I'd be curious to hear what the challenges are. Is it simply that signal strength is too noisy to be used reliably? (I.e., interference, multipath, attenuation when the subject walks behind furniture, etc.) I was attending a theatre show a few days ago, and thought that the sound system could deliver a better experience if the positions of mics on stage could be tracked as cast moves around, and the mixing adjusted accordingly. Naturally, BLE was the first thing that came to mind.
