Hello,
I bought a brand new 'HTC - Kaiser' (precisely a 'HTC - TyTN II' directly from Orange in France), in order to replace my old 'HTC - Hermes'.
First, I was surprised not to see a GPS option in the 'Communication Manager'. As you can switch ON/OFF wifi or bluetooth, you should be able to switch ON/OFF the GPS, isn't it ?
Secondly, I installed Tomtom v6.032 on my PPC, but I could not get any signal at all. I went in the options, and tried with all GPS option devices, with no success.
With 'Built-in GPS receiver' and 'Other NMEA GPS receiver' options, I always have "No valid GPS signal !". Do I have to start GPS somewhere on my PPC before starting TomTom ?
Thirdly, I looked for help on xda-developers.com here: http://forum.xda-developers.com/showpost.php?p=1735972&postcount=112
I followed his recommendations, I changed:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Drivers\GPSOnePort]
"CommPort"="COM1:" (instead of: "COM0:")
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Multiplexer]
"DriverInterface"="COM0:" (instead of "COM4:"
And it after this I could have some signal. But then after shutting down Tomtom and reopen or after a soft reset, it does not work any more, at all ! What happens ? I don't understand.
Why my GPS just not work out of the box ?
Please help ! I switch to the Kaiser for the GPS feature, and it does not work :'(
I tried all my test outside with a clear weather, waiting for about 3 minutes each time.
it should work right out of the box.
for me (i have a tilt) gps is on com4. i use tomtom and you have to make sure the correct com port.
I could be wrong but I believe that in tomtom if you get the message "no valid GPS signal" that actually means every thing is set up correctly. you just need to wait, could take some time. tomtom starts the gps itself. watch the leds on the phone. when GPS is on the right LED will flash.
you may want to check out some other programs. tomtom does seem to take a little longer to get a fix in my opinion.
BTW check out my signature, you can use navizon and make some money once you get that gps working
There's no seperate GPS connection. The GPS just uses your data connection. If you can connect to 3G, then your GPS will also work. Try using Google Maps and clicking "Use GPS", leave your phone in one spot for a few minutes and see if you can get some sattelites that way.
As always, someome smarter can correct me if I'm wrong, but this is from my experience.
There is no way to "turn on" gps, programs access it when they need it, and it's off when they don't
Your first fix can take up to 45 minutes, although min eonly took about 5.
If you look in the extracted HTC cabs threads, you can find a program called "HTC GPS tool" Run this and select "clear memory" as the option, and that'll get a fix after a while. after that, After soft resets you should use "cold start", I think...
After this has fgot a fix you can use other programs on the COM4 channel.
Hope this helps
I have had my Tilt for about 2 months. Recently, I took a trip from L.A. to N.Y.C. As soon as I got to NYC, I ran QuickGPS, but was entirely unable to get GPS to work at all during the week I was there (queens, manhattan, roads, etc).
I posted an inquiry about backing up and hard resets. Rather than getting an answer to the question, I was given direction to make sure my GPS really didn't work.
That chain pushed me to GPS Test v1.04 by Chartcross. It is free, and can found on the web and on this forum. In NY I could not get a signal no matter what even running it.
When I landed in LA I ran it again ... it stayed at "Starting Up" for a while, but then miraculously started showing bars.
So --- I recommend that you (1) run Quick GPS, (2) install this program, and (3) let it run and run and run. Also make sure you are in an area where GPS is accessible.
It can take a very long time to get GPS to work on the tilt. Many times, it takes longer to find a signal than the trip you were hoping to TomTom through. Its the nature of the beast.

Yep, like all the others have said leave it fore longer. 3 mins isn't enough time. If after 30-45mins of being left in one place (no moving it around!) with a clear view of the sky for the first time and TomTom is still saying "No valid GPS signal" then start worrying...
Thank for your enthusiasm. I carefully read your post, here is want I discovered:
You mentionned about having a 3G data connection. First I was wondering why do you talked about that: this as nothing to do with GPS. Then I thought I should give it a try. Up to now, I haven't yet put my SIM card in my brand new 'HTC - Kaiser'. I didn't mention it in my 1st post, as I though it could not have a link with my GPS problem. I put the SIM card in the phone, then started Tomtom, I was surprised to see that a 3G data connection was automatically started, and a few seconds later, the GPS worked perfectly.
I can't believe it, I could not have the GPS working because there was no SIM card in my phone !
First I thought that the data connection was for retrieving Tomtom traffic info online, but then I discoved that even with 'HTC - GPS Tool v1.1.1.0', a 3G data connection is started prior to getting my localization.
I read about QuickGPS, and learnt that it is the thing that causes the 3G data connection to start prior to getting my localization.
Why is QuickGPS starting automatically ? Is QuickGPS compulsory for localization ? Can I stop this behavior and have everything running through GPS ?
Chris
MAYBE IF YOU TR THIS ONE
I HAD THE SAME PROBLEM AND IT WORKED FOR ME
JUST ASSIGN THE INCOMING PORT TO COM4, AND OUTGOING VIRTUAL COM5

