Alberto Escolar Piedras cb53e40ff9 drivers uart_native_posix: rename to native_pty and support N instances Rename the driver from uart_native_posix to uart_native_pty. Including renaming the DTS compatible, and kconfig options, deprecating the old ones. And refactor the driver, generalizing it, so we can have any number of instances. Note that, unfortunately generalizing to N instances cannot be done without a degree of backwards compatibility breakage: This driver was born with all its configuration and selection of the instances based on kconfig. When the driver was made to use DT, it was done in a way that required both DT and kconfig needing to manually coherently enable the 2nd UART. This has now been fixed, which it means only DT is used to decide how many instances are avaliable, and UART_NATIVE_POSIX_PORT_1_ENABLE is just ignored. Including: * Deprecate UART_NATIVE_WAIT_PTS_READY_ENABLE: the options is always on now as it has no practical drawbacks. * Deprecate UART_NATIVE_POSIX_PORT_1_ENABLE: DTS intanciation defines it being available now. * Rename a few functions and in general shorten pseudo-tty/pseudo- terminal to PTY instead of PTTY.

.. zephyr:code-sample:: coap-server
   :name: CoAP service
   :relevant-api: coap coap_service

   Use the CoAP server subsystem to register CoAP resources.

Overview
********

This sample shows how to register CoAP resources to a main CoAP service.
The CoAP server implementation expects all services and resources to be
available at compile time, as they are put into dedicated sections.

The resource is placed into the correct linker section based on the owning
service's name. A linker file is required, see ``sections-ram.ld`` for an example.

This demo assumes that the platform of choice has networking support,
some adjustments to the configuration may be needed.

The sample will listen for requests in the CoAP UDP port (5683) in the
site-local IPv6 multicast address reserved for CoAP nodes.

The sample exports the following resources:

.. code-block:: none

   /test
   /seg1/seg2/seg3
   /query
   /separate
   /large
   /location-query
   /large-update

These resources allow a good part of the ETSI test cases to be run
against coap-server.

Building And Running
********************

This project has no output in case of success, the correct
functionality can be verified by using some external tool such as tcpdump
or wireshark.

See the `net-tools`_ project for more details

This sample can be built and executed on QEMU or native_sim board as
described in :ref:`networking_with_host`.

Use this command on the host to run the `libcoap`_ implementation of
the ETSI test cases:

.. code-block:: console

   sudo ./examples/etsi_coaptest.sh -i tap0 2001:db8::1

To build the version supporting the TI CC2520 radio, use the supplied
prj_cc2520.conf configuration file enabling IEEE 802.15.4.

Wi-Fi
=====

The IPv4 Wi-Fi support can be enabled in the sample with
:ref:`Wi-Fi snippet <snippet-wifi-ipv4>`.
