GPS problem with cooked roms

[vratko28]

This is usual thread all over net..
I have problem, a big one... Every cooked rom I have tried works great but GPS dont work. Fix takes 15 - 20 min quickgps updates normaly but no fix... with original rom and quickgps updated fix is under 30sec but i have problem with touch screen on original ROM. so i have spend 15 days of experimenting, flashing various roms, radios but no luck....

interesting is that when i connect external gps antena with amplifier i get fix around 1 - 2min.... then it works with integrated, but 2 hours later same problem...

Kaiser130 is my device

tried roms: shifu v1 & v2 basic & full, Dutty's WM6.1, REV_ROM_V8, SimpleOsManila, AtheneOS....

also i have tried exporting registry branch from original rom for quickgps and copyed quickgps files over but no luck.
no luck

I have used almost all of these roms and my lock is in 2-3 minutes. 1st, make sure you are using the recommend radio. If you use the wrong Radio, you will never get a lock. Also make sure it is not just your area; if there are only a few sat's then the GPS module in the phone will take for ever for a lock.

C'Mon dude really... 3rd post and you come out dropping bombs like "every" and "it's the usual" and "a problem... a big one"

I have used many different ROMs here too and have not had a single issue with GPS working!

I think "every" and "usual" is disrespectful to the cooks here and that your issue is likely hardware (hence your comment about it working w/ an external ant) or possibly between the screen and the seat :eek:

have you tried gpstest to check your com ports and then set it manually?

[raf1987]

I also had the same issues :(

already changed the com port and radio from 1.65.16.25 until 1.70.19.09 (KAISER Radio)

[vratko28]

As u see raf1987 has same problem as me, yesterday I have tried original HTC WWE 6.1 rom but with same result.

I dont mean to disrespect cooks, and dont see what is problem with me having 3 posts??

k2rolla503 Yes I have tried gpstest, nonigps plot.... they find satelites but no fix 1 to 4 satelites all time but no fix.. signall strength is normal in all roms (graphicaly to me).

I too have the same problem.

I find the GPS fixes to be very flaky. I've used both the ROMs from Laurentius up through V10 and now using Phoenix II.3.

Laurentius ROMs I found I had much faster lock time if I downloaded the ephimeral file right before I used my GPS. We are talking 24 hours between uses. This could mean the difference between a 2 minute lock and a 20 minute lock. I've never gotten GPSTest to show me anything other than starting...

On Phoenix II.3, the ephimeral file only last for 3 days instead of 7 like Laurentius. Once I saw the fastest lock in my life ever on this ROM, it literally must have locked in 15-30 seconds. I have never seen it do that again. Currently it's taking me a good 10-20 minutes to lock on average. I have to start up my GPS 10 minutes before I go anywhere just to get it warmed up.

I've also tried fiddling with the assisted GPS setting on both ROMs. I found that with Laurentius the fix is slightly faster. On Phoenix I haven't noticed any real difference in getting a fix aGPS vs GPS. Nor do I find it assists in tunnels.

The only thing that really bothers me about aGPS is that I get that dialup connection dialog that says it fails to connect every time I use TomTom. I have to hit dismiss before it appears to start trying to get a fix. I've tried reapplying the connection settings for AT&T, that didn't seem to help much. It is super annoying.

In the end, GPS does work, but like the OP, I found that my fixes were consistently faster on the stock ROM than the cooked ROMs. I too mean no disrespect and I appreciate the hard work that goes in to each and every one of these ROMs even if I don't use them. I too like the OP just want my fix to be as fast as those claimed here and elsewhere. It can be frustrating to hear about these fast lock times and have to suffer with long lock times. It's especially annoying to me because I travel for business a lot and find that I am now nearly half way to my destination before I finally get a lock.

While I may not have many posts, I do follow these forums regularly. I hope that my input will be constructively used to find an answer if there is one to be found.

I have no issue using L26's TF3D V4, Athine OS Jan 22, Mbarvian Solace 1.5 and Josh' Revealed 21500. All has the GPS working fine. I'm not that particular that I measure individual response time.

As long as it locks within 1-2 mins (from nothing), it's ok to me.

[raf1987]

hmm.... i think , i found the solution... don't know if it could work for others

now, I use PDA corner from Abusalza... with Radio version 1.70.xx.xx

so, after flashing your new rom... make sure you update the GPS support programs like quick gps , etc

then, execute your GPS program ( I use Garmin for this).. and make sure you are outside of your house, or apartment, or wherever..

the reason why my tytn II could not find satelites is because I did it in my house, did not think that outside my house could work (because my Trinity could detect satelites in my house without any support GPS program like quick gps) :(

then... your tytn II should detect the satelites and GPS is activated...

NB: sorry for my bad english :(

I am having the same problem. The original Three (Australian) ROM would get a GPS lock within seconds.Now, I take 20smins to get a lock.

ROM version: AthineOS WWE
ROM date: 1/22/09
Radio Version: 1.65.24.36
Protocol version: 25.94.40.06H

I have just used GPS test and the only thing I changed was the baud from 4800 to 9600. Will try it out later, but hope it works.

PS Most of us know that GPS works only if there is line of sight with the satellites, so yes, I am outside on cloudless days when I try to get locks.
PPS If it dont work, I might go back to official ROM. http://www.htc.com/au/SupportDownload.aspx?p_id=13&cat=2&dl_id=342.

flash back to WM6.0, there are no problems with gps. every fix in 30 sec.

[vratko28]

Hmm I would like to go back to 6.0 but my provider has only this rom 6.1 for download that has touch screen problem...

Any link to 6.0 WWE would be helpful

[vratko28]

Found 6.0 sry.... ill try and post reply

[anagarika]

Search the Wiki. There're links to various WWE versions.

[jorakae]

Hmm, I wonder then what the difference is between 6.0 and the higher version that causes this inconsistency in locking. This would seem to indicate software issue rather than a hardware issue. I love the newer ROMs but the inconsistency or complete latency in getting a lock can be extremely annoying especially when you need a lock quickly.

I changed the baud from 4800 to 9600 and so far, the GPS locks within 30 seconds. I need further testing, but perhaps the default settings of the cooked ROMs is causing this problem?

[vratko28]

I have tried and sucesfuly cooked ROM from stock firmware, added some apps, replaced buggy touch.dll so far so good ROM is 6.1 (WWE 3.31.xxx) using radio 1.65.20.15 i think.

Yesterday cloudy weather with rain i got lock within 4min cold start after flash, today morning warm start 2min (still cloudy no rain) and around noon no clouds got lock in 5sec.


Big THANX to SHIFU for help with dll

[ManishG]

[newwonder01]

Hi,

I have different problem on GPS, I am using Garmin DK Series, dated 01/16/09. The problem is if use GPS for more then 10 min, back of the kaiser started to heatup, if I turn it off, after a while it is fine. Otherwise, it is detecting the GPS faster. I have downloaded QuickGPS & SeaSGEE.

Is anyone having these problem.

Thanks

[bteljuice]

Vratoko:
5s ????????????????????????? Please do enlighten us.

Newwonder:
Can you please provide SeaSGEE link. What does it do? is it like quick GPS?

[newwonder01]

Yes, It is same like QuickGPS. I got it with the Garmin ROM.
