Communication Interface for Module and MCU

• Asynchronous Serial Communication
  BLE module communicates with MCU by serial port (UART). Default port parameter: baud rate 9600, 8 data, 1 stop, no parity.

• Packet Format
  Transparent transmission mode: BLE module forwards the data from MCU to APP without change. And the same as data from APP to MCU. Instruction mode: Module can be configured by AT command by either APP or PC UART.

• Operation Mode Setting
  Switching between AT command mode and transparent transmission mode: Power on default transparent transmission mode. Send“+++” then return“AT+ok Mode=AT Mode\r\n”, the module turns into AT command mode and AT command are available for setting and reading. Send“AT+exit\r\n” then return“AT+ok Mode=Normal\r\n”, the module turns back to transparent transmission mode and data will be transparently transmitted directly.

AT Command

Notice: Power on default transparent transmission mode, and send“+++” into command mode. AT command finishes with “\r\n” in command mode. Tick ”send new line” in serial port assistant.

AT Command List

“+++”swichs to command mode to transparent

transmission mode.
