// Example sketch showing how to create a simple messageing server

// with the RH_NRF24 class. RH_NRF24 class does not provide for addressing or
|
|
// reliability, so you should only use RH_NRF24 if you do not need the higher

|
// level messaging abilities.

// Tested on Uno with Sparkfun NRF25L01 module

|
// Tested on Anarduino Mini (http://www.anarduino.com/mini/) with RFM73 module
