Interfacing of NRF24l01 with ultrasonic sensor

I'm basically newbie to arduino and need help for a project im working on.
i know what im working with and what i need so here it goes
I have:
Arduino uno x1
arduino nano x1
NRF24l01 x2
ultrasonic sensor x1

so i'll be connecting an NRF sensor with ultrasonic sensor to arduino nano which will send a signal to arduino UNO if any object is in front of the ultra sonic sensor so the distance i need to cover is almost 10 to 12m so basically i need a clear view on how to do this im not asking for codes direct because i want to learn how to do this so if i need any other components please let me know i read in a forum that ill have to use a bypass capacitor across 3.3v and GND of arduino uno at reciever side and what should i keep at reciever side arduino UNo or a nano.

Thanks in advance!

Have a look at this Simple nRF24L01+ Tutorial.

Wireless problems can be very difficult to debug so get the wireless part working on its own before you start adding any other features.
