On the official htc rom I got gps working perfectly on all gps apps (tomtom and google maps) by changing the gps settings to 38400 and it instantly worked locked in on location in about 10 seconds did no other tweaks or anything I think maybe 6.1 uses a different baud rate then 6.0 did maybe worked for me
[Tilt, TyTN II, MDA Vario III General] Karolis:
Messing with baud rates might somehow magically speed up the lock, but it will sure as hell not fix the original problem which is that QuickGPS data is not being used.

By the way, I've just tried my device with all possible baud rates, keeping it on for a minute before trying different one – no lock.
[Tilt, TyTN II, MDA Vario III General] sebbes:
I have to agree, in fact, the GPS sensitivity seems to be very unlogical...

Sometime you install ROM A Radio AA : it works fine

Then you try ROM B Radio BB : bad

So you go back to ROM A Radio AA : bad (!)

Here is the AGPS+ driver by Orange (warning : it will download data everytime you start using the GPS... but it's free on Orange networks)

[Tilt, TyTN II, MDA Vario III General] pachjo:
Stupid question...

How do you get rid of the AGPS+ driver?

I disabled QuickGPS and installed the orange one and it did not get a fix although connected to ornage network.

Decided I did not want this so removed app and reverted to QuickGPS but the orange connection still happens every time I start TomTom whereas it did not before?
[Tilt, TyTN II, MDA Vario III General] sebbes:
Going to :

HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS> EnableAGPS = 0

Should disable it.

Thanks dude, I shall do this.

I am looking on the net for a registry editor to use on my wm6.1 does anyone have any tips on the best or worst wones out there?

GPS issues - some notes

I have installed radio 1.65.20.29 and everytime I can get the cold start GPS fix in about 5 minutes (tried Neon 1.58.25.17 and stock 1.65.16.25 - same results). QuickGPS is set to my country region and AGPS is disabled. Have tried different settings (AGPS enabled, QuickGPS using different servers to download the data...) and it seems 99% screwed up anyway.

Got a log from VisualGPSce if someone might be interested. It is a last minute before getting the fix (the whole process took 5 minutes).

I might starting to think it's a QuickGPS issue, as when using old wm6.0 with radio 1.27.12.32 i could get a fix very quickly, but last few weeks before upgrading to wm6.1 it sucked a lot, too...
[Tilt, TyTN II, MDA Vario III General] sebbes:
Hey Gabriel, I'm 100% inline with your conclusion

I went back to my stock (WM6.0) Orange ROM with Radio .32 and I can get a fix in the house in 30sec max.

Try this one, runs from your PC to modify the PocketPC registry (very handy)

[Tilt, TyTN II, MDA Vario III General] gabriel31337:
I'm really considering the wm6.0 rollback to Q-Mobile v1.2, it worked like a charm.
[Tilt, TyTN II, MDA Vario III General] ardsar:
I have contacted HTC Technical support, who are apparently looking into this issue, however the more of us that contact them, the better. Don't use the email support as they never seem to reply to them - use your local telephone number and speak to them directly. We should not have to play around with settings, radio's etc at the risk of bricking our phones, to get correct GPS functionality.

As a side note, i've been playing around with the HTC GPS tool and noticed something very strange. On the radar screen showing the position of the satilites in the sky, i have noticed that some sats are being identified correctly - ie sat 12, but others are showing 55. I thought there were only 26 satelites, or am i missunderstanding the data? Those that are correct also, sometimes change briefly to another high number such as 55.
[Tilt, TyTN II, MDA Vario III General] pachjo:
Kool, all sorted thanks :)

I have QuickGPS back as it was and now when I start TomTom I get a fix within a minute :)

I do not understand what QuickGPS is for as if I update it and it says valid for 7 days this data would be relevant to where I am at point of update.

So if I get on a plane and fly to the other side of the world how can the stored data help determine where I am?
[Tilt, TyTN II, MDA Vario III General] ardsar:
The satellites broadcast two types of data, Almanac and Ephemeris. Almanac data is course orbital parameters for all SVs. Each SV broadcasts Almanac data for ALL SVs. This Almanac data is not very precise and is considered valid for up to several months. Ephemeris data by comparison is very precise orbital and clock correction for each SV and is necessary for precise positioning. EACH SV broadcasts ONLY its own Ephemeris data. This data is only considered valid for about 30 minutes. The Ephemeris data is broadcast by each SV every 30 seconds.When the GPS is initially turned on after being off for more than 30 minutes, it "looks" for SVs based on where it is based on the almanac and current time. With this information, appropriate SVs can be selected for initial search.

