Starting with firmware 6.10, Roving Networks RN41, RN42, RN41XV and RN42XV modules support both SPP and HID in the same module. By default, the bluetooth module powers up in SPP profile mode. It can be switched to HID by issuing S~,6 command in CMD mode or by pulling high GPIO11 (Pin 9 on XV modules) during power up.
