I kept seeing people say that bluetooth speakers/mic wouldn’t work directly without gutting them and putting an ESP in them.
Thought it would be an interesting challenge to figure it out as it’s just a basic speak/mic attached to Linux. I didn’t see why it wouldn’t work with the wyoming-satellite etc.
I don’t own any bluetooth speaker/mic combo devices but I had this Bluetooth Transmitter/Receiver for my vehicle which has a mic built in. It also allows you to plug powered speakers into the side and get audio out. I also liked that it showed the name of the device connected on the LCD screen. The mic quality is pretty bad but it worked (I don’t recommend it). Maybe they have made better ones now since this one. They can be found on Aliexpress from any place around $10-$20 and there is quite a gambit of them.
You may have to play with some more Linux/Pipewire settings to get it to autoload reliably but it indeed does work ok.
You need to use Debian 12 “Bookworm” as Pipewire is now default in it. You can use backports with Debian 11 “Bullseye” but why bother.
The bluetooth mic works using Profile: Headset Head Unit (HSP/HFP, codec CVSD) ie you will have lower sound quality than A2DP. A2DP does not allow for microphone use currently.
In researching this topic though I saw where people were adding scripts to profile swap for other purposes but would switch to A2DP while listening to music.
Personally, I could care less about quality and just that it is working for this demo as it sounded ok to me. I did notice the difference though. I saw some interesting things about codecs you could use to make HSP sound better but you had to compile some stuff for flac usage. I didn’t look further into it or maybe I misunderstood what they were talking about.
Installation
Some of these things may or may not be required but they helped in troubleshooting things with some visual representation. They are not needed for a CLI based setup. On Rasbian/Debian 12 most of this stuff is already there so maybe just try it out and hope for the best with no need to install any of this. I’m just tacking it here from a bare-bones look…
sudo apt install pipewire \
libspa-0.2-bluetooth \
pipewire-audio-client-libraries \
pipewire-media-session- \
wireplumber \
bluez \
blueman \
pavucontrol
Note: Most documentation states old locations /etc/pipewire or /etc/pulse for configurations. Currently, all the settings for pipewire are located here: /usr/share/pipewire/ unless you are playing with local user stuff.
Uncomment this extra command module-switch-on-connect should tell pipewire-pulse to autoswitch to the bluetooth audio device when connected. If the device is not an always-on thing not sure if that is 100% thought out. I don’t think there is a wake on bluetooth with most power saving devices 
.
nano /usr/share/pipewire/pipewire-pulse.conf
# Extra commands can be executed here.
# load-module : loads a module with args and flags
# args = "<module-name> <module-args>"
# flags = [ "no-fail" ]
pulse.cmd = [
{ cmd = "load-module" args = "module-always-sink" flags = [ ] }
{ cmd = "load-module" args = "module-switch-on-connect" }
#{ cmd = "load-module" args = "module-gsettings" flags = [ "nofail" ] }
]
This is not required but to clear up some vcp, mcp, bap bluetooth service errors uncomment Experimental=true in:
sudo nano /etc/bluetooth/main.conf
# Enables D-Bus experimental interfaces
# Possible values: true or false
Experimental = true
Make sure this is uncommented as well:
# AutoEnable defines option to enable all controllers when they are found.
# This includes adapters present on start as well as adapters that are plugged
# in later on. Defaults to 'true'.
AutoEnable=true

Note: If HSP is not showing up do not do this for your first time setting up! Unless you think you broke something during setup. It will delete all bluetooth devices that were trusted:
sudo cp -r /var/lib/bluetooth /var/lib/bluetooth_BACKUP
sudo systemctl stop bluetooth
sudo rm -rf /var/lib/bluetooth/*
sudo systemctl start bluetooth
sudo reboot
Add back the device with the directions above.
