AT instruction set: Users can communicate with the Bluetooth chip through the serial port. The serial port uses Tx, Rx two signal lines, and the baud rate is supported. Hold 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200. The default baud rate of the serial port is 115200bps. Instruction set details: (Note: You must enter and enter the line when you send the AT command. The AT command can only take effect when the module is not connected. Once the blue is enabled. When the tooth module is connected to the device, the Bluetooth module enters the data transparent transmission mode).
