Currently, the display device may be connected to the first audio device through bluetooth, for example, as shown in fig. 2, the first audio device may be a bluetooth speaker, so that the audio of the display device may be played through the first audio device, so that a user may feel that the audio effect is better when using the display device, that is, at this time, the bluetooth on the display device is in a source mode (source mode), and the bluetooth on the first audio device is in a sink mode (sink mode).

It should be noted that, when bluetooth is in the source mode, the device corresponding to bluetooth is the generation site of the data source. Illustratively, when bluetooth is in source mode on the display device, the display device generates data for the source of the data, i.e., the display device. At this time, the display device is connected with the first audio device, and finally the audio is played through the first audio device. The bluetooth is in the sink mode, which means that the device corresponding to the bluetooth is the destination of the data source. Illustratively, when bluetooth is in the sink mode on the first audio device, the first audio device is the destination of the data source, i.e., receives the data sent by the display device, and the first audio device plays the data.

In order to enrich the functions of the display device, the bluetooth on the display device in the embodiment of the present application can be in the source mode and the sink mode. Bluetooth on the display device can be switched from source mode to sink mode or from sink mode to source mode, as desired.

In order to enrich the functional problem of the display device, an embodiment of the present application provides a method for adjusting a bluetooth mode on the display device, as shown in fig. 3, the method includes:

s101, responding to the situation that the Bluetooth on the display equipment is set to be in a sink mode, and judging whether the first audio equipment is connected with the display equipment or not.

S102, if the display device is connected with the first audio device through the Bluetooth, the connection between the first audio device and the display device is disconnected, the first audio device is used for playing first audio data sent by the display device, the display device is set to be in a state capable of being found by the second audio device, and the second audio device is used for sending second audio data to the display device so that the display device can play the second audio device.

In the embodiment of the application, after the Bluetooth on the display device is set to be in the sink mode, the display device is set to be in a state of being discovered by the second audio device, so that the second audio device can search the display device and is connected with the display device. Illustratively, the second audio device may be a mobile terminal, as shown in fig. 4. The display equipment is connected with the mobile terminal and plays second audio data sent by the mobile terminal.

It should be noted that, in the embodiment of the present application, a manner of setting the bluetooth mode on the display device includes: entering the special application, wherein the Bluetooth on the display device is set to be in a signal sink mode, and exiting the special application, the Bluetooth on the display device is set to be in a signal source mode.

In addition, a bluetooth setting page of the display device may be entered to set a bluetooth mode on the display device, for example, as shown in fig. 5, a bluetooth connection mode entry item 41 is displayed on the interface, and the user may select the bluetooth connection mode entry item 41 by moving the selector 42 through the control device, at which time the page jumps to fig. 6. The selector may move the position of the selector in the GUI and select any of the items by input from a user operating the control. For example, the selector 42 indicates that the bluetooth connection mode entry item 41 is selected.

The form of identification of the selector is often diversified. For example, the position of the focus object 42 may be identified by changing the border line, size, color, transparency, and outline of the text or image of the focused item and/or the font, etc. as in fig. 5, and may be implemented or identified by setting the background color of the item.

The interface in fig. 6 shows a hyphen item 43 and a hyphen item 44. And when the user selects the item of connecting the mobile phone, setting the Bluetooth mode on the display equipment to be the information sink mode. And when the user selects the continuous sound item, setting the Bluetooth module on the display equipment as the information source mode.

In some embodiments, the method further comprises: s103, in response to the setting of the Bluetooth on the display device to be in a sink mode, if the display device is not connected with the first audio device, the display device is directly set to be in a state of being discoverable by the second audio device.

In some embodiments, the step of disconnecting the connection between the first audio device and the display device comprises: and after the protocol between the first audio equipment and the display equipment is disconnected, disconnecting an Asynchronous Connectionless (ACL) link between the first audio equipment and the display equipment.

