Thanks for that Kurt! I'll try it out, well I've already gotten the current setup to work with another library so I don't think there are any problems with the physical hardware connections.
@mjs513, here's the link...
Thanks for the advice, Paul and Kurt! So I tried Paul's code with SoftwareSerial and Kurt's code without SoftwareSerial, but the error still persists
These were the only pins I could use for the MODE and AUX - M0:...
Follow-up - Since the example sketches use the SoftwareSerial library, could that potentially be causing any issues? Could it also be replaced with something else?
