Still only xxx showing bottom left
Are you referring to the joystick position field at bottom left of android device screen ?? :astonished:
This should indicate joystick position at App start up, even before any connection
It should read (-100,-100) for South West position and (100,100) for North East position
Interesting point is that button B5 stays locked the same as other buttons until pressed again to release. (I did notice at one time it did act like a push button – maybe that was when data got fed back).
This is normal behavior when not connected
My only problem now (apart from error in BT board configurator mentioned above) is the failure to get a signal from Arduino to Android.
- You can follow joystick position and buttons state on you Serial Monitor
- Datafields don't update, B5 is not in "push" mode

I was talking about App version, should be V4.0 OK ??
the AT command AT+UART? returned: 57600,0,0 Is that OK?
According to documentation
Param2 = stop bit: 0->1 bit 1->2 bits
Param3 = parity bit: 0->None 1->Odd parity 2->Even parity
Arduino serial is 8N1 (1 stop bit, no parity)
UNO TX LED flashes about every 2 seconds and whenever a button is pressed. When the joystick is moved it constantly flickers,
This reflects the data flowing from Arduino to Serial Monitor
then after about 10 seconds of continuous joystick movement the TX LED locks on. Opening the serial monitor window seems to return it back to normal.
Strange :relaxed: :relaxed:
Did you change any setting in Advanced options ??
Try "reset Option" to restore initial parameters
EDIT: also set Refresh interval @100ms, Timeout count @every 10 intervals
Finally let me have a link to your specific BT board
