bluetooth connection turbo muin b+

[mandusoju]

Hello,
i have been using my turbo muin b+ for few years now, connecting it
to Zwift by an ant+ usb stick. This setup progressively gave me more
an more problems in trainer detection by Zwift. Last time i used it, i took
45 minutes of fiddling around with the stick, switching on/off the trainer
and rebooting Zwift, before it was able to connect with the trainer.

During that time I wondered how to connect the trainer by bluetooth
instead of ant+. Zwift links immediately to my heart sensor and powermeter
via bluetooth but it never saw the trainer. I wonder if there is anything i
need to do to activate bluetooth on turbo muin or it should be automatically
on, thus malfunctioning in my unit.
Thanks a lot,
Simone
