README.md

About

This is an additional gcoap example, but with enabled DTLS. It only provides a custom configured makefile, while the code is a symlink to the original gcoap example. Therefore, the infos and usage notes of the other README also applies to this example.

Please note, that with DTLS the default port is 5684 and not 5683, thus CoAP requests must be sent to this port.

Since DTLS has higher memory and ROM requirements, more boards are blacklisted for this example compared to the non-DTLS gcoap example.

CoAP query with DTLS enabled

With DTLS enabled the server can be queried using the default DTLS pre-shared key from the tinydtls_keys.h file.

./coap-client coaps://[fe80::1843:8eff:fe40:4eaa%tap0]/.well-known/core -k "secretPSK" -u "Client_identity"
