Are the GPS settings hard-coded in these ROMs?
 

I have been trying, without success, to configure my external bluetooth GPS. Why? Well, because it works MUCH better than the internal GPS on my phone.

The problem is that the settings in "External GPS" on the "Hardware" tab will not accept any changes. No matter what I try setting them to, they always revert back to COM4 and Baud rate = (None).

I have tried selecting "GPS" and "no GPS" when building a ROM in the kitchen. I have also tried 5060 and 5067 ROMs.


Is this stuff hard-coded into the ROMs? If so, WHY? I should be able to configure my phone to use an external GPS even if I have cooked a ROM that enables the internal GPS.

I basically asked this same question when the first GPS ROM was leaked and got no responses. I too wanted to use my external bluetooth GPS, but like you couldn't change the settings. And I still haven't been able to. I've looked for a registry entry, searched online, etc., to no avail.

Re: Are the GPS settings hard-coded in these ROMs?
 

Only thing I can think of would be to try an untouched stock rom, and see what happens. if it works great, if not, sorry for wasting your time

edit: I wonder if no2chem changed the external gps proggy to only read the registry, not to write changes to it, find the entries in the registry and you might be a winner. but then again, this one aint easy to track down in the registry

If you are thinking your bluetooth gps is superior, your gps is probably misconfigured. While I can't speak 100% about verizon (I don't know for sure if the gps will work in AGPS mode on verizon), if you're on sprint and getting better performance from a bluetooth gps, something is WRONG.

I had my gps for a long time unable to get locks even in my car without holding it up to the window, etc. My friend would tell me all the time how his connected very quickly with 8-9 sats indoors. I thought it was something weird and just maybe with his location or something. My bluetooth worked wayyyy better. He had the commercial sprint gps rom and let customizations run (I don't think I let customizations run before I installed a hacked rom).

However, after flashing the beta rom, letting sprint customizations run, my gps was consistently getting a lock within 5 seconds indoors in my house where I can barely get my bluetooth gps to connect (and could never get my phone's to connect). I have since installed nuerom 5060 and am still getting this kind of performance. A complete and total 180 on the gps performance.

It works amazing, wayyyyyy better than my bluetooth gps (and I have a nice SiRF III bluetooth gps, not a cheapie crappy one). I get locks in under 5 seconds in all instances, indoors, outdoors, in my car, etc. It is amazing. While I don't try it in highrise buildings, trust me, people are NOT exaggerating the performance of the internal gps. It is 10x better than any external gps when set up properly due to the fact that it can connect to an assistance server for help locking.

On another note, if you reallllly do want your bluetooth gps working, don't mess with the external gps settings, just set the com port manually in google maps or whatever to the actual com port you are assigning in the bluetooth connection to the gps receiver. That's what I did before I figured out that the internal gps could really be so powerful.

How could I possibly misconfigure it? There's nothing to configure, since the settings are hard-coded... even in a non-GPS ROM!

The internal GPS does work, but it is MUCH slower to update and lock than my external, and it's nowhere near as precise. My external GPS is so incredibly accurate, I am amazed... easily within 6ft on a satellite view... it will correctly show what lane I am in on the highway!


Now try doing that with a program that does not have it's own GPS configuration and relies on the settings made from the "External GPS" icon.

Re: Are the GPS settings hard-coded in these ROMs?
 

Read my post, I had that problem for a really long time, then finally got my gps working. I have had 5 second locks for a few weeks now, and use my gps daily now that it works correctly. Once you get it working properly it is amazing...

Re: Are the GPS settings hard-coded in these ROMs?
 

What should/could I be doing differently to make the internal GPS work better... other than upgrading the radio and flashing the latest ROM?

I *can't* let the Sprint customizations run, as I use Verizon.

Re: Are the GPS settings hard-coded in these ROMs?
 

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.

Re: Are the GPS settings hard-coded in these ROMs?
 

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

because sometimes **** just starts working for no apparent reason

Re: Are the GPS settings hard-coded in these ROMs?
 

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?

Re: Are the GPS settings hard-coded in these ROMs?
 

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.

Re: Are the GPS settings hard-coded in these ROMs?
 

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.

Re: Are the GPS settings hard-coded in these ROMs?
 

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...

Re: Are the GPS settings hard-coded in these ROMs?
 

I feel your pain. I eventually gave up. But as I said in my previous post, after a did a hard reset the internal GPS was much, much better, so I'm not complaining anymore.

I know you said you've reflashed your phone numerous times, but did you try installing the stock ROM then do a hard reset? I have no explanation why my GPS improved, but it's worth a shot.

Re: Are the GPS settings hard-coded in these ROMs?
 

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...

Re: Are the GPS settings hard-coded in these ROMs?
 

Actually, I was suggesting that YOU try doing that; possibly your application will find the external GPS if the internal one is turned off. Since you are keeping any details of the subject application secret, no one else can try it or offer any experiences they may have had with that same application.

I have the Sprint Mogul, and running the stock OEM 3.35 ROM, can set the parameters in that External GPS screen and they stick. You aren't doing something like pressing OK to exit and "save" the changes when you have Task Manager set to close apps with a tap?

Re: Are the GPS settings hard-coded in these ROMs?
 

I've never heard of HTC Guardian, so I'm certain I don't have it loaded.


LOL... I'm not keeping any secrets. One example of an application that relies on the Windows settings is GPS Today.

You know WHY you can change the settings? ...because you're running the stock OEM ROM. ;)

I am using WkTask, but I have it set to NOT close automatically (tap action set to "do nothing"). If I want to close the app, I have to tap and hold for the menu, then choose "close".

Re: Are the GPS settings hard-coded in these ROMs?
 

My internal GPS does this. It can even show what quadrant of my deck I am on when using Live Search.

Re: Are the GPS settings hard-coded in these ROMs?
 

Color me jealous. If mine worked that well, I wouldn't be asking these questions. ;)


The overall point is... these settings should not be hard-coded, even if the internal GPS is supposed to work perfectly fine.

Re: Are the GPS settings hard-coded in these ROMs?
 

Apparently, HTC did not hard-code them, as the OEM ROM does not do it. Have you tried, just to see if it works, loading the Sprint OEM ROM package, not letting the customizations run of course, and then attempting to set up your external GPS in a way that works for GPS Today?

You also might try asking about the problem in the thread for the custom ROMs you are using.

Re: Are the GPS settings hard-coded in these ROMs?
 

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.

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

Re: Are the GPS settings hard-coded in these ROMs?
 

Sorry to revive a dead thread, but it seemed better than starting a new one...

I recently got a warranty replacement Titan from Sprint. The internal GPS will stop working sometimes after a few hours, sometimes after a few days. The only fix I've found is to reinstall the OEM 3.56 stock ROM from scratch, then everything is fine again.

Has anyone else experienced anything like this? Does anyone know of a fix?

Thanks!
