    According to the new Qt learning material

    There is new Qt Mobile learning material available on the page :
    http://www.forum.nokia.com/Library/Learning/Qt.xhtml

    found from "Qt for Mobile Application Development for Education v1.1" link.

    (
    By the way, after unzipping new learning material, you need at least Power Point Viewer to
    see the new learning material.
    )

    But my question concers about "On Device Debugging via Bluetooth as the new learning material mentions.

    In the folder of "2 Qt for Symbian" of "Qt for Symbian_Slides v1.1.pptx"
    slide 49 of 90 mentions that : "Communication between Nokia Qt SDK and App TRK can be done
    by using USB or Bt" and slide is shown here :



    So, is "communication" between App TRK and QtCreator via Bt (==Bluetooth?) possible when
    i want to on device debug Qt application running on my E71 phone (=S60 3rd ed. fp1 device).

    Yes, i know that it is possible to on-device debug application running on my phone
    via usb "cable", but is on device debugging possible also via Bluetooth, as new learning
    material mentions? Or is it a bug in the new learning material when mentioning the Bt-possibility
    to on device debug application running on the phone.

    BT debugging has always been a rumor, but I never got it to work (and gave up trying, since there's really no big advantage to it).

    but my debugging environment is presented here :



    It is not very nice to debug on your knees !

    Just waiting the Bt-debugging environment at least in my dreams.

    Yes, but there is limitation for the length for the usb cable - i think so.
    Length from my computer's bt-connector from the floor to my table and on the phone
    on my hands, is about 2 meters (do not know how
    many US-inches is 2 european meters).

    But any way, do you think, that 2 meters (meter in european meters) is not too far
    away from the computers bt connector to reach to my phone on my table and on
    my hands, when computer is lying on the floor, and too far away from the phone.....

    The standard cable that comes with the phone is maybe a half-meter long. You should be able to find an extension USB cable (or two) for an extra meter or two. A quick Google suggests that USB standards allow an 5-meter cable.

    Yes, seems that USB connections are able to work with up to 5 meter cable's length :

    http://en.wikipedia.org/wiki/Universal_Serial_Bus

    But i do not want to go in the details, that how impedances with device, cable and
    computer connectors has to be adjusted with each others (in electrical ways).

    For example, if cable's impedance between device and computer connection are
    not adjusted well, then the data traffic will be distortioned a quite well.

    But sure i can try the cable extenders and see in practice, how that works.
