Thanks Håkon Alseth for replying. Is there a USB project that you recommend to study having this HID Feature Request implemented? I've read that the keyboard project

SDK/examples/peripheral/usbd_hid_composite

enable the nRF52840 devboard to receive infos through USB to update the LED status of the keyboard. Is it that project that I should study, perhaps. And what do you recommend in order to test it in a quick way? Is there some USB tool that I can use to do quick tests and send USB data to endpoint out 0? Thanks for your kindness

Hi,

The function usbd_setup_SetFeature() is for things like remote wakeup etc. The data itself is a 8 byte packet, with format shown in nrfx_usbd.h::nrfx_usbd_setup_t.

Are you looking for "HID Feature Request"? This is unfortunately not implemented in app_usbd_hid.c for both set and get feature request.

Kind regards,

Håkon
