Timex Data Recorder (Bodylink) and Linux


2005-03-31: Linux utility for controling the device is now available.

2005-02-22: Initial release.


mouseThis device collects information from Timex heart rate and speed+distance sensors (Bodylink system). I have bought the data recorder together with the Timex Ironman Bodylink Performance Monitor sport watch 5E671 and Navman II GPS for collecting my excersise data. As usual, the provided software is for MS Windows/Mac only.

The data recorder connects to a USB port and is recognized by Linux as an HID device (the usbhid driver). However, this kernel driver cannot control the device properly so I have written a user space Linux application timexdr for downloading data from Timex Data Recorder. The utility can be downloaded from the project's web site hosted by BerliOS.
