Need clarifications concerning GPS access via the HTML5 API, or an external sensor

    Question

  • Hi,

    I have an maps app in store and many user complain that it doesn't grab their GPS position, even tho their tablets have a GPS integrated.

    To grab the user's position, I used the HTML5 Geolocation API (navigator.geolocation). Is this one only catching network geolocation and not sensors ? Should i use the Geolocation API from WinJS instead to get better results, including results from embedded GPS sensors? This is the API I am not using at the moment: Windows.Devices.Geolocation

    http://code.msdn.microsoft.com/windowsapps/Geolocation-2483de66

    Also, some users have external Bluetooth GPS that communicate via the COM port (say COM 4). Can I access the informations from these sensors ? I read online that it would also be seen as a USB devices and that thanks to the Windows 8.1 new USB APIs, I would be able to grab the data from this device. Is that possible, and is there any ressource about this techniques?

    Thanks a lot for your help,

    Fabien
