// rf95_router_test.cpp
// -*- mode: C++ -*-
//
// Test code used during library development, showing how
// to do various things, and how to call various functions
//
// Requires Pigpio GPIO library. Install by downloading and compiling from
// http://abyz.me.uk/rpi/pigpio/, or install via command line with
// "sudo apt install pigpio". To use, run "make" at the command line in
// the folder where this source code resides. Then execute application with
// sudo ./rf95_router_test.
// Tested on Raspberry Pi Zero and Zero W with LoRaWan/TTN RPI Zero Shield
// by ElectronicTricks. Although this application builds and executes on
// Raspberry Pi 3, there seems to be missed messages and hangs.
// Strategically adding delays does seem to help in some cases.
//(10/6/2019) Contributed by Brody M. Based off rf22_router_tester.pde.
// Raspberry Pi mods influenced by nrf24 example by Mike Poublon,
// and Charles-Henri Hallard (https://github.com/hallard/RadioHead)
