esp_wifi_init failed by invalid magic number

[AndiRo]

I am trying to initialize wifi in an function and call it in the main.c

I am using esp-idf v4.4.3 and esp-adf v2.4.1
I wont use the wifi for an audio stream its just for an webserver to change some settings

you can see the initialization code here
its the same like the wifi get started example

Code: Select all

    esp_err_t ret;
    
    ret = nvs_flash_init();
    if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND) {
      ESP_ERROR_CHECK(nvs_flash_erase());
      ret = nvs_flash_init();
    }
    ESP_ERROR_CHECK(ret);


    ESP_ERROR_CHECK(esp_netif_init());
    ESP_ERROR_CHECK(esp_event_loop_create_default());
    esp_netif_create_default_wifi_ap();


    const wifi_init_config_t cfg_123 = WIFI_INIT_CONFIG_DEFAULT();
    ESP_LOGI(LOGTAG, "debug: %d ", cfg_123.magic );
    ESP_ERROR_CHECK(esp_wifi_init(&cfg_123));


    ESP_ERROR_CHECK(esp_event_handler_instance_register(WIFI_EVENT,
                                                        ESP_EVENT_ANY_ID,
                                                        &wifi_event_handler,
                                                        NULL,
                                                        NULL));
                                                        
    wifi_config_t wifi_config = {
        .ap = {
            .ssid = EXAMPLE_ESP_WIFI_SSID,
            .ssid_len = strlen(EXAMPLE_ESP_WIFI_SSID),
            .channel = EXAMPLE_ESP_WIFI_CHANNEL,
            .password = EXAMPLE_ESP_WIFI_PASS,
            .max_connection = EXAMPLE_MAX_STA_CONN,
            .authmode = WIFI_AUTH_WPA_WPA2_PSK
        },
    };
    if (strlen(EXAMPLE_ESP_WIFI_PASS) == 0) {
        wifi_config.ap.authmode = WIFI_AUTH_OPEN;
    }

    ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_AP));
    ESP_ERROR_CHECK(esp_wifi_set_config(WIFI_IF_AP, &wifi_config));
    ESP_ERROR_CHECK(esp_wifi_start());

if I place the initialization in my main everything works fine

But if I put it in an function and call it in my main esp_wifi_init aborts caused by invalid (magic number) argument

a already tried to do
git submodule update --init --recursive

Thanks in advance for your help
