EZWIFI

EZWIFI is an ESP32 component for setting up Wi-Fi and collecting channel state information (CSI) from received frames.

Usage

A node is configured as either an access point (AP) or a station (STA):

// Configure this node as an access point
setup_softap();

// ...or as a station
setup_station();

// Enable CSI collection, filtering on the sender's MAC address
setup_csi("AA:BB:CC:DD:EE:FF");

Once running, is_wifi_connected() reports connection status, and get_csi() returns a pointer to the most recently received CSI frame.

if (is_wifi_connected()) {
    wifi_csi_info_t *csi = get_csi();
}

This was originally built for a two-node presence/activity-detection system, where one node ran as AP and the other as STA.
