FOTA in Embedded Systems: Update Firmware Wirelessly

Want to update your embedded devices without cables or physical access?

This course is a practical introduction to Firmware Over-The-Air (FOTA) — a critical feature in modern IoT and embedded systems. You'll learn how to remotely update firmware on microcontrollers like ESP32, STM32, or similar platforms using real-world tools and communication protocols.

The course covers both theory and hands-on implementation, teaching you how FOTA works internally and how to build a complete update system that is reliable and secure.

You’ll learn:

• What is FOTA and why it’s important

• Flash memory management for updates

• Downloading firmware via HTTP, HTTPS, or MQTT

• Validating firmware (checksum, signature)

• Switching between firmware partitions (bootloader techniques)

• Rollback and fail-safe mechanisms

You’ll build a working FOTA system from scratch using real hardware (like ESP32 or STM32), open-source tools, and basic networking knowledge.

By the end of this course, you'll be confident in designing embedded products that can receive secure updates over the air — a must-have skill for any serious embedded developer.
