Control Commands

  • Pin Definition
  • All pins connect to ground pin of LED
  • All commands should be end up with \r\n
Pin MCU PIN v1.1 Command v1.0 Command Note

  1. When Bluetooth made connection, BT status LED will keep constant high, you can not write it low, notice. But you can read the BT status via this pin.

Serial Debugging

Bluetooth UART connect to serial UART debugger

  • board TX to cable RX, board RX to cable TX:
Receive Action Send from example
Serial monitor only response < Phone CMD "N1"
Serial monitor NOT response < Serial monitor CMD "N1"
Phone get < MCU feedback "mssage is ..."
Serial monitor NOT get < MCU feedback "message is ..."

MCU UART connect to serial UART debugger

  • vice verse connection
Receive Action Send from example
Serial monitor response < Serial monitor CMD "N1"
Serial monitor NOT response < Phone CMD "N1"
Phone get < MCU feedback "message is ..."
Serial monitor get < MCU feedback "message is ..."
