          Hi,

          I posted on this topic yesterday in the lounge so I will jump in on this thread.

          So does anyone have any working C++ code on Qt using the windows Bluetooth API? https://msdn.microsoft.com/en-us/library/windows/apps/windows.devices.bluetooth.aspx

          A simple scanner program would probably be enough to get started.

            @Chris-Kawa Hi Chris.I am developing on windows QT. My application will be deployed on any android device. Currently i have written code too search and display all available Bluetooth devices in range. once after selecting the device i am able to pair but i am not able to connect to other(remote) device.

            My device Bluetooth is turning off immediately and a pop up appears saying do you want to switch on Bluetooth. after allowing the same , my application crashes.

            QT examples are also not working.

              @Dr_Firmware Hello Dr_Firmware, Thank you for replying. If i use windows api then i doubt if this will work on any android device after deploying. So i was in search of working code in qt and i will deploy it on android device and test the application.

              Can you provide any information on this ?

              Thank you very much.

                @RohitIti Hi, so I guess I misunderstood you. So you want to develop an android app that uses bluetooth. This should be doable. Although I have no idea how to do it at the moment. I just got qt 5.5 working and created a "hello android" app and simulated on Nexus S AVD. So things are looking up but this is a whole new world for me. If I get anywhere with this I will let you know.

                Regards,

                Chris
