Hi all,

The SparkFun LTE CAT M1/NB-IoT Shield - SARA-R4 run well with an Arduino uno but when I replace the arduino UNO by an Arduino MEGA using the “Sparkfun_LTE_Shield_Arduino_Library.h”, none given exemple works well. Do you know where is the issue ? Is This library compatible with an Arduino Mega ?

Thank you.

The library uses software serial and the pins the shield uses for serial are not software serial compatible on the mega. It might be possible for you to modify the library and shield to use compatible pins.
