In this lecture we’ll explore how to include libraries inside ESP-IDF, external libraries, and components from the ESP Component Registry

In this lesson, we introduce the layered structure of Internet communication, explaining the ISO/OSI model and the data encapsulation process. We also explore HTTP and MQTT protocols, showing how REST APIs and the JSON format enable communication between IoT devices and applications.

In this lesson, we are preparing the ground for the first practical exercise. We introduce ESP-IDF, the official Espressif framework for IoT application development, then explore its architecture, main components, and development tools. We also examine the hardware used in the workshop, based on the ESP32-C3 SoC.

Create a led-toggle component and refactor the hello_led example using the component

Add a new route to the HTTP server for a programmable blink (Optional)

Add more routes to the HTTP server to drive the LED remotely

Start a soft-AP and an HTTP server (guided)

Create a new project from the blink example and change the output GPIO pin via menuconfig
