Bluetooth Library for BlueZ (Windows)

Bluetooth in Windows is a completely different animal. BlueZ is not supported in Windows at all. That simple_scan.c you're referring to will also not run on Windows. I'm working on a project to read Heart Rate Monitors and we found it's going to be a royal pain to do in Windows (see example here) so we went Linux with our project and are using BlueZ with Qt 5.5.
