You also have to set what instance you want to use of the SPI. for example CONFIG_NRFX_SPI1 or CONFIG_NRFX_SPIM1, etc.

My guess as to why you can send more in the nRF5 SDK than in NCS is because you've set different buffer and tx/rx lengths in the two projects you're running.

Thanks,

but when I use nrfx drivers I can't enable

CONFIG_NRFX_SPI=y in prj.conf, is there another way enable it.

and

in segger IDE I can send more data in

nrfx_spim_xfer(); but in ncs I can't send that much data ,so what to do for increase number of bytes

Either is fine, and it's mostly up to personal preference. I'm probably biased, but personally I prefer the nrfx drivers in general, as I'm most familiar with them.

The API reference of Zephyrs SPI driver is available here, and the nRF Connect API is available here for SPI, and here for SPIM.

Best regards,
