Logger HR+RR for Polar H9+H10 Bluetooth 3366ff Reads data from Polar H9 or H10 (Bluetooth Heart Rate Service) Probably it also works with other BLE HR sensors that provide RR-intervals. Data: Heartrate, RR-intervals (RR1 .. RR4) Packages of 4 RR intervals are accepted, works up to an HR of 240 BPM Reads status of battery as percentage Shows values on screen: Timer Unit seconds HR (unit BPM) RR1 .. RR4 (unit ms) Flags (status of HR sensor - 16 means that valid RR packages are sent) Battery status Graph: HR as function of time RR1 as function of time Note 1: The graph will sometimes show points with RR-intervals of zero. This happens when the HR is below 60 because not every second an RR-interval is transmitted. Note 2: If you want, you can add also the RR2..RR4 intervals, but that will make the graph more messy.
