I am using GPRS shield v1.0 and I see now in the wiki a solution for sotfware power up (http://www.seeedstudio.com/wiki/GPRS_Shield_V1.0#Power_up_and_power_down).
I have tried the code proposed in the previous link but it does not work.
pinMode(9, OUTPUT); digitalWrite(9,LOW); delay(1000); digitalWrite(9,HIGH); delay(2000); digitalWrite(9,LOW); delay(3000);
Do you know if my shield version supports SW power up? If yes, any suggestion of what I may be doing wrong?
Thanks for your support!
