TBH i'm quite confused by the Windows handling of Bluetooth...
my driver decided to disappear a couple of times and only re-install
fixed it. i don't know why.

i will look at our discovery methods when i get more time.
i think i saw that we aren't using the official Qt BLE way of
discovery for BLE devices.
