苹果键盘a1016，配对失败

  • 772

我无法将无线 a1016 Apple 键盘与运行 Ubuntu 17.10 的戴尔 XPS 笔记本电脑配对。

我已经看过这些线程，它们的说明对我的情况没有帮助： Pair Apple Wireless Keyboard 3rd gen with Ubuntu 16.04? 并且 Apple 无线键盘在 15.10 中无法连接

我尝试通过系统设置 GUI，其中设备被列为“未设置”。我点击它，然后有时，在我按下蓝牙键盘上的一个按钮后，我会看到 PIN 请求窗口。我输入请求的 PIN，然后 Enter，但要么什么都没有发生（通常），要么刷新窗口并请求一个新的 PIN。

我还尝试通过终端（bluetoothctl 命令提示符），尝试信任设备，然后连接/配对，但没有任何运气。错误是 ConnectionFailed 或 AuthenticationTimeout。尝试使用 blueman 包，它似乎是 bluetoothctl 的 GUI。没运气。

相同的键盘与 iMac 完美配对，因此这不是硬件问题。想法？

UPD：来自 bluetoothd 和 hcidump 的各种尝试的日志，也许这会有所帮助

尝试从 bluetoothctl 连接：

  1. 我没有戴尔 XPS，也没有使用 Ubuntu，但我使用 bluetoothctl 将 Apple 无线键盘型号 A1016 与 Debian 9.9（拉伸）上的蓝牙加密狗配对。

    1. 关闭键盘。键盘可以使用充电电池，但最好使用新电池。

    2. 运行蓝牙ctl。输入以下命令。

    打开

    代理 KeyboardOnly

    1. 在键盘上，盲目输入 12345678 并按回车键。

    2. 将出现 bluetoothctl 中的消息提示。

    [agent] Enter PIN code:

    键入 12345678 并在 bluetoothctl 中按回车键进入此提示。

    1. bluetoothctl 应该显示消息说键盘已配对。（xxxxxx 可能对您来说是独一无二的）

  2. Best Answer

    我试图将这个特殊的键盘连接到几个带有 Ubuntu 的戴尔 XPS笔记本电脑，从 16.04 到 18.04，但这些尝试都没有使用各种软件：bluetoothctl CLI 工具、KDE ​​蓝牙工具、Gnome 设置蓝牙 GUI、一些第 3 方的 GUI（我不甚至不记得 ATM 的名字）。

    没有机会尝试不同的硬件，放弃并购买了另一个键盘。

    显然，这种键盘无法连接到带有 Ubuntu 操作系统的戴尔 XPS。
