Heart Rate Variability (HRV) measurement Charge2

[jeffbrandt]

Does the API or will the API provide heart rate variability (HRV) information?

@jeffbrandt HRV is not stored anywhere, it's only part of Charge 2's "Relax" feature. So since HRV data is not tracked (like steps, distance, HR, etc.), then you won't be able to pull that information.

thanks,  Just checking

Not good answer.

HRV is a calculation. Time between two beats. 😉

Not stored, that's correct, but if you have the heart rate in a high sampling rate, you can calculate the HRV!

Is that possible with the SDK?

I guess no. Am I wrong?

The time of individual beats is not recorded. The highest resolution data is BPM sampled every 1 to 3 seconds (or longer on older devices if not in an activity session).
