Re: GPS Performance

To clear this up once and for all I did some experimenting - via getting the gps to work and attempting to break it.

In TOMTOM while gps functioning...
I've found that during times of low memory if you push power off button -wait a few seconds- slide2unlock- then the gps loses signal and you will just have to restart the app.

However, If (in TOMTOM gps config) it shows no bars and the wheel is not spinning you will at a minimum have to soft reset the phone.

If necessary, I've found in all circumstances that taking the battery out and putting it back in would allow the gps to work again. (provided you aren't using too much resources when you run it again)

I've experimented on both my Mogul and my Touch and it appears to be the same.

Re: GPS Performance

I think that aGPS might be screwing a little the GPS part.

At times, even though I'm connected to 6 satellites on google maps,it just starts to stray away. Google maps would be showing me going in the wrong direction for about 20-30 seconds and then actually come back to it's proper location.
Maybe it's google maps sucking / crap, but besides those couple of instances, I found it to be really good.

I want to try something else, but don't want to pay for it :S

Re: GPS Performance

In the reg, not sure of the keys do a search, set the gps id to 4 and use JD's test rom 2. GPS locks in less than 10secs outside and less than 1 min inside. Telenav works flawlessly. It's sweet when your plan includes telenav free! Get the unlimited plan or your driving your convertable with the top up!

Re: GPS Performance

It's HKEY_LOCAL_MACHINE\SOftware\HTC\SUPL AGPS

The GPSMode setting can be changed to 1 for GPS (Satellite) Only, 2 for GPS/AGPS (I think), and then 4 for some kind of hybrid mode.. I've found 4 works best.

JD had 2 attempts at the his GPS Rom. 99% of the links to his rom is the second attempt. The first one was missing some files or something to get the GPS working.

Re: GPS Performance

I don't get nearly as far as any of you guys.. i'm runnin JD's rom, can run gps viewer and it find the gps device on com 4. hit open and it finds sat's but all of them are over the N on the little globe and it will find about 12 but no LAT or LAN and all..... i'm so frustrated " and sorry for the run on i'm just so pissed

there is one "nasty" issue i'm experiencing with Garmin Mobile XT and the Sprint Touch: everytime i launch Garmin, it resets my clock and date to 7 pm and 4/19/2008, respectively. as long as Garmin is loaded, manually changing the time/date has no effect on the clock. now, once i get satellite locks, the clock will update (i'll have to check the settings to see if i can disable this feature).

maybe GPS on the Touch is not ready for prime time - which may account for the delayed release to the general Touch public. nonetheless, i'll continue to play with GPS until the "official" version surfaces. all of my other phone features are working without issue. in case anyone is interested, i'm using JD's 6.1 ROM.

Damn it!!!!! ME TOO! When I launch Mobile XT, the damn clock rolls back to 4/19/2008, however mine time was set to 5pm!!!

What gives?!

I stayed outside under a clear sky (in a park) for about 20 minutes yesterday trying to get a fix - never got it...

i'm experiencing issues making and receiving calls as well as a few 10-30 second "freeze" episodes so i bailed out: i'm going back to the stock Sprint Radio and a WM 6.1 ROM until Sprint releases the official upgrade. i have a Blackjack II and Orbit 2 with GPS so i'll use those for navigation when needed...

Re: GPS Performance

I got frustrated because I kept trying to get locks, but couldn't. Then I left it on and went to sleep. When I woke up, bam 4 locks.

Now it only takes like a few seconds to lock, and google maps is working perfectly. Well, it worked perfectly until I soft reset my phone, then I had to try for 20 minutes to get a lock afterwards. But after getting that initial lock, everything is working fine again.
