Hi
The onboard BT on my Pi4 only has a range of about 6-9ft, so instead I use a BT dongle on an extension lead which subsequently gave me excellent range in my home.
Before I installed the dongle the BT available was:
HCI0
After installation, the following were available:
HCI0
HCI1
For some reason the dongle BT was automatically defined as the (default) HCI0 rather than 1, but I set it up with the Bluetooth Integration (2022.8) and it worked fine until today.
Today my BT device(s) were unresponsive and in the end it was resolved with a simple reboot.
My concern is that HASSIO might be randomising the BT default assignment on start-up and maybe I’ve just lucky so far that the default HCI0 has stayed as the dongle.
It shouldn’t be, but in case it is I’m looking or a way to disable the on-board BT so that this is guaranteed not to happen.
What I tries so far:
hclitool and hcliconfig don’t work within HASSIO OS
rfkill help does work, but rfkill list isn’t allowed, even with SSH protection disabled
bluetoothcli does work so I selected the onboard bluetooth and tried bluetoothcli agent off
and bluetoothcli power off on the onboard controller, but it didn’t seem to do much of anything.
I did find some useful information on this page, but udevadm and the “/etc/udev/rules” path don’t exist in HAOS
Any help would be appreciated.
