https://devzone.nordicsemi.com/f/nordic-q-a/110927/using-the-nrf7002-without-zepher-on-a-custom-host-cpuWe are hoping to replace and atmel WINC1500 with a Nordic nrf7002 on an existing design. This will make our product WiFi 6 compatible. We use the WINC1500 in passthrough mode so it should operate just like a nrf7002. It seems a lot of the driver codeen-USTelligent Community 13Tue, 07 May 2024 15:17:48 GMThttps://devzone.nordicsemi.com/thread/482344?ContentTypeID=1Tue, 07 May 2024 15:17:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ed1db399-5c38-42a9-8ab3-924a2a0a9d69Amanda Hsieh<p>HI,</p> <p><span>You can take a look at the&nbsp;</span><a href="https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/drivers/wifi/nrf700x/nrf700x.html#api_documentation">nRF Wi-Fi driver</a>&nbsp;and&nbsp;<a href="https://devzone.nordicsemi.com/f/nordic-q-a/100494/how-where-is-the-nrf7002-initialized-by-the-nrf5340-on-the-nrf7002dk-in-the-wifi-sta-example-project?ReplyFilter=Answers&amp;ReplySortBy=Answers&amp;ReplySortOrder=Descending">this post</a><span>&nbsp;on&nbsp;</span><span>how the nRF7002 is initialized.&nbsp;</span></p> <p></p> <p>To use nRF7002 via SPI, it needs to establish a connection between the nRF7002 and the host MCU (like nRF5340 or nRF9160).
