IWR1443BOOST: What data to send over SPI line to get only range data

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: CC2650, TIDEP-0091, AWR1642

Hello,

My team is struggling to only extract the 1D range data from the out of box demo for the iwr1443Boost. We want to only send the range data over our spi line to be displayed by a cc2650 launchpad via bluetooth. We currently have spi functionality between the iwr and cc2650, but are struggling to figure out what data to send over. As of right now, we belive that the range data is stored in the rangeDopplerLogMagMatrix, but from the documentation, it also seems that this is an output of the 2D FFT, which is confusing us. To get our range data in mm, what is the structure that we should send over? How should we modify this structure so that we only get the range data and not the velocity or elevation of our object? Are we correct in our assumption that we need to send over the rangeDopplerLogMagMatrix?
