Greetings all,
I am an old Nortel NI engineer working in a Verizon switch room. My specialty is the Nortel CDMA platform, including the data equipment as well. I sit in a room where a toy cell provides a super signal so I am ideally suited to test this stuff. Mostly I am working on the dreaded data drop problem that we are having with the 3.27 radio, and so far I am finding that there is a problem, but not too bad and I am not finished gathering data. The device I will log into on a slow night is called the RNC, which is the box that controls, connects, and administers to the DOMs at the sites. So far I find that running 3.27 and SelectRadio I do get random dropps and reconnects, however with Resco Pocket Radio I do not seem to have the drops at all, well at least for the last 30 minutes that I have been listening to it. SelectRadio would drop sometimes in 1 minute and sometimes in 3 minutes but would never go over 4 minutes and sometimes would not be able to get going on its own. Resco is not at 32 minutes and not a drop or glitch. I am not sure why as i have not logged into the RNC to monitor what is happening with the session, but either Resco pre-buffers a lot farther ahead, which would make the connection outage come back before you run out of data, or perhaps Resco keeps the session alive by constantly pushing traffig up the reverse link, like an internet 'keep alive' program and SelectRadio may not do this, allowing the session to go 'dormant' state. This is very possible scenario as the dormant state is valid and a means of bandwidth management. If the system does not see a handshake within a certain time, triggered by the mobile as set by a timer value in the radio, it will put the mobile in a dormant session state. What I will do when I get some time is launch WMWIFIRouter and hook to my laptop or just teather with ICS and ping Yahoo for a very long period of time, or perhaps run a net keep alive on the laptop and stream XM thru it and see if it dies.
Anyone running Resco Pocket Radio out there getting better results than they do with SelectRadio ?????
I will keep this thread up until I get a log from the RNC and we will know what exactly is happening, but I vote for a timer value getting altered in the new Radio build that is giving trouble.
Umm, have Verizon task you to find the problem?
If so, what will you do to fix it? If not, is there any way for you to modify a radio driver as it exist now without have access to source code? Why would they modify any setting that already work fine by just upgrade to Rev.A and GPS?
Now, when I run the 3.27 radio, maybe 1 time in 50 time I have perfect connection to my VPN in Japan. There is no trouble at all on that occurrence. I can stay connect for hours. BUT, 49 times out of 50, I will be random disconnect every 3 or 4 minutes, sometimes as short as 20 seconds. If I got lucky by the 1 in 50 chance, I will have no trouble. So, how can it be "timer" issue? I think that it may be an incompatibility with the network and the EVDO Rev.A that is brought in by the 3.27 driver. If nothing else change but sometimes the data connection works fine, then obviously something else is happening.
I have never use 3.27 radio on non WinMo 6.1 ROM and I have also never use WinMo 6.1 on 1.40 or 1.47 radio either. Couldn't this be a WinMo 6.1 issue as well?
The bottom line is, 3.27 radio driver and random disconnects are correlated, but what is the cause? It may be any number of things, please check it and tell us the result, like you said - if you can.
Thanks,
Hiromitsu
More data and a file to examine
Attached is a log from the DOM/RNC connection between my unit and the network and what is going on. Someone else please feel free to offer any analysis you would care to but it looks like with SelectRadio running here is what happens: The session never dies even when the audio skips and SelectRadio re-connects, but what happens is that the PPP session (RN session) breaks and gets renewed, the session stays and does not go dormant. When it finally gets the 'tuner error' the PPP dropps and does not recover, and the session goes dormant. The interesting thing is that clicking another channel or launching any other program brings the session out of dormant and renews the PPP connection. Resco Pocket Radio never dies for me, and I can tether to my PC either with cable or Wi-Fi and ping yahoo.com until the battery dies and never skip a beat. I am thinking that a parm in the new radio ROM has been tweaked either for power management or for making REV-A or GPS work better and maybe they did not realize that it would effect the streaming media like it has, and as I said Resco does not crap out but SelectRadio does very badly. I am not finished yet, but I would like to get a ping utility, ftp, telnet, both client and daemons for my device so maybe I can run a long ping to somewhere while running SelectRadio to see if that helps. So anyone out there have this stuff ????? i will be looking and test more and attach more logs when I get these. Keep Moving Forward.
