How to Programm the GPS?

[meer]

Hello,
does anybody know how to programm the GPS Modul?
I tried to change GGA to 1.
Can somebody help me?

www.franson.com They sell a module which you can easily program to with visual basic. They demo programs work without a modification. With Visual Studio you can start programming in a hour or so, after having had a look at the samples.

I think meer wants to adjust the SIRF-III-Chipset, which is used in the Orbit.

Most tools "Sirfdemo" etc. wont work on the Orbit. :-(

I'm searching for a tool which can toggle SN (Static Navigation) off on this device.

Hi,

I tried almost everything to program the internal GPS receiver of my P3300, but did not succeed :-(

First, I tried to get direct access to the hardware GPS port (COM 3), but failed to open this by any way. Eventually, I even sent my device into the Boot-Loader mode, redirected the GPS receiver to the USB port by using the GPSRouting command and connected via USB the SirfDemo 3.81 program. Results were very strange:


Using GPSRouting without a parameter gave me binary output data which SirfDemo was not able to handle.
Starting the the receiver at 57600 baud (by using the command "GPSRouting 57600" gave me NMEA output, which SirfDemo was partly able to handle. Some messages appeared correctly in the debug window, but most output of the GPS receiver resulted in SirfDemo in error messages. Really stranges!
I DID NOT FIND ANY WAY TO SWITCH TO SIRF MODE, which is necessary to program the internal sirfIII chipset.


I finally gave up and hope that one day HTC will surprise us with a nice tool to enable/disable Static Navigation and SBAS mode.

Have you tried using COM4 which is where the actual GPS receiver can be found? - Mike

Of course, trying to use COM4 was my first attempt.
However, COM4 is the output port of the MS GPS Intermediate Driver (GID). This is a software com port, which seems to be not the best implementation of a virtual comport splitter. There are a couple of programs out there, which have serious problems with the GID port, but do work with other (better) virtual comport splitter such as GPSGate.
Anyway, trying to program the internal GPS via the GID port did not work at all. That's why I was next trying to get direct access to the hardware GPS port (COM3), which did not work either, before I bravely sent my device into boot loader mode (unfortunately with also no success)...

Any other hints or suggestion are still highly appreciated.

do we have to give up any hope !? :'(

Please read my thread (http://forum.xda-developers.com/showthread.php?t=307004)

Explains it, i could post some code to get you up and running, but what language are u working?

but what language are u working?

thanks but just trying right now to understand how to get rid of this infamous GPSID ! ;)

Anyone knows how to turn off static navigation now? A programmer gave me a tool which perhaps can turn off static navigation on the p3300. But I'm afraid of testing it.

are you talking about spGPSView ?!

[Minipli]

The name of the tool is SirfTech. What about spGPSview? Can you disable SN with it?

[kulbut0r]

Can you disable SN with it?

Yes, Moreover, this prog. seems to be more "accessible" than SirfTech ! :)

[Minipli]

Are you serious? You can really disable static navigation on htc p3300 (artemis) with spGPSview? I often read that it wouldn't be possible....

the question should be : is it effective or not ? but it can be changed !:)

What port do you set?

[kulbut0r]

What port do you set?

com4 but the gpsid implementation of Orange is different from the HTC one as they are selling the M650 with their own navigation soft... :)

[Ward]

I have an XDA Orbit, so...

I've had no luck connecting to the GPS hardware with or without the MS Software splitter. Although other applications such as Beeline and iGo work fine.

[Minipli]

spGPSview doesn't work with htc p3300/ xda orbit ....

:(

Ah well. Thanks anyway.
