I use HC-06 bluetooth module on arduino uno and the data which transfers the bluetooth module is the same as the text written on arduino serial monitor, so the problem is I can’t receive data on android using unity3d , i’d be greatful if anybody can post how i can do this.
Check this out, I just found it myself, it could be useful for you 
Seems to be for the kind of Bluetooth module that you are using. I’m trying to find a plguin that will work with something called an RFduino, I’m hoping that this plugin will do the trick!
