In this blog, I will show you how to set a static IP address on Xiao ESP32 S3 Sense, a tiny but powerful microcontroller board with Wi-Fi and Bluetooth capabilities. Setting a static IP address can be useful if you want to access your ESP32 web server or other network services using the same IP address, even after restarting the board. false en Attribution (CC BY) Static_IP_Address_on_Xiao_ESP32_S3_Sense_1.JPG none An IP address is a unique identifier for a device on a network. It consists of four numbers separated by dots, such as 192.168.1.100. A static IP address is an IP address that does not change, unlike a dynamic IP address that is assigned by a router or a DHCP server. === Advantages === * Easier to remember and access. * More reliable and stable connection * Less prone to IP conflicts or errors === Disadvantages === * More difficult to configure and maintain. * Less flexible and scalable * More vulnerable to security risks Therefore, you should only use a static IP address if you have a specific need for it, and if you are aware of the potential drawbacks.

Before uploading, make sure to replace the ssid and password variables with your actual Wi-Fi network credentials. <div class="mw-highlight mw-content-ltr" dir="ltr"><pre>#include <WiFi.h> const char* ssid = "YourNetworkName"; const char* password = "YourPassword"; void setup() { Serial.begin(115200); Serial.print("Connecting to "); Serial.println(ssid); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(1000); Serial.print("."); } Serial.println(""); Serial.println("Connected..!"); Serial.print("Current ESP32 IP: "); Serial.println(WiFi.localIP()); Serial.print("Gateway (router) IP: "); Serial.println(WiFi.gatewayIP()); Serial.print("Subnet Mask: " ); Serial.println(WiFi.subnetMask()); Serial.print("Primary DNS: "); Serial.println(WiFi.dnsIP(0)); Serial.print("Secondary DNS: "); Serial.println(WiFi.dnsIP(1)); } void loop() { } </pre></div></nowiki> <nowiki>Open the Serial Monitor and set the baud rate to 115200. Then, press the EN button on the ESP32 board. It may take a few moments to connect to your network, after which it will print the current network settings of the ESP32 board to the serial monitor. Take note of these settings, especially the IP address, gateway, subnet mask, and DNS servers. * Choose a static IP address for your ESP32 board that is within the same subnet as your router but does not conflict with any other devices on your network. For example, if your router’s IP address is 192.168.1.1 and your subnet mask is 255.255.255.0, you can choose any IP address from 192.168.1.2 to 192.168.1.254, as long as it is not already taken by another device. You can check the IP addresses of other devices on your network using tools such as [https://randomnerdtutorials.com/esp32-static-fixed-ip-address-arduino-ide/ Fing] or [https://lastminuteengineers.com/esp32-static-ip-tutorial/ Advanced IP Scanner.] * Modify the previous sketch by adding the following lines before the WiFi.begin() function. Replace the staticIP, gateway, subnet, primaryDNS, and secondaryDNS variables with your chosen static IP address and the network settings you obtained in step 4. <div class="mw-highlight mw-content-ltr" dir="ltr"><pre>// Static IP configuration IPAddress staticIP(192, 168, 1, 100); // ESP32 static IP IPAddress gateway(192, 168, 1, 1); // IP Address of your network gateway (router) IPAddress subnet(255, 255, 255, 0); // Subnet mask IPAddress primaryDNS(192, 168, 1, 1); // Primary DNS (optional) IPAddress secondaryDNS(0, 0, 0, 0); // Secondary DNS (optional) // Configures static IP address if (!WiFi.config(staticIP, gateway, subnet, primaryDNS, secondaryDNS)) { Serial.println("STA Failed to configure"); } </pre></div> * Upload the modified sketch to your ESP32 board and open the Serial Monitor again. You should see that your ESP32 board has successfully connected to your network using the static IP address you specified. * You can now access your ESP32 web server or other network services using the static IP address. For example, if you have uploaded the [https://bing.com/search?q=how+to+set+static+IP+address+on+Xiao+ESP32+S3+Sense ESP32 Web Server] example sketch, you can open a web browser and type the static IP address in the address bar. You should see the web page that allows you to control the GPIO pins of your ESP32 board. </nowiki> <nowiki>Apart from controlling the LED's we can implement this on ESP32 Cam Webserver.
