can esp32-c6 get CSI of wifi APs around without connected (sniffer mode)?

[junfeng]

hi,

I want to receive csi of wifi APs around in sniffer mode, i.e. not connect by username and password.
I found that:
- csi_send/csi_recv support send/receive by both esp32 board,
- csi_radar need to connect to router by username/password.

is there example to receive csi of wifi APs around in sniffer mode (not connected) please?

thank you.
