Description: I have connected the polar verity sense with the polar ble sdk but when I click on start HR stream button on polar ble sdk app. I do get HR (bpm) data but I am not getting rr value. How do I stream rr values for polar verity sense using polar ble sdk app?

Hi, RR is the interval between two R-peaks : That curve is an electric signal that is emmitted by the heart and that can only be measured with ECG (strap based sensors like H9,H10).

Verity Sense is a PPG based sensor so RR interval is not available. You can get PP intervals which is a similar beat-to-beat representation, this article talks about these 2 more in detail. For that you need to use startPpiStreaming() API
