Hi folks,
I found that there is a WIFI sample application with the nRF52840 listed as supported development kit. So I tried to build that one but got strange errors regarding nrf700x. Here is the output of the build command:
west build -b nrf52840dk_nrf52840

If I try to build a simple example like the hardware ID one, it builds just fine.
I am a little confused why there is the nrf700x mentioned. Do I need to connect the companion chip to the devkit to be able to run this sample application? Where can I find the documentation on doing so? And even if I would have done so, why is the sample application code not building?
Thank you very much.
Best Regards,
M. Hummels
