Hi,
I was wondering if the following can be built using bluez. I would like two or
more people to communicate in something like a voice conference while wearing
BT headsets.
I imagine that one can connect multiple BT dongles to a PC and pair each
headset with one dongle.
As far as I know ALSA can be used to setup the audio devices. Likely a
soundserver such as JACK2 can be used to manage the audio routing.
Is this the right path ? Or is there another/better way to establish a voice
connection between multiple headset units ?
Any pointers are appreciated.
Sebastian

Hi Sebastian,
Newbie here: I have (very briefly) attempted to do something similar
and it was suggested to me that ofono, which is a higher-level API on
top of BlueZ, was a better starting point.
Hope this helps.
Cheers,
David

There is a lot of confusing information out there on the web. It is hard to
judge what is current and what is outdated.
Seems like there were a number of changes over the years. It looks like HFP is
currently only supported by ofono while HSP is supported by both
Looks like Pulseaudio is a big part of this.

Bluetooth/
People seem to recommend JACKaudio for low latency audio

In other words I would have to access the headsets without PulseAudio.
There is something called alsa_in/out which potentially takes care of this.

Best,
