HassOS 4.14 in RPI3, BT not working

Hello,
The BT in my RPI3 running 4.14 seems not to be working (at least I have lost the connection of all my Xiaomi LBTE devices - which used to work fine using this integration).

It started happening yesterday, I believe that at the same time that following this post and running:

nmcli radio wifi off

I disconnected the wifi. I have tried to enable it again, but the Bluetooth continues without working.

If I run:

bluetoothctl

it gets stuck with the message:

Waiting to connect to bluetoothd

I have tried to enable the bluetooth using the RPI command:

systemctl start bluetooth 

but systemctl is not available.

Any ideas? I have tried the solutions in this post Thank you very much

Try updating to 4.15? https://github.com/home-assistant/operating-system/releases/tag/4.15

Newby question, how do I update? I have tried with ha host update and ha core update and nothing. In the director I don´t have the update option available :frowning:

Thanks!

ha os update --version=4.15

ha help if you want to browse what’s available

Or go back to 4.13 ha os update --version=4.13

Thank you. 4.15 worked.
