I can not wake up the communication with my A6 mini gsm/gprs module. Does anybody know how is it working in fact?
5volt, GND, URX and UTX legs ware connected and the SIM card is valid, but only the NULL character was received. On the A6 board the red led is lighting continously and the blue led is blinking during the NULL character sending.
If somebody tried this type of board send me recommendation please.
