Alltel GPS with A-GPS - super fast lockon

[jtcrusader]

To even get my GPS to function on the Alltel Touch (with the 6.1 upgrade)...I had to:
Set the GPS for Port 4 with a 4800 baud rate
Apply the fix from page one of this thread.

The GPS would not even register with LiveSearch or Google Maps before applying the fixes. Thanks!

Just reporting the results of doing this on my Sprint Mogul.

It seems like I do get faster lock after doing this and also locks on to more pilots and or satellites. For example I had 11 outside with clear skies, previously I would get about 8 max. While increase in satellites improves accuracy, I have not observed any increase in sensitivity. I still cannot get a lock inside my office.

Thanks for writing up the tutorial, cabs and links.

i took that sitting in my car, after driving to work with it on, and I'm parked up on the top floor of a 3 story building facing south, i can't get a lock, i feel like i've done everything including hard reseting 50 times, this is the best I can do

Location setting, *228 options 2 and 3. Check those!

ran up stairs and tried that, I usually do the *228 once a month, but even with reactivating, still no lock, I"m going to start over with the 6.1 and go as slow as I can

ok redid the 6.1 flash, first thing I did was the *228 option 2, reset, option 3, reset, then in the middle of syncing with exchange, it reset itself the same way it does after those two types of *228 options, I went looking at the localization setting, sure enough it was off, but I noticed the alltel navy icon was in my program list, is there something I have to do with that icon?

I fired up gps view, just to see if the gps was active, and it found it on com4, and it was parsing like it should, i haven't gone any further, i'm gonna slap latest googlemaps on there now.


just tried it, no lock, did qpstthing it was missing the ip of course, and port, set those, unchecked, rechecked, reset, ran reg, reset, opened up gps view, doing the same thing

first second, shows two or 3 sats, next shows none, next shows 13 sats or so, next none, then, then it starts over, none of them getting above the 30's on levels, just like the pic I posted on the bottom of the previous page

the alltel nav is just their navigation software that they charge 10$ a month for. u dont wanna use that. it might be that program ur using, just use google maps to test ur gps. make sure ur wifi card is off. make sure ur outside. make sure that u clicked 'write to phone' after u enter the settings in qpst. then reset the phone. 6.1 comes gps enabled so all that u need to do is the qpst agps fix. heres how to test if u agps is working:

open google maps, let it load the map data. then disable ur data connection in the comm manager. go back to google maps. click 'use gps' and see if your phone attempts a data connection. it should do it immediately after clicking 'use gps' in google maps. thats because it needs a data connection to get the agps data. if all goes well with that test, then ur problem is satellite visibility. nothing can fix that really. but if ur agps isnt working that can be addressed.

Worked awesome for me! Get an average lock on of 30 secs. Used to take an average of about 5 mins. Gonna try this on the wife's touch. Running Garmin Mobile XT and works great!

i updated the 1st post. the alltel windows mobile 6.1 rom cleared out my AGPS PDE server and pde port settings in qpst. you WILL need to repeat the agps fix after you flash the WM6.1 ROM.

I never let the customization run with the 6.1 ROM. so i dont believe telenav or anything else in the extended rom causes this. it is something in the system rom that causes the settings to be erased.

i have been looking for a way to apply the settings in qpst without having to use qpst. i agree that if a rom flash can erase these settings there must be a way to get the settings ENTERED either thru a flash or a cab.

Thanks for the tutorial and the files. It made the GPS work like I always thought it should.
