Re: [leshan-dev] Californium and DTLS

Hi Ramon,

leshan needs to be configured with DTLS support during start-up. DTLS support is provided by means of Californium's Scandium component. You can take a look at both Scandium's example code [1] as well as the leshan standalone server code [2] in order to better understand how to configure Scandium support in leshan.

Once leshan is running with Scandium support configured, a client can establish a secure connection by means of DTLS by using the coaps:// URI scheme or by explicitly connecting to the DTLS port on the server.

HTH,

Kai

Dear Leshan developers,

How can a secure connection via DTLS be established with Leshan? I'm informed this can be done with the appropriate security setting during the registration procedure (as per LWM2M specification), with that said, is a secure connection automatically established if the URI is prefixed with coaps:// ?

Best regards,

Ramon Mato.
