Hi robomike,

I was having the same problem. I was able to get the register sketch to compile and upload to a SAMD board by doing the following:

• Comment out line 34:

//SoftwareSerial lteSerial(8, 9);

• Changes lines 43 and 44 to:

#define SerialMonitor SerialUSB
#define LTEShieldSerial Serial1
