    Thanks @SGaist ,

    I tried to do the following:
    git clone git://code.qt.io/qt/qtconnectivity.git
    cd qtconnectivity
    git checkout wip/win

    But still the same problem. The devices list is empty.
    Did I do something wrong? or miss something?
    Thank you very much!

          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.

                              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?

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