Hi Luca, cheers for your response. After an hour of SDK hacking, I got it working - now just need to pull the changed SPIS code out of the SDK and into my own project.

My solution is here: devzone.nordicsemi.com/.../spi-slave-comms-using-byte-count-eg-rx-buffer-full-rather-csn-chip-select-to-indicate-end-of-spi-transaction

Hi,

It's been a while now.. but no, we had to use the SPIS CS signal to end the transaction.

Did you ever get this working. I am in the same boat, the master hold CS Low beyond the end of the transfer as it expects to get the ACK/NAK before CS is released (raised). I need an 'end' event once my SPIS buffer (8 bytes) has been filled by the SPI Master.

Okay, I see. Could you try the following, and check if it makes any difference: NRF_SPIS1->INTENSET |= (SPIS_INTENSET_ENDRX_Enabled << SPIS_INTENSET_ENDRX_Pos);

Yes, when the CS goes high. But I also want to get the interrupt when the buffer is full (ENDRX event).

For transmission/reception is completed, do you receive the event EVENTS_END?
