Consultar el motivo del fallo de la conexión wifi en esp-idf

Agregue el siguiente código a la parte donde falló la conexión Wi-Fi:

ESP_LOGI(TAG,"reason: fail %d\n", event->event_info.disconnected.reason);

P.ej:

    case SYSTEM_EVENT_STA_DISCONNECTED:
        {
    
    
            if (s_retry_num < EXAMPLE_ESP_MAXIMUM_RETRY) {
    
    
                esp_wifi_connect();
                xEventGroupClearBits(s_wifi_event_group, WIFI_CONNECTED_BIT);
                s_retry_num++;
                ESP_LOGI(TAG,"retry to connect to the AP");
            }
            ESP_LOGI(TAG,"connect to the AP fail\n");
            ESP_LOGI(TAG,"reason: fail %d\n", event->event_info.disconnected.reason);
            break;
        }

Luego compile, grabe y abra el monitor serial. Si Wi-Fi verificará el motivo de error correspondiente en el terminal en este momento, por ejemplo:

I (10654) wifi station: connect to the AP fail

I (10654) wifi station: reason: fail 201

NOTA: Si los problemas del canal, la falla de la conexión Wi-Fi ocurre en 13 & caso SSID oculto, algo como las siguientes modificaciones policy:
wifi_country_t wifi_country = {0};
ESP_ERROR_CHECK (esp_wifi_get_country (& wifi_country));
wifi_country.policy = WIFI_COUNTRY_POLICY_MANUAL;
ESPERROR_ (esp_wifi_set_country (& wifi_country));
