Microcontroller Programming Series - Mastering ESP32 Wi-Fi features

Mastering ESP32 Wi-Fi Features is a practical, beginner-friendly guide designed to help you understand and confidently use Wi-Fi capabilities in the ESP32. Instead of only showing how to connect to a network, this book explains how Wi-Fi actually works inside the ESP32 and how to control it for real-world IoT applications.

You will start with the basics of Wi-Fi technology and gradually move into advanced topics such as different Wi-Fi modes, network scanning, power management, signal quality, frequency and channel control, data communication, and security. Each concept is explained in simple language, with a clear focus on practical use so learners can apply the knowledge immediately in projects.

This book is ideal for students, beginners, hobbyists, and professionals who want a complete and structured understanding of ESP32 Wi-Fi. Whether you are building smart home systems, industrial IoT devices, or learning embedded networking for the first time, this book will guide you step by step from fundamentals to advanced techniques.

Inside this book, you will learn:

• How Wi-Fi works in the ESP32 at hardware and software levels
• Different ESP32 Wi-Fi modes and when to use each one
• Reliable Wi-Fi connection handling and troubleshooting
• Power-saving techniques for battery-powered IoT devices
• Monitoring signal strength, quality, and interference
• Managing Wi-Fi channels, frequency, and bandwidth
• Using TCP, UDP, HTTP, DHCP, DNS, and mDNS with ESP32
• Implementing secure Wi-Fi using WPA, WPA2, and PSK methods

By the end of this book, you will have the confidence and practical knowledge needed to design stable, efficient, and secure Wi-Fi-enabled ESP32 projects.
