// Example sketch showing how to create a simple messageing client |
|
// with the RH_RF95 class. RH_RF95 class does not provide for addressing or |
|
// reliability, so you should only use RH_RF95 if you do not need the higher |
|
// level messaging abilities. |

// It is designed to work with the other example rf95_server |
|
// Tested with Anarduino MiniWirelessLoRa, Rocket Scream Mini Ultra Pro with |
|
// the RFM95W, Adafruit Feather M0 with RFM95 |
