Does someone has experience with SDR analyzing a nRF9160

Sometimes is interesting to see more details of each layer.

I remembered some times ago, that SoftwareDefinedRadio (SDR) comes with a lot of possibilities at a very low price (15-30 Euro).

Therefore I did a short research about “SDR + NB-IoT” and found:

SRSRAN - NB-IoT

Does someone has experience with that?

This is cool and never heard of it. Interesting to see if anyone else in the community has any experience.

Edit: I know that you can get a modem trace but it’s proprietary and requires someone at Nordic to decode. This is definitely a cheaper alternative compared to a protocol analyzer.

For me the Nordic modem trace is great, but sure, only for the nRF9169. You get a lot of information and you can see the IP messages.
The idea with SDR is more to see, if on the radio level the things are as expected. (OK, that requires to first have some experience with working/good radio traces to see then the difference to wrong ones.)
