Explore the IoTivity-Constrained project, a small-footprint implementation of Open Connectivity Foundation's IoT standards designed for resource-constrained environments, in this 51-minute conference talk by Kishen Maloor from Intel Corporation. Delve into the architecture, features, APIs, and integration with popular real-time operating systems, including a detailed discussion on its adaptation for the Zephyr RTOS. Learn about the OCF resource model, protocols, device classes, and architectural goals of IoTivity-Constrained. Discover how to structure applications, define resources, handle requests and responses, and configure the framework for tiny IoT devices. Gain insights into IPv6 over BLE support and future plans for this lightweight, maintainable, and customizable solution for connecting the Internet of Things through resource-constrained edge devices.
