Like Erel said, you need to connect the driver to it.

Start->Settings->System->External GPS->Hardware->GPS hardware port

The COM port you need is the outbound COM port of the virtual Serial Port on your Bluetooth Serial Port service. How you find this depends upon the software the device manufacturer provided to access Bluetooth on your device.

No matter what COM port I put GPS Hardware port to it always resets itself to none, is there a fix for that.

I also tried running the GPSDriver demo on an old hp iPAQ h2200 (Windows CE 4.20) without an internal GPS receiver. It complained about not finding 'gpsapi.dll'. Am i correct in stating that devices without internal GPS must use the previous gps.dll?

[Erel]

The GPSDriver is only supported by Windows Mobile 5.0 and newer devices.

I'm using GPS Driver with a Touch Diamond without problems. I changed the ROM of my P3300 and works ok, but I'm trying to run my app. with a HTC Touch Cruise and I have an error:

Error getting device state.
Error number: 4319
Continue?

It has the newest ROM installed and so on. I don't know what's happening.

Thanks in advance.

I think I've discovered why it fails.

I have updated the 'Quick GPS' app. for first time. Once connected, GPS Driver error has dissapeared and application works fine.

[agraham]

That's interesting! By "updated" I assume you mean you allowed Quick GPS to connect and download new data, not that you "updated" to a different version of the app.

[2220]

Yes, Update positioning with Quick GPS.

I'm trying again with another new PPC, but I'm afraid this is the answer to all my headaches.

Since I am working on a version of GPS4PPC for marine navigation I thought I should look at the MagneticVariation property of Gpsdriver.

My ancient Garmin GPS-II+ returns 4.2 whereas my slightly younger yellow Etrex gives 2.8. (The built-in Sirf chip in my PPC PDA does not offer MagneticVariation.)

But I believe that MagneticVariation for the UK should be westerly which by the usual convention (and that stated for Gpsdriver) should be negative for westerly.

Does anyone see a negative value for MagneticVariation from their GPS in the UK?

Yes, I just have! It would be nice if there were a note about that in the Help (instead of the implication that only a few restricted Format() layouts will work).

If the complete repertoire is extensive I would be happy with a link to the .NET full definition (if that is where it emanates from).

For standard and custom numeric formatting with Format()

Numeric Format Strings

Note that "x" does not work because numbers are Doubles in Basic4ppc and "x" takes integers. Also note that Basic4ppc converts the format string to lower case.


For standard and custom numeric date and time formatting with DateFormat() and TimeFormat()

Date and Time Format Strings

Note that DateFormat replaces "m" with "M". TimeFormat replaces "M" with "m", "S" with "s" and "T" with "t". Date and Time are identical functions but just use the different format strings so they are actually both DateTime format functions but using the slightly differently modified format strings.
