We do have a freeze detection (like you say AlphaHRV freezes often) but seems like we should improve it since this activity evades it. Could you please send me the fit file to markus@aiendurance.com ? Thanks!
I have a forerunner 965 and the hrm pro. If connect the hrm to the watch with ANT+, I get the advanced running analytics, which I want, but I lose precision on the HRV data. It’s a Garmin quirk. So i use alpha hrv app to connect the hrm to the app with Bluetooth which add a second, precise, feed of hrv data to the fit file.
If I were to connect the hrm band to the watch with Bluetooth, I would have a precise feed of HRV data and wouldn’t need the app, but I would lose the advanced running analytics.
So I connect the hrm band to the watch with ant+ and also connect the band to the app on the watch with Bluetooth.
