I have a Bluetooth Polar H10 heart rate monitor, which is correctly detected by both my training machine (Kettler Skylon 3.1) and the Kett Maps app. In the app - my equipment - it shows the heart rate.
When I start a workout, the machine shows the heart rate, the app shows the sensor (and my IPad tracking camera), but during the workout, the heart rate is not displayed and stays at 0.
At the end, the workout is posted to Strava, also without any heart rate.
I tried both discovery and challenge mode, same result.
What could be the issue?
