Public Members
uint8_t ssid[32]
SSID of target AP.
uint8_t password[64]
Password of target AP.
wifi_scan_method_t
do all channel scan or fast scan
bool bssid_set
whether set MAC address of target AP or not. Generally, station_config.bssid_set needs to be 0; and it
needs to be 1 only when users need to check the MAC address of the AP.
uint8_t bssid[6]
MAC address of target AP
uint8_t channel
channel of target AP. Set to 1~13 to scan starting from the specified channel before connecting to AP. If
the channel of AP is unknown, set it to 0.
uint16_t listen_interval
Listen interval for ESP32 station to receive beacon when WIFI_PS_MAX_MODEM is set. Units: AP
beacon intervals. Defaults to 3 if set to 0.
wifi_sort_method_t sort_method
sort the connect AP in the list by rssi or security mode
wifi_scan_threshold_t
When sort_method is set, only APs which have an auth mode that is more secure than the selected auth
mode and a signal stronger than the minimum RSSI will be used.
wifi_pmf_config_t pmf_cfg
Configuration for Protected Management Frame. Will be advertized in RSN Capabilities in RSN IE.
uint32_t rm_enabled : 1
Whether Radio Measurements are enabled for the connection
uint32_t btm_enabled : 1
Whether BSS Transition Management is enabled for the connection
uint32_t mbo_enabled : 1
Whether MBO is enabled for the connection
uint32_t reserved : 29
Reserved for future feature set
struct wifi_sta_info_t
Description of STA associated with AP.
Public Members
uint8_t mac[6]

uint32_t phy_11b : 1
bit: 0 flag to identify if 11b mode is enabled or not
uint32_t phy_11g : 1
