Arduino UNO Q freezing up?

Official Hardware UNO Family UNO Q
1

I have a working app with a connection to Arduino Cloud. It sends data from the board to the dashboard. I kept it online for about a week now. But now I discover that 3 days ago, the app does not register any values anymore.

I can access the board over the network with App Lab, but I don’t see anything in the monitor/serial. I restart the app, but nothing. Als starting new apps with logging does not show anything in the monitor. Only after connecting the board using the USB cable to the laptop and then restarting the app, the app shows logging and also values again in the cloud dashboard.

When I go to the Arduino Cloud and look at the device, nothing from the past week is logged in the device status history. Also, the webpage in Arduino Cloud for device status freezes.

Weird… Is the Arduino not made for long-term online?

Does it make a difference if you close App Lab and then run the following command from the Q command line?

arduino-app-cli system cleanup

Then restart App Lab and try to run your sketch again.

I will try this the next time this occurs. Thanx.

Hello,

Again, my board freezes and also App Lab. So I tried this, but it does nothing…

It shuts down the running app. When I start the app, it still does not work anymore.

And also when I stop the app in App Lab and then restart the app, it does not work anymore (App Lab says the app is started, but nothing in serial monitor or the Arduino Cloud Dashboard)

Hi @RobertvdBerg.

Do you encounter the same problem if you run the "Blinking LED from Arduino Cloud" example App?

I have started the app now and I will keep it active a couple of days.

So after 2 days, “Blinking led” is still active and the UNO Q is not freezing up.

Maybe the recent update made the UNO Q more stable.

I turned on my custom made app, let’s see how it goes for a few days.

*update*

@ptillisch After starting the Arduino (which also starts my custom app), I opened App Lab. I can open every app and look in the readme or python/sketch. But when I open my running app, AppLab freezes and I can only close App Lab. Why? (Or better: how can I investigate what the issue is / what is happening?)
