LTE Link Monitor and Trace collector not possible with nRF9160 dev-kit - using Apple Macbook Pro - serial port issue

Oliver Wierichs

Hi,

I am using an nRF9160 dev-kit and I am debigging some connectivity issues.

Unfortunately there is some random bahaviour on the Serial Interfaces, which are exposed to my Macbook.

Sometimes it is not possible to use the Trace Collector, sometimes it is working.

Port #2 is not selectable (it is the USB interface with 2 ports).

I have the impression it depends on the way, the USB ports are enumerated. I.e. sometimes it is working.

On Windows and Linux, I do not have the same problem. 

But on Mac the "Auto Device/Port Filter" is not supported, I get individual ports.

I am attaching a few screenshots, which hopefully expain my problem.

And here are also some logfiles.

    Hi Martin,

    I know, that the Auto device/port filter is not supported on Mac and I need to selact manually.

    But my problem is, that not all ports are coming up properly.

    I usually can connect only to 2 ports out of the 3, which I should get:

    1) the nRF9160 AT command interface

    2) the nRF52840 showing this message: NRF52840 board control statically configured. DK Uptime is 3080 seconds

    3) Trace Collector coming up randomly, but quite often not.

    regards,

    Oliver

    Hi Oliver,

    Correct,

    #1 there are is one port from the console of the nrf9160 (at_client in your case),
    #2 one port for the nrf52 (just running the boardcontroller app) and
    #3 last port is used for modem tracing when thats enabled(CONFIG_BSD_LIBRARY_TRAACING=y)

    The last port should only be used with the Trace Collector app. (opening that port in LTE Link Monitor would not work properly).

    Do you have issues using the Console port from nRF9160 with LTE link monitor and the modem trace port connected to Trace Collector?

    Could you give more details if that is the issue? (5/6 screenshots are corrupted)


    Best regards,
    Martin L.

    Hi Martin,

    the Console port of the nRF9160 is usually working fine.

    My problem is the 3rd port, which is numbered as port #2, i.e. the port for the Trace Collector App.

    When I try to open it, I get an error "Couldn't identify serial port"

    I have added another logfile and screenshot.

    Hopefully the PDF works.

    Regards,

    Oliver

    Hi Oliver,
    Are you able to test the card on another platform to rule out any issues with the kit?

    It is very strange that it select "Could not fetch serial number for serial port at /dev/tty.Bluetooth-Incoming-Port"

    That is not a Jlink Serial port.

    I have tested this on Mac, Windows and Linux.

    Only on the Macbook I have a problem.

    A colleague managed to replicate the issue on a MAC.

    When he opened the LTE Link monitor #0 was the nRF52, #1 was the modemtrace and #2 was the console logging. 
    Similarly in the Trace collector: #0 yields almost no data, #1 yields reasonable sized data (for a modem trace), #2 is not connectable
    We also verified that the modem trace taken on port #1 was valid.
    Note: when he tested a bit later the port had changed, so there seem to be some irregularities on MAC. (I will make sure to report this internally)
    Could you try another serial port in the trace collector app?
