In ESP-IDF guide: https://docs.espressif.com/projects/esp ... nformation,
ESP32 Wi-Fi can get CSI (channel state information) data.
But which 802.11 frame type can ESP32 Wi-Fi get it's CSI (channel state information) ?

Could ESP32 CSI (channel state information) be received from 802.11(b) beacon, control or data frame?

Hi All,
Is it possible that I write an event while loop in app_main() so that it can change Wi-Fi mode between STA and AP mode due to event value after flash the build image to EPS32?
How to use EPS32 these Wi-Fi driver API to programming?

If we use RF switch to implement multi-antenna selection, how do I do to connect ESP32-WROOM-32U to RF switch?

What are Wi-Fi Tx/Rx pin numbers for ESP32-WROOM-32U Wi-Fi Tx/Rx pin numbers?
I cannot see from data sheet.

Does ESP32 Wi-Fi HW supports 2 Rx chain to get 2 Rx CSI datas?

Does ESP-IDF has API that we can send buffer data to my hosts machine with USB interface?
For example, on ESP32 side, we would like to use its Wi-Fi connection to get an AP MAC address and use USB interface to send the binary data of the AP MAC address to my PC.

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 )

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.
