[Q] A-GPS in maniac's CM7
I start this thread as I would like to find out how it works and why I have a problem with it.
A-GPS in maniac's built CM7 nightly 20120616 seemed to me a great feature in case we have no data connection and need GPS.
It downloads lto.dat file to /data/location/
All other files, like gpsdata.nvs for ephemeries, LEARN_STORE.bin for last fixes, location.cfg are updated after each use of the GPS.
What I checked earlier with CM 7.2 official, with no data connection, it took ca 3 minutes for the fix (and it does not use lto.dat file)
With data connection for both builds it is only ca 10 s to fix.
But with no data connection and after downloading lto.dat file my defy with CM7 nightly 20120616 cannot fix at all - it shows up to 2 sattelites in the center of the radar, with almost the same position.
So my question would be: if there is no data connection is the device somehow forced to use lto.dat? Could be that lto.dat file somehow 'fools' the device for any reason?
