can't get modem trace in cellular monitor for AWS sample code.

Hi,
    

I'm facing connectivity issues with my nRF9160DK board,SDK Version: 2.6.0,Modem Firmware Version: 1.3.6.while trying to connect to AWS IoT using the sample code provided. Despite following the instructions, I couldn't establish network connectivity.

Your team member suggested providing a modem trace file using the cellular monitor to diagnose the issue. However, I encountered an error when trying to enable modem trace functionality by adding CONFIG_NRF_MODEM_LIB_TRACE in the project configuration.

* Terminal will be reused by tasks, press any key to close it.

Without this configuration, trace functionality remains disabled, hindering our efforts to identify the connectivity issue see below screenshot just red mark in trace no further moves.

Could you please guide me on how to successfully enable modem trace functionality or suggest alternative methods to diagnose the network connectivity issue?

I've attached the document provided by your team member for your reference.

Let me know if you need any further information or logs regarding my setup and the encountered error.

Thank you for your assistance.

Hi,

Thank you for providing the output of mentioned AT commands (in your second ticket). We will look into it.

Regarding modem trace, could you verify that 2 config options shown below are added to your project configuration?

CONFIG_NRF_MODEM_LIB_TRACE=y
CONFIG_AT_HOST_LIBRARY=y

You can read through this blog post and check that you have not skipped some steps.

Best regards,
Dejan

Hi,
    
Regarding the modem trace configuration options, I followed the steps outlined in the blog post you provided and ensured that the two config options are added to my project configuration. However, upon flashing the code, I encountered the following error:

07:21:02.703	Error when creating trace: unable to locate db directory plugin path: C:\Users\pmariyappan\.nrfconnect-apps\node_modules\pc-nrfconnect-cellularmonitor\node_modules\@nordicsemiconductor\nrf-monitor-lib-js\Release\win32-x64\nrfml-insight-source.nrfml.

Could you please provide guidance on how to resolve this error and successfully create the modem trace?. Any insights or suggestions you can offer would be greatly appreciated.

Additionally, in second ticket response, you mentioned providing additional input about modem trace with snippets using the west build. I will also give this approach a try concurrently to see if it resolves the issue.

Furthermore, regarding the issue with AWS IoT connectivity, I understand that modem trace may provide valuable insights. Once the modem trace is successfully configured, I would appreciate any guidance or suggestions on why AWS IoT is not connecting.

If there are any alternative or simpler code examples or way available for connecting to AWS IoT, I would find it immensely helpful if you could share them.

Thank you once again for your assistance and support.

Hi,

It could be useful to see which result you get using snippets. Please try to use snippets when building you application with west to check if you get the same result. Are you able to get modem trace this way or still seeing the same error?

Best regards,
