[0027] Step S11, receiving the status display instruction sent by the control terminal;

[0028] The Bluetooth device in the embodiment of the application receives the status display instruction sent by the control terminal; wherein, the control terminal includes a terminal device with Bluetooth function such as a smart phone, a tablet computer, and a smart wearable device. The status display instruction is used to instruct the Bluetooth device to display the current status in the process of connecting with the control terminal or after successful connection.

[0029] Further, when the control terminal sends the status display instruction to the Bluetooth device, it uses the Bluetooth serial port protocol (Serial Port Protocol, SPP) or the Bluetooth low energy protocol (Bluetooth Low Energy, BLE) to display the current status of the Bluetooth device. The status is included in the status display instruction and sent to the Bluetooth device. The status display instruction includes ID information of the Bluetooth device, data packet length, command ID, and cyclic redundancy check code. The command ID corresponds to the display state of the Bluetooth device. The status display instruction is sent to the Bluetooth device in the form of a data packet.

[0032] Optionally, in another embodiment provided in this application, the parsing the status to be displayed by the Bluetooth device specified by the control terminal in the status display instruction includes:

[0033] Read the ID information of the Bluetooth device included in the status display instruction;

[0034] Determine whether the read ID information of the Bluetooth device is consistent with its own ID information;

[0035] If they are consistent, acquire the command ID contained in the status display command;

[0036] The status to be displayed by the Bluetooth device is determined according to the command ID.

[0037] In this step, after the main chip of the Bluetooth device receives the data packet of the status display instruction sent by the control terminal, it parses the data packet to obtain the ID information of the Bluetooth device contained in the data packet, and compares its own ID information with The ID information parsed from the data packet is matched to determine whether the two are consistent. If they are consistent, it means that the Bluetooth device to be controlled by the control terminal is the Bluetooth device that received the data packet; and then further from the state The command ID is parsed from the data packet of the display command; the command ID is a code, and each different ID code corresponds to the display state of a different Bluetooth device. Therefore, the command ID can be determined after the command ID is parsed The control terminal wants the Bluetooth device to display in what state.

[0047] Instruct the display control chip to call the flashing mode corresponding to the command ID, so that the display control chip controls the LED light strip to display the status of the Bluetooth device in the corresponding flashing mode.

[0048] In this step, if the display module is set to display the status of the Bluetooth device by the LED light strip, the flashing mode corresponding to the command ID is called. Then instruct the display control chip to control the LED light strip to display the corresponding flashing pattern to characterize the display status of the Bluetooth device. Among them, the LED light strip is composed of several LED RGB (Red, Green, Blue) three-color lights. The control chip of the light strip can set the color and blinking timing of each RGB light to realize different display modes. For example, the light strips breathe, race, flash, etc. under different colors, and each command ID corresponds to a flashing mode. For example, command ID = 01 corresponds to LED light with green marquee flashing; command ID = 02 corresponds to LED light with green light breathing .