GPS and 3G have nothing to do with each other. They are too completely different things.
GPS does not need 3G to function!
Some GPS programs (like google maps), do require a internet connection to download data, thats when 3G comes in (not necessary, could use wifi and gprs instead).
What is strange is that in Orange ROM (at least in France), a GPRS connection is made automatically each time you want to use your GPS. If the GPRS connection is NOT successful, you can not use the GPS (with tomtom, or any other testing GPS tool). How can I change this behavior ? I do not have an unlimited GPRS subscription !

It's required GPRS connection because you might have selected tomtom plus services such as Traffic, Weather. Just to be sure, take out your SIM or turn off the radio to see what happen. BTW, flash a different ROM is another choice.
Did you installed Google Navigator as my Kaisers GPS unit stopped to work after i installed GN?
On Orange ROM (in France), everytime you want to get GPS, you first have to connect to the Internet. It is not link with TomTom Plus, because even with HTC GPS tool software, you need to let the phone automatically connect to the Orange network prior to getting your location with the GPS. If you do NOT have a SIM card and the possibility to connect online with your phone, you get NO GPS location.
Please, help

As NGHIEM said above, flash a new ROM and this behaviour will stop. Try Duttys or Schaps for best stability etc.
I am using an AT&T Tilt with Garmin Mobile XT and there is an option to turn off Internet Data (Traffic, weather, etc.) in Garmin. If I want to use the GPS with no radios on I have to disable the Internet Data option otherwise the program tries to make that connection first and never acquires a fix. That may be part of your problem. I also just tried the HTC GPS Tool with no SIM card in flight mode and it got a fix in under 2 minutes inside my house by a window. Garmin also started fine. The GPS is an independent receiver and should require no other data. It appears that some other program is starting along with the GPS and trying to access the Internet. Like others have said before you can probably solve your problem by flashing a new rom.
I think I have found the solution:
- In the registry change:
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"EnableAGPS"=0 (instead of: 1)
Now everytime I use my GPS (with HTC GPS Tool, or Tomtom), the automatic GPRS connection is not started !
Please give your feedback about this.

What is this file about ?
I've searched and searched but couldn't find it (only references to it in other ROMs). Could someone either please post the HTC GPS Tool.cab or point me in the right direction as to where I can find it?
I know it's in a couple of ROM releases, but I'm happy with what I have now and just want that file.
Thanks, guys!
EDIT: Nevermind, guys. I found it. Thanks!
No card is found
I have installed TomTom on my new Kaiser and downloaded the free citymap, but when I then run TomTom it says: No card is found. What am I doing wrong?
Ok I successfully installed TT6 on my Kaiser, which currently runs dutty 3/8 rom and niki radio. I have Kaiser Tweak installed as well. Everytime I open TomTom it wants to connect to GPRS. From my previous experience when GPRS is transferring data it uses MB's, which I am charged for because i do not have any data plan, nor do I want one because I am usually in hotspots. In addition, I have quick gps, gps test, and gps tool, applications installed on my device.
I was able to get a connection yesterday without using GPRS. For some reason I clicked on Traffic Updates in the configuration. Now everytime i connect to TT6 it opens the GPRS connection. When I hit cancel with GPRS I cannot establish a GPS signal.
Will I be charged for GPRS connection if data is transferred if so, how do i use my TT6 application to avoid any service fees or any transfers that will costs me money.
edit1: I also tried disabling my traffic updates however no success
edit2: i have my own software with all maps. I did not dl any of the tomtom6 software featured in this forum so this issue may be different. In addition, i searched this similar problem with confusing results.
Did you try disabling traffic updates? That is what is connecting...
yes i did...
this shouldn't be a difficult thing to answer for those who don't use any type of data connection (medianet, gprs, 3g etc) and use gps.
go into tomtom plus services and disable wireless data, if that doesnt work, and since you are a legal user of tomtom, then why dont you contact their tech support, that's what they are there for

