You're rather late... Bluetooth was deprecated in 2018 for
QEMU v3.1 (hence that warning message), and was subsequently
removed entirely for QEMU v5.0, released in 2020.

The code in QEMU was, as far as we could tell at the time,
basically unused, unmaintained and also broken. It isn't
coming back, I'm afraid.

Do you have an existing application that runs and works with
the bluetooth functionality on the QEMU version you have,
or are you instead trying to get it working as a new thing?
If the former, the answer is "just keep using that old QEMU".
If the latter, the answer is "it never really worked anyway,
so don't bother trying".
