target interaction operation for any target Bluetooth device may include at least one operation of an unpairing operation, a disconnection operation, and a reconnection operation for the target Bluetooth device.

[0149] For example, assuming that the first device group may include Bluetooth device A, Bluetooth device B and Bluetooth device C, when the display device receives an unpairing operation for Bluetooth device B in the first device group, it performs interactive processing corresponding to the unpairing operation on each target Bluetooth device in the first device group (i.e., Bluetooth device A, Bluetooth device B and Bluetooth device C), thereby achieving that when an unpairing operation is performed on any target Bluetooth device in the device group, all target Bluetooth devices in the device group can be unpaired at the same time, thereby improving the user's interactive experience.

[0150] FIG17 is a schematic diagram of a display processing flow of a Bluetooth device according to some embodiments, which may include the following steps:

[0151] S1701: Obtain a list of Bluetooth devices that the display device has paired with;

[0152] S1702: traverse the list of paired Bluetooth devices;

[0153] S1703: Obtain the connection status of the Bluetooth device;

[0154] S1704: Obtain the device type of the Bluetooth device;

[0155] S1705: Determine whether it is an ASHA device;

[0156] S1706: If it is not an ASHA device, add the device to the target display list; then jump to the subsequent step S1710;

[0157] S1707: If it is an ASHA device, obtain the HiSyncID of the Bluetooth device; otherwise, perform the following steps

[0158] If the Bluetooth device is determined to be a target Bluetooth device that supports the ASHA protocol, the HiSyncID and left and right ear identifiers of the target Bluetooth device are obtained according to the UUID reported by the target Bluetooth device;

[0159] S1708: Determine whether there is a device with the same connection status and HiSyncID;

[0160] S1709: If it exists, add the device to the same device group;

[0161] It is determined whether there is a Bluetooth device in the target display list whose connection status and HiSyncID are the same as those of the target Bluetooth device. If so, the target Bluetooth device is added to the same device group.

[0162] S1710: Determine whether all Bluetooth devices have been processed;

[0163] S1711: If all processing has been completed, display each device group based on the target display list; otherwise, jump to the aforementioned step S1702 and re-traverse the Bluetooth device list to perform subsequent steps S1703 to S1711 on the devices to be processed in the list.

[0164] Furthermore, considering that users often need to adjust the volume of their Bluetooth devices, current device control methods mostly involve using physical buttons on the Bluetooth device to control the volume, or adjusting the volume of the audio data of the Bluetooth device through the audio playback device. However, currently, adjusting the volume of the Bluetooth device through the audio playback device can only adjust the volume of the left and right Bluetooth devices at the same time, and cannot adjust the volume of the left or right Bluetooth device separately.

[0165] Based on this, the embodiments of the present disclosure further provide a control process of a Bluetooth device as shown in FIG18 . The execution subject of this process may be the display device 200 in the embodiment shown in FIG1 . FIG18 is another flow chart of a method for controlling a Bluetooth device according to some embodiments, which may include the following steps:

[0166] S1801: In response to a volume adjustment operation on a target Bluetooth device, obtaining a MAC address of the target Bluetooth device and adjusted volume data corresponding to the volume adjustment operation; wherein the target Bluetooth device is a left ear Bluetooth device or a right ear Bluetooth device;

[0167] In some embodiments, the target Bluetooth device may be a left ear Bluetooth device or a right ear Bluetooth device in a pair of Bluetooth devices. A volume bar for the left ear Bluetooth device and a volume bar for the right ear Bluetooth device may be displayed on the display of the display device; upon receiving a trigger operation for the volume bar of the left ear Bluetooth device, the MAC address of the left ear Bluetooth device and the adjusted volume data corresponding to the volume adjustment operation are obtained; for example, upon receiving a trigger operation for the volume bar of the right ear Bluetooth device, the MAC address of the right ear Bluetooth device and the adjusted volume data corresponding to the volume adjustment operation are obtained.

