ExtGPS couldn't detect the satellites on N9 while the Symbian version on my old 5230 gets a fix at the same time.

After Bluetooth pairing between N9 and 5230, did N9 Settings -> Device: use external GPS - found 5230 OK.
- ExtGPS on N9 still fails (Bluetooth connection established OK, 5230 has got a GPS fix)
- gpsmeefo, N9 car navigator, none of them works, either with internal or external GPS.

Only thing I get is a crappy GSM estimation on Nokia Maps, either from supl.nokia.com or supl.google.com, which I have set alternatively in /etc/xdg/nokia/location-settings.conf
- gpsmeefo shows a few satellites with internal GPS activated again, but does not get a GPS fix.

Anybody out there with the same problem, can this be a hardware problem since a few satellites are seen by gpsmeefo?

And/or is there anybody having successfully used an external GPS device over Bluetooth, what ever model? (using 5230 would not bother me if I have got a hardware problem). Thanks !
