Pass HCI bluetooth to LXC container

[pszafer]

Hello,

I've read a lot topic, no one with any way to solve the problem (maybe still impossible).
Is there anyway I can pass bluetooth HCI to LXC container?

I don't need this BT in host.

Tried like this:

lxc.cgroup.devices.allow: c 189:131 rwm
lxc.mount.entry: /dev/bus/usb/002/004 dev/bus/usb/002/004 none bind,optional,create=file

No success, bluetoothctl no returning anything.
