I just copied a request from the old forum, because I still want it:
"Description of bug/feature request/question:
It would be great to control my Mac with iPhone BTT Remote via bluetooth. One particular use case is presentations in foreign environment (phone and computer are not on the same wifi / wifi does not work etc.)
Affected input device:
BTT Remote on iPhone"
Link to the old request: https://github.com/folivoraAI/BetterTouchTool/issues/747
Lets make it happen to be able to control our Mac just with our iPhones without the need of having wifi!
