I bought the hardware as i thought it would be a snap on thing. But it turned out to be pretty cumbersome. I have both the Nano's powered up and the NRF24L01 is powered from the 3.3v of the Nanos. 4.7uf capacitor is coupled between the power lines of the NRF24L01 modules. Both are powered on and when checked the serial data from the received it is saying "Radio not available". Lost as to know what should i check now. I am a noob btw. Could you guys give me some directions on this please.

RX/TX programs are as is from here https://arduino-info.wikispaces.com/Nrf24L01-2.4GHz-HowTo

Use an external 3.3 volt power source for the NRF modules, I had the same problem....the nano cannot supply enough current to power these when the start transmitting. Once I set up external power they worked perfectly.

I have 5 Arduino running the NRF boards off of the internal 3.3 volt supply. One is an Uno and the others are Nano's. No caps on any supply lines. The Uno is running an Ethernet shield AND the NRF board!!
