Setting and reading POIs on a GPORTER GP-102 GPS device for geocaching or other purposes.
I bought GPORTER GP-102 device for geocaching. Sadly the included windows software does not allow to set POIs. So the device became pretty useless for geocaching. I wrote a simple command line application, that directly can set POIs and read them. So geocaching or google maps coordinates in decimal format can be taken.
gcc gporter.c -ogporter
sudo cp gporter /usr/bin/
You'll find a simple description in "POI-Format.ods".
On my linux machine when the GPORTER GP-102 is connected it will appear in "/media/"username"/CANMORE/GP-102". The place will be different on your machine.
I have choosen the parking place of the television tower of Stuttgart.
Google says it is on: 48.755319, 9.188723
This means N48.755319, E9.188723.
To set this POI change in the POI directory enter in a shell (bash) "cd /media/username/CANMORE/GP-102/POIs". Enter the following to set the POI 010:
gporter -N48.755319 -E9.188723 -o010
If you want to set a symbol, other than the star you can chosse between star, house, flag, car, eat, bus, gas, skyscraper, plane.
To set a house symbol on the same coordinate use the -s parameter and enter:
gporter -N48.755319 -E9.188723 -o010 -shouse
The gporter shows in its display POIS in the format xxxx-xxxx. You can set those eight digits by using the -d and -t parameter. If you want to set 5678-1234 enter:
gporter -N48.755319 -E9.188723 -o010 -shouse -d5678 -t1234
To read a coordinate enter enter in a shell (bash) "cd /media/username/CANMORE/GP-102/POIs. Type:
gporter -r 001
This may output a coordinate like:
N48.712320 E9.306870
Enter this one in google maps to see where it is.
In the folder gporter_files you'll find some test coordinates.
