IWR6843AOPEVM: How to store frames data and 1D fft data

Tool/software:

Hi,

Following up on point 3 from the previous answer:

You can send out the collected ADC data over UART but real time streaming is not possible. You can store some frames data and send it over UART. Also, you can store 1D FFT data and send only the required data over UART for post processing instead of using the entire raw ADC data. If you need real time raw ADC data streaming, then you will have to use DCA1000.

Due to the fact that the Industrial Visualizer's detected respiratory rate is highly inaccurate (warm-up time 20 seconds, subject at 50 cm distance, error greater than ±5 BPM).

I would like to ask:

How can I store frame data and 1D FFT data on the device, and retrieve it later for custom post-processing?
This would allow me to perform my own analysis rather than relying solely on the GUI output.

Thank you.
