Another way to understand the pin

Using Arduino Networking, Protocols, and Devices
1

Although I have read the datasheet of NRF24L01 but it was still a little bit hard to understand the function of each of the pin. Can anyone please make an easy way to show that how an NRF24L01 used and on which pin it used to during Master/Slave(Transmit/Receive)?

This may seem easier to read for me, like:

Transmitter:
CE - 1 (Chip Enable 1 for Sending/Listening?)
CSN - ???
SCK - ???
MOSI - 1 (Used to transmit to the Slave?)
MISO - 0 (1 If Receive from the Slave?)
IRQ - (I'm not sure if it's used)

Receiver:
CE - 1 (Sending/Listening?)
CSN - ???
SCK - ???
MOSI - 1 (Receive from the Transmitter)
MISO - 0 (1 If Transmit to the Master?)
IRQ - (I'm not sure if it's used)

Please do give me the right correction because I knew there must be lots of errors!
Your little help may pull me a big step forward!

Maybe https://arduino-info.wikispaces.com/Nrf24L01-2.4GHz-HowTo could enlighten you.

I suspect you did not intend to have smileys in your Original Post.

Have a look at this Simple nRF24L01+ Tutorial

MOSI MISO and SCK are the regular SPI connections. For both nRF24s the Arduino will be the master.

CSN is the Chip-select pin used as part of the SPI process.

CE is the pin that puts the nRF24 into transmit mode.

So you mean both the transmitter and receiver will be the master?

The receivers Arduino and the transmitters Arduino will be SPI masters.

But what can I do with the MISO and MOSI?
Ain't that one of them must be the slave?

Can? No, you should connect those to the NRF of the respective Arduino.

Pins are neither master nor slaves, what do you mean?

SPI always has 2-way communication so at any time data flows out from the master on the MOSI pin and in to the master on the MISO pin