More data
I am useing SelectRadio and Resco Pocket Radio in the unit as test software. Listening to SelectRadio tab is Radioio channel 70's Rock 128kbps, and it drops like a rock regularly. I am now teathered with WMWIFIrouter 0.95 and on the Radioio web page and streaming the same channel on my PC for the last 30 minutes without so much as a skip. Useing NetPerSec to monitor the connection shows 136.1k average download and 3.9 k average upload speed, so I am leaning towards a compatibility issue between the SelectRadio app not keeping the network alive. This as I have said before might be a trim of a timer or a power management change in the ROM or radio ROM. Just more food for thought. Anyone feel free to chime in with results or ways for me to persue this.
And No I only work for Verizon in the switchroom, I was not tasked by them to look into this, it is a personal quest.
Perhaps this is whats holding up the sprint rom. If this is so,then its good news,as it implies that it may be fixed in the final release.
results from tonight, interesting
Greetings all,
Tonight sitting in the switchroom I loaded up VxUTIL and started pinging yahoo.com 99999999 times once per second and launched SelectRadio on the usual station aand got some interesting results. First, the pings went flawlessly and never missed a ping, SelectRadio dropped out as usual 2 or 3 times then got the 'tuner error' message as usual, but as I said the ping never skipped a beat nor in the network did the PPP session fall down. Resco Pocket Radio clicks along without ever skipping as usual with or without the pinging going on. Next test is for me to find the URL for the channel I am testing with in SelectRadio and get it imported into Resco Pocket Radio and see what happens. Anyone know how to get the URL for Radioio channels ??????? I will find this and post back.
Maybe try to load on your PC in WinAMP or something, then examine the .pls file?
One way to find the URL is to use the Titan's WIFI, and run tcpdump or equivalent on the wireless router or one connected to it. Assuming you have that capability.
Also, maybe your fancy CDMA gear has an option like that.
Did it and very interesting
Heres some more food for thought. I got the URL and loaded it up in Resco and played it at the same time as SelectRadio and though there was a time shift between the streams, each could be heard at the same time. Anoying, yes. Revealing, yes. The same stream stayed up in Resco but dropped out and reconnected and eventually got tuner error in SelectRadio as Resco clicked right along. So although the bad performance of SelectRadio is related to the REV-A radio and ROM upgrade, it is a problem with SelectRadio and how it handles a stream differently from Resco that makes it a problem. It is important to note that the actual data session and PPP stay up and will not drop as long as the net is kept alive. The dormant state was caused by SelectRadio dropping the connection, as opposed to the connection dropping and halting SelectRadio.
When I go in tonight during the maintenance window I will turn off the REV-A on the toy cell and see if the problem with SelectRadio stays or goes.
I don't mean to play devils advocate or be the ass here cuz i'm sure you're working hard....but from what i can see....all that you've proven is that there's an issue with SelectRadio dropping the connection. That is all well and good for people who care about streaming radio on their phone because they'll all make sure to use resco, but that still does absolutely nothing for the tons of people out there ready to punch a hole in their wall because their connection craps out while on aim, or surfing the web, or using their slingbox. Luckily, my connection doesn't drop all that often, every once in a while, but I've read countless other posts with people losing their connection quite frequently while using many other programs that use the data network.
Actually you are helping

This is what I am looking for, some feedback from others on the issue as I work on it here because I thought that my experience with SelectRadio was an example and good test platform for the problem. From what you are saying perhaps I am not having the same problem, or maybe not as extreme, as those complaining about it. Sort of like those who said their bluetooth quit after flashing this ROM, or their WiFi, or some other stuff, when none of that stuff broke in mine. Maybe I do not have this problem either so am spinning my wheels as far as helping those who do. So then if tell me what program is dropping in your case and I will load it up in mine and see if I can duplicate it in mine, if Slingplayer then I would need a server to log into as I do not have one myself. If anyone is near where I am and having the problem then I can log into the RNC here while you are on the network and do a data audit to see whats happening. Another thing is do a ##debug and watch particularly if the session goes dormant or if it goes null when the data loss is perceived, as this will help too. Thanks and keep those comming as I do aim to help and have the network at my disposal and all the diagnostic tools it posseses to figure this out.
Well, For me it's using the FTP over at PPC geeks.... Goto their site while tethering to your laptop, and try to download any ROM or the Kaiser OEM file(it's like 90megs). One time it hung at 9 megabytes, I restarted it, hung at 9 again, did that like 5 straight times.... A second time, it hung at 16.0 megs, 6 straight tries..... weird..... On a few occasions, it actually got the whole file.....
I think downloading large files is a really good consistent test to see flaws in the radio.
You speak of resco... Have you tried running the resco update utility? Any time I would run that to download an update on 3.27 radio it would ALWAYS freeze and pretty much require a reboot.
