Abstract

The rapid development of Internet of Things (IoT) technology has driven the need for efficient, secure, and reliable firmware update systems. Firmware plays a vital role in maintaining the performance, security, and functionality of IoT devices, including those based on the ESP32, which is widely used due to its cost-effectiveness and connectivity capabilities. However, conventional firmware update methods that require physical connections are inefficient for managing large-scale, distributed devices. Over-the-Air (OTA) technology offers a more relevant solution by enabling wireless firmware updates without manual intervention. This study aims to design and implement a cloud-based OTA firmware update system for ESP32 devices. In this approach, the ESP32 acts as a client that automatically downloads the latest firmware from a cloud server, eliminating the need for a local server infrastructure. The expected outcome is a system capable of efficiently distributing firmware, ensuring the integrity and authenticity of update files, and supporting large-scale IoT device management in a more practical and sustainable manner.
