Unexpected board reboot during LTE connection on custom boards (nrf9151)

HoovinSchoovin

Hi, 

We are experiencing a weird issue on our custom boards which have a nrf9151 chip

We are using emnify sims and have experienced the following:

  • On some boards, when connecting to specific networks, the device starts up for 10-20 seconds before restarting in a loop indefinitely. This is before network connection is established. 
  • This is only happening on select boards and select networks. ie, we can ban AT&T and force the device to connect to t-mobile which fixes the issue (at least where we are in the short term).
  • The issue seems to affect by location (ie boards work perfectly at the office, but don't out in the field). 
  • If I block the AT&T network, after it has been looping, we often get into the 30min lockout.

I have added three traces below. They are:

  1. Trace1 is AT&T on a board that is not having issues (as far as we are aware). This operates as expected.
  2. Trace2 is same sim on a board which is having issues - it gets in a bad device resetting loop
  3. Trace3 is putting it back into a good board but there is a modem reset loop lockout

I have also added a log of the resetting behaviour with modem logs enabled. 

Any suggestions / advice would be appreciated.

    Hello, 

    The initial issue I see from the application log is that you device is rejected by the network with EMM cause 11, which according to 3GPP TS 24.301 Annex A (Cause related to subscription options) means:

    Cause #11 – PLMN not allowed
    This EMM cause is sent to the UE if it requests service, or if the network initiates a detach request, in a PLMN
    where the UE, by subscription or due to operator determined barring, is not allowed to operate.

    We are using emnify sims

    What networks does these have an agreement with? 

    Will forward the modem traces and have our team analyze. 

    Kind regards,
    Øyvind

    Forgot to ask, but exactly where are you seeing this issue? And where in the logs are the resets?

    Thanks.

    Hi Oyvind, 

    Thanks for getting back to me. 

    Resets occur at "buzzer: Initializing buzzer" in the logs. There are no logs near reset that give any clue as to why it is happening, the last log is event_handler_list_dispatch. 

    I am worried that the PLMN not allowed may be a byproduct of blocking tmobile on the emnify portal to replicate the issue i was experiencing specifically with AT&T. Is this what you may expect if a network was blocked on the network side?

    Emnify sims have been working with AT&T in some cases, which makes me believe that there are agreements in place but your suggestion will prompt me to reach out and confirm with them too. 

    Thanks for sending over the traces.

    Thanks for elaborating.

    I don't think this should give this error, but I will need to discuss internally. 

    Where in the world are  you testing this?

    Thanks Oyvind, 

    That would be handy to know, if there are any suggestions internally please let me know. 

    I am in Boston, USA.

    Upon further analysis, I think i can rule out Emnify as the cause since it also happens on Hologram sims (i assume when it attempts connection o AT&T, but don't know since the trace seems to stop prior to connection). 

    I did a test: hologram sim in the "bad board". When at home, it works as expected. When i walk down a couple streets, it goes into the board reset loop. When i come back, it works. To me that suggests it could be network or tower dependent? 

    We've also identified that the hardware has something to do with it. Ie we have the bad board with another board both with hologram sims. One goes into the issue while the other does not. On the bad board, we can easily replicate the issue by changing to AT&T or traveling around. 

    Here is the hologram trace of it happening. Also note here i did not block any networks (hopefully that will be able to rule that out as the cause of PLMN not allowed.

    Just to verify, does the same application and SIM work on a nRF9151DK?

     any updates on this? Has this been resolved? Did you try probing VDD and verify >3V at all times?

    Kind regards,
    Øyvind
