I use the SPI slave function on 51422. When I send a byte(0x31) to 51422 SPI slave from master, 51422 will back a byte (0xAA - DEF byte) to master. Why?
I send 0x31 every 1 seconds, but I always get 0xAA. Why??

Hi,
That indicates that an ignored transaction has occurred (DEF register is set to '0xaa' in the SDK example).
Best regards Håkon
I use STM32 MCU for SPI master side and Nordic for SPI slave side. How can I mark sure that I send out the clock and data is consistent with Nordic? How can I know which mode I want to set it?
Thank you.