You can you the program NoData http://forum.xda-developers.com/showpost.php?p=1325870&postcount=7 to disable GPRS traffic.
thanks i'll look into the "no data" application.
hmmm but i can do the same thing with kaiser tweak, however tomtom cannot establish a signal.
Another thing to check is taht A-GPS is DISABLED,if not it will try to get GPS fixes via cellsites and download the sat data as well whenever the GPS is activated.
Good Luck

i think u solved the issue. I'll let u know in a few hours but as i can see from bein indoors the gprs 3g connection isn't popping up. Thanks for everyones input. I figured there was an easy solution.
Ok that solved the issue of connecting to the net but now I cannot get a satelite signal anywhere in Boston.
You have to try out couple different things. First off, try a different version of tomtom. Do a search and should pop up with couple diffrernt versions. I can tell you that my version doesn't connect to data at all. Maybe the A-GPS option works, but you're not doing something correctly. There's a tomtom tutorial somewhere. Do a search for that. Verify COM4 or whatever com gps is on. Test out HTC GPS tool to see if you can pick up any satellites. Could possibly be the radio. Many different things you can try out here.

I understand however I have tried everything. It was working correctly previous to when I hit traffic updates. I tested everything and then reinstalled the program onto my device late last night. It previously worked with niki radio and dutty rom on com4 with almost all the bauds. The A-GPS system did not make it work and it also attempted to connect to the internet. When I try to run AGPS now it doesn't connect to the internet even with it enabled in Kaiser Tweak after a soft reset.
TomTom and WM 6.1
I just switched my ROM over to WM 6.1 ... tom tom looks like it is running fine, but the "check for updates" button under advanced features now just returns an error. Any thoughts? I have disabled my cingular proxy, so that should not be the problem.

whatever you do try not to hit traffic updates. It complete f'd up my gps application, gprs, and my medianet is no longer working for what I can see. They are all enabled too, which makes this even more confusing now. Thinking about doing a hard reset cause I have back up of everything on my pc. Just don't want to be bothered with spending hours updating right now.
ok fixed going to have moderators remove this thread cause nothing usable came out of it.

