nrf905_client.pde

// nrf905_client.pde
// -*- mode: C++ -*-
// Example sketch showing how to create a simple messageing client
// with the RH_NRF905 class. RH_NRF905 class does not provide for addressing or
// reliability, so you should only use RH_NRF905 if you do not need the higher
// level messaging abilities.
// It is designed to work with the other example nrf905_server.
// Tested on Teensy3.1 with nRF905 module
// Tested on Arduino Due with nRF905 module (Caution: use the SPI headers for connecting)
