About the csi phase #105

Open Worange12 opened 5 months ago

Worange12 commented 5 months ago

Can I get the phase difference buy just one antenna on ESP32-S3? And the csi data of https://github.com/espressif /esp-csi is that the singular column is the imaginary part, and the even column is the real part, how about this project?

This code shows how Raw CSI is generated as well as how to calculate amplitude and phase based on the order of real and imaginary components. https://github.com/StevenMHernandez/ESP32-CSI-Tool/blob/master/_components/csi_component.h#L61-L78
