Bluetooth enabled, causes constant writing to disk from bluetoothd process #76540

jeff903405 · 2022-08-10T01:04:21Z

The problem

After upgrading to 2002.8.2 and enabling bluetooth I started seeing constant disk writes from /usr/libexec/bluetooth/bluetoothd I disable bluetooth module and the disk writes stop. With bluetooth enabled I then disabled the Govee devices and the disk write still were occurring.

I am not seeing this issue with Bluetooth Low Energy Monitor.

What version of Home Assistant Core has the issue?

2022.8.2

What was the last working version of Home Assistant Core?

Hey there @bdraco, mind taking a look at this issue as it has been labeled with an integration (bluetooth) you are listed as a code owner for? Thanks!

Can you get an strace -f -s4096 -p <pid> of bluetoothd to see what its doing?

Sure here is a trace running for a few seconds... let me know if you need more...

Seems like a bug in bluetoothd

I'd suggest opening an issue with bluez

jeff903405 · 2022-08-15T16:16:35Z

ok I will get onto the newest bluez first since I am running several version behind... Then I will re test and see if it continues...

Please open an issue with bluez. There isn’t anything Home Assistant can do about the system Bluetooth stack.

pvvx · 2022-11-04T10:12:29Z

How to disable "active scanning"?

If active:

All connected BLE devices are scanned in active mode:

This drains the batteries of the BLE sensors and bluetoothd overwrites the scanned device names.

bdraco · 2022-11-04T10:23:51Z

Please read the documentation
https://www.home-assistant.io/integrations/bluetooth/#passive-scanning

pvvx · 2022-11-04T14:04:26Z

Bluez 5.65, enable 'experimental'

# bluetoothctl --version
bluetoothctl: 5.65

Home Assistant 2022.11.1

This option enables or disables writing /var/lib/bluetooth/xx:xx:xx:xx:xx:xx/cache files to disk and active BLE scanning.

When "active scanning" is disabled, "BTHome" does not work, but "Qingping" and "Xiaomi BLE" work successfully.
