本课程深入ESP32物联网固件开发，涵盖ESP-IDF、FreeRTOS、Wi-Fi配网及AES加密，助你构建工业级安全嵌入式系统，应对网络安全挑战。
原始标题：Master ESP32-based IoT System Firmware Development
该课程是一门面向具备基础 C 语言与微控制器操作经验开发者的物联网硬核实战课，核心聚焦于基于 ESP-IDF 官方框架与 FreeRTOS 实时操作系统，构建具备工业级安全性的 ESP32 模块化嵌入式固件体系。课程直面物联网设备易受网络攻击、凭证泄露及内存溢出等安全痛点，放弃了表面化的 Demo 演示，而是深入底层架构：从搭建清晰的 CMake 多组件工程目录与分区表开始，教你如何利用 FreeRTOS 任务、安全队列与互斥锁设计高并发、防死锁的流量管道；在网络与存储层面，课程涵盖了通过 SoftAP 网页端进行 Wi-Fi 配网以及配合 eFuse 硬件加密的 NVS 本地凭证安全存储。
核心亮点在于全链路的安全加密实战——你将调用 mbedTLS 硬件加速引擎实现 AES-256-CBC 数据加密与 HMAC-SHA256 完整性校验，以防止传输监听和篡改；同时通过 cJSON 进行严格的边界与范围防爆验证，并最终搭建起集成了 HTTPS 基础认证（Basic Auth）本地服务器与双向认证（mTLS）MQTTS 远程网关的端到端安全数据传输闭环。

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.
