nRF52840+WLAN

[joyfulsound]

Dear 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 nRF52840 Booting, WLAN FW will be downloaded
• After booting, nRF52840 control WLAN through SPI

Is this possible from a nRF52840 point of view ? and could you share a sample source if you have regarding this SPI driver?

Best Regards,

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?

We have a SPI Master driver in our SDK, please see this page on our Infocenter.

You can find a SPI Master driver example project in our SDK under \examples\peripheral\spi, see this Infocenter page for more information on the example.
