3.0.0-RC1 DTLS configuration from file

[Strauteka]

How can I add DTLS.* configuration from *.properties file?
Currently I can set DTLS config from code, but not load from file.

this.configuration.set(DtlsConfig.DTLS_CONNECTION_ID_LENGTH, 5);
this.configuration.get(DtlsConfig.DTLS_CONNECTION_ID_LENGTH);

Using org.eclipse.californium.elements.configConfiguration.createFromStream(coapEndpointFile.getInputStream(), EndpointConfiguration.DEFAULTS);

Printing
[main] WARN o.e.c.elements.config.Configuration - Ignore DTLS.CONNECTION_ID_LENGTH, no configuration definition available!
From debug in method org.eclipse.californium.elements.configConfiguration.add(Properties properties)

Allowed definitions is only COAP.*

There is some other technique to load DTLS configuration or I am missing something?

I guess, you missed to read the javadoc.

Though one of the features of the new configuration was to support "modularization", it's required to provide the modules you want to use (ahead of loading the values from a stream).
Two way are supported to do so:

• static approach: use the DtlsConfig.register(), CoapConfig.register(), and UdpConfig.register().
• (more) dynamic approach: use Configuration(ModuleDefinitionsProvider... providers). You may add custom definitions just before reading the stream.

Thank you! Got it!

You're welcome.

Just to mention: If you made some experience with the new Configuration (bad or good :-), feedback will be very welcome. See issues #1708 and #1709.
