Cannot get a gps fix indoor
 
1 Attachment(s)
Hi,

On my both N9 and N950 I can't get a gps fix at all. I left it running for over 45 minutes. I have both options in the control panel for gps enabled. My location-settings.conf is attached. I was all the time under wlan. One device's language is English, the other's German, I'm living in Poland.

What am I doing wrong?
Thanks

Re: Cannot get a gps fix
 
I've just noticed that I have such errors in syslog
Code:
nped[2452]: i2c_write: Remote I/O error
I don't have the warranty anymore.

One of the devices was shortly reflashed

And syslog

Code:
Dec 27 21:51:28 (2013) nped[2220]: nped stopped
Dec 27 21:51:32 (2013) nped[2264]: nped started

If you phones is connected to the charger when you run gps program (Drive for example), disconnect from the charger.
If this is a case, its known problem and as far as I know, we still not have solution for this..

Well, I've disconnected the charger but still can't get the fix. I'm indoor, so I expect the WLAN positioning to get the GPS. (When using N900 as the main phone and sharing the mobile internet)

Background connections are disabled so that the device doesn't connect to the internet without my awareness.

Seems similar to this issue http://213.128.137.28/showthread.php?p=1357890
Did you try the solution on that thread:

I've tried this before, applied to both devices, fixes neither.

used devel-su to do it, and did it successfully

Re: Cannot get a gps fix
 
So you mean you have two different devices and suddenly it happens that neither can get a GPS lock??

Someone's covering your satellites, dude, have you looked upwards lately :D:D

The third one does get a fix - N900. :)

Repeat - I'm indoor and it behaves as if wlan positioning didnt work

juiceme 2013-12-29 11:14
Re: Cannot get a gps fix
 
Yes, but think of the odds, you have 2 devices that lose positionng at the same time... how can that happen?

On one device it can be a software problem, though.
But the N9 doesn't get the fix straight after reflash!

Re: Cannot get a gps fix
 
I've even set SuplForced=true and enabled background connections but still no fix indoor. (both devices)

And I remembered that N9 started to fail first, and N950 later.

/edit: gpsmeefo shows one satellite found (indoor). But the wlan positioning should work then

I tried using the gps outdoor. And I managed to get the fix.

But then getting indoor, the problem comes back. Just as if the WLAN positioning didn't work.

With the N9, i never managed to get a GPS fix indoor :o

Fortunately, outdoor was never a problem.

Re: Cannot get a gps fix indoor
 
me neither, I always thought wlan positioning was disabled on the N9

Your expectation may be too high. Getting a fix indoors is a bonus, not a right. It depends on how far you are from an external door or window. Even WLAN positioning need some weak GPS signal. It is ASSISTED GPS after all. True WLAN positioning can put you kilometers away so is practically useless.

Re: Cannot get a gps fix indoor
 
Well, one satellite is being detected indoors.
And it's the N900 that sets my expectations so high! It ALWAYS gets a fix, even while indoors!

FWIW, of all devices I tested in my living room, the N9 is the only one who never had a fix :confused: I tried several Apple products, androids ones (HTC, Samsung, Sony) and Jolla.

N9 gps is unreliable. Visited NYC and used n9 since it has offline maps but the ****ing n9 locked only once on the whole trip. Totally useless. Nokia's maps might be OK but their gps is years behind other brands.

Well, I visited Amsterdam, Paris and London and had no problem getting my N9 to lock without any data assist. Sure, it may take a couple of mins but it never failed me. Even my Android touting companions deferred to my N9 for street navigation due to Nokia's excellent offline maps. Google maps are good but only if you have data. I'm telling my story to show that the N9's GPS isn't as useless as you make it out.
