Holux M-241 (MTK based) Binary File Format (m241-bin)

This format can...

  • read waypoints

  • read tracks

This format has the following options: csv .

The Holux m241 is a small datalogger using the MTK chipset, with a couple small differences in the binary format. In its default configuration, it can store ~100000 trackpoints with very limited data; to configure extended logging you can use the BT747 open source software bt747 Waypoint storage is possible only if "recording reason" (RCR) is enabled in the settings.

Holux GPSport 245 is a datalogger with display suitable for cycling, walking and running. It can store ~200k trackpoints with limited data. The m241 and m241-bin format is able to automatically detect GPSport 245 data and handle the differences from Holux M-241 devices. Note: GP245 does not log any quality of the position.

Use the m241 format to connect with the unit serially and m241-bin to read files saved by the device.