Also, to comment on the wm6.1 thing someone said previously... dcd just released 1.7.0 rom that works with 1.40 radio and I've been using it with 0 data problems/drops. There is def a problem with the 3.27 radio and I don't think it's related to wm6.1...
I'm using the "stock" leaked rom with the 3.27 radio and I have the problem too.
Yes, WM6.1 is no problem. It is problem by 3.27 radio for sure.
Try to make a virtual private network connection across ocean, and you will have big trouble by 3.27 radio. Next, my american friend tell me he can't play online game with 3.27 radio for disconnect randomly and major LAG. So, if you want a good "test" maybe try online game or VPN.
Goodluck!

Hi all , just got an Ameo (U.K T-Mobile version) and upgraded to Windows Mobile 6 Professional CE OS 5.2.1620 (Build 18125.0.4.2) official rom.
Everything works fine except GPS signal that really sucks!! I have red all topics carefully and i have set all parameters right such as COM 5 and baud 9600 but with Destinator 7 it does not fix satellite signal! It gets one satellite on cold start after 3-5 minutes and maybe some 2nd or 3rd but really UNSTABLE...so it loses fix and again from start.. Navigation is almost impossible!
Any suggestions please?Does someone else have the same problem maybe?..Or my device is faulty?Is it possible that Destinator 7 does not work fine with the built in GPS?I have tried external bluetooth gps on other port and baud and it goes fine!!6 satellites minimum 8-9 maximum and fast fix even on cold start.Is it possible that my ROM version is problematic?
ROM Version: 2.35.110.4
ROM Date : 10/09/07
Radio Version: 1.50.00.00
Protocol version: 32.83.7020.20H
I can never get a fix when it's in the faux-leather case, if that's any help... usually get a fix within 30s out of the case.

Have you tried the reg change to enable GPS in Camera mode (to allow location metadata to be stored within the picture)? I find if the GPS is ever slow to start up, using this first of all to get a location seems to kick things into life. Also make sure your QuickGPS file is upto date.
For some reason mine is now getting a lock much quicker than ever it has been before. I normally start TT just before I set off and previously it was taking approximatly a mile of driving before getting a lock. Now, it only takes about 1/2 a mile - have the US done something to the signal, or has my Ameo now developed supercow powers?
I'm running the cooked rom v3, radio 1.5 and its in the leather wallet.
Crumbs - half a mile? I usually start CoPilot when i get in the car and by the time I've started moving i have a fix - I take it out f the case to put in my Brodit mount but even in the house in the case it doesn't take that long to get a fix!
It is TomTom !!!
giorgosp: Yes, I can conform the problem and it's driving me mad!
Flashed to the T-Mo ROM this week, as PK3 was giving problems connecting to WMDC (tried a hard reset initially, and no better )
The T-Mo ROM is good, and allows WMDC to connect well, but since flashing, I've been unable to obtain a valid GPS lock. Tried with GPSInfo and iGO2006. I get a couple of small bars, and nothing more. Today, I drove for 45minutes, and no lock at all. My Orbit2 sitting on the car seat with CPL got a lock in 20 seconds from cold.
Previously, I could get a lock within 2 minutes if stationary, and about 10 minutes if moving (I live in a region with lots of windy country lanes, so rarely see the same bit of sy for more than a few seconds!), so this does seem to be an issue with the T-Mo radio.
..and further to the above, I've just downgraded the Radio to V1.47 (which means hard reset), and taken both the Orbit 2 and the Ameo outside- Orbit2 got a full fix in 30 seconds, and Ameo 30 seconds later (so 1min TTFF from cold, which is the best I've yet seen!)
Don't know if going back to radio 1.50 will keep the improvement, but I'm tempted to keep it as it is
im running 1.50 in a pawell rom and it's all good !! I think T-mo have messed things up !
So NeilM do you suggest me to downgrade radio version to 1.47?how many satellites is reaching to fix? ..to get a valid signal i think at least 4 and stable,right?
To all of you using other than the official t-mobile 2.35 rom with radio 1.50: how many sat signals do you achieve to fix using athena with the leather case under normal condition? does the radio version impact on gps signal so much?
I tried reverting to radio V1.50 and same problem, so at least in my Ameo there is a problem with the new T-Mo ROM, Radio 1.50 and the GPS receiver.
Went back to 1.47, and this morning got a cold TTFF in 1 minute.
You need 3 satelites for a 2D fix- locates at ground level, and 4 for a 3D fix, which includes altitude.