Due to the limitation of bluetooth resources, only 1 connection of ACL links can be maintained for BR/EDR type (classic bluetooth) devices, otherwise the resources are busy and various types of errors occur, so the ACL link between the first audio device and the display device needs to be completely disconnected. It should be noted that the step of disconnecting the connection between the first audio device and the display device is that the framework layer disconnects the protocol of A2dp of the sink mode first, and after the protocol is disconnected, the ACL link is disconnected next.

In some embodiments, the method further comprises: and responding to the setting of Bluetooth on the display equipment as an information source mode, if the display equipment is connected with second audio equipment through Bluetooth, disconnecting the second audio equipment from the display equipment, and detecting whether first audio equipment exists in a pairing list, wherein the pairing list is used for storing the history of audio equipment successfully paired with the Bluetooth on the display equipment, and the audio equipment comprises the first audio equipment and/or the second audio equipment.

The disconnecting of the mobile terminal from the display device is substantially the same as the disconnecting of the first audio device from the display device, except that the framework layer no longer disconnects the A2dp protocol for the sink mode, but disconnects the A2dp protocol for the source mode.

Automatically initiating a loopback with a first audio device if the first audio device is present in the pairing list; if the loopback is successful, the display device is set to a non-discoverable state by the second audio device. In the embodiment of the application, for the convenience of the user, when the first audio equipment exists in the pairing list, the first audio equipment is automatically connected back to the first audio equipment.

The embodiment of the application can smoothly complete the mode switching of the display device connected with the first audio device through the Bluetooth and the display device connected with the second audio device through the Bluetooth, and achieves the purpose of successful reconnection of the devices after the mode switching.

In some embodiments, the method further comprises: and controlling the source mode and the sink mode of the Bluetooth on the display device to coexist in the Bluetooth protocol stack in response to the display device being powered on.

It should be noted that the inventor finds that, when the bluetooth mode on the display device is switched, the switching failure and other problems often occur. Through a lot of research, the reason is that when switching, the involved logic is too much, but the Bluetooth bottom layer resource is limited, and a plurality of logics are executed simultaneously. The coexistence of the source mode and the sink mode of the bluetooth on the display device in the embodiment of the present application can be realized in a bluetooth protocol stack, and this part is realized by software codes. The control is carried out by the macro switch, and for a Bluetooth protocol stack, a source mode and a sink mode belong to the Profile (protocol) of A2DP (Advanced Audio Distribution Profile Bluetooth Audio transmission model agreement), and the roles of the protocols are different, so that the basic logic is completely initialized in the code. And the frame layer calls an initialization information source mode module (init _ src) and simultaneously calls an initialization information sink mode module (init _ sink), so that normal initialization of the two modes is ensured.

In some embodiments, after controlling the coexistence of the source mode and the sink mode of bluetooth on the display device in the bluetooth protocol stack, the method further comprises:

detecting whether a first audio device exists in the pairing list;

automatically initiate a loopback connection with the first audio device if the first audio device is present in the pairing list. The method and the device for switching the audio devices can reduce the logic complexity during mode switching, and can start the display device to initiate the connection back with the first audio device, so that the user can use the audio devices conveniently.

Setting the display device to a non-discoverable state by a second audio device if the reconnect with the first audio device is successful. When the display device is set to be in the non-discoverable state, the display device cannot be searched by the second audio device. Therefore, the situation that the second audio equipment searches the display equipment can be avoided, the information that the second audio equipment needs to be paired is displayed on the display equipment in a pop-up window mode, and the use experience of a user when the display equipment is connected with the first audio equipment is improved. Except that the display device is successfully connected with the first audio device, under the other conditions, the display device is in a discoverable state, and the display device can be searched by the second audio device. It is noted that in the embodiments of the present application, bluetooth must be in sink mode on the display device if it is desired that the display device can receive audio from the second audio device. So, although the display device is discoverable after power-on, the display device and the second audio device cannot be connected.
