IWR1642BOOST: Pls. kindly help to check the attached steps, the heartbeat test is failed.

Lian,

Please make sure that you have the board oriented correctly so that it is aimed directly at your chest per the instructions in the Developer's Guide. You should use the bracket mounts that are included with the EVM so that the EVM can freely stand on its own. Holding the EVM in your hand can introduce vibrations that can affect the measurements and thus result in inaccurate information.

Please also keep in the mind the processing chain for this uses a window of previous measurements in order to smooth out the instantaneous measurements to provide more accurate information. As stated in the Developer's Guide, it can take approximately 16 seconds to adjust and calibrate to a test subject. Given that your video is only 14 seconds in length, you can not allowed the requisite time to pass in order for the sensor to adjust to your body motion.

I would not classify this as a failure since the lab is functioning as intended. I will consider this thread resolved and close out this ticket.

Regards,
Kyle
