GPS Lock Times

I know there are MANY threads to the GPS issues and I am not having problems with GPS lag. I have searched and read and already have the tweaks installed (running the Elite rom rc2 which already had all the tweaks setup) and changed the no data sleep timeout to 1.5 seconds. I also tried on my original radio version, 32 and now have 28 and see no difference in GPS lock times. It will never lock on using Google Maps or iGuidance. In google Maps it says "seeking gps satellites (0)..." for about 5 min then says your gps receiver is having trouble tracking satellites etc. The only way I can get it to work is to use GPS Test, let it get a lock which usually take 5-10 mins, then close GPS Test and open either Google Maps or iGuidance and it will then work fine.
What is also strange is that when using GPS Test, the only way I can get it to work is to have the GPS info set to auto. It will scan then find the gps on com port 4 and 9600 baud. Then it will start up and try to lock on. The next time I run it it will already be on com port 4 and 9600 baud but won't find the gps device. I have to set it back to auto, and restart GPS Test, then it finds it.
There has GOT to be a way to fix the gps lock time on this thing. I have tried with A-GPS on and off and tried with quick-gps and saw no difference in lock speeds. Interesting thing though, I guess Google Maps will using cell tower location to identify where you are? When I use it without gps being turned on, or while it is searching for satellites, and I click "my location" it gets a fairly accurate location on the map.
It seems to me that the issue is with the com port and communication. Almost like the gps won't come out of sleep mode or something and gps test is the only program that can "wake" it.
Thanks for any info.

I am in the exact same situation as you. My TP fails to lock satelites 98% of the times i try.
I have read everything posted about TP GPS on this forum, i have tryed most ROM's and almost all available radio's, i have tryed most tweeks and all that in different set-up.
And after all that my GPS lock's rarely (2-5% of the times i try), and most importantly it doesent seem to be related to the radio nor to the ROM. At this moment i tend to think that i was unlucky with my TP that perhaps is from a lot of TP's with retarded GPS module.
From the forums it seems that most of the ppl dont experience this extrem problem with the GPS, it seems that most of the ppl around only experience laggy gps module update.
Atm i am still waiting for Elite RC3 hopeing that perhaps they'll bring a new gps driver, that will solve my problem.
In case Elite RC3 doesent help i will revert to stock hard-spl/radio/ROM and ill take it to the warranty service.
Sadly this problem with the GPS from my TP blackens my experience with it.

Are you guys sitting in your homes trying to get a lock? because then it is very unlikely you'll ever get a lock.
I have to go outside and wait about 1 minute to get a lock and then its fine. However, I DO have to use the HTC gps tool to get a lock before I can use google maps or any other gps program.

I am outside with no obstructions. I did find this app and may play around with it. So far I havne't been able to get it to get a lock unless I use GPS Test first.

My Telus Touch Pro locks in 3-5 seconds every time after modifying the GPS and adding the correct IP settings for Telus' AGPS. This combined with OCN8 makes for an excellent GPS device.
The guide for the GPS hack was from this forum, just can't recall where.

I have the same problem with GPS Test as you all described. I am now running qsqa's PROven ROM and I noticed following: GPS Test often fails to start-up the GPS receiver, but VisualGPSce worked every time I tried. It is a free software, included in the PROven ROM. If u use a different ROM, you can download it from here: http://www.visualgps.net/VisualGPSce/default.htm
Give it a try, it sure helped me!!!!

how to test GPS ?

After updated to android CM7 2.3.4, I found the GPS not work, but I'm not sure the problem is the GPS modul, who can tell me how to test the GPS is ok or not ?

There is an app in the market called GPS Status & Toolbox which gives you info about your GPS and sensor data: position and signal strength of satellites, accuracy, speed, acceleration, bearing.
It also let's you reset your GPS if I remember correctly.
GPS Status & Toolbox

thanks a lot

Go to market and search "GPS", you'll find many GPS testing apps.

[Q] GPS: About 12 satellites in view but no lock/fix?

I have a 'GooApple V5 3G':
http://www.gooappleblog.com/gooapple-v5-3g-review/
The phone works fine except don't know how to get the GPS to work.
'GPS Test' says about 12 satellites in view, but I never get any '"lock/fix".
I'm in Sweden (if it matters) and users with the same phone-model from other countries Europe and US seems to have no big problems getting their GPS to fix (though they may be a bit more tech-savvy).
Any suggestions on how I can make my GPS lock/fix?

[Q] GPS works... except in other apps

I applied the new baseband and I get instant GPS locks when using Maps or GPS Status. However, when I try running apps, like MapMyRun or Cardiotrainer, they complain that they can't get a GPS lock. Does anyone have any ideas as to what might be causing this or what I could do to make these apps work as well as Maps and GPS Status?

Are you running on ICS? Make sure the app is compatible with ICS, because many aren't. Try google maps and test the gps

Make sure it's also toggled on in settings, and are you running a ROM?
Test Google maps, it should always work.
