I have been looking for a asynchronous library for my GSM module for a long time and the best I could find so far is the library developed by Seeed Studio. HERE
My GSM Module HERE
According to the documentation THIS library can be used with AltSoftserial. I am no expert but I assume that the softwareserial call’s inside the library must be changed to Altsoftserial.
I am currently reading an xbee aswell via Hardware serial. How can the library be modified to use hardwareserial instead?
The GSM module will be in production on a Mega. Currently testing on UNO.
