I'd like to be able to continue talking to people nearby (typically, no more than 3m. away) in normal tones, rather than having to shout, when ambient noise levels become too high for normal conversation.
If I've correctly understood the Bluetooth protocol, it should be possible to pair, say, two inexpensive Bluetooth headsets with a Raspberry Pi which runs the software necessary to make the audio connection between the two headsets.
Unfortunately, I've no idea how to realise this ambition. Can anyone help?
Best wishes.
