Usage of Cellular Monitor with non Zephyr OS

[lobaro-theo]

Hi,

I'm using the "Cellular Monitor v1.0.2" to collect modem traces from a custom board on a non Zephyr based eco system for the nRF9160 - we use FreeRTOS. As a consequence our normal uart text log output does not follow any convention Zephyr did introduce, e.g. AT command responses etc.

Question 1:

Are the displayed information field "LTE Network", "Device", "SIM" etc. sourced from the actual modem trace? Or are these information displays sourced from parsing the "normal" non trace log of the device in question? I'm asking since these fields are not populated in my tests but a modem trace is written. 

Question 2:

I also attached the modem trace to let someone at Nordic check if this is a valid modem trace. Is this modem trace a valid trace file? After this I will create a new topic with the actual modem related problem to be solved hopefully.

Thank you.

I believe it is taken from the trace, but I need to double check this with the developers.

I was not able to decode this trace. There is some information in there (as in, the file is not empty or full of zeros), but it doesn't really look like a modem trace.

Are you sure it is from the right UART, or that there is nothing else in your application that uses UART1?

Best regards,

Didrik

The developers confirm that the information is taken from the modem trace.
