[PROB] TouchPro GPS lag problems

[omega01]

A lot of people have problems with the TouchPro GPS especially for pedestrian use...

From stock the TP GPS is quite unsable in car especially with TomTom 7 and totally unusable for pedestrian use.

After 2 weeks of reading and testing tweaks, here are the results of my tests and the applied tweaks to enhance the GPS performance

A. With Advanced config 3.2 http://www.touchxperience.com/fr/ou...ads/9-advanced-configuration-tool-32-cab.html

1. disable A-GPS
2. disable GPS logging
3. logfile name must be empty
4. old logfile name must be empty
5. maximum size of logfile must be 0
6 delete the files : \windows\GPSLogFile.txt and \windows\GPSLogFileBack.txt

7. it seems that if TomTom is installed on a fast microSD decrease the lag(have to test to be sure)

With those changes car usage will be quite perfect

B. Then edit registry with TotalCommander http://ghisler.fileburst.com/ce/tcmdpocketarm.cab

Under: HKLM\SYSTEM\CurrentControlSet\GPS Intermediate Driver\

- Drivers\GpsOneDevice\PollInterval -> 100 (default is 1000)
- Drivers\InputBufferSize -> 512 (default is 4096)
- Drivers\OutputBufferSize -> 512 (default is 4096)
- Drivers\SleepOnNoData -> 100 (default is 1000)
- Multiplexer\MaxBufferSize -> 512 (by default not present, you have to create it)

Tests to be done with buffers at 256...seems to be a little better
Tests to be done with other PollInterval value...seems to "drain" battery

With those tweaks pedestrian usage will be much better but not perfect...I explain.

You have to walk for a least 250m in order to have a reposition with mouvement on the map (before that, speed is always 0km/h) and then if you continue to walk there is quite no lag...and the speed reflect reality

...BUT if you stops you have to walk again for a least 250m in order to have a reposition with mouvement on the map and then if you continue to walk there is quite no lag...

Very strange indeed...

I hope this will help people...please test and feedback.

PS : tests were done with
TomTom_Navigator_7.450.9028_R3_VGA_black_edition
GoogleMaps 2.2.0.16 -- http://www.google.be/gmm/GoogleMaps.CAB
GPSTuner 5.4 -- http://www.gpstuner.com/download/GPSTuner_v5.CAB

I noticed GPS problems yesterday with Route66. Havent have time to test GPS lot before, just checked that it can find satellites and really works with Route66.

First while driving, Route66 got fix to satellite pretty quickly, but drop it then after couple seconds. Then couple secods of lag, again found satellites, couple seconds ok, drops again. This keeps going over no matter what, moving or staying stopped.

I then did soft-reset, no help. Then tried Google Maps with GPS, that worked no prob. After using Google Maps I returned to Route66 and strangely satellite fix was ok...

This might be just random satellite fix problem, but strange enough

Many of us have/had that issue so I can confirm you Its a device issue, not a satellite situation. The registry tweaks minimize that problem but I hope HTC solves the problem in his next driver/radio rom/... and the users hasnt to tweak their devices (95% of the users probably will never read this forum and they dont know how to "tweak" their devices

Thanks for sharing. I 'll check it.

Thank you!

I applied all the patches, my TP still doesn't want to find the sattelites...

F.....g hell!!! I tried anything,and morning I've got a fix with 5 satellites in 20secs,so it looks nice(yesterday evening I did the tweaks). But after 4 hours it can see 1-2 satellites,sometimes 3,very rarely 4 under blue sky. So 2 hours of my travelling from city-to-city I didn't get a fix! Co do pici s tym je!!??(sorry for slovak lng,but I cannot speak it english,because so wrong words english language doesn't have). I bought an useless technology and HTC is rolling on the floor laughing,how the customer is stupid. F..k them all with their technologies. Another thing is wifi...no comment is better. I will maybe buy an crazy Eten with Sirf3 and HTC with their stupid Qualcomm can go to hell. For what are all the technologies here,when they are working <20% of time? I am so angry on HTC,so when my kind of device will appear,I will immediately sell the Raph.

Same here... Don't know what else to do...
I believe I will never be able to use the GPS...
Ain't that a shame

Cheers.

 

[Flippy_TK]

But I don't get it, it used to work the first days...

for such an expensive device it is...

For those how have still problems

1. Hard reset
2. Applied the tweaks
3. Download last QuickGPS
4. Install TomTom
5. Have a little more patience...

Gook luck.

Did all that and the bloody phone is still not getting a fix on satellites...

 

[TomasNM]

I am confused in other way...
Why it does lock the satellites in 30seconds and it sees 8 sats.and few hours after it has problem with seeing 3 of them at the same place with same weather conditions? I believe,that tomorrow(when I will not needed to have the fix,anyway I will try it) will fix the satellites ASAP. Do the Raphael have a status-sensor,that knows,if I need it right now or not? That's my opinion,while it doesn't work,when I need it and works when I testing it...
I will s..t on whole GPS technology and I will trust the plain maps as before(unfortunately,that costs me some money/energy that I spend for that).

Totally amazing

This is just amazing. Thank you!
Now I get a fix in 10-15 seconds. Earlier it took several minutes... totally amazing...

tried this also and been driving around for almost an hour without results is that enough patience?

 

[lepermessiah]

hmm, my gps was working normally, applied these patches and nothing changed..still working normally (no lags etc.)

 

[clandestino_usr]

Applied all the patches except one (I kept A-GPS on), and after testing with iGo it's working like a charm. With the latest QuickGPS data downloaded, it can still take - seconds to get a fix, but the positioning is accurate (no more 100-200m lag), the devices sees 4-6 satellites in the Belgian sky, and the navigation is finally usable on the Touch Pro. I'll make regular checks in the coming days and I'll report the results. Thanks for the tweaks!

With A-GPS enabled the GPS works great. I had it in my pocket with GPS tuner running while running in a forrest and he didn't lose my position and no lag. The problem: with A-GPS enabled TT7 loses the fix every second. Like 1 sec there is a fix, next there is not. And it keeps doing that. When I disable A-GPS it takes way longer to get a fix with TT7 but it holds the fix.

Tip: driving around makes it harder for the gps to get a fix.
