Mode 3 and 4 tells the phone to contact the PDE server which until a few days ago we didn't have.
[Mogul, XV6800 ROM Development] nitro66215:
I thought Mode 2 also was assisted.
[Mogul, XV6800 ROM Development] tbhall77:
From Shadow-tech

I believe mode 2 is suppose to lean more on the phone figuring it out and use the data gathered from either the PDE or QuickGPS on where the sats are at, but I could be wrong in understanding this. Also, just because a setting tells the phone to use a PDE sevrer doesnt mean it'll be successful if the PDE IP info is no good or there is a communication problem, so, it would fall back on being stand-alone in my mind.

More great info from Shadow.

still working!

// added after edit

Im did this to see if it would lock faster and work in hybred mode since i have unlimited data plan and a 3600mah battery. I dont care if battery runs out since i can pop in my second one.

I set to mobile instead of PDE in QPST, based on the post from linked above.

I really try not to post, due to the fact it may confuse people.//

I went for a ride with windows live map on " get current gsp pos" and reg set to mode 4. Map followed my route perfectly...

When Shadow-Tech first posted the Alltel IP and then GC posted the VZW IP I was getting anywhere from 6-10sec locks. Starting today, it's taking me now about 70sec to get a GPS lock. Not sure if it is the added load to the PDE servers or what. I've flipped my settings around along with clearing the memory in HTP's gps tool and I havent come close to getting back down under 30sec. Don't get me wrong, this is still way better then the 5-10min it use to take. Just had that taste of 6sec locks and I got it bad for wanting it back. ;)

edit: I put it back to using verizon IP, PDE mode in QPST, and GPSMODE=4. It is back down to being 5-30sec locks now. I can only assume it was from slow response from PDE server.
[Mogul, XV6800 ROM Development] deeznuts2:
Sorry, but I dont believe that.

I played around with MS Base for the last 24 hours (mobile) and it took forever to get a lock and when it did, it only fixed on 4-5 sats

I went back to MS Assisted and get a lock within 7 seconds and 8-9 sats

While battery may be better with the mobile setting, pde is by far the fastest and most reliable (IMHO)
[Mogul, XV6800 ROM Development] drellisdee:
I've found better results with the alltel PDE server on vzw than the actual vzw PDE server. After testing over a few days both of them on cold locks with HTC gps tool clearing cache and then not using the gps for 4 plus hours. The alltel PDE server works and works well on vzw with >10 second locks. The vzw server went down this morning for me as well. The best I've gotten with the vzw server is ~15 to 20 second locks with most taking about 40 seconds today after the server went back up. This is a great improvement however over the 2-5 minute locks I used to get outdoors only. My location is Charleston, SC if that matters. This is not a post meant to lessen any of the hard work put into finding the VZW PDE server just a report of my personal experience to help potentially fine tune it for us Verizon users. I used mode 4 and the respective PDE IP in the registry for both in testing.
[Mogul, XV6800 ROM Development] x51:
I would imagine load balancing is exactly it... your being sent to the least busy IP... I would also wager a guess if you reprovision again you may get another IP.

So maybe we can assume it's 8888 on all servers.

Verizon has 65,534 ips.. in this group.. Does anyone have a port scanner they can recommend that runs on wm6? I find that you must use a verizon ip to access port 8888.. So it's gotta be done from the phone. (I'm unable to connect to 8888 from any other device but my phone) I use xvutils but the port scanner does 1 ip at a time.
[Mogul, XV6800 ROM Development] serfboreds:
Post that PDE IP for Alltell please so we can test for ourselves.

[Mogul, XV6800 ROM Development] whbell:
I was thinking the same thing. Would it work for a PC tethered through a VZ connection running NMap be able to perform the scan? I might add port 7788 also, but in any case, this may work?
[Mogul, XV6800 ROM Development] gc14:
Yes, because it has done absolutely nothing for Verizon users...until now that we're using PDE.

I never said MS Assisted was better than MS Based either. I said that the battery drain is not an issue for me, so I'm using MS Assisted.

As a data point on the current function of the PDE IP address, I performed the new aGPS fix on Thurs night and found that it worked great: 8-10 sec locks with 8-10 satellites visible even indoors. Friday morning I had an issue, but it was due to a data connection problem because of poor signal reception in the locale I was visiting. Friday night, I did a PRI update using GC14's cab and instructions and updated my registry as well, with GPSMode=4. Found aGPS working great once again, with similar performance. Still working great as of this morning.
[Mogul, XV6800 ROM Development] drellisdee:
Im a VZW agent the worst I could imagine they would do would be restrict access to the PDE server with a VZ navigator provisioning check against your MDN/NAI. They rarely act on ToS breeches (I have only seen 2 of thousands of aircards canceled and both of those used in excess of 50gb a months for 3 consectutive months and were warned and did not use in compliance with ToS). If things like this bother you I would be much more concerned with unpaid tethering and not use of a PDE server IP.