From a cold boot, the 1st sat signal takes a while, but it then provides almanac info for any other in its vicinity. As the reciver gets more almanac info it builds a picture of the sky, then the ephemeral data is downloaded.
Once almanac info is obtained, you will see the short bars in GPS apps; once ephemeris is obtained the bars turn dark, or change colour and when you have 3 of those, navigation can commence.
I can't advise you to change the radio version, especially as it needs a hard reset, but can only repeat that it worked for me, here in East Anglia, using the Ameo on Orange.
Neilm,when reverted to radio 1.50 have you used the t-mobile rom or have you used only the radio cab provided by forum?even if my question seems silly i was thinking that maybe a file of those included in t-mobiles 2.35 rom radio 1.50 is problematic??so have you flashed only the radio version back to 1.50 or the entire rom (including t-mob radio 1.50)?
So you suggest change to 1.47?i understand that hard reset is unpleasant setup from beginning but having a dead gps after paying so much for this device is worse.. Could some expert please find this issue..?
..guys i live in rome and i tried everything..it gets 1 sat fix after 3 minutes and upon gets a second one it looses both of them..my ameo is like without gps.. only when i use an external bt i-blue i can use it.. but i bought this mobile for not carrying 200 things with me.. :-(
I used the Radio only link, not the whoe T-Mo ROM, so it seems, for me at least, that it is the radio version, rather than where it comes from.
If you don't mind doing a hard rest, I'd say try it I can't say it will work, because it seems there are a number of factors which I don't understand. Some users have GPS working OK with this ROM and radio 1.50.
My personal experience is that radio 1.47 works much better for me, both for GPS and WiFi, and the phone reception is no worse. Battery use seems about the same.
Are you in Rome city centre? If so, have you tried going to a more open space to get a 1st fix? High density buildings can give a poor view of the sky, and give some 'multipath' interference, which can prevent a proper fix.
Athena GPS Quickconnect can't find anything else vaguely apprnnect
Firstly, sorry to hijack this thread, but I couldn't find anything else appropriate.
Relevant to this thread: I have no problems with my current hard/firm/software combo and GPS connect time. It is about 2-3 mins without a current quickconnect file, but fine with both TomTom 6 and VisualGPSce.
Does anyone know what the antenna hardware is like for the GPS radio in Athena? Is it inbuilt to the semiconductor hardware or is there something else? If there is a physical antenna it could be broken? Try attaching an external bluetooth/USB receiver or external antenna. If one works it can only be the antenna or the GPS hardware at fault, right?
My problem
GPS quick connect will no longer connect through 802.11 wifi, bluetooth activesync or USB activesync. The only thing to have changed is that I briefly enabled and then disabled GPRS wifi. Although the settings for GPRS/WAP have been disabled and in network settings the option for 'programs that use the internet automatically' is set to 'my work network', GPSquickconnect still seems to be using my GPRS service provider (which cannot be deleted).
I know a hard reset will resolve this but it would be nice to know if anyone else has come across this and found a reg tweak to remove the service providers in the drop down connections list.
Thanks is advance.
I'm just posting because lately I've discovered a pretty nice little trick for our beloved bittersweet GPS.
As most of you know, sometimes the GPS likes to think for itself and decide whether it wants to lock sats quickly or painfully slowly. Same goes for me, sometimes I get a lock within seconds, sometimes it takes 5-10 minutes (all the time using GPSViewer to cold start it first).
Well, for the past week I've been using WiFiFoFum while I'm driving to track AP's while using the GPS function to log long. and lat. and collect them into a merged kml file for Google Earth. When I first enabled the GPS function in WiFiFoFum, I noticed that I got a fix and lock almost instantaneously, not even using GPSViewer (my GPS had not been used for at least over 24 hours). I thought it was probably a fluke and shrugged it off, but sure enough the next day I go to use it and BAM another lock within 5 seconds, again no GPSViewer. I've been doing this now for 7 days straight, and each day is the same thing, very quick fixes and locks. I don't know what is going on in the background, but screw GPSViewer, I'm using this from now on to start my GPS.
As always though YMMV, but I'd like to get some feedback if people decide to try it.
Cheers.
I would have to agree on this find and praise for you on how much faster than gpsveiwer is. Iv only gotten the chance to use a few time but got a fix within 30sec of opening
I will try this today and let everyone know if I have the same findings.
Can anyone recommend some good gps software for off road and topo maps?
