Hi kas, here's an update - everything works A-Ok. Very cool.
I am running the Arduino sketch shown in your original post, except that I am using an ATmega1284P with 2 UARTs, so the BT data comes in on Serial1 and goes out Serial to the terminal emulator. Joystick, haptic, and button on/off all work good. The control menu on my tablet is as shown in reply #9.
The only question I have is that, when the joystick is at rest position shown as (0,0) on my tablet, the data received at the Arduino end = 60,60, and then it goes from 10...110 as I move the joystick. Obviously, the data range is set to -50,+50. So, what's the 60,60 business, I didn't see it mentioned anywheres?
Here is my system:
- ATmega1284P board.
- BT module = generic clone:

Robot or human?
