Example of libcoap running on RIOT
==================================

To build the examples, do

    $ make

This will

* download RIOT from the upstream git sources.
* update the RIOT environment with pkg/libcoap, examples/libcoap-client
  and examples/libcoap-server taken from pkg_libcoap/, examples_client/
  and examples_server/ respectively.
  (updates RIOT's libcoap code to the latest committed version in your
   environment, along with any modified files).
* build the client application.
* build the server application.

To run (and/or rebuild) the server application

* cd RIOT/examples/networking/coap/libcoap_server
* make RIOT_CI_BUILD=1
* make term
* (at the shell prompt) coaps start
* (or at the shell prompt) coaps stop

The server creates a resource for 'time' with a query 'ticks'.  This is
reported for `.well-known/core`. The work flow for adding more resources does
not differ from regular libcoap usage.

To run (and/or rebuild) the client application

* cd RIOT/examples/networking/coap/libcoap_client
* make RIOT_CI_BUILD=1
* make term
* (at the shell prompt) coapc coap://[ip-6-address]/some/path

The client will try to connect to the URI defined in app.config named
CONFIG_LIBCOAP_CLIENT_URI (unless overridden by running 'make menuconfig'),
or as specified in the parameter after the coapc.

Note to developers
==================

PKG_VERSION= in pkg_libcoap/Makefile needs updating if you need a different
version of libcoap to get initially installed into RIOT/pkg/libcoap.

Kconfig support is available.