Thanks,
Mr.ellsworth
actually been using wififofum to grab a lock since the day i got my gps working. it helps that im a wardriver too but definitely the same results here. wififofum grabs locks quickly and accurately. i usually let it run in the background while i start up nav4all or googlemaps.

I too am a fellow wardriver...though I don't use the titan for my 'official' wardriving escapades lol.
I like to take it old school with my orinoco pcmcia w/ external antenna connected to a parabolic dish mounted on my roof. Gentoo laptop with kismet configured to use festival, with sound routed through my car speakers...
Getting all worked up just talking about it...lol
you setup makes my humble titan weep. in all honesty, i have a hard time giving up the usability and ease of wififofum. that software is just awesome. i use kismac on my macbook when im running it off of my computer but i just cant get over how easy it is to just use wififofum. cant wait until someone figures out how to enable the gps in out titans to work over bluetooth so we can hook those up to our comps
Try this... http://forum.ppcgeeks.com/showthread.php?t=21248&highlight=gps+toggle
Oh yeah... I think AmazeGPS will be good once they make it for windows mobile 6. Right now they have a BETA version. http://amazegps.com/welcome.php

Hey there, I just installed this on my xv6800 and it doesn't get any locks on sats with gps on. What should the settings be? I have them on Com4 and 4800 baud?
My results
I used TomTom 6 for a month or so and started it with GPSviewer and have the same results, sometimes it locks fast, sometimes grabs a bunch of sats but drops them before it gets a chance to lock and will keep this up seems like forever. I loaded up Garmin Mobile XT last night and find that it will start the GPS and lock within 5 seconds every time. This was amazing to me so I have tried everything to get it to NOT do it that well and I can not get it to fail.

give it time.
i have had days at a time, where i "can't get it to fail" but then once in a while it just gets annoyed with me and is buggy for a day or two. today being one of those days. i can get it to work, with soft resets and patience, but some days no matter what i do, it always works within a minute
GPSViewer can get buggy if you switch the tabs at the bottom more than once. The second tab will stop updating (you can tell this when the time freezes) and it will look like you haven't locked anything, when you actually have. Go back and forth to refresh it again.
Guys...this thread wasn't supposed to be about GPSViewer...the whole point of the thread was to do away with it.
To the guy who's having slow results with GPSViewer:
Read my OP and try and get a fix WITHOUT starting GPSViewer. So far every day for the past 9 days I've tried it, it's been quick and flawless.
Also, I don't think I mentioned it, but make sure wifi is on and you're actually "scanning" with wififofum (with the gps option enabled)...don't just open wififofum and enable gps without actually scanning.
Yup WiFiFoFum works great.
Before I wouldn't be able to lock a Satellite connection @ work ( inside a two story building, elevator, everything that would make the signal weak ) with Tom Tom using any other GPS starter program.
With this it gave me a connection in about 5 seconds. Not only that but I can use it to find Rouge WiFi connections at work.
I should also point out....once Wififofum locks the sats, you don't have to keep it open. You can close it and turn off wifi, then use your GPS software of choice.

I could never get GPS to work reliably with GPSViewer or google maps, etc....rarely it works, most of the time it doesn't, and WiFoFum is no different. It states GPS: NoFix (0) for me, outside, clear day, following everything here, wifi on, scanning, etc...
There is no magik here that makes your titan work with this program when it doesn't work with others.

Mine started working instantly all of a sudden when using this program, when it would take a while with other programs. Did it ever occur to you sir that you may have a defective GPSOne chipset in your device? Or perhaps maybe you have it set up wrong? I love your negativity though!
I've benn having issues with the Garmin Mobile XT... I have now the Sprint 3.56.651 ROM AND 3.42.30 RADIO...
when I run Garmin it automatically detects satellites without any other GPS aplication (GPSProxy, GPSGate o others...) but it only locks 3 satellites and it doesn't give me my position...
Is there something i'm doing wrong?? what do I need to get this thing working???
The big answer that you have not provided is if any other application returns the same GPS performance. Garmin, as others, only receives the data as provided by the GPSOne chipset, and I cannot see any reason why it could cripple that data.
Try again with a diagnostic app such as VisualGPSce. What you describe sounds like a rather common problem with the Titan in that it is seeing a few satellites but fails to lock-on to them and that is why you cannot determine your position. In a clearing outside, wait up to a half hour.. Try GC's QPST GPS hack.. Etc.. Garmin is unlikely to be the issue.
all right...
I already did the GPS Hack with QPST... I already waited for like 2 hours (I was washing my car) and it did lock up to 6 satellites but it still didn't give me my position...
