I beleave you are facing two non related problems
- Communication with your BT card (your task)
check pairing, Baud rate, connection to Arduino (Menu/Connect)
I use a JY-MCU rev1.05 board
Onboard LED should be flashing when powered and gets solid red when connected
Connect TX board to RX (D0) Arduino
Above Arduino sketch has been updated to V5 (removed SoftwareSerial)
For sketch upload, don't forget to disconnect board TX from Arduino D0
- UI display on tablets (my task)
I will publish today on Google Play a new version insuring compatibility with tablets
Edit: Joystick Bluetooth Commander V2.2 is now available
Please make sure that application is configured as follow:
- Data Range -50 to +50
- Data display Joystick position
- Data format STX and ETX
- Refresh interval 100ms
- Button1 data to send '1'
- Button2 data to send '2'
