From Openmoko

Hello,

Thanks to a tremendous amount of hard work by many people, we have ready a release of gllin, the GPS drives. Here is how you can get it:

1. Visit http://3rdparty.downloads.openmoko.org/

Enter the gllin directory and accept the EULA

2. Download and install gllin_1.0+r350-r0_fic-gta01.ipk to Neo, something like:

   scp  gllin_1.0+r350-r0_fic-gta01.ipk root@192.168.0.202:/tmp/
   ssh root@192.168.0.202
   cd /tmp
   ipkg install gllin_1.0\+r350-r0_fic-gta01.ipk

3. On Neo:

   cd /home/root/gllin
   ./gllin

4. In another shell,

   cat /tmp/nmeaP

you should see the NMEA data coming in now, something like this:

$GPGGA,235946.99,,,,,00,00,5.0,,M,0.0001999,M,0.0020199,*57 $GPRMC,235946.99,V,,,,,,,120180,,,N*78 $GPGSA,A,1,,,,,,,,,,,,,11.2,5.0,10.0*36 $PGLOR,IGR,81.2,7,71397,0,1*02 $GPGGA,235946.99,,,,,00,00,5.0,,M,0.0001999,M,0.0020199,*57 $GPRMC,235946.99,V,,,,,,,120180,,,N*78 $GPGSA,A,1,,,,,,,,,,,,,11.2,5.0,10.0*36 $GPGGA,235946.99,,,,,00,00,5.0,,M,0.0001999,M,0.0020199,*57

After a while you should get a fix, and then it looks like this:

$GPGGA,194851.00,3746.451804,N,12230.144387,W,1,04,0.5,029.0,M,0.053001,M,0.0090515,*50 $GPRMC,194851.00,A,3746.451804,N,12230.144387,W,000.0,300.0,291107,,,A*46 $GPGSV,2,1,07,04,60,088,32,09,59,256,21,02,54,168,34,12,38,310,33*78 $GPGSV,2,2,07,17,25,056,,05,21,306,,28,08,110,*4D $GPGSA,A,3,02,04,09,12,,,,,,,,,1.1,0.5,1.0*3A $PGLOR,FIX,1.0,ST,U,NS,A,DR,N,PS,A*2A

Note that the GPGSA line changed from A,1 to A,3. That shows that you now have a fix.

Your location will be in the first line (GPGGA). In the sample above, I'm at

   37 degrees 46.451804 minutes North
   122 degrees 30.144387 minutes west

Which is correct for me.

Have fun!

Regards, Michael

A little question

Why gllin is a "proprietary driver"? Why EULA restricts in that way our rights?
