Arduino BT and WT11

Hello,

the Arduino BT does some "hidden" communication with the WT11 BT module? Or just sends and receives data from the serial? In other words, if I erase the atmega chip and program it with my own code (plain avr gcc, no arduino extensions) will I still communicate via BT with virtual COM?

No answer because I either posted in wrong section or it's a FAQ question? :relaxed:
