/ESP32-WiFi-Connection-Example

This repository contains a simple example demonstrating how to connect an ESP32 microcontroller to a Wi-Fi network using the Arduino IDE. The code connects to a Wi-Fi network, monitors the connection progress, and retrieves the ESP32's IP address along with the router's gateway IP.

ESP32 Wi-Fi Connection Example

Welcome to the ESP32 Wi-Fi Connection Example repository! This project showcases how to connect an ESP32 microcontroller to a Wi-Fi network and retrieve basic network information using the Arduino IDE. It is designed for users who want to get started with Wi-Fi connectivity on the ESP32.

📦 Features

  • Wi-Fi Connection: Easily connect your ESP32 to any Wi-Fi network using your SSID and password.
  • Connection Status: Monitor the status of the connection attempt through the Serial Monitor.
  • Network Information: Retrieve and display the ESP32’s IP address and the router's gateway IP address.

🚀 Getting Started

To use this example, follow these steps:

1. Clone the Repository

Clone this repository to your local machine using:

git clone https://github.com/yourusername/ESP32-WiFi-Connection-Example.git

2. Install the Arduino IDE

Ensure you have the Arduino IDE installed. You will also need to install the ESP32 board support package.

3. Upload the Code

  1. Open the main.ino file in the Arduino IDE.
  2. Replace Your_SSID and Your_PASSWORD with your Wi-Fi network credentials.
  3. Connect your ESP32 board to your computer using a USB cable.
  4. Select the correct board and port in the Arduino IDE.
  5. Click on the upload button to compile and upload the code to your ESP32.

4. View Results

Open the Serial Monitor (set the baud rate to 115200) to view the connection progress and network information.

📋 Code Explanation

Here’s a detailed breakdown of the code:

#include <WiFi.h>
  • #include <WiFi.h>: This line includes the Wi-Fi library required to handle Wi-Fi functions for the ESP32.
const char* ssid = "Your_SSID";
const char* password = "Your_PASSWORD";
  • const char* ssid: Replace "Your_SSID" with the name of your Wi-Fi network.
  • const char* password: Replace "Your_PASSWORD" with your Wi-Fi network password.
void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  • void setup(): This function runs once when the ESP32 is powered on or reset.
  • Serial.begin(115200): Initializes serial communication at a baud rate of 115200 to print messages to the Serial Monitor.
  • WiFi.begin(ssid, password): Starts the process of connecting to the Wi-Fi network using the provided SSID and password.
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  • while (WiFi.status() != WL_CONNECTED): Continuously checks if the ESP32 is connected to the Wi-Fi network. If not, it waits for 500 milliseconds and prints a dot to indicate progress.
  Serial.println("Connected to Wi-Fi");
  Serial.print("IP Address: ");
  Serial.println(WiFi.localIP());
  Serial.print("Gateway (Router IP): ");
  Serial.println(WiFi.gatewayIP());
}
  • Serial.println("Connected to Wi-Fi"): Prints a message indicating that the ESP32 has successfully connected to the Wi-Fi network.
  • Serial.print("IP Address: "): Prints the IP address assigned to the ESP32 by the router.
  • Serial.println(WiFi.localIP()): Prints the actual IP address of the ESP32.
  • Serial.print("Gateway (Router IP): "): Prints the IP address of the router (gateway) to which the ESP32 is connected.
  • Serial.println(WiFi.gatewayIP()): Prints the actual IP address of the gateway (router).
void loop() {
  // Empty loop
}
  • void loop(): This function runs repeatedly after the setup() function. In this example, it is left empty because no further actions are needed.
