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

There are many ways to connect to cloud platforms. No cloud platform can provide endpoints for all available IoT protocols but some of those protocols are quite common and well-supported by cloud vendors. They are MQTT, CoAP, and WebSocket, which we have discussed with examples in this chapter. We can choose any of them according to the technical requirements of a given project. We also had a brief overview of some major cloud providers. We examined their features and offerings to understand what to expect from an IoT platform. To exemplify cloud integration, we developed a simple application that connects and communicates with the AWS IoT platform over the MQTT protocol. Although this chapter barely scratches the surface of what we can do with an IoT platform, it explains the fundamentals of cloud communication techniques that we can apply in any IoT project with any IoT platform vendor.

In the next chapter, we will talk about other cloud services that we can integrate...
