Hi Paul, welcome back. This is Juan from Zwift. I understand how essential it is for you to maintain a stable connection with your heart rate monitor. Don’t worry. Let’s bring you back on track.
Dropouts are often difficult to pinpoint. Troubleshooting may vary depending on how you are paired, Bluetooth or ANT. Please refer to this article to get ANT+ and BLE overview.
Bluetooth, unlike ANT+, is a one-to-one connection. Your heart rate monitor may be paired with another app or device. On the other hand ANT works differently. Weak signal or interference is by far the most common reason for ANT drops and is due to the inherent weaknesses of ANT+ as a wireless protocol.
I’d like to suggest you take a look at this article to rule out scenarios and isolate the issue. There you also find suggestions on how to fix each one. If the issue persists, please don not hesitate to contact our support colleagues. We will be delighted to help you.
