Hello Alex,

I am new to SPI protocol APIs for nRF52840 DK board. I have gone through the earlier posts of this ticket. Suppose if I connect two devices that are flashed with the example codes of SPI and SPIS in either of them respectively, how can I check if the data is transferred or not? Apart from connecting digital signal analyser at the MOSI pin of the SPI master controller.

thanks.

Thank you for your quick and friendly reply.

I have tested the MISO cable according to your advice.

The cable used for MISO was in poor contact.

SPI and SPIS are working well.

Hey alex,

We need some more information:

What exactly did you receive?
Have you made sure that MISO is properly connected on the SPI master?
Have you looked at the communication lines with a digital signal analyzer?