Yes You are correct and I apologize.
Ok, first I disabled agps and then was not able to get a signal anywhere.
2nd, I removed all TT6 Apps from my phone and TTHome from my PC
3rd, I Removed my SD card and any remaining applications or files that had anything to do with TT6 or the term "navigator" by using the file explorer.
4th, I moved the TT6 cab file to my device and ran it.
5th, I then formatted my SD card from my PC.
6th, Inserted the SD card back into the phone
7th, Moved the Navigator Application from the "Crack" file onto my SD card.
8th, Went into Program Files on my device and deleted the Navigator file that was there.
9th, Moved the Navigator application from the SD card to the navigator file on my device which would be under "program applications". I also moved the US and Canada Maps onto the device.
10th, I reinstalled TTHome onto my PC
11th, Connected Through active sync and set up the TT6 on my device using the appropriate baud and com4.
12th, After installing the updates from TTHome. I again removed TTHome application from my PC. Somehow, only running the updates once will allow the program to work. If I reconnect my device through active sync and TTHome is still installed I will be unable to use the application again on my phone because it will not get a signal if I reupdate.
Hi there,
This topic is about my experience of configuring a-gps manually with a French operator. This may help others.
I installed a few day ago the last french official HTC ROM (see here)
My Diamond is SFR branded (French Vodafone), and after upgrading from the native SFR ROM to the HTC one, I felt a slowdown to get a good GPS signal for the apps I use: Googlemaps and iGo8. The signal also seemed less accurate.
I decided to investigate this way.
First of all, some elements that may be obvious for most of you, but reminding them does not hurt:
A-gps is a system that enhances GPS performance, by connecting to an a-gps server. As a matter of fact, this server makes use of cellular network signal to locate you faster. For further informations, see Wikipedia a-gps article.
AFAIK, a-gps is different from Quick GPS (see here) In particular, config values for a-gps and Quick GPS are located in different registry keys on Diamond.
Now let's get deeper into a-gps:
You can, once again AFAIK (and you'll correct me if I'm wrong ), use two kinds of a-gps server:
Your mobile vendor's server (i.e. HTC)
Your operator's server
I remembered that on some phones (at least Nokia N95), you have to define manually your a-gps server when using SFR network.
For Nokia, the problem is that the port used by the vendor's server is blocked by SFR WAP connection.
This is not the case of HTC a-gps server, since using HTC rom does not inhibit a-gps: it only seemed slower to me than with my SFR rom.
Here are the registry parameters for a-gps, on the original HTC ROM:
Code:
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"EnableAGPS"=dword:00000001
"ServerPort"=dword:00001C6B
"ServerIP"="10.1.101.63"
"QosPerformance"=dword:00000059
"QoSAccuracy"=dword:00000032
"TimeBetweenFixes"=dword:00000001
"NumberFixes"=dword:3B9AC9FF
"GPSMode"=dword:00000002
I guess "10.1.101.63" is the IP address of an HTC's a-gps server (?!)
I then downgraded to native SFR ROM, and here was the same key:
Code:
[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"ServerURL"="geoloc2.sfr.fr"
"GPRSConnection"="WAP SFR GPRS"
"Network"="WAP SFR GPRS"
"EnableAGPS"=dword:00000001
"EnabledPrivacyMethod"=dword:00000000
"CloseConfirmMsgTime"=dword:0000003C
"PrivacyMethod"=dword:00000000
"EnableLocInfo"=dword:00000001
"ServerPort"=dword:00001C6B
"QosPerformance"=dword:00000059
"QoSAccuracy"=dword:00000032
"TimeBetweenFixes"=dword:00000001
"NumberFixes"=dword:3B9AC9FF
"GPSMode"=dword:00000002
As you see, the server is defined with its URL, "geoloc2.sfr.fr" (known as one of SFR's a-gps servers), and some parameters are different.
Of course, you have to replace "WAP SFR GPRS" by the network connection you want to use.
I upgraded to HTC ROM again, and set the operator's rom values.
Now I've got the feeling that it's harder, better, faster, stronger (and more accurate).
By the way, QuickGPS is configured in the following key: [HKEY_LOCAL_MACHINE\Software\HTC\QuickGPS].
Note that, on SFR branded rom, this key does not even exist.
Hope this helps.
I've wondered why Quick GPS seems to replace the A-GPS feature on the diamond. QuickGPS doesn't seem to do a damn thing for me. From cold boot, I can stand in open air for 5 minutes until I even start to get a peek at a couple of satellites. How can we be sure that QuickGPS is even working at all?
I used to own a Nokia N95 that had the A-GPS feature, the GPS inside the N95 was pretty average. But with the A-GPS feature you could at least get a lock in under 10 seconds, every time. As long as you had configured your positioning server, (supl.nokia.com) and you had a data connection, then it was consistently under 10 seconds from cold boot. Without A-GPS it was more like 5 minutes plus, basically what I'm seeing on the diamond.
As people have noticed, using tools like Advanced Config to enable A-GPS breaks the GPS completely. Probably because of the missing settings such as you have outlined above, (I noticed these settings while poking around in the registry recently too). I wonder how we can find out what the server names for other countries are and get this working for eveyone.
Also, the IP address 10.1.101.63 is a private IP address so I guess that explains why it fails when you switch AGPS on, that address will never be contactable, so they must have used it for some kind of internal testing - but if it's working for you (with your new settings) then why did HTC choose to leave it broken for the other ROMS....
Well... Since I updated to this last HTC rom, QuickGPS "does work". I mean, it is an installed program, therefore available in "programs" list, and when I launch it, I can "download" data to update it. Though I don't have a cue of what use is made of this technology on Diamond.
I've always used Advanced Config to enable A-GPS, and it has always worked for me. But if it breaks the GPS, I guess you can do it from the registry by setting "EnableAGPS" value to 1.
I also tested a N95 8Go recently, and I had the same results.
But I'm not sure to understand your need: Diamond has both A-GPS and QuickGPS. I don't think QuickGPS is very efficient, but A-GPS is.
I do also think that setting the "ServerIP" value to "10.1.101.63" must work worldwide, since I bet this is HTC's a-gps server.
With this, GPS signal takes about 30 seconds to lock (at first use after soft-reseting, but may be under 10 seconds for next uses).
Did you give it a try?

Yes I have i too, and it connects and downloads data ok. But does it speed up a GPS lock? I don't think it does. I've hard reset and just run TomTom without QuickGPS and then with QuickGPS and I cannot for the life if me see any difference at all. In TomTom Satellite screen, you can see no data. If it was working, you should see all Satellite 'numbers' in their respective little boxes and then the tracking would begin almost immediately. But I'm not seeing this.

Many people have said that enabling A-GPS (via advanced config or direct reg edit) makes the GPS stop working completely i.e. never getting a lock. If you have got this working for you, as far as I know, you're one of the first! Lucky you!
But I'm not sure to understand your need: Diamond has both A-GPS and QuickGPS. I don't think QuickGPS is very efficient, but A-GPS is.

