Wanted: Share your *WORKING* GPS config

[licht77]

Hi folks!

I got those **** GPS problems with my TP and worked myself now several days through dozens of related threats. Unfortunately, there doesnt seem to be a "one-best-way" but several (even some contradicting) suggestions... - and no Wikipage so far

After playing now with a lot of suggestions (registry tweak, killing the logfiles, gpsgate / splitter, AstroGPSLauncher, some mortscripts, about 6 different RadioRoms and maybe all baudrates/config combos of 5 different navigation systems) i got now really stuck and kinda frustrated. (Read: Yes, i used the search function!) Maybe i should burn that device - OR - some of you share their GPS configs / fixes / history so that i / we can write together a comprehensive (hopefully leading to a working solution) wikipage

I would be highly interested in:

o Working solution yes or no?
o ROM & RadioROM
o Did u have GPS problems at all? Which ones? No Fix? Slow fix? inaccurate? Jumping around position / loosing the signal each and every second? Lags?
o Could you solve it?
o How?

I hope with some of those working configurations it should be possible to replicate a working device...

Thx in advance!

First feedback with working combinations (QuickGPS as standard not included):

#####################################################
ROMeOS 1.60.1 - Radio 1.02.25.28 - fix < 1min - no Tweaks
ROMeOS 1.51 GER - Radio 1.02.25.19 - fix <> 30sec - Portsplitter
Da_G v2.03-MSVC - Radio v1.02.25.28 - fix < 1min - (kickstart for TomTom)
NATF 3.2 ROM -1.08.25.20M1 - fix < 1 min - no Tweaks
ROMeOS² v1.60.2 - 1.08.25.20M1 - fix < 15 sek - QuickGPS disabled, PagePool 32MB
LantisOS Rom -.32 ATT Radio - fix < 1min
#####################################################

EDIT: If possible, please post your initial fix time using VisualGPSCE outside with a clear view of the sky (no kick starting allowed, just fire up VisualGPSCE and start a timer)? Set VisualGPSce to COM4: at 115200 bps (speed doesn't really matter as long as its >4800). : http://forum.xda-developers.com/showpost.php?p=3116607&postcount=7


Please share your config here: http://wiki.xda-developers.com/index.php?pagename=GPS Issues

Thanks to Sleuth for the standartisation hint!

Did you change your Navigating Software to the new ports of the comsplitter with the GPS Signal? I had the same secondly changing signal- no signal, but after installing comportsplitter and changing the settings of the Navigating sw to the new ports there is a constant strong signal there with no lag.... Using ROMeOS 1.51 Ger and Radio 1.02.25.19. I tried nearly all radios, but most of them cause a big battery leak (for my TP)

P.S. I have a fix in nearly 30 seconds, but only after clearing the gps cache with the htc tools. the first fix took about 45 Minutes, but now its at half a minute. I deactivatet agps as recommended in many threats in several forums, but i use quickGPS

 

[licht77]

Thx for your information! (Sure i changed to the new Comports *g*)

Using ROMeOS 1.60.1 and radio 1.02.25.28 i get a fix in under a minute, just by using QuickGPS included in the rom.

Same radio configuration with Da_G 2.03 (see sig). VisualGPSce can fix outside in < 1 minute. TomTom needed to be "kick started" by another pgm but could see the GPSID natively (gave the built-in gps option in device configuration). After omitting the Flags value=2 (GPSID driver is unloadable) in HKEY_LOCAL_MACHINE\Drivers\BuiltIn\GPSID then TomTom was able to warm start the GPS in < 1 minute as well without needing a "kick start".

Currently, TomTom updates the display 3-4 times/sec and has little if no lag (cross streets on map pass by at the same time as the car does at 40mph). The only thing I continue to suffer from is "speed lag" whereby TomTom doesn't track with the speedometer when I slow down to 0mph. This can result in the car display ending up in the intersection on the map when the car is stopped (then it "snaps back"). I'm going to see how TomTom 6.x deals with this so I can get an apples to apples comparison with my Tilt which didn't suffer from speed lag.

Could I suggest Standardizing our tests?

What's your initial fix time using VisualGPSCE outside with a clear view of the sky (no kick starting allowed, just fire up VisualGPSCE and start a timer)? Set VisualGPSce to COM4: at 115200 bps (speed doesn't really matter as long as its >4800).

The first time you get a fix on any given day should be the one you report as this will be the longest. The reason is that QuickGPS ephemeris data will be used which gives approximate satellite positions. Subsequent fixes (try it!) will be lightning quick because you will be using actual ephemeris data downloaded from the satellites which gives precise sky locations for the time duration that the birds remain visible.

I am using NATF 3.2 ROM and 1.08.25.20M1 Radio. I use OCN8 and it gets <1 minute fix. No changes done to comp port or baud rate. However, it takes tweaking got get fix for Google Maps in little over 1 minute. I do experience LAG on OCN8 though.

I used to use Elice RC2 and 1.08.25.20M1 ROM. LAG was very very minimal but took more time to fix.

