  RN42 HID raw report format:
  |start(1 byte)|length(1 byte)|descriptor(1 byte)|data(length - 1 [for the descriptor])
  Keyboard:
  |0xFD|9|1|modifier|0x00|code 1|code 2|code 3|code 4|code 5|code 6
  Keyboard modifier bits (sent as one byte)
  bit 7     |bit 6      |bit 5      |bit 4  |bit 3  |bit 2  |bit 1      |bit 0
  rt GUI    |rt alt     |rt shift   |rt ctrl|lt GUI |lt alt |lt shift   |lt ctrl
  
  You must initialize the Serial library in your code before you call any of these functions.
  The default speed for the RN42 is 115200 - add this in the setup function Serial.begin(115200);