[0168] In some embodiments, the display device responds to a volume adjustment operation on a target Bluetooth device, which may include: the display device receives a user's volume adjustment operation on the target Bluetooth device through a remote control. For example, the user operates the "volume +" button on the remote control for the left ear Bluetooth device, and the remote control sends an operation to increase the volume of the left ear Bluetooth device by 1 to the display device. Accordingly, the display device responds to the operation of increasing the volume by 1 on the left ear Bluetooth device, obtains the MAC address of the left ear Bluetooth device and the adjusted volume data corresponding to the operation of increasing the volume by 1.

[0169] For example, if the remote control receives the voice input of "subtract 1 from the volume value of the right ear Bluetooth device" through the voice receiving component, the remote control sends the operation of subtracting 1 from the volume value of the right ear Bluetooth device to the display device. Accordingly, the display device responds to the operation of subtracting 1 from the volume value of the right ear Bluetooth device, obtains the MAC address of the right ear Bluetooth device and the adjusted volume data corresponding to the operation of subtracting 1 from the volume value.

[0170] In the embodiment of the present disclosure, when a display device receives a volume adjustment operation for a target Bluetooth device, it obtains the MAC address of the target Bluetooth device. The MAC address (Media Access Control Address), also known as the physical address or hardware address, is burned into the device's chip by the device manufacturer during production and can be used to uniquely identify the device.

[0171] For example, assuming that the current volume data of the left ear Bluetooth device is 100, when the display device receives an operation to reduce the volume by 10 for the left ear Bluetooth device, it obtains the MAC address of the left ear Bluetooth device and the adjusted volume data corresponding to the volume key 10 operation, that is, 90 is used as the adjusted volume data.

[0172] S1802: Send the MAC address and the adjusted volume data to the audio module, and control the audio module to send the MAC address and the adjusted volume data to the Bluetooth protocol stack through the Bluetooth interface;

[0173] In the embodiment of the present disclosure, after obtaining the MAC address of the target Bluetooth device and the adjusted volume data corresponding to the volume adjustment operation, the display device sends the MAC address and the adjusted volume data to the audio module, and controls the audio module to send the MAC address and the adjusted volume data to the Bluetooth protocol stack of the display device through the Bluetooth interface.

[0174] The Bluetooth protocol stack refers to a protocol stack that includes traditional Bluetooth and low-power Bluetooth. The Bluetooth protocol stack can adjust the audio gain of the audio stream according to the received volume data to control the volume of the audio stream.

[0175] In some embodiments, after the display device sends the MAC address and adjusted volume data of the target Bluetooth device to the audio module, it can also control the audio module to store the corresponding MAC address and adjusted volume data to the data storage module, so that the display device can display the adjusted volume data of the target Bluetooth device based on the correspondence between the MAC address and the adjusted volume data in the data storage module.

[0176] S1803: Control the Bluetooth protocol stack to adjust the audio gain of the target audio stream according to the adjusted volume data; wherein the target audio stream is the audio stream output to the target Bluetooth device corresponding to the MAC address;

[0177] In the embodiment of the present disclosure, after controlling the audio module to send the MAC address and adjusted volume data to the Bluetooth protocol stack through the Bluetooth interface, the display device can also control the Bluetooth protocol stack to adjust the audio gain of the target audio stream according to the adjusted volume data.

[0178] Among them, audio gain can be used to represent the audio playback capability of a Bluetooth device. Adjusting the audio gain of the audio stream sent to the Bluetooth device can change the volume of the Bluetooth device. In practical applications, gain can be used to represent the ratio of audio input to audio output.

[0179] In some embodiments, upon receiving the target audio stream from the display device, the target Bluetooth device can play the target audio stream.

[0180] According to some embodiments of the control method of the Bluetooth device, first, in response to the volume adjustment operation on the target Bluetooth device, the MAC address of the target Bluetooth device and the adjusted volume data corresponding to the volume adjustment operation are obtained; wherein the target Bluetooth device belongs to the left ear Bluetooth device or the right ear Bluetooth device; then, the MAC address and the adjusted volume data are sent to the audio module, and the audio module is controlled to send the MAC address and the adjusted volume data to the Bluetooth protocol stack through the Bluetooth interface; finally, the Bluetooth protocol stack is controlled to adjust the audio gain of the target audio stream according to the adjusted volume data; wherein the target audio stream is the audio stream output to the target Bluetooth device corresponding to the MAC address. It can be seen that the embodiment of the present disclosure can realize the independent adjustment of the volume of the left ear Bluetooth device or the right ear Bluetooth device through the display device, that is, it realizes the function of independently controlling the volume of the left and right ears of the Bluetooth device.

