Hi, I've assembled a data logging unit with an RTC module, LCD (i2c) display, SD memory card shield and Arduino GSM/GPRS shield on Arduino Uno R3.
Since the sketch was too big for Arduino, I removed some of not used GSM library (Mockup, SMS, Voice, ModemVerification,MultiClientProvider, MultiServerProvider, ScanNetwork) moving all related files in a new folder. I checked on a separate sketch that having removed those files did no affect the GPRS connection and data transfer with GET method works perfectly.
The sketch compiles well, but goes out of memory and it doesn't run.
Is there a way to avoid using GSM library? reducing so far memory usage to what I actually need? maybe with AT commands (I don't know much how they work).
Thanks for any help.
