.. _zoap-client-sample:

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

Sample output
=============

.. code-block:: console