Here's the installation cab for VisualGPSce btw. It's freeware.

Yep VGPSCE is a classic tool

I flashed this ROM and it works perfect for me.

 

[lepermessiah]

my config (signature) fixes up under 15 seconds when moving, <1minute when standing on one place. QuickGPS disabled, PagePool 32MB

For me prior to updating my ROM I could not get a GPS fix no matter what I did. Some of the newer ROMs use new GPS Drivers. This must have fixed my problem. I tried others older ROMS and no Fix, I tried a few Radios and no Fix.
I'm using LantisOS Rom, and the .32 ATT Radio. My GPS works with AGPS enabled or disabled, it doesn't matter.
I still have some lag, but its not too bad.

Here is what I do to get a fix.
1. I use QuickGPS to download the data.
2. I Launch Chartcross GPS Test to get a fix usually in under a minute if I havent used it for awhile. If I used it earlier in the day i can get a fix in like 5 seconds.
3. I either close or minimize GPS Test and launch my GPS program. (Google maps, Live Search, & iGuidance all work for me)

P.S. I do not use HTC GPS Tool as I've never got it to work. I have VisualGPSce which is good for viewing some data, but it seems that Chartcross GPS Test gets a fix way faster.

I added a short, unprofessional Wiki Page so that we can collect this information more efficiently...

http://wiki.xda-developers.com/index.php?pagename=GPS Issues

Please feel free to add your data and improve the page in language, style, structure etc.

For me totally not understandable: The first evening i tried with Romeos 1.704 & GPS it was impossible to get a fix. I cleared cache with HTC GPS Tool and did all the other things, tried with visual gps, gps mouse, glopus and others but i didnt get a fix, even after running 3 hours in the night the sattelites remained red.
next day, when i tried to work on this problem in the same room, same place, i had a fix in a few seconds....

P.S. My Radio is version 1.10.25.25

I was starting to have problems with AT&T stock ROM (1.95.502.5 WWE) & radio 1.02.25.32. All I had to do was disable A-GPS, use quick GPS to download data and then use GPS test to lock on to the birds. Also I have noticed that it becomes a lot quicker to get a signal without a case. Using a metal case sometimes it would become impossible for me to get a fix.

I remember 2 things that are importand(that I dont know how to setup in the PRO):
1. how the GPs handles static situations(dont remember the name) but the lag i get when i'm static or in a slow motion(traffic) is exactly what happend when i changed my BT GPS settings back in the day.
it was called "[FONT=Verdana, Arial, Helvetica]Static Navigation" : will "freeze" the position at very low speed to cancel out the drifting resulting from the natura "inaccuray" of GPS - should be disabled for pedestrian use - see below for details[/FONT]

2. [FONT=Verdana, Arial, Helvetica]Track Smoothing : wrill smoothen the track to remove the "jumps" resulting from the natural "inaccuracy" of the GPS system (10/15 meters) - disabled by default[/FONT]

Just got my Vario IV yesterday and quickly flashed mrvanx's Elite Project rc3 rom.

Stuck in traffic this morning I noticed that any gps app i tried would find the internal GPS, find satellites, lock, then disconnect. It kept doing this for any gps app.

I tried disabling a-gps and the problem vanished, all the apps worked properly and maintained a GPS lock for around 20 minutes.

Its been fine sofar since then...

no one know the NEMA codes to change the GPS's unit settings?

 

[ndda]

Vodafone Touch Pro
ROM: 1.90.162.5 GER
Radio: 1.02.25.19

I tried all
...tweaks with advanced config tool
...registry tweaks
nothing helped.

Switched to Navigon Mobile Navigator 7 (free download on their website inkl. maps for europe to test for 30 days) and thried that.

Works perfect. Bought it afterall...

GPS fix in about 3 - 15 seconds depending on the location (NO QuickGPS in use) // no more GPS lags.

 

[licht77]

Really strange...

after trying a lot of radioroms, tweaks etc. i decided to go back to the initial ROM of my t-mobile branded Vario 4: 1.02.25.19

Guess what? Instant fix. Great reception. No tweaking needed...

OK, battery life is worse than other roms... but GPS is fully working! The difference is not big - its HUGE! With all the other roms, gps was just unuseable (fixes around 20mins or never, disconnections each and every second etc.)!

This brings up a question: Did anybody research the gps related differences between several roms? It would be great to know why 1.02.25.19 is such a difference on our (t-mobile) device(s?)....

Hi,
first of all: I also have the GPS-fix-problem

Now my question:
In this Thread I found this link
http://wiki.xda-developers.com/index.php?pagename=GPS%20Issues
and at the bottom I found this link
http://wiki.xda-developers.com/uploads/JCEspi2005 GPS Lag Fix Raphael.cab
I installed this cab, but nothing has changed...so I'm wondering what this cab should have done? Or does I have to change something after installation?
pls help ^^

Greetings
Chris

BTW: I'm from Germany, sorry for any mistakes
