I was thinking since there's no Bluetooth keyboard support in MicroPython for the #RaspberryPiPic but there is a C bluetooth keyboard demo I'd hack the demo and turn it into an mpy module. However the mpy linker can't seem to figure out that the bluetooth stuff is built into micropython:

LinkError: build/keybt.o: undefined symbol: hid_device_request_can_send_now_event
