AVL stops sending data /GPS stops working on RUTX50

Hi,

does anyone know if there is a bug fix for the current RUTOS not sending data to the AVL recipient anymore?

I already have a daily restart of the router, but unfortunately the reporting of the position stops sometime during the day without any visible error message.

In the logs I do see some kernel warning, after the last AVL message was sent:

Mon Sep 18 12:48:14 2023 daemon.info avl[4915]: Sent data to server

GSM is still available after the fact, but the map on the device only shows the old location as well.

Any ideas?

Hello,

The logs indicate an issue with the modem which is responsible for both, the mobile LTE/5G connectivity and GNSS. This can also be caused by other factors.

The first thing I would recommend is to reinstall the firmware following the bootloader procedure described here. After that, try configuring only the most necessary settings.

In Services → Auto Reboot → Ping reboot, configure a rule to reboot the device when pings fail (information here).

In System → Administration → Troubleshoot, make changes to save logs in flash memory. This way, the logs should persists after reboots.

It would be great if you could provide more system logs right after the issue occurs again (if it occurs).

Kind Regards,

Hey AndzejJ,

thanks for the response, reinstalling the firmware needs to be delayed a bit, as I am currently on the road and lacking a possibility to use wired networking :slight_smile: , I’ll do it later.

I activated the ping reboot and logging to flash, let’s see what happens.

Cheers,

Tobias
