Qt Bluetooth module is non-functional

[Julian]

Hello Im having a problem trying to set up a Bluetooth server and I saw this topic:
https://forum.qt.io/topic/69087/error-qt-bluetooth-dummy-backend-running-a-problem-about-using-qbluetooth

Is the Bluetooth protocol supported on the windows platform now?

I got this message when I run the Chat bluetooth example:

qt.bluetooth: Dummy backend running. Qt Bluetooth module is non-functional.

Cannot bind chat server to "00:00:00:00:00:00"

Can anyone help me? Thanks in advance.

Best Regards.

Qt 4.6.0 ?

hi @Julian
you‘ll need to use MSVC compiler & Qt version

QtBluetooth is currently not supported on windows using mingw

@SGaist 4.6.0 refers most likly to the QtCreator version 😔

@J.Hilk said in Qt Bluetooth module is non-functional:

Thanks, It works with MSVC compiler.

Only for curiosity. Why does it work with MSVC and not with Mingw? Since a C ++ compiler links libraries and carries out an executable code from source code and the definitions of the variables, macros and structures as well as the functions and services (or daemons) are defined in the system libraries.

taken directly from the docu (first paragraph in fact ;-) ):

https://doc.qt.io/qt-5.11/qtbluetooth-index.html

afaik mingw does not support WinRT and it's apis.
