SX1272 LoRa RF module PingPong Demo

Dependencies:   SX1272Lib XRange_mbed_src

XRange SX1272 LoRa RF module https://www.netblocks.eu/xrange-sx1272-lora-datasheet/

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
