RR_INTERVAL is the time between two consecutive R-waves (R-peaks of consecutive QRS complexes), typically provided by chest and arm straps alongside heart rate.

For real-time streaming:

• Generic BLE devices mainly broadcast heart rate (plus RR intervals when the device permits).

• Speed, distance, and calories during workouts are only streamed from Apple Watch and WearOS smartwatches.
