- Connect Arduino PIN 10 to TXD of HC-06.
- Connect Arduino PIN 11 to RXD of HC-06.
- Connect GND of HC-06 GND of Arduino.
- Connect VCC of HC-06 to 5V of Arduino.
After this LED on the HC-06 should be blinking.
- In Arduino IDE go to Tools => Serial Monitor.
- Make sure you have selected a baud rate of 9600 (if you are not changed the baud rate of HC-06 before) in your serial monitor. (line termination both \r and \n)
- Now type "AT" in the serial monitor with out " and press enter.
You should see a response "Ok", if not then make sure you have followed the above steps correctly.
