Canmore GT-740FL GPS Data Logger

I have tried tracking runs with phones, but strapping a big heavy phone to your arm and trying to use it in direct sunglight with sweaty fingers just did not work for me.

Good Stuff:

Bad Stuff:

Linux

Using the latest version of GPSBabel it is possible to use Linux to extract the GPS logs: 

gpsbabel -i skytraq,baud=115200 -f /dev/ttyACM0 -o gpx -F track5.gpx

Using the latest version of GPSBabel just grab todays track: 

gpsbabel -i skytraq,baud=115200 -f /dev/ttyACM0 -o gpx -F - | /DATA/LOCAL/tools/gpstrack.php today

The raw GPX logs then just need a bit of post processing to extract the desired track or waypoint.

Current config. 

gpsbabel -D 1 -i skytraq,baud=115200 -f /dev/ttyACM0

The tmin:tmax:dmin:dmax specifies the interval of the logging. It will record a new trackpoint if at least one of the following conditions would be satisfied:

Set config to 10 secs instead of 5 secs: 

gpsbabel -i skytraq,configlog=10:4294967295:0:4294967295 -f /dev/ttyACM0

Delete all logs: 

gpsbabel -i skytraq,baud=115200,erase,no-output -f /dev/ttyACM0

LEDs

The yellow is actually more of a green colour.

GPS Prune

GPS Prune can be used to find the start and end of runs. This works better than switching the device on and off.

Fitness Clouds

The GPX file can then be uploaded to the Fitness Cloud Tracker of your choice.
