HF ist constantly 0

Since ANT+ doesn’t work, I got a Bluetooth smart 4.0 HF belt. It connects instantly, but always shows 0 bpm. With other apps (e.g. bkool), the heart rate is displayed correctly, so I guess it’s not the fault or e defect of the belt.
It is a Powrx Bluetooth low energy HF belt.

Hey Beau, sorry to hear Zwift is not connecting your with your HF belt. :frowning:
