/**
* Example for Getting Started with nRF24L01+ radios.
*
* This is an example of how to use the RF24 class. Write this sketch to two
* different nodes. Put one of the nodes into 'transmit' mode by connecting
* with the serial monitor and sending a 'T'. 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.
* This is an example of how to use the RF24 class to communicate on a basic level. Write this sketch to two
* different nodes. Put one of the nodes into 'transmit' mode by connecting with the serial monitor and
* sending a 'T'. 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.
* Note: For a more efficient call-response scenario see the GettingStarted_CallResponse.ino example.
* Note: When switching between sketches, the radio may need to be powered down to clear settings that are not "un-set" otherwise

TMRh20 2014 - Updates to the library allow sleeping both in TX and RX modes:

/**
* Example RF Radio Ping Pair which Sleeps between Sends
*
* This is an example of how to use the RF24 class to create a battery-
* efficient system. It is just like the GettingStarted_CallResponse example, but the
* ping node powers down the radio and sleeps the MCU after every
* ping/pong cycle, and the receiver sleeps between payloads.
*
* 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.

/**
* Example RF Radio Ping Pair which Sleeps between Sends
*
* This is an example of how to use the RF24 class to create a battery-
* efficient system. It is just like the pingpair.pde example, but the
* ping node powers down the radio and sleeps the MCU after every
* ping/pong cycle.
*
* As with the pingpair.pde example, 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.
