openant 1.3.1

ANT, ANT-FS and ANT+ Python Library

Features

• ANT base interface.
• ANT-FS (with command pipe, file listings, downloading, uploading, etc).
• ANT+ device profiles and base class for custom ones (openant.devices).
• Four libs:
  • openant.base basic ANT library.
  • openant.easy blocking version using openant.base.
  • openant.fs ANT-FS library.
  • openant.device ANT+ like devices.
• Command-line tool openant:
  • openant scan: Scan for nearby devices and optionally print device data.
  • openant influx: Stream device data to InfluxDB instance.

A note on ANT/ANT-FS/ANT+: this module is for development and testing of devices and not intended to be used as a reference. Refer to the thisisant.com website for full ANT documentation and ANT+ device profiles. The intention of this module is for quick R&D of ANT capable devices. In case non-obvious, this module is not an official tool.

Installation

Requirements

• Python >= 3.7
• libusb 1.0 (for pyusb)

Run pip install openant or pip install git+https://github.com/Tigge/openant#egg=openant for HEAD. A 'Pipfile' is also provided for use with pipenv.

If using on Linux, a udev rule for the Dynastream ANTUSB stick can be installed with sudo python setup.py udev_rules. Windows does not use udev_rules and therefore does not need to be installed. Follow libusb's driver installation instructions for Windows. macOS should work with just libusb installed.

ANT USB Stick

A USB stick that provides a ANT node is probably required. Here are ones made by Dynastream (Garmin):

• ANTUSB2 Stick (0fcf:1008: Dynastream Innovations, Inc.)
• ANTUSB-m Stick (0fcf:1009: Dynastream Innovations, Inc.)

See the note regarding Linux and the udev rule above to ensure the user has permission to run this module without elevated privileges.

InfluxDB CLI Tool

Requires install with [influx] (pip install openant[influx]) or influxdb-client module installed manually and InfluxDB server >= 2.0. See openant influx --help for the server setup. To quickly get a local instance running with Docker:

docker run --rm -p 8086:8086 \
      -v $PWD:/var/lib/influxdb2 \
      influxdb:latest

Navigate to 'http://localhost:8086' and setup a user/org (default org used is 'my-org'). Then setup a bucket to use (default 'my-bucket') and a API access token (Load Data > API Tokens).

Module Usage

Explore the examples in './examples', and docstrings within module code. Further documentation to be developed in './docs'.

CLI Tools

Accessed from module binary openant. Logging output can be enabled using the --logging flag.

Scan

Scan for nearby devices, for example to obtain device IDs. Can search for specific devices --device_type or all. Found devices can be saved to file with --outfile.

Example Usage

# print devices found to terminal
openant scan
# capture devices found to devices.json for use with antinflux
openant scan --outfile devices.json
# instantiate object when found so that device data is also printed
openant scan --auto_create

ANT+ to InfluxDB

Stream DeviceData from a ANT+ device to a InfluxDB instance. Useful for plotting real-time data and for post review. See openant influx --help. See the notes on installation for this tool. Refer to the InfluxDB documentation for the required flags.

Example Usage

# attach to first trainer found and push data to localhost InfluxDB
openant influx --verbose FitnessDevice
# attach to power meter with device id 12345 and push to localhost InfluxDB
openant influx --id 12345 --verbose PowerMeter
# attach to devices in 'devices.json' - allows connection to multiple devices
openant influx --config --verbose devices.json config

Supported ANT-FS Devices

Any compliant ANT-FS device should in theory work, but those specific devices have been reported as working:

• Garmin Forerunner 60
• Garmin Forerunner 405CX
• Garmin Forerunner 310XT
• Garmin Forerunner 610
• Garmin Forerunner 910XT
• Garmin FR70
• Garmin Swim
• Garmin vívoactive HR

Please let me know if you have any success with devices that are not listed here.
