Unique ID of board

SARA AFF
1

Hi!

I am using multiple Sara R410M boards which will be roaming and sending data through NB-IoT. For this I would like to uniquely identify each board sending a message so that I know who sends what. Is there any way this could be done in code without having to manually configure something?

The IMEI is guaranteed to be unique.There should be a function in the library for reading the IMEI, so you could then include that in your payload.

Thank you, that is exactly what I was looking for.
