Wi-Fi: Zephyr networking samples

In addition to nRF Connect SDK 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:

• DNS resolve

• IPv4 autoconf client

• mDNS responder

• MQTT publisher

• MQTT-SN publisher

• CoAP service

• Asynchronous echo server using poll()

• Echo client (advanced)

• Echo server (advanced)

• HTTP GET using plain sockets

• SNTP client

• Remote syslog

• Telnet console

Building and running

To build the sample with Visual Studio Code, follow the steps listed on the How to build an application page in the nRF Connect for VS Code extension documentation. See Building an application for other building scenarios, Programming an application for programming steps, and Testing and optimization for general information about testing and debugging in the nRF Connect SDK.

A Wi-Fi snippet configuration 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 board target. The following is an example of the CLI command:

west build -b nrf7002dk/nrf5340/cpuapp -S wifi-ipv4

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

west build -b nrf5340dk/nrf5340/cpuapp -S wifi-ipv4 -- -DSHIELD=nrf7002ek -DSB_CONFIG_WIFI_NRF70=y

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