* Full test on single RF pair

*
|

* This sketches uses as many RF24 methods as possible in a single test.
|

*
|
||||
* To operate:
|
||||
* Upload this sketch on two nodes, each with IRQ -> pin 2
|
||||
* One node needs pin 7 -> GND, the other NC. That's the receiving node
|
||||
* Monitor the sending node's serial output
|
||||
* Look for "+OK PASS" or "+OK FAIL"