No that IP address is within a private non-routable range for internal private networks and cannot be reached from the internet. Read this if you want more info.
I do agree though on the A-GPS being better, and with my experience with Nokia phones A-GPS is excellent. I don't understand what it is that QuickGPS is trying to do, because there is nothing quick about it. I thought it would be similar to A-GPS (in how it actually works) but now I'm confused :/

Now that's the sort of time we all should expect when using an assisted/quick GPS aid to the actual GPS chip. It should be lightning fast. So to me it says QuickGPS is pretty lame, as everyone is using it by default in all ROMS and there are many many people complaining about the GPS not getting a lock at all. So it can't possibly be working properly. And if it is, it still sux.
I'm going to try and replicate those settings you have above on my Diamond and see how it goes. I'll post back shortly.
OK well I've put all those settings in, but still no luck. It is not working. I've been waiting several minutes and still cant even get a fix.
It's not out of the realms of possibility that SFR's A-GPS server can only be used by SFR customers. After all, they assign you your IP address when you connect to the web on your diamond so they could easily lock it down so that random people cannot use it. In fact that would make a lot of sense.
I think we're close, but I guess we need to find a SUPL A-GPS server that is open to the public, maybe? Or certainly at least find out if HTC has one that we can use that is accessible via the internet... Maybe someone else has some ideas?
you can try: "supl.nokia.com" instead of "geoloc2.sfr.fr"
Have you tried this, and what port does it use?
I'd been playing some more and found out having it enabled really screws things up - TomTom thinks it has a lock, then it doesn't, then it does, then it doesn't, etc. It's really bugging out. So I just switched it off.
I'm really interested to know though if A-GPS will help with the ongoing GPS-Lag/inaccuracies problem, some poeple have reported that the lag is fixed in the new OS builds floating around but I can confirm that it is not fixed - in fact it felt like it was worse!
This GPS is causing too many headaches!!!

I'm also in Australia and i'm having the exact issues as you in regards to GPS lag and inaccuracies, i do however get a fix quite quickly, first time after a ROM change it takes a while but after that its somewhere between 30 sec and 1 min 30. I have changed my rom many times updating to all the latest custom ROM's, still its inaccuracy remains, its about 40 metres off on my device. I live inhouse number 16 and yet it tells me I'm at house 20. Like WTF........
What a pain in the arse!!!!
I got ip adress of HTC aGPS server!
its the 64.14.59.165
you got to just change the htc stock server of the diamond to this and its working well for me.

Tell me about it. Mine is about 50m off 90% of the time, sometimes it looks like it might be ok. The other thing I noticed today is that the 'speedo' in TomTom i.e. the bit on the status bar that tells you how fast you're going - which is usually very accurate - still tells me I'm going 15km/h, then slowly counts down to zero anything up to 20 seconds after reaching a complete stop! I am starting to regret spending money on TomTom. But to quantify that, I don't blame THEM, I'm just pissed I've shelled out so much for the Diamond + TomTom and the fkng things dont work properly. We have to get to the bottom of this!

Yep, its all the same issues I'm having, but not just with tomtom, I'm using iGo8 and garmin XT with no success.
This was written by me on another thread complaining about the GPS.
I called HTC support Australia and informed them off its fault with GPS lag and its accuracy, I informed them that over 50% of users are having this issue on the XDA forum, they told me that no fault has been logged and there isn't an issue, It may be time to call up the tech support and make some noise to get this issue resolved. its a pain in the arse and it shouldn't be happening.
I also called up Hong Kong Customer support the other day and they said the exact same thing...... i think.... the chicks English was just deplorable.
I think i may call the Australian HTC support again, and just irritate the **** out of them, hopefully this time they may have a solution for me.

Is IgO 8 working with A-GPS enabled?
Thanks
Update/Refresh of GPS data
Maybe a stupid question, but how can I update the a-GPS data or does the device update the data automatically?
pls delete

What is the data amount when using AGPS ?
Are some data only transferred when opening TomTom ?

It should be only a few KB send, and then a little more KB received.
It should only happen when the GPS is activated (e.g. you start TomTom) and then the A-GPS would kick in then. It should not transfer any more data unless you lost the GPS signal, then it would assist the GPS in getting a lock again, and therefore transfer another few KB.
I tried everything and i am jst giving up. what can i do to make this friggin gps work? I followed everything meticulously on ppcgeeks http://forum.ppcgeeks.com/showthread.php?t=36639 without any luck. google maps keeps search for satelites, and nothing. always number is zero. do you have any idea what could be wrong? i am on telus cdma network btw.
hi friend...
1st in which area of this sad world do you live??
2nd what is your mobile operator??
3rd do you have a costant/flat umts/gprs connection trought your mobile??
bye,

