// rf95_router_client.cpp
|
||||
// -*- mode: C++ -*-
|
||||
// Example sketch showing how to create a simple addressed, routed reliable messaging client
|
||||
// with the RHRouter class.
|
||||
// It is designed to work with the other examples rf95_router_server*.
|
||||
//
|
||||
// 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_client.
|
||||
// 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.
|
||||
|
||||
//(9/20/2019) Contributed by Brody M. Based off rf22_router_client.pde.
|
||||
// Raspberry Pi mods influenced by nrf24 example by Mike Poublon,
|
||||
// and Charles-Henri Hallard (https://github.com/hallard/RadioHead)
