Mega2560 + Seeedstudio GPRS Sim900

Hey everyone.

My GPRS shield is running (Serial communication).
SMS/Phone is allready working. But I’m not able to connect to the internet.

Httpaction response with 601 - Network problem.
ciicr response: PDP deact.
at+cgreg=? -> 0,1,2

The Networksettings are:
APN: A1.net
Uname: ppp@A1plus.at
PW: ppp

Does anybody know, how to activate my network connect?

Thx in advanced!

Hello,

I’m using Mega2560 R3 and Seeedstudio GPRS SIM900 V1.2, but I don’t how can I do the communication with arduino. I tried to use the code from wiki, but nothing happen at serial monitor from arduino. I used the library from code.google.com/p/gsm-shield-ard … loads/list (BETA_GSM_GPRS_GPS_IDE100_v302.zip) and the communication wasn’t ok, the serial monitor print:

GSM Shield testing.
DB:NO RESP
DB:NO RESP
DB:NO RESP
ERROR: SIM900 doesn’t answer. Check power and serial pins in GSM.cpp

status=IDLE

I need make jumpers? Modif the code and the pins?

Help me, please!
