Using the APIs implemented by the C&C server, a GUI-based administration tool was created using the Qt5 framework and the Mosquitto MQTT client library was developed, allowing for the basic management of nodes. They were overlaid on top of a layout graphic of buildings.
While basically usable, it was found that a graphical tool was fairly complicated to develop. It was also limited to a single floor of a building, unless one were to have a really large map containing all of the floors with the nodes mapped onto this. This would have been quite clumsy, obviously.
In the source code provided with this chapter, the administration tool can be found as well, to serve as an example of how one could implement it. For the sake of brevity, the code for it has been omitted here.
