[FIX] For international users with GPS issues

Whipon · Mar 17, 2011

Hello ^^.
Well, my Atrix arrived yesterday and I noticed the GPS took too long to get a lock.
Also I tested it outside and couldn't get a lock with NDrive and with Google Maps it gave me a 900 meters accuracy.
So I remembered the gps.conf file under system/etc

Here's a copy paste of the original one:

Code:

SUPL_HOST=h-slp.mnc410.mcc310.pub.3gppnetwork.org
SUPL_PORT=7275
NTP_SERVER=north-america.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin

"h-slp.mnc410.mcc310.pub.3gppnetwork.org" is the AT&T A-GPS server. It only works with AT&T. I remember this from my Captivate days, hacking jupiter.xml.

So I changed it to:

Code:

SUPL_HOST=supl.google.com
SUPL_PORT=7276

Then we have the ntp server. File is configured to North America, wich doesn't apply to me because I'm in Argentina. I changed mine to South America as follows:

Code:

NTP_SERVER=south-america.pool.ntp.org

So here's the final result:

Code:

SUPL_HOST=supl.google.com
SUPL_PORT=7276
NTP_SERVER=south-america.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin

If you're not in South America, you can search for your respective ntp server HERE.

Now my gps is working perfectly.

gracias che, i will test this (Venezuela) and see how it goes

bl0wf1sh · Mar 17, 2011

Thanks man! did not even know that was the problem... will see if it works better now.
Though I have to say, editing with vi on the phone is a bit of a *****

Need to remount the /system partition to edit this file, btw.

I used Root Explorer to edit the file. Worked like a charm.

Anyone try using the random server that ntp.org offers? As someone who travels frequently I don't want to have to change this every time.

Edit:

My Atrix came w/o an SD card. Bought a class 4 16GB one. That gives me a total of 28GB for media (the remainder is for apps and system, fixed). I find 16GB has the better price point, 32GB is more than twice as expensive.

Note: there is a directory /mnt/sdcard/ that refers to the internal storage. If you pop in an actual miniSD card, it is mounted under /mnt/sdcard-ext/

Hey, i tried this, after it was kinda slow to find gps outdoors. I still dont get any real gps lock indoors, which is rather disappointing since my almsot 3 years old nokia 6220 classic, found them immediately being in the same spot =/

Where are you located?. It helped me greatly here in Argentina.
Don't know why yours don't work.

you need to switch on wifi/mobile tower location. It worked like a charm after I switched that back on.

Hehe welcome fellow Atrix owner in Singapore... thought I was the only one

anyways using ntp.org's asia server, works for me.

I'm recieving the Atrix here in Argentina next week as well. How did u unlock it? With cellunlock.net? Didn't you have any WiFi problems?

BTW thanks for the GPS hack. I'll do it as soon as i get mine (after rooting it).

I bought mine unlocked.
I heard lots of people unlocked theirs with cellunlock.
I don't have any bugs, besides the multitouch one.

lukexk · Mar 21, 2011

I've got mine last week.
Unlocked with cellunlock with no problem. The only weird stuff is that they sent me a set of 3 numbers. I've unlocked the phone with the first number, no idea what's the other 2 numbers for.
I've got no problem with the GPS it locks pretty fast in outdoors.
But I have the annoying notification bug, the whole motoblur mail client works pretty bad, at least with exchange.
I'm not sure if the WiFi bug is happening to me, but I don't know how to test for it either.
Another thing I've noticed is that I have very low signal in HSDPA and it swtichs to EDGE a lot... dunno if it is a configuration issue or a carrier problem.
