Using the AT Debug Log to obtain GPS commands
To be able to enable the GPS on Hermes, a couple of things still need to be researched. One of those is what kind of AT commands are being sent to the Radio ROM to properly initialize the GPS (at@startgps etc.).
On the Hermes, the AT commands (and the resulting NMEA output) can be observed using the HTC AtDbgLog feature. I'm not sure whether the Trinity has the AtDbgLog feature as well, but if it has, somebody with a Trinity should be able to capture the actual at@startgps and related commands.
I would be very grateful if somebody with a Trinity could test the following:
1. Add the following registry keys
\HKLM\Software\HTC\ATDebugLog\Enable=1 for logging
\HKLM\Software\HTC\ATDebugLog\LogMode=1 for logging into file
2. Soft reset (wait a minute or so first to be sure the changes are persisted)
3. Use the GPS with navigation software for a few minutes
and post the results from the \Temp\AtDbg0.txt logfile? (Note: the logfile should first be copied to the device before you can copy it to Windows)
It can be disabled by removing the registry keys again and soft resetting
