Re: Nokia N900 A-GPS Not Working Anymore

Bump... Any workaround on this ?

Re: Nokia N900 A-GPS Not Working Anymore

Just found this thread. GPS has taken 5 mins to lock on, or so long I got bored.Tried changing from nokia to google. It locked on straight away or near as damn it. 3Ireland, 2g, GPSjinni, n900.

Thanks.

I'm not a superhero though.

Just tried it again after this post. It's hard to work out but it's seconds.

If you read in.this thread about position caching you might forgive my doubts about your report.

Yes, ACWP uses the supl server or it should. Yours is an interesting and surprising result provided that it followed a reboot. I get nothing usable (no reset just following a reboot) - generic country or nothing at all - and that is why I suggested ACWP over AGNSS as a test as it relies on a position server alone.
Any obvious reason re ISP (wifi/gprs?) as to why Vodafone might allow you to use the service?

Using ACWP method following a reboot?

supl.vodafone.com gives me another location than google used to, also more stable and always the same place when I'm stationary (home, work, ...)

I should switch back to google to see if it works too.

My ISP is MobileVikings, which uses Base as network, which is family of KPN, not related to Vodafone AFAIK.

EDIT: switched to supl.google.com + reboot -> got only center of country as location. Switched back to supl.vodafone.com and location is back close to where I am (<400m)

Excellent, I am convinced. But why vodafone works for you and not some/many others is a mystery. Some agreement between providers? If you can try with another ISP over wifi. I want you to fail
:p

Why didn't I think of that... I'll switch to wifi and check things out :)

Re: Nokia N900 A-GPS Not Working Anymore

supl.vodafone.com also worked via wifi, ISP = telenet.be

Learned some things, though: clearing the location stored in system.nokia.location does not clear the caching, only a reboot helped.

To test, I've hacked one of the old update scripts to only use ACWP and only print results, not try to update latitude or whatever... - script attached.

so, in short:
supl.google.com + wifi or 2G: mode 1 location, center of country
supl.vodafone.com + wifi or 2G: mode 2 location, accuracy 188m
