Hi All Gurus,
I need help in GSM 800l module. I purchased this unlocked module, initially it was giving CME Error 10, after i pulled out the SIM card and reinserted it couple of times, now my module is giving CME Error 100.
Need help in resolution of this issue. Internal Module LED is blinking very fast, once per second.
I am using UNO, with only one module that is GSM 800l, no shields direct the module, pin details are as under;
I have nothing else on this UNO.
Help would be appreciated on this issue please.
