+// rf95_mesh_server3.cpp
+// -*- mode: C++ -*-
+// Example sketch showing how to create a simple addressed, routed reliable messaging server
+// with the RHMesh class.
+// It is designed to work with the other examples rf95_mesh_*
+// Hint: you can simulate other network topologies by setting the
+// RH_TEST_NETWORK define in RHRouter.h
+
+// Mesh has much greater memory requirements, and you may need to limit the
+// max message length to prevent wierd crashes
+//
+// 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_mesh_server3.
+// 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.
