AVSystems Cell-Assist localisation broken?

[cellular_iot]

Update: Its still working - I could resolve the issue with ChatGPTs expertise - the nrf Cloud evaluation  key stored in Coiote was older then 30 days... Thats a thing which could go into the FAQs...

Original post:
Hi,

We were basing the development of our new LTE-based IoT device fleet on this webinar https://youtu.be/hh3h5Ow1TmE?si=Fm0LcOy2_zO1XUW6&t=1695 and the avsystems + cell-assist localisation example.


This was working the last months as you can see in the screenshot below showing an old cell-based fix of my daily nrf9151DK:




This week I realized I dont see any location of any registered device anymore. To verify, that not our own changes did break something I did recreate the original setup
- nrf9151DK
- SDK 3.0.2
- nrf/lwm2m_client sample
- extra kconfig fragments: overlay-avsystems.conf, overlay-assist-cell.conf, overlay-rtt.conf (log and shell via Segger RTT instead of UART)
- build and flash


- created a fresh account on AVsystems coiote, setup my ndk
- powered on the device
- coiote shows "device last seen X seconds ago"

below you can see a couple of logs running this sample firmware - it always shows localization errors on the console, coiote sees the device lwm2m-tree, the device' cellid on /4/0/8 but the device never gets a fix and therefore /6/0/* never gets set long/lat values:

Hi,

I tested the lwm2m_client sample using your configuration. When I triggered a location update by pressing Button 2, the cellular location was successfully updated on AVSystem’s Coiote server.

Best regards,
Juha

[cellular_iot]

thanks for testing. Could you please elaborate a little bit more about your setup and environment as a lot of things are not working as expected on fresh Windows 11 installations like debugging etc.pp.

[Juha Y]

My setup: nRF9151 DK, SDK v3.0.2, Ubuntu 24.04. I built the lwm2m_client sample using the same overlays you mentioned in your first message, and tested with two SIM cards from different operators. The sample also works correctly on the nRF9161 DK. Unfortunately, I don’t have access to a Windows 11 PC to test further.

Best regards,
Juha

[cellular_iot]

I did the same and it doesnt. This is the log output of the sample build with SDK v3.0.2, on Ubuntu 24.04 within VSCode and flashed to a nRF9151 DK
