thank your response.

I run the python guy. it didn't display any csi or rssi curves without connected to router.
it did display csi and rssi curves after connected to router by username and password.

thank your reply, I checked the get-started examples:

csi_send and csi_recv works together where csi_recv get the csi_send's csi specifically. not in sniffer mode. I run csi_recv without csi_send and got nothing.

csi_recv_router get connected router's csi but not in sniffer mode.

Hi,

I am to develop wifi based location by csi per AoA method. It need multiple antenna's csi. How many antennas is on ESP32-C6-DevKitM-1 and do these antennas positioning for wifi AoA requirements (6.25cm for 2.4GHz's half wave-length)?

if not, how to connect external antenna matrix to the board ...
