CoAP Protocol Implementation

Implement the Constrained Application Protocol (CoAP) on ESP32, a lightweight UDP-based protocol designed for constrained IoT devices and networks.

Develop simple web interfaces (HTML, CSS, JS) hosted on the ESP32’s web server for device monitoring, configuration, and control via a browser.

Learn principles of designing and implementing RESTful APIs directly on the ESP32, enabling interaction via standard HTTP methods.

Create an HTTP or secure HTTPS web server on the ESP32 to serve web pages, provide APIs, or enable local device configuration and control.

Implement RESTful API clients on ESP32 using HTTP/HTTPS. Interact with web services, send data, and retrieve information securely.

Explore advanced MQTT messaging patterns like request/response over MQTT, suitable for command-and-control scenarios with ESP32 devices.

Learn about MQTT bridges and proxies and how they can be used in ESP32 IoT deployments to connect different brokers or networks.

Understand and use MQTT retained messages on ESP32. Allow new subscribers to immediately receive the last known good value for a specific topic.

Utilize the MQTT Last Will and Testament (LWT) feature on ESP32 to notify other clients or systems if a device disconnects ungracefully.

Learn best practices for designing effective MQTT topic structures for your ESP32-based IoT applications. Organize data flow efficiently.
