IWR1443BOOST: The output data format of High Accuracy Range Measurement demo on IWR1443BOOST

Hello,

How can we know the detail of the output format of the High Accuracy demo on IWR1443?
We could get the data via UART from IWR1443BOOST; however, we cannot understand what the data mean.
In case of Out-of-Box-Demo, we can find the data format in the document of SDK and we expect there is a document like that.

Best Regards,
Nomo
