| /* Simple Ping-Pong using address filtering for a FSK Radio/Modem | ||
| * | ||
| * In setup() below please adjust your country specific frequency ranges, | ||
| * as well as the Bandwidth/SpreadingFactor/CodingRate settings. | ||
| * | ||
| * They way this example works is that the device first listens for 5000ms. | ||
| * If it received a "PING" message, it considers itself a SLAVE. If not | ||
| * it considers itself a MASTER. A SLAVE waits for an incoming "PING" message, | ||
| * which it answers with a "PONG" message. A MASTER simply sends periodically | ||
| * every 1000ms) a "PING" message, and collects "PONG" replies while waiting. | ||
| * | ||
| * This variant makes use of address filter to comminicate between nodes. | ||
| * | ||
| * | ||
| * This example code is in the public domain. | ||
