I amI have a very strange issue. My sketch works great, but it is not working after i disconnect/connect the power supply (external 12V, 3.5A)
Sketch works if i press manually the RESET button of the Arduino uno or that in GSM Shield.
I am not a specialist but it seemd to me like a booting problem or something? Is this right? How can i make it reset every time the power is reconected? Is there such thing?
Thanks in advance, i hope to solve this problem ASAP.
It sounds to me like there is something to do with gsmbegin(pin,restart) because when i set it to
if(gsmAccess.begin(PINNUMBER,false)==GSM_READY)
instead of
if(gsmAccess.begin(PINNUMBER)==GSM_READY)
added , false parameter everything vorks fine....i am not sure why it works better with the false parameter....
