Hello,

I have some problems with my GPRS module. The first problem I can't solve is the power problem.
I have a 12v 2A adapter and the arduino module is connected to my computer by USB. I can send en recieve sms and make calls. No problems. But when I disconnect my USB and to module works stand alone only one power (12v 2a). It seems it works, but it doesn't send SMS or anaything. I changed the power jumper in the shield? But it doenst' work. Can anyone help me out.

The second problem is: How can I respons data in arduini. For example. I use the command "AT", and the respons in the hyperterminal will say OK. But can I read this reponse in Arduino. For example: if (response ="OK") ......... else ........

Thanks for helping me out

Wouter

For example: if (response ="OK")

"strcmp (response, "OK") == 0"

Can't help with the power problem without some specs and a schematic.
