nrf7002 with STM32 host

joel-jc

Hi,

I have a zephyr project using an STM32U5 as the main MCU. We are looking to add WiFi capabilities and are exploring WiFi companion chip options, and are considering using the nrf7002. I had the following questions on this:

- Are non-nordic host MCUs supported for the nrf7002? I see in the Kconfig.nrf700x that the EXPERIMENTAL flag is set for anything thats not hosted by nrf53x or nrf91x.

- My project currently uses vanilla Zephyr, would switching to to the nRF Connect SDK be required to access the nrf7002 driver?

- Are there licensing concerns with this kind of configuration? Its my understanding that the nRF Connect SDK is licensed for use with Nordic parts, so is it valid to run NCS code on an STM32 if it is utilising a Nordic companion chip?

Thanks in advance for any help!

    Hi

    Due to the summer vacation period we are currently understaffed, so delayed replies must be expected. I am sorry about any inconvenience this might cause.

    1. Currently, only nRF SoCs are supported as hosts for the nRF7002. All other hosts are indeed only experimental as of now. It should be possible to use other host MCUs, but it's not something we've tested or support as of now.

    2. Yes, you'll need to use the nRF Connect SDK to access the nRF7002 driver.

    3. The license for the nRF Connect SDK is explained here in our documentation. I think the regional sales manager (RSM) of your area should be able to provide better information on what exactly is allowed and not. Let me know if you need help to get in touch with your RSM.

    Best regards,

    Simon
