Failed to start bluetooth: passive scanning on linux requires BlueZ >= 5.56

Configuration

I got this home assistant error:

failed to start bluetooth: passive scanning on linux requires BlueZ >= 5.56 with --experimental enabled and Linux kernel >= 5.10; Try power cycling the Bluetooth hardware.

I installed it through docker on a raspberry pi zero 2W

Hello vespuccio,

How is this related to Home Assistant?

If you are trying to run Home Assistant on a raspi zero it is not recommended hardware and will not work properly.

Hi!

I have Home Assistant in docker (2025.3.1) and since 2-3 days the bluetooth devices doesn’t work, with this error in bt integration:
