Outdoor Monitor crashing - Core 0 panic'ed (Load access fault)

#1

I’ve just received my O-1PST, but after only a few hours it can no longer stay up for more than 30 seconds.

The logs repeat this forever, I hope it helps you diagnose the issue:

Can you please flash the latest beta firmware Version 3.0.10Beta 2
Available at the bottom of that page.
https://www.airgradient.com/documentation/firmwares/

Then please let me know if that fixes it.

It no longer boot loops, but it also no longer posts data to the server?

[ApiClient] Warning: Ignore post data to server
[Configure] Info: Parse configure success
[Configure] Info: Set co2CalibrationRequested: 0
[Configure] Info: Set ledBarTestRequested: 0
[Configure] Info: {"country":"AU","pmStandard":"ugm3","ledBarMode":"off","displayMode":"on","abcDays":8,"tvocLearningOffset":12,"noxLearningOffset":12,"mqttBrokerUrl":"","temperatureUnit":"c","configurationControl":"both","postDataToAirGradient":false}

I see "postDataToAirGradient":false

#4

Reading more about the Local Server Documentation - I set {"postDataToAirGradient": true}, but it returns to false on reboot. I can’t see any sort of “commit” operation.

I also tried setting {"configurationControl": "cloud"} and get the reply Local configure ignored , but when I GET /config, it just shows it as "both" still.

At any rate, with the manual override of {"postDataToAirGradient": true}, it seems to be reporting again. Was the crashing a known issue?

#5

Yes the crashing was a known issue caused by the led_off setting. We are also aware of the post to server issue in the beta version.

We are in the last stretches for the next release and hopefully these things will be fixed.

#6

Excellent to hear! I look forward to the full release.
