Build Status Coverage Status

A python library to download and upload files from ANT-FS compliant devices (Garmin products).


  • ANT
  • ANT-FS (with command pipe, file listings, downloading, uploading, etc)
  • Three libs (ant.base basic ANT library, ant.easy blocking version using ant.base, ant.fs ANT-FS library)


  • Python 2.7+
  • PyUSB > 1.0a2 (seems to be a bug which makes it segfaults on version before Alpha 2)
  • Root access (for installation only)

Automatic install

  • Install setuptools:

      apt-get install python-setuptools


    wget -O - | sudo python
  • Run the following command:

      sudo python install

This will install everything required on your active python installation.

Manual install

These should only be necessary to install manually, if you don't want to use the Automatic installation script.

  • Install PyUSB.

      pip install pyusb

    (Or alternatively from sources available on GitHub)

  • Install udev rules (Only required to avoid running the program as root).

      sudo cp resources/ant-usb-sticks.rules /etc/udev/rules.d
      sudo udevadm control --reload-rules
      sudo udevadm trigger --subsystem-match=usb --attr-match=idVendor=0fcf --action=add

Supported devices
