Answer 1

You can use Eclipse Californium to start up your own DTLS based CoAP server. Take a look at the DTLS example in the source repository , that should get you started.

Alternatively, you can connect to the Eclipse Californium sandbox CoAP server at californium.eclipse.org:5684.

Here's how to do that using the openssl s_client tool:

openssl s_client -dtls1_2 -psk_identity password -psk 736573616D65 -connect californium.eclipse.org:5684

Answer 2

You can test coaps connection local like this

$ ./coap-server -A ::1 -k 1234 &
$ ./coap-client 'coaps://[::1]/' -k 1234 -u CoAP
