Modem Reset Loop With Asset Tracker

[mmelv]

Hello,

I'm running into a problem where every time I run the asset tracker the modem reset loop is triggered and I have to wait 30 mins before I escape. I've read the modem reset documentation https://infocenter.nordicsemi.com/index.jsp?topic=%2Fnwp_042%2FWP%2Fnwp_042%2Fintro.html but I don't know how I'm supposed to avoid this problem. The terminal output doesn't indicate that the modem is resetting 7 times (unless it's happening to fast). I've been working with the asset tracker for a few weeks now, I've encounter this problem before but it usually goes away, but now it's persisting. 

Also I was previously able to circumvent the 30 min timer by using the nRF Desktop Programmer tool to erase everything, then do the AT Command quick start to get the modem running again but this also no longer works.

Any help would be greatly appreciated!

Everything works fine on my nRF9161 (0.9.1) but it doesn't work on the nRF9161(1.0.0). I tried doing the programmer when I didn't start in the reset loop and it still didn't work. I'm not really sure where to go from here.

Hi,

Can you elaborate on what you tried and what did not work?

Best regards,

Yes.

1) Waited until I escaped reset loop

2) Erase all with programmer (auto reset disabled)

3) AT Command quickstart

4) Erase and flash application (also tried just flash)

I still entered the reset loop on boot. It seems to go away after less than 30 mins though.

Hi,

Is "AT command quickstart" part of the Quick Start procedure available from nRF Connect for Desktop? 

How did you perform "Erase and Flash" and from where?

Best regards,

1) Yes, the AT Command quick start.

2) I used the erase and flash from VS Code.

Thanks!
