This command will enable GATT over HID (GoH) support, which allows you to emulate a

HID key code values don't correspond to ASCII key codes! For example, 'a' has an

HID keycode value of '04', and there is no keycode for an upper case 'A' since you

# send 'abc' with shift key --> 'ABC'

AT+BLEKEYBOARDCODE=02-00-04-05-06-00-00
