Connection to USB GPS lost after running for a day

[scsirob]

Yeaterday I received my bridgeboard and built the PilotAware system using the latest image. All seemed to work OK, except it suddenly lost GPS connectivity. The system log shows what appears to be a resource conflict. Unplugging and re-inserting the USB GPS resolves the issue (for now).

I presume you are keeping your device up in order to monitor from the OGN-R station.
did you have an http browser connected all the time it was running ?

I have occasionally seen some issues when a browser is connected for a long period of time, particularly on things like the traffic page.

Thx

That is correct. I had the radar screen open all the time and I was curious to see how it interacted with the OGN-R node.

My stats on the PAW clearly show they see eachother well:

Let me know if there's anything I can do to help diagnose.

Hi Rob
Was it only the radar screen, I will try to reproduce
Thx

Hi Lee,
I only had the radar screen active. There was a big yellow button in the top rh corner of the radar, labelled "GS-OGN 1", I guess that was due to my OGN node being active? Not sure if that station right on top plays a role.
