Chapter 6: A Good Old Friend – Wi-Fi

Wi-Fi (of the IEEE 802.11 family of standards) is the most prominent wireless standard in the industry, so Espressif has integrated this technology into all of its products – ESP32 is no exception. In this chapter, we will learn how to use ESP32 in a Wi-Fi environment by connecting it to a local Wi-Fi network. After connecting to local Wi-Fi, a huge world of IoT opens that lets ESP32 communicate with servers and other connected devices. ESP-IDF provides all the software support needed to develop Transmission Control Protocol/Internet Protocol (TCP/IP) applications.

This chapter contains practical examples of client/server solutions over TCP/IP. We will discuss how to implement Hypertext Transfer Protocol ...