I installed GPSProxy, GPSGate and many others but I have problems on that applications... first it doesn't show me any satellite, after 10-15 seconds it shows me like 10-15 satellites on the screen but only for a second or so and then they disappear again... this happens in a loop, it shows me the 10-15 satellites for a second, it waits for 10-15 seconds and then it shows them on the screen again for a second..........
I'm going to try VisualGPSce to see if I have any luck... i'll keep you posted...
I am running latest radio and dcd's rom with Garmin Mobile XT on VZW with the GPS Hack with QPST and get locks within 30 secs and 7 to 9 sats.
Not sure if that helps or not.
what radio are you runing?? i have 3.42.30
I don't understand what everyone is doing. I am running Garmin Mobile XT myself, and have been for a couple of months. With the Newest radio rom, and DCD 3.2, I have no problems locking sats. Normally when I start the program, by the time it's up and running, I have a lock on enough sats to get the bars all green. It's just that fast. Not sure what your doing wrong.
I run Garmin Mobile XT with absolutely no problems on VZW.
P.S. I still prime with HTC GPS Tool prior to opening Garmin.
ok still no luck...
are you selecting the GPS on Garmin as COM4:COM4: or as GPS Intermediate Driver??
GPS Intermediate Driver
Working Great
using Baf's GPS toggler cooked into 19588 rom set to standalone in registry
meaning no assisted gps radio 3.42.30. Locks in less than a minute while inside house. Using Garmin Mobile XT.

I don't understand what everyone is doing. I am running Garmin Mobile XT myself, and have been for a couple of months. With the Newest radio rom, and DCD 3.2, I have no problems locking sats. ... It's just that fast. Not sure what your doing wrong.

Careful in rushing to blame user error. Some Titans -- regardless of software settings -- just cannot match the GPS performance of other Titans. I've witnessed this myself with two Titans side-by-side. Sadly, it can be a luck of the draw...
The repeating loop of flipping back and forth between the same sets of satellites often occurs when the chipset is stuck in standby mode, so a resolution is to soft-reset the Titan. nelsongruebr's description of satellite "locks" are probably not locks but basic reception of the visible satellites before a lock - if ever - is attained. The description here of poor performance is very similar to what had stumped me on some Titans... Sadly, there may be no resolution.
I've been running Garmin Mobile for about a month on no2chem's 5067 rom and I have not had problems. I don't have to do anything other than open Garmin and within 30 seconds, I have a lock. At first, I was using the 3.39.10 radio and now I'm using 3.42.30.
so basically maybe my Titan can never be used for GPS? or maybe doing a hard reset or flashing another ROM?
Today I tried to get a lock by letting the GPS Intermediate Driver search for satellites on Garmin Mobile XT for quiet some time and had no luck... it could not even find one single satellite...
On the other hand, when I activated the COM4:COM4: it find 3 satellites, it locked to them but didn't give me a fix or a position...
I installed GPSVisualce... First it did find some satellites, like seven of them but after a couple of seconds it loose them... but I checked the coordinates that it marked and they were pretty close to where I was... so maybe it is user problem... maybe I'm missing something...
So I bring up these new questions:
What version of Garmin Mobile XT are you using?
Is somebody with the same ROM and RADIO having the same problem? (Sprint 3.56.651.0 Radio 3.42.30)
Should I flash another ROM?
thanks!!!
You need to prime the GPS first before running Garmin.
Prime it with HTC GPS Tool or GPSViewer. Once it locks, close the primer and open Garmin. Go into settings and Disable COM4:COM4, then click GPS Intermediate Driver, then click Enable.
Your problem should not be the ROM, Radio, or Garmin XT. Keep playing around with VisualGPSce as it's quick and easy to configure to use the appropriate port and will give you an easy reference as to how many satellites are seen and the number of those that a lock is made on.
Beyond that and attempting GC's QPTS GPS edit, place the blame on your hardware. The description you've given on your Titan seeing some satellites, possibly locking, and then losing then is all too familiar to what I've experienced with another Titan. You're not alone.
Problem solved!!!!
yesterday I hard reset my device and after that just installed VisualGPSce and Garmin Mobile Xt so I can try it without any other software...
I went to my house and right where I was about to go to sleep I put my Titan on his Charging cradle and open VisualGPSce and then opened Garmin Mobile XT and leave it there on my night stand all night... to my surprise when I woke up it had a lock on 7 satellites!!!! on my nighstand!!!
I supposed it needed to get a lock for some time since I'm in Venezuela and I supose it was going to be harder to lock from anther country than to lock in the US...
