SX1272 Ping Pong Demo Application

Dependencies:   SX1272Lib mbed

Fork of SX1272PingPong by Semtech

Simple Ping-Pong demo application between two SX1272MB2xAs demo board.

Application demonstrating simple Tx/Rx between two boards. By default, each board starts as a "master" and will transmit a "Ping" message, and then wait for an answer. The first board receiving a "Ping" message will become a slave and answer the "master" with a "Pong". The Ping-Pong is then started
