Hello,

I took over this case from my colleague.

You should use probably use NCS 2.6.0 for this course for now.

Also, are you using the Cellular Monitor for reading the traces?

We have a blog post about it as well: Introducing the Cellular Monitor

Could you post screenshots of the resulting traces?

As for the build log, have you tried to add id using the "Insert->Code" button in the bottom menu?

Best regards,

Michal

Hi Abhijith,

I'm doing the exercises on an nRF9160DK.

Building the project from the exercise as-is results in an error from the linker.

I had the relevant part of the build-log here, but somehow the devzone forum kept popping up an error message when i tried to post, "An error occurred. Please try again or contact your administrator.'. Weird. Posting without the build-log text does work, as you can see..

But, as i said, i could work around this by adding the nrf91-modem-trace-uart snippet.

The thing I haven't worked out yet is that the resulting trace only contains LTE RCC DL_DCCH and NAS-EPS protocol lines, while excersise 7.2 shows all sorts of other lines (AT, IP, DTLS, ...).

Hello,

Will you be able to share the error message you are getting while trying the Developer academy exercises? I recommend sharing the entire log, if possible.

Also, are you trying this on our nRF9160DK, or is this a custom board?

Kind Regards,
Abhijith

Hello,

I wanted to inform you that I have been assigned to this case and have started reviewing it. I will need a bit more time to provide a proper response to your query. You can expect a response by tomorrow evening, or at the latest, by Wednesday evening.

Kind regards,
