 <p>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!</p>

 <p>Cf is available from 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.</p>
