I'm getting the same thing.

Not sure if #11284 will make this invalid or not.

[forrestjr]

Do you guys know how we can test to see if BT is working from HASSIO or not?

[tehbrd]

Refer to my post above forrestjr

hciconfig / hcitool lescan should be able to run both those from the host or the guest (homeassistant docker)

In regards to my issue, it went away with a reboot and reappeared on another restart.

[tehbrd]

I was just replicating my issue when I noticed upon reboot hci0 was down. Althought this wasn't the case above.
