Cannot establish communication

[mohitathwani]

I am trying to establish a connection between my Arduino Uno and RPi.

I followed the connections and run the Getting Started example on the Arduino and "pongtest" on the Pi

Output on Arduino -

I cannot establish communication between the 2 devices. I have checked, double checked and triple checked the connections. They're all correct. Using connections as mentioned in http://hack.lenotta.com/arduino-raspberry-pi-switching-light-with-nrf24l01/

Also, both devices are in the same room so range is not a problem.
