To implement the RFCOMM protocol I used a bluetooth sniffing tool called PacketLogger developed by Apple.
It enables me to see the bluetooth communication between my Mac and any device.
All the information about the Wii controller is from this site: http://wiibrew.org/wiki/Wiimote
And the old Wii library created by Moyuchin: https://github.com/moyuchin/WiiRemote_on_Arduino
And at last I would like to thank Oleg from http://www.circuitsathome.com/ for making such an awesome shield!
