Therefore, a full-function scheme can be completed by one SoC single chip, the I/O resources are rich, the size space required by design is small, and the hardware cost is low.

The working principle of the wireless Bluetooth handle control circuit is as follows:

when the control circuit works in a Bluetooth broadcast mode, the Bluetooth main control module 4 pulls high and low from the B _ LED control port to control the lamp DL1 to flash quickly, and when the control circuit works in a Bluetooth connection state, the Bluetooth main control module 4 pulls low the B _ LED to enable the lamp DL1 to be normally on (in the two states, the other two control ports, namely the control ports R _ LED and G _ LED, output high level to close the lamp DL 1);

when the user switches the modes, the bluetooth master control module 4 respectively controls the B _ LED (blue), the G _ LED (green), and the G _ LED & R _ LED (green & red are simultaneously on, and finally, yellow is presented) to be always on or to blink (when the modes are switched, three modes are provided, and the indicator lamps respectively use blue, green, and yellow for indication, when the mode is switched to the yellow for indication, the G _ LED (green) and the R _ LED (red) need to be controlled to be simultaneously on, that is, the color finally seen by people is yellow).

When the Bluetooth is in the low power mode, the system can be operated at full speed by waking up by pressing any one of the keys J3-J9, J68 and J69. When the key is pressed down, the high level of the diode of the corresponding key in the diodes D1-D9 is conducted, so that the high level is converted from the low level to the high level and is sent to the awakening pin EXT _ INT, and the Bluetooth main control module 4 awakens the hardware part after detecting the awakening pulse.
