    Hello,
    I'm new in Qt, and I want to develop a program with BLE connection. I started to run "Bluetooth Low Energy Scanner" example and some other examples from the examples list. But it doesn't work correctly. The list of devices always empty.
    I am using windows 10 and Qt 5.10.0
    Can anyone help me please?

      nmake install in the build folder if you are using Visual Studio and mingw32-make install if you are using MinGW

            As the error suggests: you are missing Perl. Install it.

            It’s normal noting changed, the module wasn’t even built.

              @SGaist During installation process of QT this problem occurred:

              0_1514874723242_Qt-perl.png
              So I clicked 'Ignore'.
              Then I tried to install "C:\Qt\Qt5.10.0\Tools\Perl52213_32\strawberry-perl-5.22.1.3-32bit.msi
              but nothing changed.
              I tried to reinstall it and disabled Antivirus and the same error appeared.
              Is there anyway to overcome this problem?

                Did it install successfully ?
                If so did you try to call perl from a new command prompt ?

                    @Ashi Shouldn't you "nmake install" what you cloned from the repository before?

                    git clone git://code.qt.io/qt/qtconnectivity.git
                    cd qtconnectivity
                    git checkout wip/win
                    ...
                    nmake
                    nmake install

                      You should also use the correct command line prompt for building especially if you start with the one provided by Visual Studio.

                        @Ashi Sorry, I'm too late to answer this post. I think you should try with msvc compiler, not mingw
