This commit rewrites the example so that the registration loop is run inside the main() function instead of running the standalone submodule of epsim. It also adapts the example application to parse the RD UDP endpoint locally and provide this to epsim's register() function.
CoRE Resource Directory: Simple Endpoint Example
This example shows how a node can register with a CoRE resource directory using the simple registration procedure as described in draft-ietf-core-resource-directory-15, section 5.3.1.
When running this example, you must define the RD server's IPv6 address
statically, using the RD_ADDR environment variable:
RD_ADDR=\\\"abc:0815::123\\\" make all
Per default, this is set to some random global address (affe::1) for compile
test reasons. So change it!
Additionally, you can change the RD server's port by overriding the RD_PORT
variable:
RD_ADDR=\\\"affe::bee\\\" RD_PORT=12345 make all
The registration lifetime is set for demonstration purposes to a rather short
time of 60s in this example. You can easily override that value using the
RD_LT variable:
RD_ADDR=\\\"abc::def\\\" RD_LT=3600 make all ...
