nRF9160 DK Asset Tracker not reliably finding network

ERIK

I am having trouble getting the nRF9160 DK to find a network running the Asset Tracker than came in the device.  It appears to reset after 15 seconds of LED 3 blinking.  I can connect the LTE Link Monitor and watch it do that.  Secure Boot boots to Zephyr and then about 15 seconds approx later it says it failed (nrf_cloud_connect failed: 60) and starts all over again.  Really difficult and unreliable to get to the state of LED 3 and LED 4 both blinking.  Sometimes just stops with LED 3 lit solid.

I have had it connected a number of times, but not reliably. The SIM is registered.  This is making it difficult to get the things linked to my nRF Cloud account when I am having trouble even getting to the pattern entry portion of setting this up.

Is there an issue with the asset tracker that came in the device such that it won't connect?  Something else I might have going on?  I have not loaded anything different into the DK than what it came with.

Thanks,

Erik

    I'm sorry, but this is still the output of the asset_tracker example code. I need the output of the AT_Client example code, which gives more information about the board. Please program using this file: at_client.hex

    Sorry, misread your request.

    Here is with AT client.

    Note that below the AT client first seemed to stop responding with the LTE indicator on LTE monitor flashing.  But I reset the DK board and then it worked.  You can see where that happened in the log below where it shows AT+CFUN? sent multiple times in a row right before booting Zephyr.

    Thank you, Erik! This is exactly what I needed. I will have a look at the output with a colleague. 

    Can you please try the solution given by Bjorn in the related support task: https://devzone.nordicsemi.com/support-private/support/222766
    Let me know if that helped with anything, if not we will continue with at_client output.

    Thanks!

    Tried Bjorn's suggestion, using the .hex files he attached.  Same results.  I posted the LTE Link Monitor terminal text in that thread.

    Could there be some HW quirk with this nRF9160 DK board or with the SIM card, where I'd be better off trying another dev kit instead of continuing with this back and forth?  Maybe you could work with a vendor like DigiKey and have them ship another to me?

    Thanks,

    Erik

     The output tells us that the modem is working as it should, as the board is receiving an IP address. I presume this was before Bjorn's suggestion. We need to figure out one last thing before shipping a new board, please see my answer in case #222768. There might be a problem with the board's certificates.