When the GPS receiver initially locks onto a SV, the devicedisplay then shows "hollow" signal strength bars. At this time, the Ephemeris data has yet to be completely collected. Once the ephemeris data is collected from EACH SV in turn, the associated signal strength bar will turn "solid" black and then the data from that SV is considered valid for navigation.

If power is cycled on a GPS unit, and when turned back on, the Ephemeris data is less than 30 minutes old, lock-on will be very quick since the GPS does not have to collect new Ephemeris data. This is called a "warm" start.If it is later than 30 minutes, this is considered a "cold" start and all Ephemeris data will have to be recollected.

If the GPS has moved more than a few hundred miles or accurate time is lost, the Almanac data will be invalid and if you are far enough off, none of the SVs that the Almanac thinks should be overhead will be there. In such case, the GPS will have to "sky search" or be reinitialized so it can download a new Almanac and start over. I believe the quickgps data is valid for the area/region you are in, so when travelling on a plane, if you require a quick fix, you will need to download new quickgps data in the country you have travelled to. I say this because, there appears to be region codes within the registry , ie mine is currently set to GB.

QuickGPS Region settings

It looks like the registry change to region settings of QuickGPS (search the forum how to do this) fix the issue with GPS a bit. At least for me (the cold start takes around 5 minutes to get the fix, but) any warm start get the fix in max. 10 seconds! Tested for last few days within range of 50 km from the city :eek: :D

This is more acceptable. :rolleyes:
[Tilt, TyTN II, MDA Vario III General] zalaros:
5 minutes??? :confused: With WM6 installed on my Kaiser the cold start takes around 20 seconds to get the fix ;) With WM6.1 installed the cold start takes around 2 minutes :mad: That's why i will stick to WM6 ;) although i would prefer WM6.1. I wish someone will find a solution...
[Tilt, TyTN II, MDA Vario III General] gabriel31337:
it's very difficult to estimate correctly, I had a cold start also in about 2 minutes, but twice from 10 tests..
[Tilt, TyTN II, MDA Vario III General] D8LOM:
Yeap, I'm having this problem since I've upgraded to the official WM6.1. Before (when I had WM6.0) my TT use start up within 5 sec max!!

htc‘s 6.1 is trash, either wait for your carriers revisioned update version of 6.1(thats if they can even get the bugs out)

2) downgrade to 6.0(your smartest bet)

or

3) wait for WM7

...geez these 6.1 GPS problem threads are getting redundent and annoying, theres a new one everyday..mods is it possible that you guys can like make some wiki for this or something of that nature named "The dangers of Upgrading to 6.1" or something of that genre so that these crackpots who know (or in most cases dont know) what happens when upgrading to 6.1...ESPECIALLY HTC'S version, and do it anywayz thinking their Kaisers are invincible to the inevitable and can atleast see how many of these problem OS threads have alrdy been put out? so they can stop taking up prime real estate on these threads and actually post useful threads and not redundance.
[Tilt, TyTN II, MDA Vario III General] omar302:
I have noticed something, but I don't know if its related.

I am using Garmin Mobile XT, when I had WM6 (official), clicking the GPS signal, it would show that GPS is connected via intermidiate driver. But in WM6.1, it will show COM4:COM4.

Can anyone figure out why is this? could it related or is it nothing?

right now i am using ROMeoS V2.2 with Niki 1.58.25.17. The GPS is fast, but cold start after a soft reset is slow. I can see the difference between WM6 & WM6.1 using GPS speed sentury as follows:

WM6:

Upon starting up GPS Speed Sentry, the location of satalites are already there, its just a matter of trying to read them.

WM6.1:

Upon starting up GPS Speed Sentry, the location of satalites are NOT there, it has to find them and then read them.
[Tilt, TyTN II, MDA Vario III General] Boinng:
HTC's 6.1 is easily the best ROM I've used on the phone, including various cooked ROMs from this forum. It's fast, stable, direct draw is improved, and I really can't fault it except for this GPS thing, which as far as I can make out affects all 6.1 ROMs (or at least the majority of them).

I appreciate there's plenty of hate for HTC around here, and it's never "cool" to run the official HTC ROM, but many of us still prefer it. It's an HTC phone after all, it just needs an HTC fix.
[Tilt, TyTN II, MDA Vario III General] Karolis:
Which might just never arrive ;)
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
I initially thought that as well but aside from the GPS issue, I've also now had a few cases of the ringer volume going down to zero on it's own (meaning I've missed calls), some screen drawing probs with the new threaded Outlook/Messaging program and quite a few pauses/momentary hangs. None of these problems were present for me in HTCs original WM 6.0 release for the TyTN II.

I like your optimistic use of the word 'just' in there. I hope HTC see it that way :D
[Tilt, TyTN II, MDA Vario III General] khaytsus:
Seriously? A rant about redundant threads from the person who just started two threads about WM7 coming from information that was in itself redundant?

