Error creating trace with modem 1.3.6 firmware

[hubert_11]

Hi!

I just succesfully flashed my modem firmware to version 1.3.6 using the nrf programmer and a segger external programmer.
I can still connect over the serial monitor just fine, and all seems to work. But I can't start a trace anymore using the cellular monitor.

I'm using an M1 MacBook, running Sonoma 14.5. 

Whenever I try to start a trace, I end up with this error:

Error when creating trace: unable to locate db directory plugin path: /Users/huub/.nrfconnect-apps/node_modules/pc-nrfconnect-cellularmonitor/node_modules/@nordicsemiconductor/nrf-monitor-lib-js/Release/darwin-arm64/nrfml-insight-source.nrfml

The file does exist on my computer, at that path. I also tried reinstalling the cellular monitor within the nrf connect for desktop app, this did not make a difference.
I then deleted the whole nrf connect app, and reinstalled it, but I still get the same error.

Lastly, I tried to downgrade to a previous version of the cellular monitor, but those previous versions only opened to show a blank screen.

Any tips on how to solve this issue?

Hi, 

Could you try to reinstall the nRF Connect app?

Hi,

What exactly do you mean with reinstalling? 

On mac you don't really install apps like you do on windows. I did remove the nRF connect app and redownloaded it "installed" it again. But that did not make a difference.

Hi, 

Which application are you using? Do you enable CONFIG_NRF_MODEM_LIB_TRACE and CONFIG_AT_HOST_LIBRARY=y as in this course? 

Please also make sure to use the latest version of the cellular monitor (v2.4.0) and nRF Connect for Desktop v5.0.0.

I'm using the asset tracker application on the thingy 91, version 2.6.1.
I do indeed have those configs enabled.

But it seems like the modem update is somehow (indirectly) the cause of this error since I could connect just fine to the thingy trace before updating the modem.

What version of nRF connect for desktop are you using?

Do you download the Apple silicon version of the nRF connect for desktop?

I just started the app again and got the notification that 5.0.1 is now available. And that update seems to have solved it.

I appreciate your help. Everything seems good now!

Happy to hear that.
