ESP32 IoT Development Applications - From Wi-Fi to Bluetooth BLE

This course is designed for learners who have mastered the basic development methods of the ESP32 to progressively study low-power design → Wi-Fi networks → REST APIs → Web Servers → MQTT → OTA → Bluetooth BLE, with the goal of directly implementing the communication functions required for real-world IoT devices. The main goals of this course are as follows: - Understand and utilize low-power features of the ESP32, such as Light Sleep and Deep Sleep - Configure Wi-Fi Station/AP modes and handle network connections and exceptions - Implement communication with external servers using HTTP/HTTPS and REST APIs - Configure a Web Server and WebSocket server within the ESP32 - Host websites and React-based UIs directly on the ESP32 - Implement MQTT-based Publish/Subscribe communication - Perform remote firmware updates and version management using OTA - Understand the GAP/GATT structure of Bluetooth BLE based on NimBLE and implement Server/Client functionality