Dude....take a chill pill they are only threads and if you don't want to read them........don't!

uh...the hell are you talkin bout bro..theres a new HTC 6.1 problem thread EVERYDAY!...mostly about GPS. The windows mobile thread i brought up was just for knowledge purposes from different tech sites...you dont see a windows mobile 7 thread EVERYDAY with updates about the OS, like how you see for these 6.1 problems... so how was my thread redundant?

Guys,

If you can get a GPS fix from a cold start in under 30 seconds then I'd like to know:

your ROM

Your Radio

and your model (under the battery; mine's a KAI130 I think....)

As it stands I'm seriously thinking of swapping for a Touch Dual as none of the Kaiser's benefits are benefits to me....rubbish camera.....rubbish keyboard....rubbish GPS. At the moment I'm struggling to love this device.
[Tilt, TyTN II, MDA Vario III General] gabriel31337:
Holy ....

I have stopwatch enabled and running for over a 15 minutes now and I still have no fix, even with the great view of 11 sattelites... cold start... That's what I call a great HTC upgrade :mad:
[Tilt, TyTN II, MDA Vario III General] gabriel31337:
20:32 to get the fix...
[Tilt, TyTN II, MDA Vario III General] gabriel31337:
after a softreset and another start, 15:23 to get the fix

now that's bad :eek:
[Tilt, TyTN II, MDA Vario III General] N1TeSH1FT:
Well I had it on my Device for about 2 or 3 Days and as with many other ROMs, I experienced exactly the same issue. Took about 2-3 MINUTES! till I got a fix, whereas I had the impression that it took only about 30-40 secs on the old ROM. A hot fix takes about 1-2 Minutes whereas the old one took about 10-15 seconds.

Nevertheless, I will try other radios too, because my Laurentio v8 light is exactly as slow, but I have radio 1.58 on my device.
[Tilt, TyTN II, MDA Vario III General] Karolis:

[Tilt, TyTN II, MDA Vario III General] dengi_it:
Having the standard HTC - WM 6.1 of course I have the same issue.

The workaround that is basically working to me is using the freeware "GPS Test", advised by some user here.

I launch it and wait (for a few seconds or very few minute as 1/2 min) the program to show "GPS Connected". At that stage I minimize this program without exiting it and then launch my navigation program (Wayfinder) and it immediately finds the GPS active and running

This is the only workaround that is ok to me!

Nothing to do with QuickGPS in Italy where I live and use it

Of course QuickGPS + Wayfinder were perfect with WM 6.0
[Tilt, TyTN II, MDA Vario III General] Karolis:
GPS Test might speed things up, but it is not a solution. I always do it that way and it really depends on many things. Sometimes the lock is under 5 minutes, sometimes over 10.
[Tilt, TyTN II, MDA Vario III General] dengi_it:
I do agree. Infact I defined it just a "workaround", waiting for a serious fix by HTC.

But I guess it may help many users, given that without GPS Test I see that sometimes my navigation program takes a lot of time (maybe 10 o 20 minutes??) just to find and connect th internal GPS and sometimes it is not successful!!

In my opinion the long time taken is partially due to issues in fixing the satellites, other times it depends on the fact that the internal GPS unit is not found! My guess is that WM 6.1 use dynamic resource management (Ports??) that cause Tomtom and other navigation programs to have troubles in finding it! That might be why some users have less pain defining an "external GPS" in Tomtom, that is something that doesn't work with my Wayfinder

So... waiting for the fix... till now GPS Test helped me always in connecting the GPS and fixing satellites in a reasonable time
[Tilt, TyTN II, MDA Vario III General] cool_scorpion:
No issues with my device

Hi all - I have been using WM 6.1 for a month now, and have noticed that on a "cold start" it takes the GPS about 2 minutes to link up to a sat. However, after that it is less than a minute. So guess I am now plagued by this issue yet ! I dont use Quick GPS while roaming, which is a lot.

BTW what softwares would one suggest for maps - particulary for the Middle East ?
[Tilt, TyTN II, MDA Vario III General] Farsquidge:
Garmin ME V4 is probably the most up to date mapset if there is such a thing in Dubai! but you need to use this with a Garmin GPS10. Destinator can be used with any BT GPS but the maps are a little behind times around here.
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
That was the same in WM 6.0 though (there's that option to use automatic GPS management or words sim to that effect). Tomtom worked fine under the old OS so the problem is not the OS itself, it's that HTC haven't refined the drivers responsible for GPS (within the radio code) to work properly with WM 6.1.

HTC and driver issues, who would have guessed it:rolleyes:
[Tilt, TyTN II, MDA Vario III General] gabriel31337:
Another GPS status

OK so it looks like the GPS is getting a cold fix outside with clear sky in about 4 minutes, any other warm fix is being received in max 20 seconds (usually 10 seconds).

