The GPS does not output NMEA data, but rather MEIF, a Nokia propietary protocol.

You can create NMEA data out of the Qt Mobility location information, though. It's trivial to write. There are several applications on the store (I suppose) which do this in order to emulate a "Bluetooth GPS" device.

I have written such a program at least three different times (e.g. http://javispedro.com/blog/2012/03/s...-the-same.html ). Data from Qt Mobility is not very filtered, as you can see on the figure (N9 is green line), so it is actually somewhat useful.
