I got an error when I tried to configure using menuconfig as well as when trying to build the Capture_CSI
Here is the error:
CMake Error at ../../../../tools/cmake/component.cmake:475 (add_library):

Could you please help with that?
Thank you in advance.

Hi,

Thanks you for the interesting paper.
I am currently using nexmon_csi tool to extract CSI information, and I find your solution very interesting.

Can you please explain why the phase from esp32 is not random while in others it is random?
I have looked at the phase figures, I am not sure I was able to recognize a pattern (same goes with nexmon_csi).

I am referring to this quote:
"The amplitude and phase values received From the entire set of subcarriers can provide precise CSI values useful for various DFWS applications. The other existing CSI tools have random phase values from CSI and need correction for DFWS applications. The phase values received from all sub-carriers also show different signal strengths, enabling them to be used for different DFWS applications based on requirements."

Thanks,
Tomer
