I have exactly the same problem see my topic. Actually I did not find any solution

@martial123 These dongles are needed, if you use the node.js Bluetooth Low Energy library called "noble" (this video is actually about how to use noble), I only linked it because he also explains how to use Zadig. I don't know if your Dongle, that you have know, will work with Qt BluetoothLE library, just try it, if not, you could then try one of these listed in the video .
