Build secure ESP32 IoT firmware with ESP-IDF, FreeRTOS, Wi-Fi provisioning, MQTT, HTTP, AES and HMAC in C.
What you'll learn
Build a modular ESP32 firmware project in C using ESP-IDF components, CMake, and a clean project structure. Design a FreeRTOS-based IoT firmware architecture with tasks, queues, mutexes, and event-driven callbacks. Implement Wi-Fi station mode, AP provisioning, browser-based credential setup, and NVS credential storage. Receive and validate MQTT sensor messages using JSON parsing, HMAC-SHA256 integrity checks, and range validation. Expose telemetry through an ESP32 HTTP server with Basic Authentication and encrypted JSON responses. Create a secure MQTT-to-HTTP telemetry pipeline using AES-256-CBC, HMAC signatures, and FreeRTOS queues.Requirements
An ESP32 development board and a Micro-USB or USB cable for flashing and testing the firmware. A Windows, macOS, or Linux computer with ESP-IDF installed; installation is covered in the course. Basic C programming knowledge and familiarity with microcontrollers or embedded systems will help. No prior ESP-IDF, FreeRTOS, MQTT, or HTTP server experience is required; the course builds these step by step.Description
This course contains the use of artificial intelligence.
This course takes you beyond simple ESP32 examples and walks you through the development of a production-style secure sensor firmware architecture. You will start by setting up ESP-IDF, understanding the project structure, creating components, building firmware, flashing the ESP32, and reviewing how memory and partitions work inside the device.
From there, you will design and implement a modular firmware system controlled by a top-level state machine. You will build Wi-Fi station mode, access point provisioning, browser-based credential setup, and persistent storage using NVS. You will also learn how FreeRTOS concepts such as tasks, queues, mutexes, and event-driven callbacks are used to create reliable embedded applications.
The course then moves into networking and security. You will implement an HTTP server on the ESP32, add Basic Authentication, create a telemetry queue, build secure HTTP responses, and use AES encryption and HMAC-SHA256 signatures to protect sensor data. Finally, you will implement MQTT communication, parse JSON sensor messages, validate incoming telemetry, and connect the full MQTT-to-HTTP data pipeline.
By the end of the course, you will have built a complete ESP32 IoT gateway-style firmware project in C using ESP-IDF and FreeRTOS.
This course is ideal for embedded systems learners, IoT developers, firmware engineers, students, and ESP32 users who want to gain practical experience with modular firmware architecture, networking, FreeRTOS, secure data handling, and real-world IoT system design.
Who this course is for
Embedded systems learners, IoT developers, and ESP32 users who want to build production-style firmware with ESP-IDF, FreeRTOS, MQTT, HTTP, and security.Homepage
