IWR6843AOP: Vital Signs demo performance

Part Number: IWR6843AOP

Hi,

We are testing the vital signs demo and the one included in radar toolbox version 1.30.01.03 gives us inaccurate readings of the heart rate, usually it is between 52- 65 BPM, most of the time being around 55 BPM, while the actual value is around 75-80 BPM. We also evaluated an older version, the mmwave industrial toolbox 4.10.0 and it gave us much better results, most time being around 75 BPM. Why is that the demo from the newest toolbox yields us a much worse performance? 

Best,

Tomasz
