Java implementation of the CoAP protocol using netty

nCoAP

Java implementation of the CoAP protocol (RFC 7252)

See: https://datatracker.ietf.org/doc/rfc7252/

This implementation currently supports the main protocol according to RFC 7252 (without SSL) plus

• the core link format (see https://datatracker.ietf.org/doc/rfc6690/) and
• the observe extension (draft 14) (see http://tools.ietf.org/html/draft-ietf-core-observe-14).

Maven

The nCoAP project is organized in several maven modules, i.e.,

<groupId>de.uniluebeck.itm</groupId>
<artifactId>ncoap-core</artifactId>

for the raw protocol implementation. For CoAP application development this is probably what you want. To use the latest protocol implementation release add the following to your pom.xml

<repositories>
...
    <repository>
        <id>itm-maven-repository-releases</id>
        <name>ITM Maven Releases Repository</name>
        <url>https://maven.itm.uni-luebeck.de/content/repositories/releases</url>

        <artifactId>ncoap-core</artifactId>
        <version>1.8.2</version>
    </dependency>

The other models, i.e.,

<groupId>de.uniluebeck.itm</groupId>
<artifactId>ncoap-simple-client</artifactId>

and

<groupId>de.uniluebeck.itm</groupId>
<artifactId>ncoap-simple-server</artifactId>

provide simple CoAP applications for both, client and server. There intention is to highlight, how easy it is to write such applications using ncoap.
