In addition to |NCS| samples, it is possible to run selected networking samples with Wi-Fi®, provided and maintained as part of the upstream Zephyr project.
The following list specifies samples that are currently supported with the Wi-Fi driver:

* :zephyr:code-sample:`dhcpv4-client`
* :zephyr:code-sample:`dns-resolve`
* :zephyr:code-sample:`ipv4-autoconf`
* :zephyr:code-sample:`mdns-responder`
* :zephyr:code-sample:`mqtt-publisher`
* :zephyr:code-sample:`mqtt-sn-publisher`
* :zephyr:code-sample:`coap-client`
* :zephyr:code-sample:`coap-server`
* :zephyr:code-sample:`sockets-echo`
* :zephyr:code-sample:`async-sockets-echo`
* :zephyr:code-sample:`sockets-echo-client`
* :zephyr:code-sample:`sockets-echo-server`
* :zephyr:code-sample:`sockets-http-get`
* :zephyr:code-sample:`sntp-client`
* :zephyr:code-sample:`syslog-net`
* :zephyr:code-sample:`telnet-console`

Configuration
*************

|config|

Before you build a sample, you must configure the following Wi-Fi credentials in the :file:`overlay-nrf700x.conf` file:

* :kconfig:option:`CONFIG_WIFI_CREDENTIALS_STATIC_SSID` - Network name (SSID)
* :kconfig:option:`CONFIG_WIFI_CREDENTIALS_STATIC_PASSWORD` - Password
* :kconfig:option:`CONFIG_WIFI_CREDENTIALS_STATIC_TYPE` - Security type (Optional)

.. note::
   You can also use ``menuconfig`` to configure Wi-Fi credentials.

See :ref:`zephyr:menuconfig` in the Zephyr documentation for instructions on how to run ``menuconfig``.

Building and running
********************

To build the sample with |VSC|, follow the steps listed on the `How to build an application`_ page in the |nRFVSC| documentation.
See :ref:`building` for other building scenarios, :ref:`programming` for programming steps, and :ref:`testing` for general information about testing and debugging in the |NCS|.

An overlay file, ``overlay-nrf700x.conf`` is provided to all Zephyr samples, which configures the sample to run with the Wi-Fi driver.

To build Zephyr samples for the nRF7002 DK, use the ``nrf7002dk/nrf5340/cpuapp`` build target.
The following is an example of the CLI command:

.. code-block:: console

   west build -b nrf7002dk/nrf5340/cpuapp -- -DEXTRA_CONF_FILE=overlay-nrf700x.conf

To build for the nRF7002 EK with nRF5340 DK, use the ``nrf5340dk/nrf5340/cpuapp`` build target with the ``SHIELD`` CMake option set to ``nrf7002ek``.
The following is an example of the CLI command:

.. code-block:: console

   west build -b nrf5340dk/nrf5340/cpuapp -- -DSHIELD=nrf7002ek -DEXTRA_CONF_FILE=overlay-nrf700x.conf

For additional details about running a sample, refer to the respective sample in Zephyr’s Samples and Demos documentation.
