Attune 车机Attune for a car head unit

下载

Download

这是可侧载的官网发布包，使用 Attune 稳定签名，但不是应用商店分发包。安装前请核对发布清单中的 SHA-256；大屏需要允许未知来源安装。

This is the official sideload package from the Attune website and uses the stable Attune signer. It is not an app-store distribution. Check the SHA-256 in the release manifest before installing.

版本、源码 commit、签名指纹与 SHA-256 以 releases/android.json 为准。

Version, source commit, signer fingerprint, and SHA-256 are published in releases/android.json.

安装包里带 Quectel 驱动。没插上 2c7c:0125 时驱动等待。正式官网包使用固定 Attune 签名；签名一致且版本号更高时可直接覆盖升级。

The package includes the Quectel driver. Without a 2c7c:0125 board it waits and does not treat the phone as the dialing line. Official website packages use the stable Attune signer and can upgrade an existing install when the signer matches and the version code increases.

这个包能做什么

What this build does

打开后是手机式拨号盘：大号号码、圆键、绿色拨打、红色挂断。底栏可在电话、短信、历史、线路、板卡之间切换。没插板时用账户 MCP。登录后同一账户可在官网远程打开这台设备。点「语音办事」后和助手双向说话，你开口时助手会停下。文本模型负责调用拨号、短信和线路工具。手机测试时拨号走软路由板卡。

The screen is a phone keypad: a large number, round keys, a green call button, and a red hangup. The bar switches among phone, SMS, history, lines, and the board. With no board plugged in, actions use the account MCP. After sign-in the same account can open this device from the website. Voice stays open both ways, and speaking interrupts the assistant. A text model calls the dial, SMS, and line tools. On a phone, dialing uses the soft-router board.

插上 Quectel 2c7c:0125 时，应用只占用能应答 AT 的接口。上网接口留给系统，板卡自己的 LTE 仍可作为出口。

With a Quectel 2c7c:0125 board attached, the app claims only the AT interface. The network interface stays with Android, so the board's LTE can remain the uplink.

这一版没有在车机上运行 VoWiFi / IMS 媒体引擎。模型说已经拨出，只表示账户线路开始拨号，不表示对方已经接通。Qwen3 Omni Flash 不能调用工具，账户里要保存 Qwen 3.5 或 Qwen 3.8。

This build does not run the VoWiFi or IMS media engine on the head unit. A started call means the account line began dialing, not that the other party answered. Qwen3 Omni Flash cannot call tools; the account needs Qwen 3.5 or Qwen 3.8.

账户、Remote Link 与设备身份

Account, Remote Link, and device identity

登录后，这台车机以自己的设备身份注册到当前账户，可自定义设备名并在官网 Workspace / 设备页查看在线状态。账户数据按用户隔离；没有本地板卡媒体时，通信动作可以走该账户已经连接的线路与 MCP 工具。

After sign-in, the head unit registers as its own device under the current account. You can give it a device name and see its online state from the website Workspace/device page. Account data stays user-scoped; when local board media is unavailable, communications can use lines and MCP tools already connected to that account.

远程能力受账户权限与设备实际公开能力限制。语音助手只能调用 tools/list 返回的工具；不要把“工具存在”理解为任意 shell、ADB 或通用设备控制。

Remote capability is limited by account authorization and what the device actually advertises. Voice can call only tools returned by tools/list; this is not arbitrary shell, ADB, or generic device control.