[0181] 19 , as an extension and refinement of the embodiment shown in FIG. 18 , based on steps S1801 to S1803 shown in FIG. 18 , before step S1801 (in response to a volume adjustment operation on a target Bluetooth device, obtaining the MAC address of the target Bluetooth device and the adjusted volume data corresponding to the volume adjustment operation), the method for controlling a Bluetooth device according to some embodiments may further include the following steps:

[0182] S1901: In response to a pairing request triggered for the target Bluetooth device, establish a Bluetooth connection with the target Bluetooth device;

[0183] In an embodiment of the present disclosure, before responding to a volume adjustment operation on the target Bluetooth device and obtaining the MAC address of the target Bluetooth device and the adjusted volume data corresponding to the volume adjustment operation, a Bluetooth connection can also be established with the target Bluetooth device in response to a pairing request triggered for the target Bluetooth device.

[0184] In some embodiments, the display device may further control the Bluetooth module to scan surrounding Bluetooth devices before establishing a Bluetooth connection with the target Bluetooth device in response to a pairing request triggered for the target Bluetooth device.

[0185] In practice, when a display device scans for nearby Bluetooth devices, different icons are displayed for different Bluetooth devices. For example, if the scanned Bluetooth device is a Bluetooth keyboard, a keyboard icon is displayed for the Bluetooth keyboard. If the scanned Bluetooth device is a Bluetooth controller, a controller icon is displayed for the Bluetooth controller. The specific icon displayed is determined by the device type information of the scanned Bluetooth device, that is, the COD information (Class of Device) of the Bluetooth device.

[0186] In some embodiments, when the display device controls the Bluetooth module to scan for surrounding Bluetooth devices, if a Bluetooth device is scanned, a preset identifier for the Bluetooth device, such as a left ear hearing aid icon or a right ear hearing aid icon, is displayed.

It can be seen that the embodiment of the present disclosure can realize the independent adjustment of the volume of the left ear Bluetooth device or the right ear Bluetooth device through the display device.

[0220] 21 , as an expansion and refinement of the embodiment shown in FIG19 , based on steps S1901 to S1903 and steps S1801 to S1803 shown in FIG19 , before step S1901 (establishing a Bluetooth connection with the target Bluetooth device in response to a pairing request triggered for the target Bluetooth device), and replacing step S1902 (obtaining the syncid and left and right ear information of the target Bluetooth device after determining that the Bluetooth connection is successful) with step S2102, the method for controlling a Bluetooth device according to some embodiments may further include the following steps:

[0221] S2101: Control the Bluetooth module to scan Bluetooth devices and obtain the MAC address of the scanned Bluetooth devices; wherein the scanned Bluetooth devices may include the target Bluetooth device;

[0222] In some embodiments, when entering the device management page, the display device automatically controls the Bluetooth module to scan nearby Bluetooth devices, and during the scanning process, obtains the MAC address of the scanned Bluetooth device, wherein the target Bluetooth device belongs to the scanned Bluetooth device.

[0223] In some embodiments, while the display device controls the Bluetooth module to scan for nearby Bluetooth devices, it can also control the display to display the scanned Bluetooth devices. The scanned devices may include Bluetooth-enabled audio receiving devices, such as headphones, speakers, hearing aids, and other devices, and may also include Bluetooth-enabled mice, keyboards, electronic pens, and other devices.

[0224] The Bluetooth module can be used to exchange information with other devices supporting the Bluetooth function through the Bluetooth protocol. For example, the display device can scan other devices supporting the Bluetooth function through the Bluetooth module.

[0225] S1901: In response to a pairing request triggered for the target Bluetooth device, establish a Bluetooth connection with the target Bluetooth device.

