Re: GPS - how to get lat lon and time from a bash script file ?
Hi all I come back after some tests. I would like to stick on bash script for several reasons (don't want to load another instance of python just to record some sound, etc.). So among your answer, I tried to use one of this line echo p | nc -w1 0 gpsd | tr -d '\r\n' | cut -d'=' -f2 But I got nothing in return. Could you please be more specific : * do I need to start gpsd first * will this work on every distribution, or do I need to change gpsd by fso-gpsd or anything else ? * how do I know I have a fix before using this line ? Thanks in advance ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

It works with anything that speaks the gpsd protocol. * how do I know I have a fix before using this line ? It will return ? when you don't have a fix I think. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: GPS - how to get lat lon and time from a bash script file ?
Hi kimaidou, on om 2008.12 do: -1 in settings turn on gps hardware -2 start gpsd (/etc/init.d/gpsd start) -3 read the gps data (gpspipe -r) To check if you have a fix, you might want to clean out the lines that have no lat/long info like this: gpspipe -r | grep GPGGA | grep -v ',,' And to get it in a human readable format you can use gpspipe -r | dd count=20 | gpsbabel -i nmea -f - -o gpx -F - Please read the man pages of gpsd, gpspipe, dd and gpsbabel, they are good starting points for learning bash scripting. For me echo p | nc -w1 0 gpsd is *not* working. Kind regards, Ed kimaidou wrote: Hi all I come back after some tests.

Re: GPS - how to get lat lon and time from a bash script file ?
Hi Kimaidou, I put some script on http://wiki.openmoko.org/wiki/User_talk:Kapiteined and start and stop gps in those scripts. And also clean the gps logs from data without a valid lat/long (thus without having a fix). Please feel free to browse trough the scripts and use whatever you like about it.

This is not bash, but python, and it need lib_pyfso_gobject import. The
good part is that it use fso-frameworkd
But I think it can help:
from lib_pyfso_gobject import *
import gtk
usage = OUsaged()
gps= OGpsd()
usage.request_resource('GPS')
def on_gps_fix(status):
print Fix status: + str(status)
def on_gps_position(fields, tstamp, lat, lon, alt):
print '-' * 10
print 'Lat: ' + str(lat)
print 'Log: ' + str(lon)
print 'Alt: ' + str(alt)
gps.connect('fix-status-changed',on_gps_fix)
gps.connect('position-changed',on_gps_position)
gtk.main()