i live in toronto. i had blackberry curve before this and the gps was smooooth.
this one is being alil biatch.
i am with telus
the third question i don't understand, but my blackberry curve was also with telus, for a week before diamond arrived and the gps was excellent. i don't know why diamond gps is so screwed up. as i said, my diamond is the cdma version. any help is much appriciated, thank you.
I think to know what can be... I mean that happened something similiar to me, but because I cook a new rom every week the problem has disapperead itself.
Anyway I think it can depend by an old problem relative to a dns library that can be overwritten by some software, like for ex some voip software, this cause the internal gps to stop working.
Just tell me if your gps is detected, I mean if your software (for ex tomtom) searches for sats or it says something similar to "gps not found".
If your gps is detected but the software searches sats for infinite time you must look this procedure:
I strongly suggest, just for have a fast response, to use a software like "gps tool" (download from here): go in an open space & install the cab file, then choose com4 => select "clear memory" => & finally "open", go to information window & wait for at least 5 minutes (you must be patient the 1st time), until you read: mode 2D fix... the bars go from red to green, when you have a fix press (in the 1st page) "nav init", after few seconds you can press "close" & exit the program, now open you favorite nav software & you'll get a fix in few seconds.
Instead if your gps isn't detetced you must look this procedure:
hard reset your mobile, because your dns dlls are corrupted
let me know if you have results... bye,

hey ninja, lol. how's it going
suiller thanks for the help. i am going to give that a try. i hard reset my rom. i am on juicy 2.5. but it didn't change much. do you think if your first option does not help. i should flash another rom, maybe stock rom, and then put the one i want?
it depends... like mentioned above if your GPS works it just a gps cache problem, in fact soon as cooked the gps cache is empty or corrupted, so it must be reinitialized, doing so the 1st time takes long time
instead if your gps isn't detected, you can check in a minute also by lanuching gps tool, it is yet configured to look at com4 (default com port for gps in htc brand, the problem is somewhere else, I mean that probably the problem could be also in the rom you are using, if the 1st procedure does not work, try to restore your original rom, before carrying back your mobile for warranty be sure it isn't "self-mistake" (for ex by installing an "unofficial" rom)
for what I can say I cooked almost everything & just happened one time, many months ago in my opinion 99,9% of cooked roms doesn't touch gps at all, so I sincerely didn't remember what's happened that time

hi. thanks for all the help guys.
i tried the gps tool. i installled it and selected clear memory, open, and it never stopped going through the numbers. same numbers again and again, but when i clicked setting it said mode 2 not fixed.
if i recall properly, the gps message i got from google maps was gps not found, but i am not sure ithat it's the rom's fault. it's very popular on ppc geeks. i tried qualcom method to solve the problem but it did nothing. mdata, info, is saved on my hone but no change. so i will try disabling agps, if no help i hard eefresh, or put another rom, if all faili go to fet it replaced, again.
thanks for all you support
ok, i reflashed to stock rom, tried the gps tool, it keeps showing the same method and won't stop. do i need to wait for it to stop?, cuz when i go to information it says mode 2 not fixed.
i am going to hard refresh, and put juicy 2.5 back on, and wait for your help. if nothing i will take it to the store.
I hope you don't have A-GPS cofigured...this will surely screw up your GPS
in tweak diamond, agps is enabled. when i disable it and go to quick gps, it gives me an error, when its enabled quick gps downloads.
should i disable a-gps in tweak diamond?
sure friend, AGPS should be disabled if your provider isn't able to "provide" you that service, beucase it takes busy over & over your gps chipset
there 3 modes to update gps sats positioning:
1) quickgps, simply it's a database where are stored circles/ellipses made by sats, because they are always the same, that data are predicted, so for this reason those values are good also for the near future (at max 1 week), this is the "old" method used by years to make fixing times faster, even if resulting position isn't very accurate
2) AGPS, this should be the last & most intelligent feature, of course your provider must be able to provide that data, if your provider can do this it simply compares your current position (cell broadcast) with the ones stored in their database, and provides automatically to your mobile (trought a regular gprs or umts service) updates positioning, if your provider isn't able to provide this service your gps chipset will be always busy because it scans the network continuosly and other software like for ex tomtom wont be able to access the gps chipset anymore because like told above it is busy by another application
3) classical method, I call old school, and this is also the more realistic method, even if 1st time can take very long and if you don't use very much your navi software it is very annoying because sats runs fast simply it needs a program like gps tool or gps test to full the gps cache (1st time is totally empty), where will be stored current sats position (circles/ellipses), this method can also be reached with last modern navi software, like for ex tomtom7, you must leave it runs until it finds something, remember that 1st time can take up to 20 minutes... it depends also by region & sky conditions, in general in a good environment (ex openspace) for me & in my experience it never took over 5/10 minutes
so if your provider doesn't provide AGPS service simply turn it off and re-run the 3rd method in an open space and you'll see that something will happen
anyway if trought gps tool you are able to open the com4 port and you see data flows it means that your gps chipset is recognized, you have just to wait, if you want a faster/simpler app search here around for "gps test"... simply run it, it detects automatically your gps com port & starts to discover sats
hoping to have cleared something about gps system
bye,
davide
ok, i reflashed stock telus rom, then i flashed juicy 2.5, hard reset and here i am. i got diamond tweak, disabled a-gps:
with a-gps disabled, quickpgs does not update any more. gives me an error at the end.
so i am going to do clear memory with gps tool, but does baudrate matter? when i turn it on it is set at 5600 should i change it to 4800?
do i need to be in an open area when clearing memory, or it does not matter?
if this wont work, i will go in throug hqualcom, and make sure i have the settings posted on ppc geeks forum. i hope something will turn up.
what is the connection though. if a-gps is disabled, quick gps does not download. but when its enabled it does. does it mean telus supports a-gps or it shows that there is an internal problem with my gps?
thanks for all the help.
i installed gps test. it shows yellow circle and GPS starting up. above it shows hdop 50.00 Fix 1D, and baudrate is set at 9600.
does this also take a long time, or is it a good sign. if it shows this, does it mean my gps is working, but only needs to be reconfigured somewhow?
i was just outside for 1 hour, with the gps tool turned on. nothing. it keeps clearing memory, or so it says, but when i look the same numbers show up. i waited for an hour till it got dark and cold and went back. gps test shows starting up gps but never getsa round to it either.
i duno what to do anymore.
ah, where is everyone?
holy crap, finally, i solved it.
I had the same problem after setting AGPS in Advanced Configuration Tool. Nothing I did: soft reset, hard reset even installing new ROM resolved the issue. Finally I found the problem: Go to Programs-settings-phone-services-Location setting-get settings-On. This allows your phone to tell your GPS where you are. The GPS now finds satellites in a few seconds.

