Are the GPS settings hard-coded in these ROMs?

[popdog54]

I was getting slow connect times with the internal GPS, around 3-4 minutes. I messed something up on my Mogul and had to do a hard reset. Since then the connect times have been about 10 seconds. I can't explain why but I'm not complaining. So, maybe a hard reset will help you.

Why would a hard reset be any different than the *multiple* times I have tried different ROM versions (5054, 5060, 5067, etc.) ?

i wonder if there is some kind inherent quality inconsistency in the radios on HTC phones. I previously had a Vogue and I got 5 second fixes upon a cold boot from both Tomtom with AstroGPSLauncher and Google Maps, but many people using the same ROMs would tell me about having serious difficulties.

Now I have a Titan/Mogul. The same deal, GPS worked like a charm as soon as i loaded the Titan Radio from the Sprint factory ROM.

Sorry this isn't more helpful, but maybe compare your phone to a friend's?

I am not interested in getting the internal GPS to work. I already have it working, provided it can get a signal... it just doesn't work as well as the external GPS receiver that I have. The external device is more accurate and faster to update.

Why am I unable to change the settings using the "External GPS" icon, even if I flash with a "No GPS" ROM?

I perform a hard reset after any reflash.

From my experience, the settings in "External GPS" really only apply to the internal GPS and configure a port that emulates an external GPS.

I can switch back and forth between the internal and external Bluetooth GPS on my Mogul just by selecting different ports in my application. If your application does not allow you to manually select the port, try disabling the "Manage GPS Automatically" check-box in "External GPS", and configure your Bluetooth GPS to use a COM port such as COM5, and see if the application will find it.

If you have not already done so, after you pair the Bluetooth GPS receiver, go to the "COM Ports" tab and create a "New Outgoing Port" for that device.

I have successfully used the "External GPS" icon to configure an external GPS (go figure! ) on my XV6700 with no problems at all.

Try doing that with a program that doesn't have its own GPS configuration and *depends* on the Windows settings...

greatest... answer... ever... period lol

Have you checked to see if that HTC guardian or whatever is running and changing stuff back? I've never done it but I know people have to remove that to change DNS servers and such to keep them from getting switched back - maybe it is changing the GPS settings - just a thought...

I had the same issues with my GPS when I first started to get my internal GPS to work. It would take forever to connect and only connect to a few satelites when it finally did. I used the stock sprint roms, but always stopped the customizations from running by doing a soft reset when the window comes up that says it's about to install customizations.

I have no idea what thread it was in now, but someone finally explained the source of this issue. In the sprint customizations, one of the installs runs a microcode patch. This fixes the internal gps issues. The best part of it is it's a permanant fix. Immediately after the customizations finishes, do another hard reset and stop the cusomizations from running. You don't need to run the microcode fixes ever again, despite any hard resets.


A note for people running stock roms on sprint, and avoiding the sprint customizations. In my experience, the IOTA.cab file in the extended rom needs to be run for data services to work correctly.
