Logging with the Blumax 4044

The Blumax 4044 is a GPS logger with which I intend to contribute to OpenStreetmap during my next visit to Georgia, where I hold the callsign 4L9MH.

This page serves as public memory on how I interact with it using Linux (very recent Ubuntu , kernel 3.0.0-14-generic).

1 Install the client program

There is a good commandline client for Ubuntu and other linux derivates calles mtkbabel

sudo apt-get install mtkbabel

It will also install missing dependencies such as the PERL module to handle serial connections.

2 Read tracks

Read out tracks, store them in a converted format with the following command:

mtkbabel -p /dev/ttyACM0 -f 2011-12-13_gpsdata -t -w

which will produce the following files:

2011-12-13_gpsdata.bin
2011-12-13_gpsdata_wpt.gpx
2011-12-13_gpsdata_trk.gpx

3 Erase the Blumax memory

It is possible to erase all the existing positions with the following command:

mtkbabel -p /dev/ttyACM0 -E
