Hello
iam using itead sim908 Gsm/Gps/Gprs Module with Arduino Uno, iam trying to send Gps coordinates by Sms message and by gprs to internet server, but cant run it both same time, Although it's work separately.
when i try to send GPS coordinates via SMS message and send data via gprs to server same time i have this error :
ERROR: SIM900 doesn't answer. Check power and serial pins in GSM.cpp
this is my code, any one have a solution ?
