IoTivity is an open source software project enabling seamless device-to-device connectivity where billions of wired and wireless Internet of Things (IoT) devices can securely connect to each other and to the internet. The Open Connectivity Foundation (OCF) develops specifications, interoperability guidelines, and a certification program for these devices. IoTivity is an open source reference implementation of the OCF specification. You can learn more about OCF at http://openconnectivity.org and IoTivity at http://iotivity.org.
The IoTivity framework APIs expose the framework to developers, and are available in several programming languages and for multiple operating systems. The framework supports dedicated and optimized protocols for IoT, with specific considerations for constrained devices and addressing all types of devices, form-factors, companies, ecosystems and markets.
The IoTivity framework operates as middleware across all operating systems and connectivity platforms and has these four essential building blocks:
- Discovery: supporting multiple mechanisms for discovering devices and resources in proximity and remotely.
- Data transmission: supporting information exchange and control based on a messaging and streaming model.
- Data management: supporting the collection, storage and analysis of data from various resources.
- Device management: supporting configuration, provisioning and diagnostics of devices.
The OCF Developer Kit shows how to set up an IoTivity development environment on a Raspberry Pi 3 board. This kit provides you with a Raspberry Pi 3 board and additional hardware to get you started with IoT development using IoTivity APIs and interacting with sensor devices. You’ll be building and running the sample client and server applications on the Raspberry Pi 3 board itself. You’ll have verified the on-board development environment and tools are set up and working. You can go through the sample application source code to see how it works and even make changes on your own to learn and explore more!
Materials Needed to build your own Developer Kit:
