Anyone please give me some advice .
I attached an ICOMSAT GSM Module to my arduino.
Basically i just started with the demo inside the arduino IDE
So the SendSMS demo worked well, but the TestGPRS one? Not working
I have plugged 4.5v power supply to the arduino and of course the packet data was working good as i have tested it on my phone.
And til now it keeps giving an error , as you can see in these attachments
So help me to solve this error please?
Thank you very much
