* Function: RX_Mode();

* Description:
* This function initializes one nRF24L01 device to
* RX Mode, set RX address, writes RX payload width,
* select RF channel, datarate & LNA HCURR.
* After init, CE is toggled high, which means that
* this device is now ready to receive a datapacket.

Now, power on both Arduino
®
and connect the RX to the PC via USB. Open the IDE serial port monitor, change
the baud rate to 9600 bps, and you can see the received data.
If you want to change the Arduino
®
pin connection to the module, just modify the definition on the nFR24L01.
