ITD

InfiniTime Daemon

itd is a daemon that uses my infinitime library to interact with the PineTime running InfiniTime.

status-badge itd-git AUR package itd-bin AUR package


Features

  • Notification relay
  • Notification transliteration
  • Call Notifications (ModemManager)
  • Music control
  • Get info from watch (HRM, Battery level, Firmware version, Motion)
  • Set current time
  • Control socket
  • Firmware upgrades
  • Weather
  • BLE Filesystem
  • Navigation (PureMaps)

Installation

Since ITD 0.0.7, packages are built and uploaded whenever a new release is created.

Arch Linux

Use the itd-bin or itd-git AUR packages.

Debian/Ubuntu

  • Go to the latest release and download the .deb package for your CPU architecture. You can find your architecture by running uname -m in the terminal.
  • Run sudo apt install <package>, replacing <package> with the path to the downloaded file. Note: relative paths must begin with ./.
  • Example: sudo apt install ~/Downloads/itd-0.0.7-linux-aarch64.deb

Fedora

  • Go to the latest release and download the .rpm package for your CPU architecture. You can find your architecture by running uname -m in the terminal.
  • Run sudo dnf install <package>, replacing <package> with the path to the downloaded file.
  • Example: sudo dnf install ~/Downloads/itd-0.0.7-linux-aarch64.rpm

Alpine (and postmarketOS)

  • Go to the latest release and download the .apk package for your CPU architecture. You can find your architecture by running uname -m in the terminal.
  • Run sudo apk add --allow-untrusted <package>, replacing <package> with the path to the downloaded file.
  • Example: sudo apk add --allow-untrusted ~/Downloads/itd-0.0.7-linux-aarch64.apk

Note: --allow-untrusted is required because ITD isn't part of a repository, and therefore is not signed.


itctl

This daemon comes with a binary called itctl which uses the socket to control the daemon from the command line. As such, it can be scripted using bash.

This is the itctl usage screen:

NAME:
   itctl - A new cli application

USAGE:
   itctl [global options] command [command options] [arguments...]

COMMANDS:
   help            Display help screen for a command
   resources, res  Handle InfiniTime resource loading
   filesystem, fs  Perform filesystem operations on the PineTime
   firmware, fw    Manage InfiniTime firmware
   get             Get information from InfiniTime
   notify          Send notification to InfiniTime
   set             Set information on InfiniTime
   update, upd     Update information on InfiniTime
   watch           Watch a value for changes

GLOBAL OPTIONS:
   --socket-path value, -s value  Path to itd socket (default: "/tmp/itd/socket")

itgui

In cmd/itgui, there is a gui frontend to the socket of itd. It uses the Fyne library for Go.

Easy Installation

The easiest way to install itgui is to use my other project, LURE. LURE will only work if your package manager is apt, dnf, yum, zypper, pacman, or apk.

Instructions:

  1. Install LURE. This can be done with the following command: curl https://www.arsenm.dev/lure.sh | bash.
  2. Check to make sure LURE is properly installed by running lure ref.
  3. Run lure in itgui. This process may take a while as it will compile itgui from source and package it for your distro.
  4. Once the process is complete, you should be able to open and use itgui like any other app.

Compilation

Before compiling, certain prerequisites must be installed. These are listed on the following page: https://developer.fyne.io/started/#prerequisites

It can be compiled by running:

go build ./cmd/itgui

Cross-compilation

Due to the use of OpenGL, cross-compilation of itgui isn't as simple as that of itd and itctl. The following guide from the Fyne website should work for itgui: https://developer.fyne.io/started/cross-compiling.

Installation

To install, install the go compiler and make. Usually, go is provided by a package either named go or golang, and make is usually provided by make. The go compiler must be version 1.17 or newer for various new reflect features.

To install, run

make && sudo make install

Socket

This daemon creates a UNIX socket at /tmp/itd/socket. It allows you to directly control the daemon and, by extension, the connected watch.

The socket uses the DRPC library for requests. The code generated by this framework is located in internal/rpc

The API description is located in the internal/rpc/itd.proto file.


Starting

To start the daemon, run the following without root:

systemctl --user start itd

To autostart on login, run:

systemctl --user enable itd

Cross compiling

To cross compile, simply set the go environment variables. For example, for PinePhone, use:

make GOOS=linux GOARCH=arm64

This will compile itd and itctl for Linux aarch64 which is what runs on the PinePhone. This daemon only runs on Linux due to the library's dependencies (dbus, and bluez specifically).


Configuration

This daemon places a config file at /etc/itd.toml. This is the global config. itd will also look for a config at ~/.config/itd.toml.

Most of the time, the daemon does not need to be restarted for config changes to take effect.
