You can try live our servers demos instances:
- The lwm2m server at https://leshan.eclipseprojects.io/
(coap://leshan.eclipseprojects.io:5683 and coaps://leshan.eclipseprojects.io:5684) - The bootstrap server at https://leshan.eclipseprojects.io/bs/
(coap://leshan.eclipseprojects.io:5783 and coaps://leshan.eclipseprojects.io:5784)
(Automatic deployment of master branch)
Get and run the last binary of our demo server :
wget https://hudson.eclipse.org/leshan/job/leshan/lastSuccessfulBuild/artifact/leshan-server-demo.jar
java -jar ./leshan-server-demo.jar
Get and run the last binary of our demo client :
wget https://hudson.eclipse.org/leshan/job/leshan/lastSuccessfulBuild/artifact/leshan-client-demo.jar
java -jar ./leshan-client-demo.jar
Get and run the last binary of our bootstrap demo server :
wget https://hudson.eclipse.org/leshan/job/leshan/lastSuccessfulBuild/artifact/leshan-bsserver-demo.jar
java -jar ./leshan-bsserver-demo.jar
ℹ️ : All the demos have a --help option.
Get sources :
#using ssh
git clone git@github.com:eclipse/leshan.gitor
#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
Now you played a bit with our demo, you should start to code your own server or client using our Getting-started guide.
