Adjusting the RWDemo profile to use the hardware trigger for reading RFID tags does nothing to initiate the actual change over to the hardware trigger usage. Playing with the different available settings in what the hardware key can be inside of the additional RFID settings also doesn't do anything. I am able to confirm that the UI button in the RWDemo app does in fact work and read RFID tags, so it doesn't seem to be an issue with the actual RFID reader inside of the device.
