When using an IDE (e.g. Eclipse, Qt Creator), the project name gets displayed. This greatly simplifies the navigation between projects when having many of them open at the same time. Naming every project "NONE" defeats this functionality. This patch tries to use sensible project names while not duplicating too much of what is already represented in the path. This is done by using the name of the directory the relevant CMakeLists.txt file is stored in. To ensure unique project names in the samples (and again, in the tests folder) folder, small manual adjustments have been done. Signed-off-by: Reto Schneider <code@reto-schneider.ch> |

CoAP client
###########
Overview
********
A simple CoAP client 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 described in :ref:`networking_with_qemu`.