I would suggest following GC's instructions and also adding the IP/port as well as setting gpsmode=4 into the registry. I tried the QPST setting "mobile" with gpsmode=2 and I was consistently getting 60min locks but they were more accurate then PDE/gpsmode=4 setting.
[Mogul, XV6800 ROM Development] rhannahs19:
yeah ive followed his instructions, now you are reccommending to go into the registry and change it to gps mode 4?
[Mogul, XV6800 ROM Development] dnchattan:
Utterly astounding..

I was not very optimistic in my test of doing it from home, where I rarely get even a single bar of signal when I'm standing by the window. I've never gotten GPS to work anywhere on my road.

I went through the instructions (very straightforward), and after resetting opened Google maps. Turning on GPS and walking towards the window, I got a lock with 5-6 satellites. It jumped around a few feet in each direction, just a little jitter- but damn accurate to boot. Within my city, I can only think of one time where I got more than 5 satellites.

Props DCD! Some damn fine work.
[Mogul, XV6800 ROM Development] aguas:
good little tip is to add in the server ip and port into the registry with mode=4. its seems to help a tad. thanks for the heads up
[Mogul, XV6800 ROM Development] tbhall77:
I started with gpsmode=4 using the Alltel IP the day before GC released the VZW IP. From my expeience, GPSmode=4 and PDE setting will get me a quick less then 30sec lock, but it isnt as accurate as mode=2/mobile. Using google maps with the sat view; the dot showing where I am is all over the place. It'll move to the front of my house, to my back yard, and to my neighbors. It's still accurate enough for me to get directions from tomtom and my other gps programs and so I am sticking to this setting for now. As for gpsmode=2 and "mobile" setting; I was constantly locking indoors at 60-70sec for me, but once it locked, google maps was pointing right to the room I was standing in and there was no moving all around.

Read all 40 pages and am confused. If have 6800 with full verizon MR1 release installed can you get this to work by unlocking with spl 2.47, flashing DCD 3.2.6, and changing qpst settings?

Had gps working but got refurb phone and for some reason decide to flash MR1. Actually so the wife would leave me alone about flashing and tweaking my phone.

Hey guy, DCD does some dam fine work, but I believe you needed to thank GC for the vast majority, if not all, of the leg work in getting this for us.....
[Mogul, XV6800 ROM Development] shadow-tech:
guys, for having figured this **** out like 3 days ago we are doing really awsome.

but keep in mind it is kinda still a work-in-progess till we get all the xda users to do some testing and give us their feedback. We dont know the optimal settings until we know.

just some more things to keep in mind.

if u have position claculation = PDE in QPST then the phone company may have more info on where u are located (for the paranoid peeps) It will also use more data because there is more communication with the PDE.

I am still working on testing out the pros and cons of the different position calculation modes (mobile or PDE) and the gpsmode regsetting (2 or 4)

If u guys want to post what mode u like better and why let us know. try and keep it simple like:

Im using:

Position Calculation = PDE (or mobile)

gpsmode = 4 (or 2)

"It locks on quicker but is less accurate" or "i dont satellite lock for 2 mins with this setting" or "work better now, fast lock and very accurate"

That way we can figure this out.

i got some pics below if u are interested in know the difference between the modes. Ill have to be in the next post cause i dont got files on this PC
[Mogul, XV6800 ROM Development] rhannahs19:
Im Using:

[Mogul, XV6800 ROM Development] kdj67f:
I like the idea of getting this stuff locked down, but it seems that I too did the QPST programming ass recommended in this thread, GC's other GPS fix a while ago and have the default suplagpsmode=2 (whatever that reg key is, I cant look at my device right now)

The gps worked awesome first day, no soft reset in between and would not lock second day. I soft reset many times, used Bafs gpstoggle, checked and unchecked the location on in settings, etc.. I switched to mode=4 and it worked again, superfast and super accurate. It just stopped working again, no locks. I soft reset, went through the same process but switched back to mode=2, soft reset and it picked up again.

I am currently on my 3rd cycle, at mode=4 and it seems to be sticking. I mean it appears to be still working after 24 hours. I will wait to see if it is my device that is haunted :D

so,

Calc: PDE

Mode: 2 and 4

When it quits, I toggle between modes and soft reset. Both seem to be the same in accuracy and speed, in my opinion. Both have provided locks within 30 seconds, both have provided warm start locks of less than 3 seconds. I gues my info here is vague, I will test some more if I have more problems.
[Mogul, XV6800 ROM Development] shadow-tech:
mode 2 and 4. lol that helps.

here are the pics i prommised.

i think i would rather have a longer initial lock and more accurate position.

forgot, in case u dont know already, it is my theory at the moment that the settings in qpst and the registry go hand in hand.

i believe that if u have position calc=mobile then u should gpsmode = 2

i belive that if u have position cal=PDE the u should have gpsmode =4
[Mogul, XV6800 ROM Development] kdj67f:
I apologize, like I said my account of this is pretty vague. I guess I dont have that many apps to really benchmark any of this. But I really could not tell the difference between the two.
[Mogul, XV6800 ROM Development] shadow-tech:
its cool man. i know how u feel. i dont notice a difference yet. but in the documentation they are pretty adamant on which mode u use.

also, in the qualcomm gpsone documentation they say that when carriers set up a PDE server they should use port 8888 or port 8889. So if u are doing ur port scanning u need only to search for these. i dont get into that stuff. but u can let us know what u find. if we got more pde servers that would be cool.

