[SOLVED] send string to atmega32 through bluetooth hc-05 module


This Content is from Stack Overflow. Question asked by Mihiranga Silva

If I want to send a string like ” Hello World” from a mobile phone to a Bluetooth HC-05 module, then how to handle this string and make my logic accordingly …? Is there any function to convert string to char? I am using an ATmega32 microcontroller to control HC-05.


I think you can create an array to receive the command in the function of microcontroller side. By the way, which app are you using for testing your Bluetooth module? I recommend you use this one: https://play.google.com/store/apps/details?id=com.clarence.bluetoothserial, with which you can customize your frequently used commands as buttons. It’s very convenient.