it was an old habit of disabling gps to emergency only. i didn't realize it would screw me over on a pda. well. nice nice nice.
thanks for all your help everyone, you ahve been great.
this means that your mobile provider supports AGPS feature
so it must turned on... well done
First and foremost I want to say that this would not have been possible without the XDA-Developers community, especially Da_G!! So say thanks to them!!
This has been tested by me and I can confirm that it works.
I use an AT&T Fuze on US T-Mobile's network. Obviously my phone is SIM unlocked.
I recommend you use the Blackstone Radio 1.10.25.25. NOTE: You must be security unlocked to flash the Blackstone Radio or any other radio from a Device other than the Raphael.

This cab file has made it possible for me to lock onto upwards of 7 satellites each and every time in less than 20 seconds. From a cold start(after a reset) I can lock in less than 20 seconds outside. From a warm start it's more like 5-10 seconds.
Inside my bedroom with no visibility at all I can lock onto upwards of 7 satellites in about a minute.
With all that said... Here's the cab file:
WARNING!! USE ONLY ON USA T-MOBILE!! Do not use on other carrier without making the appropriate registry edits!
WARNING!!This requires a data connection so do not use if you do not have a Data Plan or are willing to pay any charges to your account. I'm not responsible if you use this cab file and get a bill in the mail for hundreds of dollars because you didn't have a data plan.
For AT&T could I just edit the carrier to "medianet" or what ever we use? along with the nokia settings ? I'll play and see what happens later today. Thanks for your contributes!
I have the same phone as you dharvey, with an AT&T fuze unlocked for T-Mobile. However, I did not hard-spl mine because I have no idea if my phone is security unlocked or not.
My GPS works just as fast (under GPS Test), and can get a lock quickly without the cab. I'm looking at the registry edits and I'm just curious if this will improve GPS capabilities on my phone. Before you did the registry edits on your phone, what was the speed of your GPS before? Did you use GPS test? Or am I too far behind on the AGPS discussion?

Yes if you just wanted to make the manual registry changes without installing the cab and use "MEdia Net" (yes capital E) and use the Nokia settings it should work. Don't see why you would want to though AT&T has their own AGPS Servers.

HardSPL does not require a security unlock. Only if you wanted to flash a non-Raphael Radio like me would you need to security unlock the phone. This cab will install for you but I can't guarantee it will work for you unless you have a similar setup to me.
The time it took for me to get a GPS lock on my phone before making the above changes was upwards of 2 minutes. Now I'm down to 10-20 seconds without the extra.bin from QuickGPS.
Also I'm not using GPS Test. I have the same results with any GPS program I use from Google Maps to TomTom to GPS Test.

