Yes, it's correct. See here. You need CSN to tell the SPI Slave to listen to the communication.

One question about the connection between both nrf24LE1. Is it correct that on the SPI master side the MMISO,MMOSI,MSCK and on the SPI slave side the SMISO,SMOSI,SSCK have to be used and connected like the following?

Master Slave

MMISO --- SMISO MMOSI --- SMOSI MSCK --- SSCK

The SCSN is not neccessary, right? EDIT: Looking in your example i see that the SCSN can be used to initialze something when CSN goes low and starting some actions when CSN goes high.

Hi,

We have an example for SPI master and slave. Maybe it won't fulfill what you asked for but it's a good reference.
