    Hello Anto,

    The register settings and the waveforms that you had attached did not come through.

    Can you please attach them again?

    I am not an expert in the mechanical design to offer any recommendations on the wrist-sensor distance.

    Typically we have noticed that the watch must be worn snug-fit and not too tight to get quality PPG data.
