Example for N2X library

Hello community,

I am currently working on a school project with a SODAQ SARA AFF N211 and apparently I have to use the N2X library to communicate with the NB-IoT module while running my Arduino Sketch. The problem is, that the library isn’t that well documented and I wasn’t able to find any examples on the internet.
Could anyone please provide me with some examples how I can send and receive commands.

Thank you in advance
