This example shows how a node can register with a CoRE resource directory using the simple registration process as described in draft-ietf-core-resource-directory-11, section 5.3.2.

The registration process needs an endpoint name as well as a lifetime for the registry entry. You can edit these values by overriding RDCLI_EP and RDCLI_LT:

CFLAGS="-DRDCLI_LT=\"7200\" -DRDCLI_EP=\"MyNode\"" make all

Per default, the node is looking for the CoRE RD at the all nodes link-local multicast address [FF02::1]:5683. To change the target address or port, simply override the RD_ADDR and RD_PORT variables, e.g.:

RD_ADDR=\\\"::1\\\" RD_PORT=12345 make all

or

RD_ADDR=\\\"abc:0815::123\\\" make all
