Newly Optimized RF24Network Layer  v1.0.7
2014-2015 - Optimized RF24 Network Layer for NRF24L01 radios
helloworld_rx.ino

Simplest possible example of using RF24Network. Put this sketch on one node, and helloworld_tx.pde on the other. Tx will send Rx a nice message every 2 seconds which rx will print out for us.
