/**
* Example RF Radio Ping Pair
*
* This is an example of how to use the RF24 class. Write this sketch to two different nodes,
* connect the role_pin to ground on one. The ping node sends the current time to the pong node,
* which responds by sending the value back. The ping node can then see how long the whole cycle
* took.
