Re: Nokia N900 A-GPS Not Working Anymore

I started to use the N900 again after one year, upgraded to latest cssu stable 21.2011.38-1Smaemo8 (10.06.2016) but no A-gps fix with supl.nokia.com , certificate expired ?

Re: Nokia N900 A-GPS Not Working Anymore

supl.nokia.com is dead, just like nokia itself. Change the value to:

Code:

supl.google.com

But I still can't figure out what is it all about? Mine n900 got fix under a minute everytime, with no cellular data, only gps, even when I only stick it through the window.

With google supl it's doing the same, mostly under 5 seconds.

But yes, my previous n900 had problems with fixing, no matter if cellular data was enabled. It got partially broken stick on motherboard and broken antena (After hitting the ground really hard).

Re: Nokia N900 A-GPS Not Working Anymore

dead? afaik it is NOT dead and still resolves to a valid address. On the other hand, I seem to remember N900 had problems with supl.google.com after the certificate problem was fixed for supl.nokia.com ... anyway, stopped using supl.google after supl.nokia started working again

as for the quick fixes on yours ... likely the result of ACWP and other variables (ephemeris data?). Take that N900 a long distance away, and not have a working SIM card ... and you'll probably be waiting for a fix for a long time too.

@gianko - supl.nokia.com still gives me near-instant fixes. i am on CSSU-T however, although I believe the certificate fix was incorporated in Stable as well

If I got fix when staying in one spot, then I can turn off the gsm and will have it fixed, even traveling 100km (Checked few days ago) with proper directions and so.

I'm on CSSU Stable, there is no problems with supl.google.com on this platform

I'm not sure how it is all working, but it seems that slightly different configuration works differently on many devices. For now(and for me at least), if everything is fine with hardware there is only few if non problems at all

Re: Nokia N900 A-GPS Not Working Anymore

very strange indeed. i also tried supl.google a few minutes ago, and because the gps data was mostly valid, the location was correct but 'coarse accuracy' - it didn't lock in 3 minutes. changed it back to 'supl.nokia' and as always, lock was done in less than 20s...

must be that your "it seems that slightly different configuration works differently on many devices" comment is correct, which actually sucks, haha

EDIT: have to add i did these tests indoors

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

According to this post the cert for Nokia is expired. I have no indoor fix with only wifi and A-gps. Tried both Google and Nokia supl but no fix. Btw if I ping supl.google.com I have replies but if I ping supl.nokia.com I got 100% packet lost but resolve the IP 54.93.209.220

Re: Nokia N900 A-GPS Not Working Anymore

Hi gianko, the current cert of supl.nokia.com is not expired. It has been renewed in February.
This is the bash oneliner I use to check:

Code:

/usr/bin/openssl s_client -connect supl.nokia.com:7275 2>&1 | /bin/grep -A40 BEGIN | /usr/bin/openssl x509 -noout -text | /bin/grep -i -A1 -B3 "Not After"

Works on N900 and most linux boxes.

For looking after other certificate problems see this post:
https://talk.maemo.org/showpost.php?...&postcount=101
Try the cmcli commands with your N900 and see if you get "Verified OK".
And for proper GPS-testing I suggest seeing the posts on this page:
https://talk.maemo.org/showthread.php?t=90651&page=6
and this post:
http://talk.maemo.org/showpost.php?p...5&postcount=31

I dont have any issues with GPS here currently. Using supl.nokia.com with fingers crossed ...

Anyway, glad to see some of you still using their "Apparat" here ;)
Cheers, Ulle

Re: Nokia N900 A-GPS Not Working Anymore

Hmm, noticed yesterday that I have problems with supl.nokia.com lately:

Code:

Feb  4 14:32:01 fremantle location-proxy[1297]: GLIB DEBUG default - Socket to supl.nokia.com opened, fd=12, verify_res=19

Feb  4 14:32:01 fremantle location-proxy[1297]: GLIB WARNING ** default - host: supl.nokia.com not verified, result: 19

Feb  4 14:32:01 fremantle location-proxy[1297]: GLIB WARNING ** default - Connection to h-slp.mnc002.mcc655.pub.3gppnetwork.org:7275 failed

Feb  4 14:32:01 fremantle location-proxy[1297]: GLIB WARNING ** default - error:2006A066:BIO routines:BIO_get_host_ip:bad hostname lookup

Feb  4 14:32:01 fremantle location-proxy[1297]: GLIB DEBUG default - Socket fd=12 closed on request

The device has CSSU-Thumb with openssl 0.9.8zh-1+maemo1+0m5+0cssu0

My other N900, with openssl 0.9.8zf-1+maemo1+0m5+0cssu0 gets quick fix, with exactly the same settings. Here's the log:

Code:

Feb  4 22:11:42 Nokia-N900 location-proxy[1300]: GLIB DEBUG default - Socket to supl.nokia.com opened, fd=12, verify_res=0

Feb  4 22:11:43 Nokia-N900 location-proxy[1300]: GLIB DEBUG default - Socket to supl.nokia.com opened, fd=13, verify_res=0

Feb  4 22:11:43 Nokia-N900 location-proxy[1300]: GLIB DEBUG default - Socket fd=12 closed on request

Feb  4 22:11:43 Nokia-N900 location-proxy[1300]: GLIB DEBUG default - Socket fd=13 closed on request

An interesting thing is - the 2nd N900 never tries to contact h-slp.mncXXX.mccXXX.pub.3gppnetwork.org, whereas the 2nd one does. XXX depends on the operator whose SIM is in the device

cmcli output for both N900 is the same

Code:

cmcli -T common-ca -v supl.nokia.com:7275

1ad16dd494e161abd39bd94ed94bf8eafe4ede28 supl.nokia.com

 Verification failed: self signed certificate

and with both,

Code:

openssl s_client -connect supl.nokia.com:7275 -CApath /etc/certs/common-ca/

Re: Nokia N900 A-GPS Not Working Anymore

Found the problem

Downgraded all *maemosec* packages to versions 0.1.4+0m5 (had 0.1.5 from devel), and 0.2.3 (had 0.2.7 from devel, and my 2nd N900 has 2.4, but doesn't seem to be in any repos)

Instant fix on my 1st N900 and no attempts to contact 3gppnetwork.org

Re: Nokia N900 A-GPS Not Working Anymore

Can you update *maemosec-certman-applet* back to 0.1.5 and verify if those packages are not problematic?
