Topic: Reset Pin Move to different pin? (Read 2292 times) previous topic - next topic

I need to use pin 7 for another function, but the GSM shield uses this pin for Modem Reset. I notice that there is a solder bridge so that I can disconnect the reset function from pin 7. What will be the effect on the GSM card if I do this?

Could I change the library to use a different pin and solder a different pin to the modem side of the solder bridge?

Any help would be appreciated.......

Yes, you absolutely can.

Reset pin can be redefined in file GSM3ShieldV1DirectModemProvider.cpp. You'll find a line like this:

#define __RESETPIN__ 7

Change for the pin you prefer (avoid pins 2 and 3) and of course put in place a connection. If it runs OK, please let us know the one you have used, so we can tell other people.
