怎么上手

由 README 提炼，执行前请确认
原文 
从 Releases 页面下载最新 APK 并安装到 Android 设备
硬件要求按 README 说明

README 未说明具体硬件要求；需 Android 设备，使用 LoRa 需外接 RNode 硬件，BLE 可与 Android 及 Linux 设备互通

Android 上的 Reticulum 原生消息与语音应用，不依赖互联网、基站或中心服务器即可通信

基于 Reticulum 和 LXMF 协议的原生 Android 通信应用，可通过蓝牙 LE、TCP 或 LoRa 组网，在无网络环境下实现离线、隐私优先的消息传递。

核心能力

  • 通过 LXMF 在 Reticulum 网络上收发消息
  • 支持 LXST 语音通话
  • 经 BLE、WiFi、TCP 或 RNode LoRa 接入网络
  • 端到端加密，无账号、无追踪、无中心服务器
  • 支持离线地图、位置共享与 NomadNet 浏览

容易踩的坑

需自行从 GitHub Releases 下载 APK 安装，未上架应用商店；使用 LoRa 需额外准备 RNode 硬件；从 Sideband 等其他 Reticulum 客户端迁移身份需手动导入

内容由模型根据 README 生成，可能不完整或不准确，以官方文档为准。看原文 README

    Columba 2.3.4-beta

    Installation

    Pick a backend, then download the APK matching your device's CPU architecture.

    • Python backend, RECOMMENDED — ships Mark Qvist's official python reference implementations of Reticulum and LXMF via Chaquopy.
    • Kotlin backend — ships Torlando's EXPERIMENTAL, AI-GENERATED native reticulum-kt / lxmf-kt / lxst-kt stack.

    The python version is highly recommended. The kotlin version is a work in progress, and is not yet verified to be completely safe. The kotlin version may yield better battery life depending on your device, and comes in a smaller apk due to not requiring a python runtime.

Sentry collects stack traces when Columba encounters errors and provides helpful information to the developer to improve Columba, but is hosted at sentry.io, and is thus not the maximum privacy option.

    Not sure which to pick? Most Android phones use arm64-v8a. If unsure, use the universal APK.

    Columba 2.2.6

    What's new in v2.2.x

    This stable release includes the following new features since v2.0.9:

    • voice call history screen
    • voice message attachments, interopable with sideband and meshchatx
    • displays LXMF resource transfer progress in message bubbles
    • export columba's shared reticulum instance config
    • in-app theme override (set dark mode even if your system is light or doesn't expose system level theme)
    • RNode battery level displayed on interface card and persistent notification
    • nomadnet truecolor support and newlines in form fields
    • experimental pyxis flasher
    • renders incoming markdown messages as markdown (no support for sending markdown LXMF messages yet)

    Plus tons of bug fixes, especially around BLE RNode handling, reconnecting and recovering from disconnects. Also several performance and stability improvements.

    I've removed the kotlin backend from this release, as it is not stable.

    Columba

    Columba is a simple messaging and voice app for the Reticulum network on Android. Send LXMF messages and make LXST voice calls without relying on the internet, cell towers, or any central servers.

    Built with a native Android interface and Material Design 3, Columba brings mesh networking to your pocket in a familiar, easy-to-use package.

    What You Can Do

    • Message without infrastructure - Send messages even when the internet is down or unavailable
    • Connect multiple ways - Use Bluetooth LE to connect to those around you anywhere, Wifi for those at home, LoRa radio via RNode for those at a distance, or use TCP to connect to any Reticulum server around the world
    • Stay private - End-to-end encryption with no accounts, no tracking, and no central servers
    • Share location - Share your location securely with others, viewable from a dedicated map
    • Download maps for offline use - Download or import map files. Supports vector and raster, in MBTiles format
    • Browse NomadNetwork - Access nomadnet pages over Reticulum networks
    • Build your network - Help relay traffic for others and expand the mesh
    • Keep your identity - Generate your messaging identity right on your device
    • Manage multiple identities - Easily swap between multiple identities
    • Export and import identities - Keep an external backup of your keys, or migrate to a new device. Import from other Reticulum clients like Sideband
    • Share your identity via QR Code - Built in QR code scanner and generator for sharing your identity with others
    • Custom Color Themes - Don't like the default colors? Rice to your heart's content!

    Getting Started

    Download the latest release from Releases and install on your Android device. See SECURITY.md for APK verification instructions.

    Alternatively, you can download the apk via NomadNet at 8d1788fdb4e9f85303cfdf7481e721c7:/page/index.mu

    About Reticulum

    Reticulum is a networking stack that lets devices communicate directly with each other, forming resilient mesh networks. It is optimized for low bandwidth, high latency connections, and can communicate over nearly any medium. Columba uses LXMF (Lightweight Extensible Message Format) to send messages across the Reticulum network, and uses a native Android implementation of ble-reticulum to enable messaging over BLE with other Android and Linux devices.

    Want to learn more? Visit Reticulum's documentation.

    Why "Columba"

    Columba, latin for "dove," is a constellation in the southern sky depicting a dove. Doves are commonly a symbol of peace and hope, and have been used as messengers throughout history.
