When powering on the GPRS shiled what do the lights mean? Is there a document for this? Right now, my LD1 light is blinking green at approx 2 blinks a second, the PWR light is green, and the status light is Red.
I have a GPRS Shield, Arduino Uno, and a SIM Card, but I cannot send an SMS or get a response from the GPRS Shiled, and I think the lights are trying to tell me why, but I don’t know. Thanks.
