+/* 
+ *
+ *  Filename : rpi-hub.cpp
+ *
+ *  This program makes the RPi as a hub listening to all six pipes from the remote sensor nodes ( usually Arduino )
+ *  and will return the packet back to the sensor on pipe0 so that the sender can calculate the round trip delays
+ *  when the payload matches.
+ *  
+ *  I encounter that at times, it also receive from pipe7 ( or pipe0 ) with content of FFFFFFFFF that I will not sent
+ *  back to the sender
+ *
+ *  Refer to RF24/examples/rpi_hub_arduino/ for the corresponding Arduino sketches to work with this code.
+ * 
+ *  
+ *  CE is not used and CSN is GPIO25 (not pinout)
+ *
+ *  Refer to RPi docs for GPIO numbers
+ *
+ *  Author : Stanley Seow

+ *  date   : 6th Mar 2013
+ *
+ * 03/17/2013 : Charles-Henri Hallard (http://hallard.me)
+ *              Modified to use with Arduipi board http://hallard.me/arduipi
+ *						  Changed to use modified bcm2835 and RF24 library
