Great job KAS , i test again and you was right,your app works great with Android 2.3.5,and the HC-06 also compatible (bad thing is i don't recive any data,i can only send) :D:D so...
Based on your replay at post #146 i am trying to modify the arduino code with your permision,so that on vertical move a DC Motor, and the orizontal a Servo (for steering)...
the joyY control Vertical joystick movement ,and "joyX" the horizontal right ?
I will post the code as soon i will get it work ... Thank you ,Congratulations again for the app,Karma up
