AWR1642BOOST: What are the breathing rate and heart rate values in the driver vital signs lab uart package?

Part Number: AWR1642BOOST

Hi, I am using the driver vital signs lab with the automotive toolbox 3.0.0, I am interested in getting these values

in the developer`s guide, you provide the uart package format but I don't know which of these values represents the breathing and heart rate

So, are these values obtained directly from the package, or are they calculated in the Matlab application?, If so, is there any additional documentation provided to understand how to calculate them?, thanks

    Hi,

    You are correct. The target code does not provide the final value for the breathing rate and the heart rate. The target code computes several estimates and confidence metrics and send them to the gui. The gui selects based on confidence metrics the final decision value.

    Please see Slide 7 for a block diagram of the decision process.

    Please review the gui code on how the decision is made (it is a qt based gui not matlab). Please use Automotive Toolbox v 2.9.1 or earlier
