When an app uses a construct such as: obj-y = main.o ../../../../samples/bluetooth/gatt/hrs.o in its makefile, it causes said object module to be built in the source tree, not in the object tree. When building massively parallel, this usually resuls on the files getting corrupted, leading to bugs such as: https://jira.zephyrproject.org/browse/ZEP-2316 https://jira.zephyrproject.org/browse/ZEP-2317 src/../../../../samples/bluetooth/gatt/.gap.o.cmd:3: warning: NUL character seen; rest of line ignored src/../../../../samples/bluetooth/gatt/.gap.o.cmd:4: warning: NUL character seen; rest of line ignored src/../../../../samples/bluetooth/gatt/.gap.o.cmd:5: *** missing separator. Stop. as multiple build are trying to touch the same file in the source tree and of course, race and causes a build bug. We have known about this issue for a long time, but it requires modifications in the build system that there is no time to tackle. A suggested workaround is to include the source files into a local .c file, so this is what this patch does, to remove the random noise.

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
