IoT Application Development with the ESP32 Using the ESP-IDF

Develop a WiFi based application on the ESP32 and Subscribe/Publish MQTT Messages to AWS IoT using ESP-IDF & FreeRTOS

Created by: Kevin Aguilar
Embedded Software Engineer

What Will I Learn?

• How to develop WiFi based applications on the ESP32 using the ESP-IDF
• Integrate a Components & Sensors Library, allowing for easy integration of sensors and other components to your projects
• Configure ESP AWS IoT on the ESP32 to enable AWS IoT cloud connectivity
• Publish/subscribe AWS IoT Core MQTT messages and test using the MQTT test client
• Quickly and easily set up ESP-IDF (Espressif IoT Development Framework) projects using the Eclipse-based Espressif IDE
• Develop extensible, modular applications on the ESP32 using the ESP-IDF
• Develop an application with WiFi, HTTP server, Web Page, Non-Volatile Storage, OTA Firmware Updates, SNTP Time Synchronization, RGB LED, Button with Interrupt
• Utilize FreeRTOS for task management and intertask communication
• How to build, flash and monitor the application all within the IDF version of Eclipse
• How to develop a simple web page for displaying data, connecting the ESP32 to an access point, disconnect the ESP32, upload new firmware (OTA update) and more
• You will learn how to utilize FreeRTOS primitives, such as message queues, event groups, and semaphores
• Learn how to develop and extend a web page using .HTML, JavaScript and CSS and develop an HTTP server to support web page functionality
• By the end of the course, you will feel confident in developing an extensible WiFi based application using the ESP-IDF

Requirements

• ESP32 Development Kit
• DHT22 Sensor if you want to get temperature and humidity data
• RGB LED if you want to create LED status colors
• Jumper wires and a breadboard
• Familiarity with the C programming language

Target audience

• Anyone with some C language experience interested in developing applications on the ESP32
• Professionals interested in getting started with embedded software development on the ESP32
• Hobbyists looking to further their development skills by moving past programming the ESP32 using Arduino by using the ESP-IDF
