Waypoints File Format

To use the navigation feature of your varduino variometer, a waypoint file must be present at the root of the sd card. The file must be named waypoint.wpt

Waypoints are imported at boot time. Your variometer will route you in the order they are listed in the file.

The waypoint file must comply to the Oziexplorer format and can be created and modified in Varduino Manager or from other sources.

Oziexplorer files are respecting the following format:

  • The first 4 lines are reserved and should be as in the picture.
  • From line 5, one waypoint per line:
    • Field 1: Waypoint number
    • Field 2: waypoint name (max 8 char)
    • Field 3/4: latitude and longitude in decimal degrees
    • Field 7: always 1
    • Field 15: Altitude in Feet

No other fields are imported or used by Varduino Manager and Varduino variometers.

Creation and modification of Ozi files in Varduino Manager

To create or edit Ozi files in Varduino Manager, go the waypoint tab:

  • If needed, import a file by clicking "Import file"
  • To add a waypoint, fill in all the boxes (waypoint name, gpc coordinates and altitude in meters) and click "Append WP". The WP is appended to the table.
  • To modify the waypoint order, click a row and click "Move up", "Move down" or "Delete"

Once the table is populated and the waypoints are in the correct order, click "Export Waypoints". Name the file "waypoint.wpt and save it on the SD card.
