In some embodiments, in a bluetooth communication system including a display device and a bluetooth device external to the display device, the display device is a bluetooth master device, the external bluetooth device is a bluetooth slave device, and when the bluetooth slave device is a bluetooth audio device, the display device outputs audio data to the bluetooth audio device for playing.

In other embodiments, in a bluetooth communication system including a display device and other bluetooth enabled smart devices, the display device is a bluetooth slave device, and the other smart device is a bluetooth master device, and the smart device may output audio data to the display device for playing.

It should be noted that, in the present application, the processing tasks that need to occupy the bluetooth communication resource include, but are not limited to, the following: scanning tasks, pairing tasks, connection tasks, audio data transmission tasks, networking configuration and control of the mesh device and the like.

Based on the limitation of bluetooth communication resources, to avoid resource preemption, improve the success rate of device pairing and connection, and reduce bluetooth audio jamming, so as to implement reasonable scheduling and effective use of bluetooth communication resources, in the display device provided in the embodiment of the present application, the controller is configured to execute the method steps shown in fig. 15, and in particular, when implementing, a control center may be configured in a framework layer, and the control center executes the method steps shown in fig. 15. As shown in fig. 15, includes:

step 151, when receiving an operation request of the application to the bluetooth module, acquiring a state of the bluetooth module, where the state of the bluetooth module includes a working state and an idle state.

The application layer includes several applications, such as a system setup application, a music playing application, a game application, etc., that can operate the bluetooth module to invoke bluetooth communication resources. In specific implementation, the application receives user operations input by a user on the user interface shown in fig. 9-13 by using the control device, generates an operation request and sends the operation request to the framework layer, wherein the operation request may include operation registration information, interface protocol information, and the like.

And when the framework layer receives an operation request of the application to the Bluetooth module, acquiring the state of the Bluetooth module. The states of the bluetooth module include an active state and an idle state, and the bluetooth module in the active state executes at least one current processing task.

In some embodiments, the framework layer records the status of the bluetooth module by recording commands to the bluetooth module and/or reported data from the bluetooth module.

In other embodiments, the bluetooth module may be configured to report its status to the framework layer periodically.

Step 152, judging whether the bluetooth module is in the working state, if so, executing step 153, and if not, executing step 160.

Step 153, if the bluetooth module is in working state, determining the priority of the target processing task corresponding to the operation request and the priority of the current processing task of the bluetooth module.

In this embodiment, the processing tasks to be executed by the bluetooth module are classified in advance to obtain a plurality of task categories, including but not limited to a scanning task, a pairing task, a connection task, a mesh-related task, a remote controller voice task, and an audio data transmission task. Further, the processing tasks corresponding to different operation requests may belong to different task categories, for example, a scan operation based request corresponds to a scan class task and a pairing operation based request corresponds to a pairing class task.

In this embodiment, different priorities may be set for different task categories according to requirements, for example, different priorities may be set for different task categories according to execution frequency and/or calling manner and/or called application.

In some embodiments, different classes of processing tasks may preset the same level of priority.

Illustratively, since the pairing class processing task, the connection class processing task and the mesh-related processing task are not performed frequently and generally require a user to operate and initiate on a user interface, the priority of the three classes of processing tasks may be set to be the highest; for the voice task of the remote controller, because the user is required to actively press the voice key on the remote controller for triggering, the operations of inquiry, application switching and the like can be conveniently carried out by the user through the voice of the remote controller, and the use frequency is higher, the priority of the voice task of the remote controller can be set to be higher in order to quickly respond to the voice input of the user; because the scanning action is a background running process, the scanning action is not easy to be sensed by a user, and if waiting or delaying occurs, the user can not be experienced, so that the priority of the scanning processing task can be set to be lower; finally, since audio transmission occupies a large bandwidth resource, it is preferable that the audio transmission is suspended or the audio sampling rate is reduced when other processing tasks need to be performed, so that the priority of the audio data transmission type processing task can be set to be the lowest.

In some embodiments, the interface protocols invoked by the operation requests corresponding to different classes of processing tasks are different, wherein the different interface protocols are used for invoking different methods to enable the bluetooth module to implement different bluetooth functions. For example, the scan operation request calls an interface protocol that is different from the interface protocol called by the pair operation request. Therefore, the task types can be distinguished according to the interface protocols called by the operation requests corresponding to the target processing task and the current processing task.

In some embodiments, the operation requests corresponding to different processing tasks are sent to the framework layer by different applications, for example, the transmission of audio data is initiated by the application currently playing audio. Therefore, the task categories can be distinguished according to the initiator of the operation request corresponding to the target processing task and the current processing task.

It should be noted that there are many ways to determine the task category according to the operation request, and details are not described here.

Based on this, in this embodiment, the task categories of the target processing task and the current processing task may be obtained according to an interface protocol called by the operation request corresponding to the target processing task and the current processing task or an application initiating the operation request; and determining the priority of each task according to the task category of each task, wherein different task categories are preset with the same or different priorities.

In some embodiments, before determining the priority of the target processing task and the priority of the current processing task, it is determined whether the bluetooth communication resource needs to be coordinated, for example, it may be determined whether the bluetooth communication resource needs to be coordinated according to parameters such as resource occupancy rate, packet loss rate, or transmission rate, and in case that it is determined that the bluetooth communication resource needs to be coordinated, the step of determining the priorities of the target processing task and the current processing task is performed.

Step 154, determine if the priority of the target processing task is higher than the priority of the current processing task, if yes, go to step 155, if no, go to step 158 or step 159.

And 155, if the priority of the target processing task is higher than that of the current processing task, controlling the Bluetooth module to suspend executing the current processing task and executing the target processing task.

During specific implementation, a pause instruction can be generated according to the current processing task and sent to the Bluetooth module so that the Bluetooth module pauses execution of the current processing task; and generating a control instruction according to the operation request and sending the control instruction to the Bluetooth module so that the Bluetooth module executes the target processing task.

Optionally, after the current processing task is suspended, an interface prompt including corresponding prompt information is generated, and the interface prompt is controlled to be displayed on a user interface presented by the display to prompt a user that the current processing task is suspended. For example, as shown in fig. 16, if the audio data transmission is paused, a prompt containing "the current play is paused" is generated.

In step 156, it is monitored whether the bluetooth module has completed executing the target processing task;

in step 157, when the bluetooth module finishes executing the target processing task, the bluetooth module is controlled to resume executing the suspended processing task.

In some embodiments, the priority of the target processing task is the same as the priority of the current processing task. In other embodiments, the priority of the target processing task is lower than the priority of the current processing task.

If the priority of the target processing task is equal to the priority of the current processing task, the bluetooth module is controlled to execute the target processing task and the current processing task in parallel in step 158.

During specific implementation, a control instruction is generated according to an operation request; and sending the control instruction to the Bluetooth module so that the Bluetooth module executes the target processing task and the current processing task corresponding to the control instruction in parallel according to the control instruction.

If the priority of the target processing task is lower than the priority of the current processing task, the operation request is denied in step 159.

Optionally, after the operation request is rejected, an interface prompt including corresponding prompt information is generated, and the interface prompt is controlled to be displayed on a user interface presented by the display, so as to prompt that the user cannot execute the current operation. For example, as shown in fig. 17, after the scanning operation by the user is rejected, a prompt including "scan cannot be currently performed, please retry later" is generated.

In step 160, if the bluetooth module is in the idle state, the bluetooth module is controlled to perform the target processing task. Specifically, a control instruction is generated according to the operation request; and sending the control instruction to the Bluetooth module so that the Bluetooth module executes the target processing task corresponding to the control instruction according to the control instruction.
