I need help to understand what is happening with the LoRaModem class. In the MKRWAN examples, what do they mean by
"// Uncomment if using the Murata chip as a module
LoRaModem modem(Serial1);"? If I uncomment it, it still works, but I don't know why or where.
I assume it has to do with the SERCOM configuration for the SMD21 controller, but I'm having a lot of trouble understanding which pins are being used in both the standard configuration (LoRaModem modem) and the alternate configuration above.
The library documentation for the MKRWAN1300 is inadequate. I printed out the MKRWAN.h file, but my C++ skills are not that great. I see where the LoRaModem class is instantiated, but not how the port is configured.