[0226] In some embodiments, during the process of controlling the display to display the scanned Bluetooth devices, the display device may also establish a Bluetooth connection with the target Bluetooth device in response to a pairing request triggered for the target Bluetooth device among the scanned Bluetooth devices;

[0227] S2102: After determining that the Bluetooth connection is successful, obtain capabilities information and syncid reported by the target Bluetooth device based on the MAC address of the target Bluetooth device; wherein the capabilities information may include single and double ear information and left and right ear information;

[0228] In the disclosed embodiment, after determining that a Bluetooth connection has been successfully established with a target Bluetooth device, the display device can obtain the capabilities information and SyncID reported by the target Bluetooth device based on the MAC address of the target Bluetooth device obtained during the scanning process. The SyncID can be used to identify the binding relationship between the target Bluetooth device and other Bluetooth devices.

[0229] In the embodiments of the present disclosure, the capabilities information reported by the target Bluetooth device may include single-ear and double-ear information and left-right ear information of the target Bluetooth device. The single-ear and double-ear information can be used to identify whether the target Bluetooth device is a single-ear device or a double-ear device, and the left-right ear information can be used to identify whether the target Bluetooth device is a left-ear Bluetooth device or a right-ear Bluetooth device.

[0230] For example, assuming that the syncid of target Bluetooth device A is 001 and the target Bluetooth device is a left ear Bluetooth device, the Bluetooth device that has a binding relationship with the target Bluetooth device A may be Bluetooth device B that is a right ear Bluetooth device and has a syncid of 001.

[0231] It should be noted that, in the embodiment of the present disclosure, the display device obtains the MAC address of the target Bluetooth device while controlling the Bluetooth module to scan the Bluetooth device, and obtains the SyncID of the target Bluetooth device after successfully establishing a Bluetooth connection with the target Bluetooth device.

[0232] S1903: storing the corresponding MAC address of the target Bluetooth device, the syncid, and the left and right ear information in a data storage module;

[0233] In the disclosed embodiment, the display device obtains the capabilities information reported by the target Bluetooth device based on the MAC address of the target Bluetooth device, determines the correspondence between the MAC address, SYNCID, and left and right ear information of the target Bluetooth device, and stores the corresponding MAC address, SYNCID, and left and right ear information of the target Bluetooth device in a data storage module. Subsequently, when the MAC address of the target Bluetooth device is obtained, the SYNCID and left and right ear information of the target Bluetooth device can be obtained from the data storage module based on the above correspondence.

[0234] In some embodiments, after the display device stores the MAC address, syncid, and left and right ear information of the corresponding target Bluetooth device in the data storage module, it can also obtain the syncid and left and right ear information corresponding to the MAC address of the target Bluetooth device from the data storage module in response to a display trigger operation of the volume adjustment page corresponding to the target Bluetooth device; further, based on the syncid and left and right ear information, control the display to display the target device information for the target Bluetooth device on the volume adjustment page.

[0235] In an embodiment of the present disclosure, the display triggering operation of the volume adjustment page corresponding to the target Bluetooth device may include: in the process of displaying successfully connected Bluetooth devices on the device management page, in response to a click operation on the target Bluetooth device in the Bluetooth device, controlling the display to display the volume adjustment page corresponding to the target Bluetooth device.

[0236] In actual applications, since the MAC address of a device can be used to uniquely identify the device, when a display operation of the volume adjustment page corresponding to the target Bluetooth device is received, the syncid and left and right ear information corresponding to the MAC address of the target Bluetooth device can be obtained from the data storage module, so that the target device information of the target Bluetooth device can be displayed on the volume adjustment page based on the syncid and left and right ear information.

[0237] Among them, the target device information can be used to describe the device information of the target Bluetooth device. For example, the target device information may include a Bluetooth device identifier and left and right ear information. Specifically, the target device identifier can be used to identify the binding relationship to which the target Bluetooth device belongs, and the left and right ear information can be used to identify whether the target Bluetooth device belongs to a left ear Bluetooth device or a right ear Bluetooth device.

