Hello everyone.

I just got a xiao mcu to use with a nrf24 as receiver. I spent the whole day trying to figure out how to set it up, to no avail.

So far, here is my code (below). I finally have SPI OK, after setting manually every pin. But I get Radio Fail and nRF FAIL as well. The wiring obviously is pristine and has been checked more times than I dare to say.

Any help or hint would be appreciated, thanks in advance !

Edit : Output is :

SPI OK

RADIO FAIL

nRF FAIL

SPI Speedz = 10 Mhz

DYNPD/FEATURE = 0x00 0x00

Data Rate = 1 MBPS