I travel to Chicago Sun so I am curious to see how it works since I could not get connected on a regular out of town. I am now concerned about turn by turn, using tt7. Using tt7 it has always been accurate on place of businesses but a few feet off on residential addresses (my wife Garmin is also off on residential addresses as well). This is true before the fix... I only trun on GPS when outside I see no need to report results from in a building...if it did not connect would not concern me..only concerned when ready to drive...

I've never in my life been able to lock inside, even when standing at my huge livingroom window overlooking half of Boston.

I don't think anyone here really knows for sure. From the first post in the link, the guy makes himself out to be a professional in gps...

I would say from the information we know that it is safe to say it wouldn't hurt to use it. I guess a test would be to try and get a lock without the ephemeris file. On my phone it is in \windows\ and named xtra.bin. I'm still on gpsmode=4... Took google maps 25sec to get a lock, but that might be because it used cell tower triangulation. Probably need more testing done.

Question for the ones who it's not wokring for or when it didn't work on Friday when people were having problems. What sat does it show it's looking for? Right now mine is only looking for one sat, #8. Curious as to if Verizon is playing games with the PDE server if anyone else is getting the same sat. but in a totally different area.

I dont think that out of 68.7 million U.S. subscribers, the people here at xda and ppcgeeks and others around the net are 'overloading' the servers or causing them to notice. they probably wont know ever. if u saw before i think it is 1/10 of 1 kilobyte that we use for this.

I never thought that us here could ever overload the servers. There was talk here about how they could check the requests for the PDE though, that's more what I was thinking.

Anyway, is anyone else having problems again with long or in my case no locks at all again? It worked great this morning, now not at all. I did nothing new to the phone since the morning.
[Mogul, XV6800 ROM Development] kdj67f:
If you have a problem with it not getting locks, try editing the HKLM/SOFTWARE/HTC/SUPL AGPS/gpsmode reg entry from whatever it is now to something else. IE, mode=2 to mode=4 or vice versa. Heck it may even work if you change it, change it back and soft reset.

I am still waiting for another hang for me to test this. I dont think it is the mode value changing that is doing the "reset" for me (the best I can describe it) I think changing the reg value and a soft reset is what made it work for me.

I probably dont make any sense so take whatever I say with a grain of salt. Everyone else here deserves praise for figuring all this stuff out. I just am not that smart when it comes to computer stuff sometimes :D
[Mogul, XV6800 ROM Development] inothome:
I returned the programing via the QPST to it's original state but left the reg edits. Restarted phone and it started cycling through the sats again. Didn't lock inside but as soon as I went outside it did.

It would seem to me that we could create our own PDE server and use this if we wanted too to send out aGPS info. Or am I missing something, not that we woud really need too if the VZN servers are working....but I don't have he data plan, infact I have a data bock on my phone, so I can't use aGPS then, unless I could access an aGPS server over wifi.

What is odd is that sometimes I can see 10 sats, but not get a lock. What is up with that? All the sats will be at north on the map in HTC GPS, then they disappear and re-apear. Anyway....I have an old handheld GPS, maybe I should do some testing with that to compare....if that device can get a lock and the phone can't then something is wrong....anyone do testing like this?
[Mogul, XV6800 ROM Development] BillThyCat:
The fact that the aGPS somehow tells the phone what satellites to look for, that makes me wonder if the PDE is also transferring a smaller ephemeris of data. Could explain why the update is only good for approx 3 hours. If this is true, then QuickGPS would not provide any benefit. Because while QuickGPS helped a little without the PDE, it could never provide your current approximate position along with the ephemeris data so it only helped once your phone was finally able to lock onto one satellite long enough to determine the name of the satellite to figure out your approximate location.

I would like to see a decent study of with and without usage, but I would be surprised if it actually provides much or any benefit anymore.

BTC
[Mogul, XV6800 ROM Development] BillThyCat:
Twice now I couldn't get a lock after a minute, I simply turned off the phone, turned it back on, and within seconds had a lock. I think if during the 3 hour window it fails to get the updated info from the PDE server that it attempts to lock without any assistance. Currently my laptops wireless isn't working, so if the phone tries to access data while syncing it fails, it's possible it attempted to download PDE info while I was plugged in, because both times it was right after I undocked it and got in my car. Just a thought, but who knows, it could just be a coincidence too.
