    @sierdzio said in QtBluetooth on Windows not working:

    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.

    Also, the success of QtBluetooth highly relys on the Windows version, I would recommand upgrading to the lastest one possible.

    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.

      Regards

      Qt has to stay free or it will die.

          I've had the same issue just a few days ago. You need to use MSVC compiler instead of MinGW, then it works.

          @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 ;-)

                    IIRC MSVC installation does not come automatically with the c++ debuger.
                    You'll need to download and install the Windows Software Developer Kit

                    to be found here, I think. It's been a while when I installed it.

                    Q: What's that?
                    A: It's blue light.
                    Q: What does it do?
                    A: It turns blue.

                      Hi
                      Can be many reasons
                      https://forum.qt.io/topic/69130/unexpected-cdb-exit

                      Also, 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.

                        @J.Hilk @mrjj thank you for your answers. I already had an SDK installed. I reinstalled it, but the error remains :/ could it be some version mismatch? How can I check this?

                          Check the kits and see if any red marks.
