[Gpsbabel-misc] how to download from BlueLogger

[Vidar G. <vid...@37...>]

is it possible to download tracks directly from the
DeLorme Earthmate BlueLogger GPS using GPSBabel?


reading the documentation and the example at
http://www.gpsbabel.org/htmldoc-development/fmt_wbt.html
i would expect to use something like this,
but GPSBabel just halts for a very long time.

  gpsbabel \
    -i gpl,erase \
    -f /dev/tty.EarthmateBlueLoggerGPS--1 \
    -o gpx -F downloadedTracks.gpx

does the BlueLogger also support the "erase" keyword?


a bit related to this is: which format do i download to?
which information does the BlueLogger provide, and
which format is needed to store all of it?

using the BlueLogger Manager software from DeLorme,
i've been wondering which of the available DeLorme formats
to save my data. same problem as above really: what is
available from the GPS unit and what is stored with the
different file formats?
