    Hi,

    Check the bluez version you are having just to be sure it's minimum version corresponds to what Qt needs.

    Hope it helps

        After many days on compile Qt with dbus and bluetooth support the problem still exists.
        Have you found the solution? Is the case to open a bug report?

            My problem is solved. Is necessary to delete and recompile Qt if you install headers after a compilation.
            My Raspberry PI work great with Bluetooth.

              I had the same problem with Qt 5.3.2 static build.
              After recompiling, checking dbus, bluez version and looking qtconnectivity log files, I realized that you must have root permissions to run Bluetooth samples!
              Running my program with sudo solved the problem!

              Maybe this post can help someone.

                  Are you in bluethooth group?
                  If you are intwrested, I have build an io card for raspberry to manager input, relè and RFID readers.

                      Thanks mrdebug... this can be very interesting for future projects. You have more details?

                      We are currently working in an industrial raspberry module with these features:

                      • 24 VDC supply
                      • ION battery for backup
                      • Real time clock
                      • Optoisolated inputs (4).
                      • Relay outputs (4).
                      • Connector/supply for 4D systems LCDs
                      • Microcontroller connected to the I2C to act as RTC, power manager and system watchdog.

                      Please make know if you are interested

                          Ok. Is this device available online?
                          I'm waiting for 2 prototypes and, when the device will be ok I hope to have business with Raspberry - RFID - Qt.
                          If you are interested I will send to you documentation when the device will be available.
