i use the Polar H10 chest strap on native SFOS for 2 hours, three times a week, every week, and have for years. you do not even need android appsupport, just native linux.
you do not need to login to any app, or even have internet, you can buy an H7, H9, or H10 used or off the shelf, plug it in, and use it, so they can’t take away support for it or anything.
you CAN also use it in android appsupport on sailfish, it works fine just as in android.
here is what works (everything):
- using appsupport:
- changing settings with polar-beat app in appsupport (e.g.: you can enable 2x bluetooth cnxns)
- flashing firmware with polar-beat app in appsupport (i thought this would fail, but it works fine)
- EliteHRV app (not saying its a good app, just that it works and seems to track your HR and HRV correctly)
- in native SFOS (or any linux environment)
- reading bpm/rr values directly over BLE with
gatttoolsandhcitool - works on any linux device that i’ve tried, including sailfish devices, without appsupport
- my fork of BLEHeartRateLogger
- my hrmon script
- reading bpm/rr values directly over BLE with
i use it to log my hr for distance runs to warn me if i’m at too high a hr for too long, and to plot how my hr changes for the same races over time with gnuplot. i also added a toggle in the top pull-down menu to turn it on/off like airplane mode, and also display my current heartrate under the toggle. both of those things require messing about and are not packaged in a clean little app or patch for patch manager, but they are doable.
