i have an HP-15-da1016 laptop with rtl8822be wifi and bluetooth combo hardware
wifi is detected and working perfectly
bluetooth is not detected
lspci
gives nothing about bluetooth while clearly deteccts wfif
was the bluetooth detected in your case
i.e when you did lspci the output stated that there is a bluetooth device ?
in my case the hardware is never seen.
although it works under widows ok
the aqetical you have sent me deals more with a detected blurtooth device
I don’t really remember, it was a couple of years ago. It may have been the way @fasulia said - run bluetoothctl and see if it is picked up. If neither the system nor bluetoothctl sees it, there isn’t much software can do for you.
