Re: [cf-dev] Californium CoAP client question

Hi Kai, 

Thanks for the response. I was looking to do it for both non and secure connections. So is there a way to "disconnect" a device or close session using DTLS?

Thanks, 

Alejo

Hi Alejo,

not sure what you expect such a close to achieve. Since CoAP runs over UDP there is no "connection" per se being established as with TCP. Thus, when using plain CoAP there is no need for closing a connection. However, if you run CoAP over DTLS, e.g. when using a URI like "coaps://...") then you might be interested in closing the (logical) DTLS session that the CoapClient has established with the server. Is that what you're looking for?

Hi guys,

I have the following concern.

How can I do to unregister (or disconnect) a device from a CoAP client.
I'm initializing it like coapClient = new CoapClient(...).
Does the client have something like a "disconnect/close" method?

Thanks! 

Alejo
