CoAP client
###########
Overview
********
A simple CoAP server showing how to retrieve information from a resource.
This demo assumes that the platform of choice has networking support,
some adjustments to the configuration may be needed.
This sample will make a GET request with path 'test' to the IPv6
multicast address reserved for CoAP nodes, so the URI can be
represented as:
.. code-block:: none
coap://[ff02::fd]:5683/test
Building and Running
********************
This project will print all the octets of the response received, more context can
be obtained by using a tool like tcpdump or wireshark.
See the `net-tools`_ project for more details.
It can be built and executed on QEMU as follows:
.. code-block:: console
make run
