Wifi-connect 4 - Additional code that manually sets IP in github, not in video

[swimleftproducts]

The git hub for Wifi-connect 4 has some additional code in it, particularly lines 165- 170 of the wifi component connect.c file.

esp_netif_dhcpc_stop(esp_netif);
esp_netif_ip_info_t ip_info;
ip_info.ip.addr = ipaddr_addr("192.168.0.222");
ip_info.gw.addr = ipaddr_addr("192.168.0.1");
ip_info.netmask.addr = ipaddr_addr("255.255.255.0");
esp_netif_set_ip_info(esp_netif, &ip_info);

I do not think this code was covered in this section. Can you point me to where this code is covered? Thanks!

@swimleftproducts Good catch.

I have commented those lines out now but I left them in as this is how you can force the ESP32 to use a static IP.
new code as follows

esp_err_t wifi_connect_sta(const char *ssid, const char *pass, int timeout)
{
    Wifi_events = xEventGroupCreate();
    wifi_config_t wifi_config;
    memset(&wifi_config, 0, sizeof(wifi_config_t));
    strncpy((char *)wifi_config.sta.ssid, ssid, sizeof(wifi_config.sta.ssid) - 1);
    strncpy((char *)wifi_config.sta.password, pass, sizeof(wifi_config.sta.password) - 1);

    esp_netif = esp_netif_create_default_wifi_sta();

    // for static ip...
    // esp_netif_dhcpc_stop(esp_netif);
    // esp_netif_ip_info_t ip_info;
    // ip_info.ip.addr = ipaddr_addr("192.168.0.222");
    // ip_info.gw.addr = ipaddr_addr("192.168.0.1");
    // ip_info.netmask.addr = ipaddr_addr("255.255.255.0");
    // esp_netif_set_ip_info(esp_netif, &ip_info);

    ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_STA));
    ESP_ERROR_CHECK(esp_wifi_set_config(ESP_IF_WIFI_STA, &wifi_config));
    ESP_ERROR_CHECK(esp_wifi_start());

    EventBits_t result = xEventGroupWaitBits(Wifi_events, CONNECTED_GOT_IP | DISCONNECTED, pdTRUE, pdFALSE, pdMS_TO_TICKS(timeout));
    if (result == CONNECTED_GOT_IP)
        return 0;
    return -1;
}
