Semtech / Mbed 2 deprecated SX1280PingPong

Simple Ping-Pong demo application between two SX1280 demo boards. 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

Dependencies:   SX1280Lib mbed

This code is made to run without the screen and the user may observe some glitches on the display if it remains connected during the Ping Pong demo.
