Garmin Usb And Perl

[+PetsAllOver]

Anone know of a set of Perl modules that will let you upload to a Garmin GPS over the USB port?

 

I've managed to collect a perl USB module, and a GPX parser, and there is a module to do Garmin-over-Serial, but no USB.

 

Any ideas?

Yeah. Don't. :-) The Garmin USB protocol is poorly documented, complicated, and finicky.

 

Here's a pertinent Perl snippet: system("gpsbabel -i gpx -f $INFILE -o garmin -F usb:")

I just did a Lightning Talk at Toronto Perl Mongers last week. The audio recording and slides will be up in the next few days at http://hew.ca/talks_audio/

 

I presented GPS::Garmin, and introduced the gang to geocaching. The module successfully retrieved some version numbers, current time, current location, via USB from my 60C. It didn't retrieve tracks or waypoints. When I find the time, I'll look into the tracks and waypoint changes required, but I don't know when.

 

Oops, I just noticed you were asking about uploading, not downloading. I haven't even considered uploading yet. All I'm looking for right now are downloading tracks (where GPSbable only downloaded a fraction of the tracks anyway.)

I started to get concerned that this is the second time today I've heard allegations of GPSBabel not doing tracks correctly, but I now see that both reports are from the same person.

 

GPSBabel will upload or download tracks from at least some Garmins. I have no problem believing there's some corner case somewhere in some specific model of the hardware that may not be handled right. (Heaven knows Garmin protocols are a pain - that's why I advised the dude above to Just Say No.) But I'd much rather stare at protocol dumps and/or work with you to fix the problem than to read repeatedly in the forums about how broken GPSBabel is.

 

In fact, since GPS::Garmin doesn't really know about USB, I wonder if you're running afoul of the broken kernel module in recnet Linux kernels that should be removed for successful USB xfers per http://www.gpsbabel.org/os/Linux_Hotplug.html
