/*
* BLEAdvertising.cpp
*
* This class encapsulates advertising a BLE Server.
* Created on: Jun 21, 2017
* Author: kolban
*
* The ESP-IDF provides a framework for BLE advertising. It has determined that there are a common set
* of properties that are advertised and has built a data structure that can be populated by the programmer.
* This means that the programmer doesn't have to "mess with" the low level construction of a low level
* BLE advertising frame. Many of the fields are determined for us while others we can set before starting
* to advertise.
*
* Should we wish to construct our own payload, we can use the BLEAdvertisementData class and call the setters
* upon it. Once it is populated, we can then associate it with the advertising and what ever the programmer
* set in the data will be advertised.
