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.

Summary

This chapter explained an important feature of ESP32, BLE. BLE has many advantages over other wireless protocols. Probably the key advantage is the compatibility with mobile devices. Every mobile device manufacturer supports BLE in their designs, which eliminates the need for a separate gateway device to communicate with the sensor network. Therefore, it is super easy to develop impressive IoT products with powerful GUI applications for end users. Although BLE is a massive subject, we had a good start in this chapter by covering beacons, a standalone GATT server device, and setting up a BLE Mesh network for multiple IoT devices, which are extremely useful when local connectivity is needed.

In the next chapter, we will develop a full-fledged smart home by employing ESP32's networking capabilities.
