Wi-Fi
Introduction
The Wi-Fi libraries provide support for configuring and monitoring the ESP32-C2 Wi-Fi networking functionality. This includes configuration for:
Station mode (aka STA mode or Wi-Fi client mode). ESP32-C2 connects to an access point.
AP mode (aka Soft-AP mode or Access Point mode). Stations connect to the ESP32-C2.
Station/AP-coexistence mode (ESP32-C2 is concurrently an access point and a station connected to another access point).
Various security modes for the above (WPA, WPA2, WPA3, etc.)
Scanning for access points (active & passive scanning).
Promiscuous mode for monitoring of IEEE802.11 Wi-Fi packets.
Application Examples
Several application examples demonstrating the functionality of Wi-Fi library are provided in wifi directory of ESP-IDF repository. Please check the README for more details.

1. Mask can be created by logical OR of various WIFI_EVENT_MASK_ constants. Events which have corresponding bit set in the mask will not be delivered to the system event handler.
- Attention
2. Default WiFi event mask is WIFI_EVENT_MASK_AP_PROBEREQRECVED.
- Attention
3. There may be lots of stations sending probe request data around. Don’t unmask this event unless you need to receive probe request data.
- Parameters
mask – WiFi event mask.
- Returns
ESP_OK: succeed
ESP_ERR_WIFI_NOT_INIT: WiFi is not initialized by esp_wifi_init
-
esp_err_t esp_wifi_get_event_mask(uint32_t *mask)

Send raw ieee80211 data.
- Attention

- Parameters
ifx – interface if the Wi-Fi mode is Station, the ifx should be WIFI_IF_STA. If the Wi-Fi mode is SoftAP, the ifx should be WIFI_IF_AP. If the Wi-Fi mode is Station+SoftAP, the ifx should be WIFI_IF_STA or WIFI_IF_AP. If the ifx is wrong, the API returns ESP_ERR_WIFI_IF.
buffer – raw ieee80211 buffer
len – the length of raw buffer, the len must be <= 1500 Bytes and >= 24 Bytes
en_sys_seq – indicate whether use the internal sequence number. If en_sys_seq is false, the sequence in raw buffer is unchanged, otherwise it will be overwritten by WiFi driver with the system sequence number. Generally, if esp_wifi_80211_tx is called before the Wi-Fi connection has been set up, both en_sys_seq==true and en_sys_seq==false are fine. However, if the API is called after the Wi-Fi connection has been set up, en_sys_seq must be true, otherwise ESP_ERR_INVALID_ARG is returned.

Functions
-
esp_err_t esp_wifi_wps_enable(const esp_wps_config_t *config)
Enable Wi-Fi WPS function.
- Parameters
config – : WPS config to be used in connection
- Returns
ESP_OK : succeed
ESP_ERR_WIFI_WPS_TYPE : wps type is invalid
ESP_ERR_WIFI_WPS_MODE : wifi is not in station mode or sniffer mode is on
ESP_FAIL : wps initialization fails
-
esp_err_t esp_wifi_wps_disable(void)