That should work. Try it and report your results. Basically all you need to change is the operator connection so that it can connect to the internet.

thank you very much. testing it....
does anyone have agps working with at&t. as in you are able to be in a basement and using tomtom get your location.... im not talking about by the window and 30sec to connect. thanks
it took me almost a min from cold start (after soft reset) but only about 5-10 second after that. not bad at all considering that it used to take me upward for 3-5 mins with a lot of helps from other program (quickGPS + gpsToday) It was a bit cloudy outside, that might be the reason why it took much longer but still a huge improvement from my previous set up.. and now i don't have to start up anything else prior.
Thanks!

Nothing is going to give you position data in the basement. Nothing. AGPS? Forget it. Even if your carrier gives location data on the user plane to Tom Tom or whatever else, there is no way to get a lock underground.
I am amazed at what people expect GPS to be able do.

Especially considering the whole concept of GPS. GPS = Global Positioning System.
This is quoted directly from Wikipedia:
Basic concept of GPS
A GPS receiver calculates its position by precisely timing the signals sent by the GPS satellites high above the Earth. Each satellite continually transmits messages containing the time the message was sent, precise orbital information (the ephemeris), and the general system health and rough orbits of all GPS satellites (the almanac). The receiver measures the transit time of each message and computes the distance to each satellite. Geometric trilateration is used to combine these distances with the location of the satellites to determine the receiver's location. The position is displayed, perhaps with a moving map display or latitude and longitude; elevation information may be included. Many GPS units also show derived information such as direction and speed, calculated from position changes.

GPS needs to be able to "see" the satellites in order to lock. AGPS(from what I understand) still needs a strong cellular signal in order to work too. If you don't have a strong cellular signal then how is it supposed to triangulate your position?
Using GPS in a basement will never happen. I'm shocked I can get a lock in my bedroom to begin with.

I'll 2nd this.... If I'm kidnapped and locked in a basement or dungeon of sorts, AGPS would enable me to load TomTom and I could find out where I was locked up.
On second thought, I could just call for help on my Rafael...
some conclusions about these AGPS settings using Orange in Spain as the data connection used to communicate with the Nokia AGPS servers.
It works!
AGPS data arrives to the mobile and help the GPS, to get Fixes.
but there is one small problem, as AGPS is now enabled, it seems that the GPS SW (gps test, google maps, gpstoolpro, gpstoday, tomtom...) waits for the AGPS datat to be processed before it tries to get a direct fix with the satellites. Sometimes this can produce a delay. I mean that before, the "kick gps tools" such as gpstoolpro, gpstoday used to get really quick fixes without the AGPS settings. Tomtom used to stay really longer if it was not kicked by them. Since now that i have AGPS, Tomtom can acquire a fix very fast, but the "kick gps tools" waits really longer until they get a fix becasue they seem to wait for the AGPS data to be processed..
So it seems that the AGPS settings make tomtom get faster cold & hot fixes, but slow down the "gps kick tools" cold & hot fixes.
before AGPS settings:
cold start:
gpstoday 15 sec
gstoolpro 15 sec
gps test 1 minute
tomtom 2-3 minutes
hot start
gpstoday 6 sec
gstoolpro 6 sec
gps test 15 sec
tomtom 1 minute
after AGPS settings:
cold start:
gpstoday 20-30 sec
gstoolpro 20-30 sec
gps test 20-30 sec
tomtom 20-30 sec
hot start
gpstoday 15 sec
gstoolpro 15 sec
gps test 15 sec
tomtom 20 sec
times are aprox.
What about your experiences with these AGPS settings?

Dharvey, when you fire up google maps, are you using the "Use GPS" option for getting your location? Also, what do you have set in your "External GPS" settings? Did you put the "GPS program port" to COM4 as has always been suggested? Also, hardware port = none? Thanks for all your work on this.
Just a small note, the cab actually has a typo (and it's my fault b/c i was a little inebriated when I typed up the post containing the info, and have since edited it!)
nokia.supl.com should be supl.nokia.com
It still works because the IP address is used directly unless it fails, in which case it rolls over to the hostname. But still, fixing it now rather than whenever nokia moves the supl server to another closet and your a-gps breaks would be a good idea

Good call. I'll fix this right now.
EDIT:: Cab file fixed with Da_G's correct URL.
So would using the Nokia servers still work if you were on AT&T?

I don't see why not. As long as you change the connection type to your carriers first this way your AGPS will still connect.

Nothing is going to give you position data in the basement. Nothing. AGPS? Forget it. Even if your carrier gives location data on the user plane to Tom Tom or whatever else, there is no way to get a lock underground.
I am amazed at what people expect GPS to be able do.

@everyone - correct me if im wrong but isn't the Agps on our phone supposed to give you an approximated location whether you are connected to satellites or not?