[0238] After obtaining the syncid and left and right ear information corresponding to the MAC address of the target Bluetooth device, the display is controlled to display the target device information for the target Bluetooth device on the volume adjustment page based on the syncid and left and right ear information, so that the user can understand which pair of Bluetooth devices, the left ear Bluetooth device or the right ear Bluetooth device, is to be adjusted based on the target device information.

[0239] In some embodiments, a volume bar corresponding to the target Bluetooth device may also be displayed on the volume adjustment page corresponding to the target Bluetooth device, and the volume bar may be used to indicate the current volume data of the target Bluetooth device. In addition, after receiving a volume adjustment operation for the target Bluetooth device, the display device may also control the volume bar to display the adjusted volume data corresponding to the volume adjustment operation.

[0240] As shown in Figure 22, this is a schematic diagram of a volume adjustment page according to some embodiments, wherein the page displays target device information corresponding to the target Bluetooth device, such as the left ear volume adjustment of Bluetooth device 1, and the right ear volume adjustment of Bluetooth device 1, and can also display volume bars corresponding to the target Bluetooth device, such as the left ear volume bar of Bluetooth device 1, and the right ear volume bar of Bluetooth device 1.

[0241] S1801: In response to a volume adjustment operation on a target Bluetooth device, obtaining a MAC address of the target Bluetooth device and adjusted volume data corresponding to the volume adjustment operation; wherein the target Bluetooth device is a left ear Bluetooth device or a right ear Bluetooth device;

[0242] S1802: Send the MAC address and the adjusted volume data to the audio module, and control the audio module to send the MAC address and the adjusted volume data to the Bluetooth protocol stack through the Bluetooth interface;

[0243] S1803: Control the Bluetooth protocol stack to adjust the audio gain of the target audio stream according to the adjusted volume data; wherein the target audio stream is the audio stream output to the target Bluetooth device corresponding to the MAC address.

[0244] According to some embodiments, a method for controlling a Bluetooth device includes: first, controlling a Bluetooth module to scan Bluetooth devices and obtaining MAC addresses of the scanned Bluetooth devices; wherein the scanned Bluetooth devices may include a target Bluetooth device; establishing a Bluetooth connection with the target Bluetooth device in response to a pairing request triggered for the target Bluetooth device; after determining that the Bluetooth connection is successful, obtaining capabilities information and SyncID reported by the target Bluetooth device based on the MAC address of the target Bluetooth device; wherein the capabilities information may include single-ear and double-ear information and left-ear and right-ear information; then, storing the corresponding MAC address, SyncID, and left-ear and right-ear information of the target Bluetooth device in a data storage module; in response to a volume adjustment operation on the target Bluetooth device, obtaining the MAC address of the target Bluetooth device and adjusted volume data corresponding to the volume adjustment operation; wherein the target Bluetooth device is a left-ear Bluetooth device or a right-ear Bluetooth device; then, sending the MAC address and adjusted volume data to an audio module, and controlling the audio module to send the MAC address and adjusted volume data to a Bluetooth protocol stack via a Bluetooth interface; further, controlling the Bluetooth protocol stack to adjust the audio gain of a target audio stream according to the adjusted volume data; wherein the target audio stream is the audio stream output to the target Bluetooth device corresponding to the MAC address. It can be seen that the embodiment of the present disclosure can realize independent adjustment of the volume of the left ear Bluetooth device or the right ear Bluetooth device through the display device.

[0245] In some embodiments, when the display device receives a reconnection message from a target Bluetooth device, it first parses the reconnection message to obtain the MAC address of the target Bluetooth device and sends the MAC address to the audio module. It then controls the audio module to obtain the latest volume data corresponding to the MAC address of the target Bluetooth device from the data storage module and sends the MAC address and the latest volume data to the Bluetooth protocol stack. Furthermore, the Bluetooth protocol stack is controlled to output an audio stream to the target Bluetooth device corresponding to the MAC address based on the latest volume data.

[0246] In some embodiments, after receiving the reconnection message of the target Bluetooth device and before parsing the MAC address of the target Bluetooth device from the reconnection message, the display device may further monitor the reconnection message of the Bluetooth device in response to restarting the display device.

