Unity-Arduino Bluetooth connection

Hi everyone!
I hope this is the right section for this thread.

I have an Arduino board, connected to a HC-06 Bluetooth module: right now I'm controlling it thanks to BlueSerial Beta app from a tablet. I can send four different letters (a,b,c,d) through the app and each letter will activate a different device connected to Arduino.

I would like to send the same letters but not manually: instead, I would like to send them from Unity, using my PC'S Bluetooth. I'm afraid I can't upload any script example, since I really don't know where to start: I just want that, if I give a certain input in the Unity scene, the letter "a" must be sent to the Arduino board.

I hope my request is clear, thanks to all who may help!

 

Use this API to establish the communication between your PC and the Bluetooth Device and then send the object data over the air.
