Californium (Cf) core
The project is divided into five sub-projects. The Californium (Cf) core provides the central framework with the protocol implementation to build your Internet of Things applications. This repository also includes example projects to get you started. All Californium sources are hosted on GitHub, so you can easily contribute through pull requests.
Californium (Cf) is dual-licensed under EPL and EDL. The latter is a BSD-like license, which means the Cf CoAP framework can be used together with proprietary code to implement your IoT product!
Cf is available in Maven Central and very easy to consume in your Java project. We have got your back covered from OSGi wrapper to HTTP-CoAP cross-proxy to advanced test suites that have been used at the ETSI Plugtests.

Connector
The element-connector abstracts from the different transports CoAP can use. It provides the basic UDPConnector as well as the interface to implement new connectors like the DtlsConnector of Scandium.
Repository »Getting started. Take the tutorial.
The Internet of Things if growing, but how can you build your own connected objects? Together with MQTT, CoAP is one of the popular IoT protocols. It provides answers to the typical IoT constraints: it is bandwidth efficient and fits in constrained embedded environment while providing friendly and discoverable RESTful API.
