CSI for Wi-Fi sensing

Hi guys,
I'm newbie in openwrt, and this is my first project :slight_smile:
As far as I understand, the first step to implement wi-fi sensing is to get CSI data
so I want to extract CSI data from my routers
I have two openwrt routers:

  1. QCA9984 ath10k
  2. Flint GL-AX1800
    how can I get the CSI data from them?
    is it possible to get the CSI data using tcpdump pcap?
