Scandium and Kura [message #1689002]

Hi guys,

I was trying to add DTLS to a CoAP server (powered by Californium) using Scandium.

I followed an example in the Californium project called SecureServer.java.

Finally I get it working on the Kura emulator but I have problems with the RasPi.
I guess because there is no handshake between client and server.
I've opened 5684 port on the UI web server.

On the tail -F .../kura.log I can't see the internal logger of Scandium.

Even with try{ ... }catch(Throwable e){logger.error(e.getMessage(), e)}; it shows nothing.

How can I do to solve this problem? Or at least how can I receive notification from the internal logger of Scandium on the RasPi?

Ciao Gianvito,
the System output and error streams are redirected to /var/log/kura-console.log
If Scandium uses normal System.out you should see logging there.

How did you include Scandium and Californium in the build? Do you simply use them as libraries inside the project?

If you are able to provide the source code, I could have a look at it.

Ciao Luca,

Ok thank you. I'll try using that log.

Yes. I'm trying to create different Services to have a distributed (tree based) CoAP support using MQTT.
In one of these bundles (the base one) there are californium and scandiun libs (exported in the MANIFEST), so other Services can use them.

I'm working at it and I'm trying to develop a UI configurable support.

I had this problem and if I could see the whole log (Scandium included) it would be easier for me to find the problem.

Thank you,
Gianvito
