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.
