Tizen heart rate monitor rRInterval

In the Tizen Heart Rate Monitor (HumanActivityHRMData), is the value rRInterval the time of the most recent interval (and updated every heartbeat), or is it a rolling average of the last several heartbeats?

All the documentation says is:

readonly long rRInterval

Peak-to-peak interval in millisecond(s).

I'm trying to develop an app that needs a lot of precision in pulse detection, and a rolling average isn't precise enough.

Solution

  • If you are talking about HumanActivityHRMData I'm assuming you are trying the Tizen 2.3 version.

    I have tested HRM on 2.2.1.x (which is running Gear S) and the rRInterval (MotionHRMInfo) data has appeared on every beat, so I think it's the most recent interval.

    This should be the same on the newer version, but there is no hardware to test it for now.
