[Z-SHOCK-E]

Esp32 wifi wps(push button) can be used to authenticate with a router and save the password as a test file.

Today I dig into provided examples and tried to adapt it for Bruce... And found some caveat.

The Bruce firmware uses really outdated ESP-IDF version (4.4.7). So it lacks of full WPS functionality.

There is esp_wps_config_t structure that passed into esp_wifi_wps_enable function.

The main problem In 4.4.7 it just haven't field for the PIN code:

typedef struct {
    wps_type_t wps_type;
    wps_factory_information_t factory_info;
} esp_wps_config_t;

If we check docs for the 5.0+ version we will find that it suddenly appears:

typedef struct {
    wps_type_t wps_type;
    wps_factory_information_t factory_info;
    char pin[PIN_LEN]
} esp_wps_config_t;