Thanks to everyone who posted here and tried to helped me!!!!
Excellent! Yes, when the cell network assistance feature of AGPS isn't available, for some reason the chipset on our Titans can take quite a while to download the satellite ephemeris data directly from the satellites. Though I think that you're one of the first who's recorded it requiring more than a half hour!
hehe!! i'll say more than 5 hours, cause when I saw the time data on Garmin it said that the stopped time was only like an hour and a half, so it took mora than 5 hours to get that lock...
But I think I spoke to early, yesterday when I got out of work I wanted to try to get a lock to see how long it takes, but to my surprise it didn't locked on any satellites!! not even one!! I left it again overnight and nothing!! so I'm back to zero :'(
I'll be informing you how it behaves today...

I am a newbie here but as a computer engineer I totally agree. We buy many PCs, scanners, printers, etc. all of the same brand. I can have several of the exact same items on the bench and so will not do as the identical sister/brother unit will do. My theory as a tech has been Bubba went to work mad at his wife and said what the hell I am going to just throw this crap together. Then on the flip side you have the new guy wanting to make a good impression and he spends 2 hours on one product where he should have gotten out four in that same two hours...
I think it depends on the device as well...just luck of the purchase...
ok, i kinda figure out what was the problem...
As I told you before, I live in Caracas, Venezuela... and recently the government decided to change the hour (yeah I know... What the hell where they thinking) from GMT -4.00 Caracas, La Paz, to GMT -4.30 Caracas... so Microsoft created a Patch to add the new Time Zone for Caracas... I have been installing this patch for about a year now without a problem (i had previously a HTC Touch and a HTC Excalibur) without any problems... So i instal it on my Titan and thats it...
To my surprise when i did a hard reset to delete everything and installed only Garmin Mobile and VirtualGPSce tha GPS work flawlessly... I said Great!!! It work's!!! so I installed the aplications that I normally have on my Titan INCLUDING the Patch for the New Timezone, and here is where the fun begins... the GPS stop working!!!! I didn't know it was the Time Zone patch until i performed another Hard Reset and Installed only a few aplications and the GPS kept working perfectly...
Today I'm going to install ALL the aplications that I use except the Patch to see if that does the trick...
I'll be posting tonight to tell you how it goes...
Hi everyone. Per the advice of others, I decided to make the leap and go with the Galaxy. The results have been......mixed. The main gripe is with what follows, which should seriously make those of you who haven't bought one yet, rethink about your decision. Also, this seems to be a common problem. I posted my gripe on Android forum, so I'm just copy the post:
"Hey guys. So, I just picked up the G2 and its cool for the most part but i have a pretty big problem. I live in japan, so I'm forced to ride the trains a lot. This means going under lots of underground tunnels. This is where the problem lies. Whenever I go under a tunnel and ,ofcourse lose 3g reception, when I come out and 3G reception comes back, my download connection doesn't. In other words, even though I have a 3g signal again, NOTHING WORKS. Email, browsing, anything requiring a connection stops working, just times out. In fact, under the 3G bar at the top of the screen, I can notice that the down arrow (which I assume means downstream) doesnt light up at all. The only way to get data working again is to reset the 3g connection. So, basically, everytime I lose reception and then get it back (which is about every minute or so on the train!) , I'm forced to reset the connection. This is such a pain in the *** I can't even begin to tell you..."
That posts sums it up. If you go here: h-t-t-p://androidforums.c-o-m/samsung-galaxy-s2/361794-3g-doesnt-work-after-regaining-signal.h-t-m-l
you will see other people with the same problem. Considering some of us go through tunnels every minute or so in Tokyo, having to reset the phone everytime after losing reception is a definite dealbreaker. Samsung confirmed that it was just "just part of the phone and maybe they'll have a fix in the future.
Do you guys know of ANY fix for this?
Surely I'm not alone in this issue? I've read others are experiencing the same...
Do you guys understand the problem? Should I film it or something to make it easier to understand?
How did u manage to set ur SGS2 to only using 3G??

I'm not sure what you mean...
If you're asking how to set the Galaxy for "3G Only" mode, just go to "Settings", "Wireless and Network", "Mobile Networks", and "Network Mode" and then set it for how you like.
Doesn't help my problem though...
Hi, you are not alone. I have this problem all the time as I commute too. I ride the Bart train system in the San Francisco bay area, which also goes in and out of underground tunnels, and I often have trouble regaining signal coming out of the tunnel. The tell-tale sign is the blinking or lit "up arrow" in the 3G icon in the status bar, but the "down arrow" doesn't light up. The data connection seems to just hang.
