Hello all,

First I need to confirm that a780 has built-in GPS? I bought one from ebay and it had no mention of GPS. But using SEEM file editing, I enabled GPS and now my phone shows GPS icon (may be an icon only )

Now assuming it has built-in GPS, anyone tried getting co-ordinates (latitude, longitudes) from it? I am hoping to get NMEA access to the GPS.

Thanks

what's offset did you edit, and bit did u change...

or could you upload your seem 0032-0001 to the Neostream Server...

I will post the file later.

I changed 3 bits in the SEEM_32 at:

Offset 8A

Bit index:

3 (LOCATION_AVAILABLE)
4 (LOCATION_ON_OFF)
5 (LOCATION_HELP_INFO_ON_OFF)

They were all OFF (0) changed them to ON(1)

Excellent find! Now I get a little satellite dish icon on the status bar, but it has a red slash through it.

Mine is red too. Should it be some other color?

May be it is not getting the GPS signal lock. I will try keeping it near window.

I do not want to flash the phone with Copilot firmware, unless I am sure that phone has GPS. Those of you who have programming interface done (I do not have transflsh card yet, just got my phone) can you please check if the /dev/mux(??) is there and is dumping NMEA?

Thanks

A screen capture on CCMOVE shows a grayed satellite icon rather than a solid one with a red line through it:



I don't have copilot installed now either. Here's what strace on lapisrv shows just trying to start without copilot. I attached strace after lapisrv had already been started but before the icon showed up.

hey,

Interesting lines are

open("/dev/mux14", O_RDWR|O_NONBLOCK|O_NOCTTY) = 6
write(6, "P\0\10\21\2\1\317\260", = 8
read(6, "P\0$\22\2\1\0\0\0\2\0\0\0\2\0\0\0\1\0\0\0\2\0\0\0\0\0\0\0\0\0\0\0\2\317\260", 1024) = 36


But it does not look like NMEA

Say, where did you come across this information?

On a german gps-enabled A780 I get the dish with the red slash if GPS is disabled in the status menu.
If its enable the dish is grey. When Copilot is running the dish becomes black and blinks.

Can you switch GPS on/off in the status menu? Maybe its only switched off.

You're talking about the "Device Status" panel that comes up when the status bar is tapped, right? With other options including Battery, Time, Current Network, Net ID, Antenna (on/off), GPRS (on/off), etc.? I don't get a GPS option in there at all. Searching around the libraries, it looks like libezxam has a bunch of references to what might be an option called "AGPS", is that what's in your Device Status panel? I thought it was a full-blown GPS implementation -- If it's truly assisted GPS, it's not likely to work on my side of the world...
