Re: [iot-wg] Kona Project

Yes, this is how I understand it. Kona is a Java library for CoAP with LWM2M client support, contributed by ARM, meant to be used more or less as the HTTP client API is used in a web app.

It is useful as a LWM2M client endpoint on richer devices that can run Java, and we also use it as the north facing interface of the BT Smart to LWM2M gateway.

Best regards,

Michael

Kona is based on the CoAP implementation by Sensinode. I would compare it roughly to the HTTP API you have in Java and the Apache HTTP libraries. Californium also focuses on backend services. We put a lot of effort into the performance and are three times faster than other CoAP implementations. Another aspect in Californium is providing a nice framework for REST applications.
 
In the longrun, it might be good to define a good strategy how to place Californium. Some time ago, I was talking to the Vert.x guys. They have a really nice polyglot application framework there and they were still looking for a CoAP implementation…
 
My two cents

Matthias might have some comments too but I think the license will be different. Kona would be licensed under GPL with classpath exception since it is a OpenJDK project.

All,
 
Have you already heard of the Kona project?
 
With primary focus on CoAP (for the start), I wonder how Californium could be positioned here? Any thoughts?
 
Best regards,
Kai
