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.

In this chapter, we have learned about a number of popular display technologies and how to use them in our ESP32 projects when an immediate output to end users is required. It is important to know the differences between those technologies to select the right display type in a project. FreeRTOS was an important subject of this chapter as well. It is the official real-time operating system of ESP32, supported by Espressif. We have discussed the differences between the vanilla FreeRTOS and the ESP-IDF versions with the help of examples.

We will talk about the advanced features of ESP32 in the next chapter, including multimedia peripherals and power management subsystems. When a battery-operated device is to be designed, the ULP co-processor of ESP32 can be very handy for achieving low power consumption. All these subjects will be covered next.
