Arduino Bluetooth Controller

Hey Guys,

I have an Android app named “Arduino BT Joystick”. I wanted to know what output is given via Bluetooth from that app.

So, I wrote a code for my Arduino Mega ADK connected to an HC-06 Module[It is properly connected].

char incomingChar = 0;

void setup() 

void loop() 
    incomingChar =;


I paired the HC-06 with the app and started the Serial Monitor, but I get a blank screen even on pressing buttons on the app.

Is my code correct to do the task?

there's a sketch for method 3 you will want to look at

Have you checked the Android Bluetooth Joystick thread? It is probably the biggest thread on the entire Arduino Forum, and must surely have what you want to know by now. I don't think you need to do anything about bluetooth AT mode, least of all, HC-05 AT mode.


Can you please post the link of that thread here..????

You see,

I don't have a HC-05. I have only a HC-06
