Exploring HTTP with ESP32 – enabling IoT devices to communicate with web servers

In the interconnected world of IoT, efficient communication between devices and web servers is paramount. One of the foundational protocols that has powered the internet since its beginning is HTTP. In the context of IoT, HTTP plays a pivotal role in facilitating communication between resource-constrained devices, such as the ESP32 microcontroller, and remote web servers. This section dives into the details of HTTP communication, specifically tailored for ESP32 projects. We’ll explore how ESP32 can seamlessly interact with web servers, enabling IoT devices to exchange data, retrieve information, and contribute to the ever-expanding landscape of IoT. First, let’s explore what the HTTP protocol is and how it works.

What is HTTP?

HTTP is the foundation of data communication on the World Wide Web. It is an application layer protocol that defines how clients (typically web browsers...
