Connect Elite Muin Turbo B+ with Zwift over Bluetooth

Hi

Recently I bought the Elite Muin Turbo B+ and I want to connect it with Zwift over Bluetooth.
The Misuro B+ has been placed in the right place.
I bought a Belkin USB 4.0 Bluetooth adapter which recognizes my Elite Muin Turbo B+ trainer.

But if I start the Zwift application on my computer, he still refuses to find any data (even If I’m biking).
" No ANT+ dongle found".

Second try: 
I tried to connect my (old) ANT+ dongle from my Garmin 310XT.
My watch transfers all my data from my watch to my computer.
But still there is not data found when I want to connect my bike.
I think this stick is too old for this application.

Do I really need to buy a ANT+ dongle or I’m doing something wrong with my bluetooth. (my mobile reads all data correct from bluetooth)

Thanks in advance

Hi Ruben,

If you wish to connect devices to Zwift via Bluetooth, you must enable to Bluetooth Beta promo and use an iOS device as a bridge as detailed here: https://support.zwift.com/hc/en-us/articles/206576683-Bluetooth-LE-BLE-Support

The ANT+ dongle needs to be USB 2.0 - your old one probably is not this.

Thanks!
