Not sure whether anyone else has found a solution but I think I’ve made some progress on this tonight after several frustrating days.
I have a Wahoo Kickr Core transmitting via Bluetooth to a Macbook Pro. Heart rate is separate via an Ant+ dongle.
After using the companion app and having intermittent success I’ve gone back to scratch and firstly tried removing the laptop and just using the Zwift android app on a Samsung S20 which connected immediately and without any issues.
That made me think that the issue was with my Macbook bluetooth rather than the turbo or Zwift.
I loaded Zwift on the laptop and got the dreaded 'No Signal screen when trying to connect.
I went into Bluetooth at this point with Zwift still open and saw that the turbo was constantly being connected and disconnected by the laptop over and over. Very odd!
I then deleted all devices and debugged the bluetooth on the Macbook. Follow these instructions and I’m certain there will be a similar process for Windows:
- Hold Shift + Option and click on the Bluetooth icon in the menu bar
- Click Debug and select “Remove all devices”
- Click Debug again and select “Reset the Bluetooth module”
- Restart your Mac and re-pair your Bluetooth devices
Fingers crossed!! I’ve restarted the laptop several times now and the Wahoo is connecting to Zwift via the laptop without any issues. The Bluetooth icon on the menu bar now has an ellipsis through the centre indicating a connection having gone through the logging in procedure on Zwift.
I’m going to slowly start connecting other bluetooth items such as Garmin watch and headphones and see whether it remains stable but well worth a go.
