#using https
git clone https://github.com/eclipse/leshan.git
Compile it, by running in leshan root folder :
mvn clean install
Run demo server:
java -jar leshan-server-demo/target/leshan-server-demo-*-SNAPSHOT-jar-with-dependencies.jar
Connect on Leshan demo UI: http://localhost:8080
Leshan server Demo provides a very simple UI to get the list of connected clients and interact with clients resources.
Now you can register a LWM2M client by running our client demo:
java -jar leshan-client-demo/target/leshan-client-demo-*-SNAPSHOT-jar-with-dependencies.jar
or trying the Eclipse Wakaama test client.
You can also try our bootstrap demo server:
java -jar leshan-bsserver-demo/target/leshan-bsserver-demo-*-SNAPSHOT-jar-with-dependencies.jar
Let's start to code !
Now you played a bit with our demo, you should start to code your own server or client using our Getting-started guide.
