GPRS Shield

The shield don't find the network, and i don't know why . I fed with 4.5 and 6 and 9 and 12V because I read that there were problems with the power shield but to no avail. The LED still flashes every 8ms. HELP

Hi, I want to know if i can receive massage with this GSM shield or not, which command do i need to use if i want to receive a msg or voice call?

i had about the GPRS firmware update (1137B03SIM900M64_ST_MMS),have added the tutorial on your wiki page? if not i would want you to add it so that, i can update my GPRS v1.4 to send MMS messages

Hi.That's great! Did you have made a tutorial for that?If so,you can write a blog and show us the link, or post it on our forum , or maybe send it for us.Could you?

I use GPRS shield v1 with my arduino mega 2560 board. When i send At commands i don't see any result in SSCOM serial monitor.I try to send AT+IPR=19200 command and i still don't see any thing in the serial monitor

If you want to use GPRS shield with Mega,you need to modify your program and schematic. 1)Program:SoftwareSerial GPRS(7,8)----SoftwareSerial GPRS(10,11); 2)You need connect pin-7 to pin-10(pin-8 to pin-11) by jumper wire.Because of not all pins on the Mega and Mega 2560 support change interrupts.
