Hi,

I use smartphone QTEK 8130 with bluetooth GPS device and want to read GPS
position with C#.
At the moment there is no managed API with the smartphone SDK.
There exists the GPS Intermediate Driver, I tried:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/mobilesdk5/html/wce51congpsintermediatedriverplugplayregistrysettings.asp

I added all needed registry settings under HKLM
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/mobilesdk5/html/wce51congpsintermediatedriverplugplayregistrysettings.asp)

But I get no respond from gps device. Could someone give me more information?

I found an GPS example in Windows Mobile 5.0 Pocket PC SDK but not in the
Windows Mobile 5.0 Smartphone SDK. I convert the sample from PPC to SP it
runs but it doesnt work.

I ask me if it is not possible to use GPS Intermediate Driver with my
smartphone...?!?

Best regards
Christoph

You need to map your GPS device to a COM port and then configure GPSID to
read GPS data from that COM port before using the GPSID APIs. Please refer to
MSDN documentation on GPSID for further details.

I mapped my GPS device to COM7: and added the needed information to registry.
But it still not work.
I read the MSDN docu in all directions (I think ;) but at the moment I think
that there is a problem between my SP, bluetooth device and GPSID.

I've heard that this problem is traced back to a problem with the Microsoft
Bluetooth SPP (Serial Port Profile) implementation in the BT stack. I've had
exactly the same results, only on SmartPhone, and apparently you can get
around it by implementing your own SPP profile using lower level sockets and
BT. Royal pain in the arse.

I haven't implemented such a thing. If you find out if someone has, or if MS
have gotten their act together and provided a FIX, I'd appreciate it.