This is far more acceptable.

No changes made to the settings.
[Tilt, TyTN II, MDA Vario III General] Farsquidge:
Now here is a puzzle for you.. Using stock WM 6.1

In Abu Dhabi I can get a cold fix with QuickGPS updated within 5 mins and warm fix within 60 seconds.

I have just arrived in Boston MA yesterday and still have not been able to update QuickGPS (server not found) and after 10 mins stood outside I have still yet to find ONE satellite!!

Have the Homeland Security guys been messing with the sat signals here or enforced new protocols on MS or the chip/firmware manufacturers to stop potential terrorist activities? I know I'm from the Mid-East but I only want to find my business trip destination..:o

I will be in UK after the 11th and will check it out there...
[Tilt, TyTN II, MDA Vario III General] myteematt:
I just travelled from Florida to New York on the East Coast of US and had to downgrade to one of the older Q-mobile roms that used the 1.27 radio because I found it to have much quicker GPS fix both cold and hot. I think the 6.1 roms as cool and zippy as they are don't have very good GPS signal or fix because of their newer radios. Hope this helps :)
[Tilt, TyTN II, MDA Vario III General] sebbes:
Do you mean a WM6.1 can work with a 1.27 radio ?
[Tilt, TyTN II, MDA Vario III General] myteematt:

[Tilt, TyTN II, MDA Vario III General] Farsquidge:
HA!! got it!!!

All you guys complaining of poor WM 6.1 GPS (apart from the few psudo leeches!!) are suffering from and imposed 1sec (time not Datum...) GPS offset to Western locations!

It IS!! a security issue... as it still enables any GPS mapping unit, produced from 1st April 2008 (including HTC 6.1 update!) once locked (OK this can sometimes take an F'in age) to work, but in the mind of the Homeland Security freaks! a GPS weapon would not work as it would have problems getting a fix???

Go figure??? :confused::confused::confused:
[Tilt, TyTN II, MDA Vario III General] Sideburnt:
has anyone tried using SeaSGEE its a piece of software that works similarily to QucikGPS, people have has significantly reduced lock on times when using it.

I have literally just started to play around with it, CAB's can be found via Google, there is a VS thread in XDA.

let me know if you folks have any better results.
[Tilt, TyTN II, MDA Vario III General] Boinng:
Anyone have any more info on that? It has a crazy ring of truth about it. Anywhere we can look at that offset, if it exists, and/or change it?
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
So if I understand whats being written correctly by Farsquidge, Microsoft has to make the latest operating system with a deliberate GPS fault... In the words of Victor Meldrew, I don't believe it. Isn't a buggy HTC provided GPS driver/radio code far more likely? That would also explain the instability with signal reception (all bars one minute, one the next). Additionally it would explain why users who've reportedly dabbled with other radio modules, have succeded in fixing the TyTN IIs broken GPS under WM 6.1.
[Tilt, TyTN II, MDA Vario III General] Boinng:
Well the simple truth is we don't know, we can all shout "driver issue!" till our lungs burst, but that doesn't get us anywhere at all. It also doesn't really explain how, once a lock is finally achieved, the Kaiser's GPS actually works quite well in my experience.

IF there are other 6.1 radios that work (and as far as I can tell, they're only those borrowed from other models that invariably have some other form of incompatibility) then that suggests that HTC have got a perfectly working 6.1 GPS driver, doesn't it? So why is it broken in the generic update for the Kaiser?

I find Fairsquidge's theory quite far-fetched too, but it's undeniably interesting that his own kaiser worked flawlessly in the middle-east (to the extent that he was arguing with people here about the issue) and immediately started having problems when in the west. If it's not some deliberate crippling, it may at least point to some other factor at work here, so I'd quite like some more information on it, if anyone has it.
[Tilt, TyTN II, MDA Vario III General] Flying Kiwi:
Our experiences differ in that regard. Although generally once a fix is obtained with TT 6 under this new OS build, it hangs on, sometimes it looses the satellites - more so than under WM 6 for me. Even when it does get a fix though, when remaining stationary the reception bars fluctuate wildly under this OS whereas under WM 6.0 that wasn't an issue for me.

They have indeed - the driver is IN the radio code (thats just one of its functions along with dealing with aspects of the camera, ordinary phone reception and other things). The big problem is as you mention, I've not heard of one that has everything working properly together. Users shouldn't have to sacrifice a camera for GPS etc. Sorry if my post sounds like I'm shouting about drivers, it's just thats, by far, the most likely cause for these problems.
[Tilt, TyTN II, MDA Vario III General] Foxhunter123:
