QtBluetooth on Windows not working
-
I've had the same issue just a few days ago. You need to use MSVC compiler instead of MinGW, then it works.
Well, kind of works because BT support on Windows is very weak.

What a kind way to phrase that, not what would come to my mind.....
Also, the success of QtBluetooth highly relys on the Windows version, I would recommand upgrading to the lastest one possible.

Heh, yeah, the sentence you read is not the first one I wrote :P Although in my recent experience, Windows itself is also not particularly good with bluetooth, especially Low Energy variety.

Indeed. Different versions of Windows 10 work differently, Windows 8.1 comes with extra bunch of crashes...

To be fair, there is a lot of work ongoing to improve the Windows/Bluetooth experience.
See https://codereview.qt-project.org/#/q/status:merged+branch:wip/win,n,z for reference. However, this branch is not ready for production yet, but can already be compiled from end-users for testing purpose.

@sierdzio could you please tell me how to set up the MSVC compiler? When I try to build my program with it, it says "Could not find the executable, plesase specify one" and gives a lineEdit to browse. so with path do i have to state?

Did you already install Visual Studio or Microsoft Build Tools and Qt for Visual Studio?

In short, it's simple:
- download and install Microsof Visual Studio (it's free nowadays), make sure to check C++ download option (you don't need any of the rest: .Net, embedded, other platforms, Python and whatnot)
- open Qt Maintenance Tool and add MSVC 2017 package for your Qt version
- that's it, Qt Creator should now recognize that version, you just need to select it for your project in project settings

@sierdzio thank you for your answer. Now it's being detected successfully. However, when I run debug mode it produces "unexpected CDB Exit: The CDB process terminated". Do you know what might be the cause? I have researched this a bit but did not reach any solution yet.

Apart from knowing that CDB is the MSVC debugger I know nothing about it, sorry ;-)

I may be of help here :)

IIRC MSVC installation does not come automatically with the c++ debuger.
You'll need to download and install the Windows Software Developer Kitto be found here, I think. It's been a while when I installed it.

Hi
Can be many reasons
https://forum.qt.io/topic/69130/unexpected-cdb-exitAlso, are you using Creator Or Visual Studio to run it?
Ahh, @J-Hilk beat me to it :)
You might need the standalone debugger if running from Creator. -
