-// This file contains the functions to do management over UDP
-// We could make use of the LoRa message function for the Gateway sensor
-// itself. However the functions defined in this file are not sensor
-// functions and activating them through the LoRa interface would add
-// no value and make the code more complex.
-//
-// So advantage: Simple, and does not mess with TTN setup.
-//
-// Disadvantage of course is that you need to setup you own small backend
-// function to exchange messages with the gateway, as TTN won't do this.
-//
-// XXX But, if necessary we can always add this later.
