Hi Sodaq Support Team,
I have a NB-IoT Shield Deluxe for Arduino SARA N211 with a Leonard Arduino.
I have uploaded the passthrough code to my arduino board without the shield connected and it looks that is working.
I have done some AT comands throught the Serial Monitor and for some reason, some are working some are not working.
