https://devzone.nordicsemi.com/f/nordic-q-a/26217/nrf52840-wlanDear Nordic, nRF52840 is very good solution and we are planning below. What I want to do: WLAN Firmware to be stored in nRF52840 Flash nRF52840 Flash is sufficient for storage a WLAN FW nRF52840 control a WLAN through SPI When nRF52840en-USTelligent Community 13Tue, 24 Oct 2017 10:29:19 GMThttps://devzone.nordicsemi.com/thread/103245?ContentTypeID=1Tue, 24 Oct 2017 10:29:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e016d98c-3877-43b0-bcdb-47ebe4b81749bjorn-spockeli<p>If I understand you correctly you want to control a external WiFi chip using the SPI peripheral of the nRF52840? If that is the case, do you have a specific chipin mind? Could you also elaborate a bit on why you want to store the firmware of the WiFi chipon the nRF52840? Is it for updating the firmware of the WiFi chip?</p> <p>We have a SPI Master driver in our SDK, please see <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.1.0/hardware_driver_spi_master.html?cp=4_0_0_2_12">this</a> page on our Infocenter.</p> <p>You can find a SPI Master driver example project in our SDK under \examples\peripheral\spi, see <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.1.0/spi_master_example.html?cp=4_0_0_4_6_34">this</a> Infocenter page for more information on the example.</p><div style="clear:both;"></div>
