Hey guys.

I try to connect Elecfreaks Bluetooth Shield v1.2 to Arduino Mega 2560.
It working in AT mode, i can send AT commands, but i cant do main command AT+LINK=



In port monitor it look:
------->  AT+LINK=8400,D2,35170C
FAIL
+INQ:8400:D2:35170C,58020C,FFCE

+INQ:8400:D2:35170C,58020C,FFCE
+INQ:8400:D2:35170C,58020C,FFCE
