Description Jan Knutar (reporter) 2011-01-18 23:20:21 UTC

SOFTWARE VERSION: 
(Settings > General > About product)

5.2008.43-7

EXACT STEPS LEADING TO PROBLEM: 
(Explain in detail what you do (e.g. tap on OK) and what you see (e.g. message
Connection Failed appears))
1. 
Start agps-ui
2. 
Menu -> Info
3. 
Click "Update cache now"

EXPECTED OUTCOME: 
Cache is updated. Cache refreshed date changes to current time, acquiring gps
lock is fast(er).

ACTUAL OUTCOME: 
Cache is not refreshed. Achieving GPS lock is very difficult.


OTHER COMMENTS: 

At some point Nokia changed the supl.nokia.com to a pool of servers, based on
geodns. Some of the servers offered work with supld/supllistenerd, others do
not.

For me, supl.nokia.com (which the agps connects to) resolves to 83.150.75.211,
which does not work (as described above).

Example of a working server is 66.35.236.25.

It is unclear whether this is a bug of agps, or whether it's a server bug. In
any case, it'd be nice if things didn't suddenly stop working :-)

I have no idea who maintained and if anybody still maintains agps-ui
0.12-1beta...
Quim, any idea?

agps-ui for N810 is currently not maintained, sorry.

Comment 3 Jesper Henriksen 2011-05-23 11:56:34 UTC

Who maintains the servers then? Would it be possible to ensure that all servers
in the pool support supld/supllistenerd?

Is there a workaround so those of us affected can switch to a server that
works?

Comment 5 Jesper Henriksen 2011-05-23 12:19:08 UTC

Found a workaround myself. Gconf to the rescue :) The address supl.nokia.com is
stored at two locations in the gconf tree:

$ gconftool --get /system/osso/supl/agps_srv_address           
supl.nokia.com

$ gconftool --get /system/osso/supl/slp_address
supl.nokia.com

Can be changed to a working server:

$ gconftool --type string --set /system/osso/supl/agps_srv_address
"66.35.236.25"
$ gconftool --type string --set /system/osso/supl/slp_address "66.35.236.25"

Now agps-ui works as expected.
