/**
 * 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.
