Developing IoT Projects with ESP32

By: Vedat Ozan Oner

Overview of this book

Developing IoT Projects with ESP32 provides end-to-end coverage of secure data communication techniques from sensors to cloud platforms that will help you to develop production-grade IoT solutions by using the ESP32 SoC. You'll learn how to employ ESP32 in your IoT projects by interfacing with different sensors and actuators using different types of serial protocols. This book will show you how some projects require immediate output for end-users, and cover different display technologies as well as examples of driving different types of displays. The book features a dedicated chapter on cybersecurity packed with hands-on examples. As you progress, you'll get to grips with BLE technologies and BLE mesh networking and work on a complete smart home project where all nodes communicate over a BLE mesh. Later chapters will show you how IoT requires cloud connectivity most of the time and remote access to smart devices. You'll also see how cloud platforms and third-party integrations enable endless possibilities for your end-users, such as insights with big data analytics and predictive maintenance to minimize costs. By the end of this book, you'll have developed the skills you need to start using ESP32 in your next wireless IoT project and meet the project's requirements by building effective, efficient, and secure solutions.

Chapter 7: Security First!

Any internet-facing solution must be designed with security-first in mind, otherwise it is vulnerable to cyber-attacks. This especially applies to IoT products since they are usually introduced in batches to the market and delivered to end users who often don't have any basic understanding of IoT security.

When it comes to security, ESP32 provides a good level of hardware support for developers with its cryptography subsystem. ESP-IDF also integrates industry-standard encryption libraries and provides a good abstraction when a custom security solution is needed. In this chapter, we will discuss the essentials of the ESP32 platform when developing production-grade IoT devices and see examples of secure communication protocols to understand how to utilize them in our projects. This chapter requires some background knowledge to follow the examples easily. If you don't feel comfortable with the security fundamentals, you can find some resources...
