PyKMaze

Abstract

Geonaute Keymaze 500/700 GPS watch devices are shipped with a Windows-only application software.

Pykmaze alleviates this issue and allows to transfer data from/to the device with any host.

Features

Pykmaze is a pure Python command-line application that does not offer a graphical interface as the original application software does, but nevertheless allows to download recorded tracks and upload waypoints.

Its produces and reads Google Earth .KML file, so that tracks and waypoints may be observed and edited with the Google Earth application.

Important notice

The Keymaze 500/700 protocol has been reverse-engineered from scratch. Pykmaze code is not based on published information and may fail to comply with the communication protocol the Keymaze device expects.

Use it at your own risk.

Supported devices

Although it seems that Keymaze 500 and 700 share the same communication protocol, no test has been run with Keymaze 700 GPS devices yet. It seems that the Geonaute device is a rebranded GlobalSat GH-615B device, so pykmaze might also be able to communicate with these devices.

Pykmaze is not compatible with earlier devices such as Keymaze 300 that may use a different communication protocol. Check out the gpsd4 project if you're looking for Keymaze 300 device support. Both projects are fully unrelated.

For now, pykmaze has been successfully run on an Intel Mac OS X Snow Leopard 64-bit host. It should run fine on any Linux host.