However, I do not believe this is a Samsung specific issue; I have had this problem with every single Android handset I've used.
On the Galaxy S2 however, I found out disabling fast dormancy seems to lessen this issue. That isn't to say it doesn't happen ever again...just doesn't seem to occur as often. I am able to make this assessment because I use the di.fm application on my phone during my entire commute, and after awhile I become keen to when/where my stream drops and when it resumes regularly. With fast dormancy off, I notice that my stream has a significantly higher uptime.
I don't know the science behind it, but I suggest giving it a shot. Dial *#*#9900#*#* on your phone and hit the button to disable fast dormancy. This is suppose to negatively impact battery life, but I haven't really noticed a difference to be honest.
Not even god could solve this problem. I'm sure if he did come up with a fix, samsung would give him another equally anoying problem
Yes this is the notorious "packet data hanging" issue with 3g/4g.
My SGS2 suffers from it but not all the time I go underground or in tunnels.
I think some people reported disabling fast dormancy helps, and some reported flashing back the original KE2 modem file helps.

your best bet is to download anycut and place a shortcut on your homescreen to the "Phone Info" activity. You can easily turn off your cell radio and turn it back on from there, without having to root your phone.
I believe this problem affects every phone, but some users are more prone to notice it than others due to their usage habits. It happens on E/3G/H/+. And in all cases, if you give it enough time, it will fix itself every time. You can visibly see this by keeping an eye on your phone's data symbol whenever you experience this problem. You will see it disappear for a second, then reappear and your data connection will resume.
I believe this is a problem with the phone not realizing that it is out of range of a connection point, and continues to try to negotiate with it. The reason some people do not seem to be affected by this problem is because even though someone is standing in the same spot, they may be connected to different nodes. You can check these out in the Phone Info screen shortcut created with anycut--note the CIDs whenever your data hangs. I have noted several problematic CIDs I encounter regularly on my commute route. CIDs seem to be location based, and while my data doesn't necessarily hang each time I connect with a "problematic" CID, whenever it does hang in a certain geographical area, it is connected to a problematic CID in that area. The point is that even a problematic node will not always cause your data to hang, but when your data hangs, it will always be the same CIDs.
That is what makes this so aggravating. It is almost impossible to reproduce this problem at will. Which means there just isn't a way for us to gauge the effectiveness of any "fix". There is no way to establish a control group because we cannot force our phone to connect to certain nodes; it switches on its own.
I don't know how many more times my desk will survive due to me banging my head against it...
It's a long story which I will cut short; we have bought a large number of cheap handsets (Nuu A3L, spec sheet here: https://www.devicespecifications.com/en/model/4fc6428b ) and they're using Sygic truck as their navigation tool.
We straight away ran into some major issues, the main one being with Sygic/GPS. The devices would begin navigating but would then start to lose GPS signal and start bouncing around, sometimes they would recover (only to do the same thing again a few minutes later) and other times they would just lose GPS connectivity entirely and would lock up for 10+ minutes.
After seeing how poorly the application ran on these devices I had a hunch that the application was hogging every last drop of available system resource. I removed as much bloat from the application as possible, I turned off the 3D map (2D is much more fluid), turned off all POI, turned off traffic updates etc and it appeared to resolve the issue. I drove for 30 minutes with two devices side-by-side, the default one continued with its horrid GPS loss while the customised one worked fine.
A few people have taken these out today to test, but are apparently having the same issues regardless of the changes that I made.
I'm now at a loss and struggling to work out what else can be done to help. They're running Airwatch and we can push remote changes out at any time, so I am at the mercy of those more knowledgeable than I (you).
If anybody has a decent suggestion then you win a free balloon.

Let me be clear that I never played with sygix enough to speak directly about it. You may have already tried the things I'm brainstorming here.
I'm not clear as to why you didn't just load a different mapping app on these? There certainly are a lot of them.
What level of connectivity are they using? If you are on GSM or 3G, downloading map information as the vehicle moves around, that could slow things down to a crawl. Using an app that doesn't have to work this way could be a solution.
I noticed that the phone has a 500ish MHz clock speed and just 1 GB of RAM. As you've discovered, every layer of complexity in the mapping will slow it down further.
Something like Tom-tom was written to run on a lot less hardware. That's the kind of thing that I'd look for. I believe that Here is also made for very low end hardware.
Not sure if it helps, but at least it's a path worth looking at.
