I am trying to use the seeedstudio GPRS 1.4 with a Mega R3.
I am using the demo sketch in the wiki. The board turns on ok and the red and green LEDs light and blink as they should. I have the jumpers set for software communication. I set the terminal for 19,200 8 N 1. I did set it to add CR. I can not get the terminal to take the AT commands. I am plugging the shield into the Mega. Is there some issue of the Mega vs UNO? Do you have some instructions or sample code to make it work? Thanks.
