Nokia N900 A-GPS Not Working Anymore

[freemangordon]

ok, I made some tests with supl-client (http://www.tajuma.com/supl/) and I think I am getting near - supl.nokia.com returns almanac even not requested, while supl.google.com does not return it unless requested.

That might explain why is "ssl_read_data: SSL_ERROR=5, ret=0, errno: Success" error spit - location proxy expects almanac, but server closes the connection. I will setup supl-proxy when I have some time, to see what request location-proxy sends to the supl server.

EDIT:
If someone wants to take it from here, I will publish the pre-compiled binaries on my webserver

Hi freemangordon, thanks for looking into supl-proxy from tajuma.

Using the supl-client tool is one relatively easy way for showing that google an sonyericsson respond differently to SUPL requests (compared to nokia and vodafone). And thats the reason why some servers dont work with Maemo/N900 and others do work - if there are no cert issues. Other operation system obviously don't have that limitations for the responded data and work with all of the mentioned servers.

Deploying supl-proxy as a real MITM is a bit more advanced, my results for this are in this earlier post
http://talk.maemo.org/showpost.php?p...&postcount=101
(see attached zip there for logs) and
http://talk.maemo.org/showpost.php?p...&postcount=114

May be you (or anyone else) are able to extend the supl-proxy source code to make it work as kind of a service, i.e. so it doesn't stop after each connection?
That would make it possible to use it as a private proxy without any certificate trouble (maybe even locally on N900).

Unfortunately I can't do it by myself with reasonable effort.

I uploaded supl (supl-client, supl-proxy, ...) for fremantle to extras-devel for those who want to use it on device.

I did some more (intensive) tests (during lunch time/walk under clear sky).
And I am sure N9 and google's supl do like it each other.

Rebooted, no data connection, no fix within 30 seconds.
Rebooted, GPRS data connection, got fix within a few seconds,
And to be on the safe side:
Rebooted again, no data connection, again no fix within 30 seconds.

How did you change the supl server on Harmattan? Unlike on the N900, I couldn't find an option to configure it anywhere. I even grepped through a recursive listing of the gconf tree but I still couldn't find it.

It took longer than expected, but since today I get a new certificate for supl.nokia.com

Hope to see you all here again in a year!
With Neo900 of course <wish>,running Maemo</wish>

And A-GPS is working again on N900 (and older Symbians)!
Even there is a slef-signed cert error in the chain.

For sure. About Neo, we will see...


--edit
Offtopic question:
Any chance or contact for activating the navigation license on N95 once more? That one did not fall under the lifetime free navigation promise and it needed a 10€-fee each year paid by CC inside the navigation app itself.
MS? na.
Nokia? not anymore
Here?

Does anyone else seem to have lost A-GPS from supl.nokia.com once again, or is it just me?

UPDATE:- Its working now? I opened GPSdata app and it locked on immiediately. Prior to that both camera geolocate and Ovi maps would not get a lock no matter what I tried? Bizarre

oh. pinging today supl.nokia.com is working again. few days before supl.nokia.com was not responding

Yeah, I tested it with a ping, when playing around, so I knew there was something there. Just wouldnt work for some reason until I used the gpsapp.
