I just bought
ADH8066 Evaluation Board and
ADH8066 GSM Module
put them together, connected to the PC, held the ONKEY for 2 seconds, wrote a small sersial port message sending program, but all I see is the TX led going on and off as I perform the command sending.
Nothing else happens. Nor the RX led indicates nor the program catches a responce.
Here is what I do (C#):
SerialPort sp = new SerialPort("COM4", 115200,Parity.None,8,StopBits.One);
Can anybody help me, please?