[0247] In actual applications, when the display device is restarted, it will detect whether there is a Bluetooth device that requests to re-establish the Bluetooth connection. The specific implementation is to monitor the reconnection message of the Bluetooth device.

[0248] When the display device is monitoring the reconnection message of the Bluetooth device, if the display device has previously established a Bluetooth connection with the target Bluetooth device and the target Bluetooth device is sending a reconnection message to the display device, the MAC address of the target Bluetooth device can be parsed from the reconnection message after receiving the reconnection message from the target Bluetooth device.

[0249] Furthermore, the control audio module obtains the latest volume data corresponding to the MAC address from the data storage module, and sends the MAC address and the latest volume data to the Bluetooth protocol stack. Wherein, the latest volume data is the most recent volume data or the previous volume data stored in the data storage module.

[0250] It can be seen that the display device in the embodiment of the present disclosure can monitor the reconnection message of the target Bluetooth device when restarting, and parse the MAC address of the target Bluetooth device from the reconnection message, and then obtain the latest volume data based on the MAC address, and control the Bluetooth protocol stack to output the audio stream to the target Bluetooth device based on the latest volume data, thereby realizing the function of automatically synchronizing the latest volume data to the target Bluetooth device when restarting.

[0251] In some embodiments, after the display device sends the MAC address of the target Bluetooth device to the audio module, it can also control the audio module to obtain the SyncID corresponding to the MAC address from the data storage module, and determine the first Bluetooth device corresponding to the SyncID based on the historical data in the memory. The first Bluetooth device is a Bluetooth device that has a binding relationship with the target Bluetooth device, that is, the SyncID of the first Bluetooth device is the same as the SyncID of the target Bluetooth device.

[0252] As shown in Figure 22, assuming that the target Bluetooth device displayed on the volume adjustment page is the left ear Bluetooth device of Bluetooth device 1, after the display device sends the MAC address of the left ear Bluetooth device of Bluetooth device 1 to the audio module, it controls the audio module to obtain the syncid corresponding to the MAC address from the data storage module, and then determines the first Bluetooth device that has a binding relationship with the left ear Bluetooth device of Bluetooth device 1, that is, the right ear Bluetooth device of Bluetooth device 1.

[0253] In actual applications, the scenario in which the display device receives the reconnection message of the target Bluetooth device may include: after the display device establishes a Bluetooth connection with the target Bluetooth device and obtains the syncid and left and right ear information of the target Bluetooth device, if the display device is powered on and restarted, the latest volume data saved in the data storage module can be synchronized to the target Bluetooth device, thereby realizing independent control of the volume of the target Bluetooth device.

[0254] FIG23 is a schematic diagram of a scenario in which audio data is synchronized after a display device restarts according to some embodiments. Upon receiving a reconnection message from a target Bluetooth device, the Bluetooth application module in the display device parses the message to obtain the MAC address of the target Bluetooth device and then sends the MAC address to the audio module. The module then controls the acquisition of the latest volume data corresponding to the MAC address from the data storage module and sends the MAC address and the latest volume data to the Bluetooth application module. The Bluetooth application module then sends the MAC address and the latest volume data to the Bluetooth protocol stack. Finally, the Bluetooth protocol stack is controlled to output an audio stream to the target Bluetooth device corresponding to the MAC address based on the latest volume data.

[0255] Through the above process, a device control method provided by an embodiment of the present disclosure can add target Bluetooth devices with the same connection status and HiSyncID to the same device group and display them as the same device group on the display, thereby realizing the display function for Bluetooth devices that support the ASHA protocol. Furthermore, it is also possible to independently adjust the volume of the left ear Bluetooth device or the right ear Bluetooth device through the display device, that is, to realize the function of independently controlling the volume of the left and right ears of the Bluetooth device.

[0256] Figure 24 is a schematic diagram of the structure of an electronic device according to some embodiments, which may be the display device, control terminal, or audio receiving device described above. As shown in Figure 24, the electronic device may include: a processor 2401, a memory 2402, and a computer program stored in the memory 2402 and executable on the processor 2401. When the computer program is executed by the processor 2401, it implements the following method in the above-mentioned method embodiment: a device control method executed by a display device.
