Key Notification

Enabling key notifications enables key press notification to the app.
UUID: 0x2902
Handle: 0x0037
Write 0x0001 to enable key notifications
With key notifications enabled, the application will be notified of key presses via a single byte as

follows

0x01 – SW2
0x02 – Joystick ‘B’
0x04 – Joystick ‘PB’ (push button)
0x08 – Joystick ‘A’
0x10 – Joystick ‘D’
0x20 – Joystick ‘C’
Any simultaneous button press will yield a byte that combines the individual bits corresponding to

the buttons pressed. Thus “SW2” pressed with ‘A’ will give 0x09; ‘PB’ with ‘D’ will give 0x14.
