Any suggestions on where to get started on reading GPS coordinates?
Would these be read through the serial interface? I have a Motorola Q9C
Smartphone.
One approach (if you don't mind being Windows Mobile dependant) is to use ctypes
to interface to the GPS Intermediate Driver (documented on MSDN at
http://msdn.microsoft.com/en-us/library/ms850332.aspx).
This approach would take care of NEMA sentance parsing etc and give you a
structure with current lat/long and speed etc.
Alternatively you can also go the serial port route. In that case you can use
the
GPS control panel applet to determine which COM port you should read from. See
http://blogs.conchango.com/kenibarwick/archive/2006/03/19/3119.aspx for more
details.
Hope this helps,

Thanks for the info. I think the serial approach would suit me better.
However... I don't think the GPS control panel exists on my phone (there
was no GPS Settings registry key). I wonder if MS removed it in WM 6.1.
Do you know if these settings can be specified manually?
Thanks!
Justin
