Hey all, just wanted to share a tweek that I found somewhere (not for diamond) that helped me out with my aqusition problems.

HKEY_LOCAL_MACHINE/Software/HTC/SUPL AGPS/

EnableAGPS = 1
GPSMode = 4

dont know what exactly it does but it fixed all of my getting a lock problems. (dont forget to update your QuickGPS with the latest data also)

The only thing I want to see fixed now is the horrible update delay that you get when you are walking, still havent seen any solutions. From my point of view it talkes about 30~40 second of walking time before the position "catched up" to you, then it work quite well for as long as you are walking and stop only for a few second, if you stop for longer it seem to go back into what ever mode it is in from start so another wait for it to catch up.

I am doing all this is OziExplorerCE. Tested it on Googlemaps as well, works fine but the follow delay is there too.

D.

GPSMode = 1 means Autonomous (Self Fix no Assistance Required, Pessimistic Approach, Very Slow but Very Accurate)
GPSMode = 2 means Assisted by Server (Less Optimistic, Somewhat Slow but Medium Accuracy Quality)
GPSMode = 4 means Assisted by Server with Extended Ephemeris (Very Optimistic, But Sometime we loose Accuracy Quality)

can you let us know what's the other setting on your SUPL AGPS? such as ServerIP, ServerPort as well as other setting. These attributes are crucial to get AGPS works.. Thanks in advace.

I'd guess that AGPS is Assisted GPS and it can also be activated using the Advanced Config Tool (http://forum.xda-developers.com/showthread.php?t=418151)

HKLM\Software\HTC\SUPL AGPS\GPSMode 00000001 REG_DWORD

This alone above registry key is the only tweak i've made, and it fixes pedestrian mode, great for caching! :eek: Thanks a lot!! i'm happy now :D
