Does it make any difference if you do

mySerial.print(RFID_READ, BYTE);

instead of

mySerial.print(RFID_READ, HEX);

I know the datasheet specifies that the RFID Read command be sent in hex and I'm no expert with the arduino or reader so I may just be talking out of my butt here  :smiley

If you've made any progress would you mind sharing?
