How to get data off Garmin etrex in Linux

fudokai · 2009-04-02 11:41:54

I got a Garmin etrex and a serial -> USB connector off eBay a while ago to do some mapping in Crete.

I'm trying to find out how to get the data off the GPS using Linux and I'm somewhat stuck and googling is not helping ATM

Basically the device seems to connect as /dev/ttyUSB0 - I ran a 'tail -f /var/log/messages' and, although it shows a bundle of error messages to do with plasma, does say it's connected as ttyUSB0 and launches gpsd.

I've tried running QLandkarte but it always comes up with an error trying to access /dev/tty0.

What I need now is some way of accessing the device and right now I don't know where to go next so any info anyone can give me will be gratefully received.

gpsbabel is the way to go...

remember to kill/shutdown gpsd and similar programs first.

so it looks like it's connected

l /dev/ttyUSB0
crw-rw---- 1 root uucp 188, 0 Apr 3 17:18 /dev/ttyUSB0

as root
gpsbabel -i garmin -f usb: -o gpx -F waypoints.gpx
Found no Garmin USB devices.

I tried killing off gpsd and running gpsbabel again as you suggested but with the same result.

The GPSbabel mailinglist is probably the best place to ask for more help.

If you are using a USB serial adapter, then the Garmin will be connected on /dev/ttyUSB0, not usb:. So try running gpsbabel with this.
gpsbabel -i garmin -f /dev/ttyUSB0 -o gpx -F waypoints.gpx

Beat me to it

I tried /dev/ttyUSB0 out of sheer curiosity - the web page says use usb: for all usb devices and lo and behold! it worked

Now all I have to do is convince the thing to give me access to /dev/ttyUSB0 as a user rather than root.

Just add your user to the uucp group.
