Wave not connecting with an external bluetooth dongle

Hey people,

I'm using Wave in dance/music -performances and trying to increase the range and make the connection a bit more steady with movement. I found a Sena Parani UD100 -bluetooth adapter with a patch antenna, which seems to increase the bluetooth range quite a lot (a lot more bluetooth device -options showed up when I got the antenna working). For some reason, Wave doesn't connect to Softwave when I change to the external antenna. My phone for example connects without a problem. What could I try next?

If you have experience of long range antennas that work on Mac (I'm using a 2018 MacBook Pro), I'm all ears.

Best,

Kalle
