Summary
One reason why ESP32 is so popular is its superior connectivity features. Wi-Fi, as the most common wireless protocol in the world, is integrated in ESP32 to help developers create outstanding products. In this chapter, we have learned a lot about how we can utilize ESP32's Wi-Fi functionality in our projects. On top of Wi-Fi, ESP32 supports almost any kind of TCP/IP application with its advanced framework, ESP-IDF. The lwIP stack is adopted in the framework. It enables us to connect to servers on the internet and communicate with other connected devices, which is at the heart of IoT.
The next chapter is devoted to the security features of ESP32. It would be a serious mistake to launch an IoT product on the market without well-planned, well-designed, and well-tested security. ESP32 provides all the hardware support necessary for this. We will discuss how to leverage ESP32 to develop secure IoT applications in the next chapter.
