InfiniTime

This is a go library for interfacing with InfiniTime firmware over BLE on Linux.

Go Reference

Importing

This library's import path is go.arsenm.dev/infinitime.

Dependencies

This library requires dbus, and bluez to function. These allow the library to use bluetooth, control media, control volume, etc.

Arch
sudo pacman -S dbus bluez --needed
Debian/Ubuntu
sudo apt install dbus bluez
Fedora
sudo dnf install dbus bluez
Features

This library currently supports the following features:

  • Notifications
  • Heart rate monitoring
  • Setting time
  • Battery level
  • Music control
  • OTA firmware upgrades
  • Navigation
Mentions

The DFU process used in this library was created with the help of siglo's source code. Specifically, this file: ble_dfu.py
