Error when creating trace: unable to locate db directory plugin path

[nobuddy]

Hi Nordic Team,

I'm trying to enable modem tracing on the gnss sample code on my nrf9160dk but have been getting the following error:

Error when creating trace: unable to locate db directory plugin path: C:\Users\x\.nrfconnect-apps\node_modules\pc-nrfconnect-cellularmonitor\node_modules\@nordicsemiconductor\nrf-monitor-lib-js\Release\win32-x64\nrfml-insight-source.nrfml

Per suggestions on similar threads with this issue, I've installed other versions of cellular monitor from version 2.1.0 to 2.4.1 with no success; all produced the same above error.

I also tried uninstalling and reinstalling the nRF Connect for Desktop, no success either.

I confirmed the file path in the error exists, see image below:

My prj.conf has the below code to support modem trace and "nrf91-modem-trace-uart" snippet in the build conf.

CONFIG_NRF_MODEM_LIB_TRACE=y
CONFIG_AT_HOST_LIBRARY=y

I'm using SDK v2.6.2, Toolchain v2.6.2, and mfw_nrf9160_1.3.6.

Please let me know if you could help me resolve this tracing issue.

Hello, 

This is most likely due to the application not printing the modem FW at start or the modem trace starting after it has printed. What happens if you press reset on the DK after starting modem trace?

Another work-around is to choose the modem FW manually in the Cellular Monitor. Did you try this?

Kind regards,
Øyvind

Choosing the modem FW manually solved the error. Thanks again Øyvind!
