thanks for the article, it's very informative. It didn't say much about whether the assistance is done via data or not but seeing as we have the gpsone chip and there's the pde ip address found under the gpsone settings, leads me to believe that we need data for aGPS. I didn't build advance config into my rom so I guess I can't change it. Do you happen to know if the advance config is the advance config(Schaps config) found in the kitchen? Do you know what it does, like does using it change the registry settings? maybe it disables assisted gps that way. I just don't want to rebuild/reflash another rom if I can just do the same thing by changing the registry as with advance config.

Your testing would suggest that the cell tower "assistance" is using a data route.
I turned off aGPS by using a program called Advanced Config. It is included in many custom roms, can be dl'd too. I also turn off my data when I go to canada by preventing data while roaming - for reasons other than just the aGPS. The only thing I've found with iGo8 is that with aGPS and data off, I typically need to soft reset before using it or it won't get a lock, don't know if this is because it is trying to use old sat info, or because I just got impatient the first couple of times and then began soft resetting after that. But yeah, I would get a lock in about 2-4 minutes with that config, and dropped sats about every 10 mins for 20 seconds or so. |
