[Om2008.9] hints and results about using GPS on/with FR
Hello, In the last days (nights :-)) I did some tests with GPS on my FR and here are the results in compact form; HIH matthias ... 12. GPS Install the following packages: # opkg install gpsd # opkg install http://www.tangogps.org/downloads/tangogps_0.9.3-r1_armv4t.ipk # opkg install openmoko-agpsui # opkg install gpsdcontrol_0.3_all.opk The last one (gpsdcontrol) removes the starting of the 'gpsd' from the boot run-level, which is a good idea at all for saving power; One must edit the /etc/default/gpsd to point it to the correct serial device of the GSM antenna: # vi /etc/default/gpsd GPS_DEV="/dev/ttySAC1" gpsdcontrol as well powers on the GSM antenna by writing '1' to the drivers file; you could do this as well (and you should if you don't use gpsdcontrol) in the gpsd start script /etc/init.d/gpsd in the start/stop sequence, writing '1' on start and '0' on stop; echo 1 > /sys/class/i2c-adapter/i2c-0/0-0073/neo1973-pm-gps.0/pwron in any case you must correct a bug in the /etc/init.d/gpsd which tries to kill the gpsd, but kills to the running script itself; change: killall gpsd by: pgrep -x gpsd | grep -v "$$" | xargs -r kill The installed tool openmoko-agpsui allows you to check if your GSM antenna and chip work fine; some notes about this, GSM and TTFF: - openmoko-agpsui does not need the 'gpsd' to be started and it goes out of the way if some application (like tangoGPS) instructs the 'gpsd' to read the GSM chip; - the internal radio antenna of the GSM chip is in the upper part of the Freerunner, above the loudspeaker; while waiting for TTFF (Time To First Fix) use the FR in upright position (and with nothing above it, no building, no trees, no hand or other parts of your body); - I managed TTFF between 23 seconds and 400 seconds which is good enough if you keep in mind the small antenna; the Wiki explains about TTFF for cold start (and the FR do this) about ~15 minutes: http://en.wikipedia.org/wiki/Time_to_first_fix - in the 'SS' menu of the openmoko-agpsui you can check after TTFF very good the number of the satellites and the strength of their signals; any value greater then -145 dbm should be fine; I normally manage average values around -130 dbm; - I normally use openmoko-agpsui to get the First Fix and after this I start the gpsd and tangoGPS which find the GSM chip already well located on earth; - some screenshoots of openmoko-agpsui can be seen here: http://www.unixarea.de/GPS-test01.jpg http://www.unixarea.de/GPS-test02.jpg http://www.unixarea.de/GPS-test03.jpg http://www.unixarea.de/GPS-test04.jpg Some notes about tangoGPS: - my cached maps are now stored in the SD card: # mkdir /media/card/osm # rm -rf OSM # ln -s /media/card/osm OSM - I pre-fetched maps with some tool from http://www.millions.ca/~stacy/osmtiles.tgz which let me define the two points of a rectangle, generate the URL's of OpenStreetMap and fetch down the *.png files which I store below /media/card/osm where tangoGPS will pick them up; see the README of the tar-ball for more details; for example the complete city of Munich inside the Highway-Ring A99 are some 3000 files for zoom level 11-16 and occupy only ~32 MByte; - I run tangoGPS as well in my FreeBSD laptops and connect it to the 'gpsd' which runs on the Freerunner, i.e. using the Freerunner as the GSM device for my laptop; this give you better view to the maps with tangoGPS, of course :-) more information: Wiki: http://wiki.openmoko.org/wiki/Neo_FreeRunner_GPS ... -- Matthias Apitz Manager Technical Support - OCLC GmbH Gruenwalder Weg 28g - 82041 Oberhaching - Germany t +49-89-61308 351 - f +49-89-61308 399 - m +49-170-4527211 e <[EMAIL PROTECTED]> - w http://www.oclc.org/ http://www.UnixArea.de/ b http://gurucubano.blogspot.com/ A computer is like an air conditioner, it stops working when you open Windows Una computadora es como aire acondicionado, deja de funcionar si abres Windows ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
