How to send or dump Wi-Fi CSI packet data to my host PC with USB?

Hi all:
I used console to enable Wi-Fi CSI function.
But I have no idea about how to send or dump Wi-Fi CSI packet data to my host PC with USB when CSI callback function returns CSI packet data everytime.

The USB you mention is in all probability a serial-to-usb converter on your devboard. as such, you can just send it over your serial port (printf?) in some format (suggest binary or base64-encoded) and write a program PC-side to grab it off the emulated serial port.

Could you give me an simple c code example on esp32 side and PC side(if we use fwrite() to send binary data to PC )

No, sorry, I'll leave that up to you.

Hi,

If you are interested I recently did it : https://github.com/jonathanmuller/ESP32 ... ation-CSI-
It logs 802.11n frames as well as CSI from the ESP32 to a linux running PC
