[Bug]: Raspberry PI 3 - HCIdump thread: Something wrong - interface hci0 not ready, and will be skipped for current scan period.

[EndermanAPM]

What happened?

Every time I boot, the bluetooth works for some time until it doesn't. Doing a full reboot fixes it for some time.
I observed that some versions of HA seem to have longer intervals between flatlines. Right now I'm rebooting twice a day at least.
Also I'm running standard Home Assistant OS with no tinkering.

Sensor type

No response

Try to enable active scan for BLE monitor, if you use passive scanning right now. Or the other way around if you use active scanning right now (if your sensor don’t require active scanning of course).

The aim of this is to make BLE monitor to use the same type of scanning mode as the Bluetooth integration. HA doesn’t like two different scanning modes, as it would have to switch back and forth, which can cause issues like you observe.

[perseus177]

Currently I have enabled Active Scan with problems.
I will try to disable Active Scan and I will go back with result

[perseus177]

@Ernst79, change active scan did not help

Any update ?

[EndermanAPM]

I "fixed" the issue by upgrading to a Pi5. So perhaps it's a hardware issue with the PI3?

[perseus177]

Hi @EndermanAPM I have also RPI4 in second flat and it is working without problem, but fix the issue as buy different hardware is not a fix. This issue has in name and description that problem is only o RPI3

[EndermanAPM]

Hi @perseus177 I know that, I'm the OP! 😄 But perhaps eliminating variables can help the project maintainer pinpoint the issue?
Now we know that the PI4/5 works fine, and I've heard that the PI3 with an external BT adapter works just fine. So at least we can be pretty sure it has something to do with the build in BT adapter of the Pi3.

p.s. Looking back, my comment perhaps was poorly worded and I apologize.

[CloCkWeRX]

Suggestion, downgrade this to a warning rather than error.
Also seeing this on a HP mini device, so it's more about the hardware/not much this integration can "fix"

[LeoColman]

I confirm that I am also getting this problem.

It seems to happen when more computing is going on with the PI, and the adapter never comes back up (even with 'restart on failures' enabled). I'm using an external Logitech Bluetooth Dongle.

Same flatline after a few hours (sometimes minutes) booting

This wasn't happening 6~ months ago. Same hardware.

---

Sometimes, changing the Bluetooth dongle port is enough to fix it for 3~5 days before it flatlines again
