• ok similar to the last time I did the following small test with each part for approx one minute:

    1. sitting still
    2. walking slow
    3. walking fast
    4. running without moving
    5. sitting still

    Result is bt chest belt in blue, firmware 2v17.55 in green, firmware 2v17.56 in sports mode in red. X-Axis is hrm event count (~1 second), y-axis is BPM.
