Making Bluetooth pairing persistent?

[steveu]

I'm struggling to track down some interference on the physical audio output from a Rosetta, but one work around would be to use the Bluetooth out into a Microavionics interface.

However, Bluetooth isn't persistent as we have discussed before.

How much of an issue would it be to make Bluetooth pairings persistent?

I had issues with interference with the audio output on my PAW when I was using a cable from the audiojack and I was advised, I think by the people on here, to fit a Ground Loop Noise Isolator like this https://www.ebay.co.uk/itm/Ground-Loop-Noise-Isolator-Filter-3-5mm-AUX-Cable-For-Home-Car-Stereo-Audio/143632997640?epid=14022520569&hash=item2171319d08:g:UYMAAOSwHktfSgia, which completely solved the issue. Worth trying for a fiver?

Already tried it, no signal, so assume the isolator is duff, and need a work around until I can try a different adaptor or fault find/prove the one I already have.

Other reason is to use a clever BT device that can receive two streams to inject into one port on the Lynx intercom.
