SX1276 Ping Pong FHSS Demo Application
Ping-Pong demo application using FHSS (Frequency Hoping Spread Spectrum) between two SX1276MB1xAs 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...
