Step S602, after the display device determines that the display device is disconnected with the Bluetooth device abnormally through the state monitoring module, the key monitoring module is started.

Specifically, after the display device and the Bluetooth device are connected, the state monitoring module can be started, the display device can monitor the connection state between the display device and the Bluetooth device through the state monitoring module, and if the display device detects that the display device is disconnected from the Bluetooth device through the state monitoring module, the key monitoring module can be started.

In the embodiment of the present application, the abnormal disconnection is any one of other disconnection manners other than the manual disconnection indicated by the user.

In step S603, the display device sends a key monitoring request to the bluetooth device through the key monitoring module.

In step S604, the display device does not receive the key monitoring information sent by the bluetooth device within the first set duration, and takes the first connection mode of the preset plurality of connection modes as the target connection mode.

In step S605, the display device scans the connection signal sent by the bluetooth device according to the scanning period included in the first connection mode.

In this embodiment of the present application, the scanning period may include a scanning duration and an interval duration, as shown in fig. 7, 704 indicates a first scanning period, 701 is a scanning period of the first scanning period, a duration corresponding to the scanning period is a scanning duration, 702 is an interval period of the first scanning period, a duration corresponding to the interval period is an interval duration, and 703 is a scanning period of the second scanning period. In the scanning time period, the display device can be in a scanning state, and the connection signal sent by the Bluetooth device is scanned; during the interval period, the display device may be in a silent state, i.e., cease scanning for connection signals transmitted by the bluetooth device.

In this embodiment of the present application, the display device may preset three connection modes, where the scanning durations and interval durations of the three connection modes are different, and as shown in fig. 8, 9 and 10, for example, fig. 8 is a schematic diagram of a scanning period of the first connection mode, where the scanning duration of the first connection mode may be 40 milliseconds, and the interval duration may be 10 seconds; FIG. 9 is a schematic diagram of a scan cycle of a second connection mode, which may have a scan duration of 80 milliseconds and an interval duration of 3 seconds; fig. 10 is a schematic diagram of a scanning cycle of the third connection mode, where the scanning duration of the third connection mode may be 100 ms and the interval duration may be 1 second.
