Wiring the Bluetooth HC06 / 4 Channel Relay Switching with Android

Another guide how to wire the HCo6 and 4 Channel Relay for switching, The HC06 modules uses BlueCore is a single chip radio and baseband IC for Bluetooth 2.4GHz system including enhance data rates (EDR) to 3Mbps. for more details please refer the the CSRBC417 Datasheet.

The BC417143B interfaces to 8Mbit of external flash memory. When used with the CSR Bluetooth software stack, it provides a fully compliant Bluetooth system to version 2.0 of the specification for data and voice communication.

The chip BlueCore has been designed to reduce the number of external components required. The device incorporates auto-calibration and built in self-test BIST routine to simplify the development. All hardware and device firmware is fully complaints with the Bluetooth version 2.0 plus EDR specification.

Configuration and customization settings using AT Command please refer to this link.

  1. if your using MCU without serial communication it will not work.
  2. if your wiring to a different Digital Pins will not also work.
  try to change the char data start from 1 to 8
  if (data == ‘1’){digitalWrite(R1, HIGH)}
  if (data == ‘2’){digitalWrite(R2, HIGH)}
  and so on…..

    I’m following your steps one by one. I’m using my smart phone for programming arduino nano. But i mistakenly press reset button.
    Is this code case sensitive??
    Can i reprogramme my mcu?

Is this code and MCU case sensitive??
I’m using HC06 bluetooth module for serial communication.
Can i reset my MCU and reprogram again?

Pressing the reset button is not related to the code. reset button is just to reset the micro-controller return the setup & loop state, the same like your going 2 remove the power and put-it back. yes you can reprogram your MCU using bootloader see this link. > https://www.arduino.cc/en/Hacking/Bootloader
