Hi,

this is very interesting. I wanted to start a thread about not getting
position data, when I saw this thread....

My (not always reproducible) experience so far on Nokia C7 with Qt 4.7.2
and QtM 1.1.1:

Indoor WLAN and GSM:
- Running my app alone, I don't get any position updates at all.
- Ovi Maps gets a position just fine.
- Running Ovi Maps and my app in parallel I can get at least some data
when calling lastKnownPosition().
- After disabling the "Wi-Fi/Network" positioning method I get position
updates.

Outdoor GSM:
- It looks like if I have a GPS fix, I also get position updates. But
I'm not completely sure about that yet.

Also it looks like the Symbian implementation differs from the Maemo5
implementation. On Maemo5, if I do setUpdateInterval(1000), I'll get a
signal every second whether or not the position has actually changed. On
Symbian it looks to me that I only get a signal if the position really
has changed.

Cheers,
Conny
