I’m transitioning from hassbian on a rpi3 to hassio on a rpi4. Trying to build my own Bluetooth LE add on but simply cannot get simple things such as hcitool to work on the root shell. Seems like the hardware isn’t recognized at all. I’ve been looking all over the internets but haven’t found any remedy yet. Is Bluetooth supposed to work on hassio running on a rpi4?
I don’t think Bluetooth is working on hassio at all, as you say it doesn’t seem to be able to find the hardware, in spite of the hardware working fine if you use it in a different container.
There is a github issue open about it, but iirc nobody from the dev team has looked at it.
