苹果键盘a1016，配对失败

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

我已经看到这些帖子，其中的说明对我的情况没有帮助： 将 Apple Wireless Keyboard 第三代与 Ubuntu 16.04 配对？和 Apple 无线键盘在 15.10 中无法连接

我尝试通过系统设置 GUI 进行设置，其中设备显示为“未设置”。我单击它，然后有时，在我按下蓝牙键盘上的按钮后，我会看到 PIN 请求窗口。我输入请求的 PIN 然后按 Enter，但之后要么什么都没发生（大多数情况下），要么窗口刷新并请求新的 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，但没有任何成功。错误是 ConnectionFailed 或 AuthenticationTimeout。尝试使用 blueman 包，它似乎是 bluetoothctl 的 GUI。没有成功。

相同的键盘与 iMac 完美配对，所以这不是硬件问题。您觉得呢？

更新型多巴胺：来自 bluetoothd 和 hcidump 的各种尝试的日志，也许可以提供帮助

尝试从 bluetoothctl 连接：

我没有 Dell XPS 也没有使用 Ubuntu，但是我使用 bluetoothctl 将 Apple Wireless Keyboard 型号 A1016 与 Debian 9.9（stretch）上的蓝牙适配器配对。

  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bluetoothctl。输入以下命令。

打开

代理 KeyboardOnly

默认代理

可配对

  1. 打开键盘。键盘灯会闪烁 2 次，暂停，闪烁 2 次，暂停，然后重复。

  2. 在 bluetoothctl 中输入以下命令。

扫描

  1. 等待“Apple Wireless Keyboard”出现。记下 MAC 地址。假设它是 00:0A:95:33:33:33。

  2. 在 bluetoothctl 中输入以下命令。

连接 00：0A：95：33：33：33

  1. 在键盘上盲输入 12345678，然后按下返回钥匙。

  2. bluetoothctl 中会出现消息提示。

在 bluetoothctl 中的提示符中输入 12345678 并按回车键。

  1. bluetoothctl 应该会显示消息表明键盘已配对。（xxxxxx 可能对你来说是唯一的）

答案2

我尝试将这个特定的键盘连接到几个戴尔XPSUbuntu 16.04 升级至 18.04 的笔记本电脑以及这些尝试均未奏效使用各种软件：bluetoothctl CLI 工具、KDE ​​蓝牙工具、Gnome 设置蓝牙 GUI、一些第三方 GUI（我甚至不记得 ATM 这个名字）。

没有机会尝试不同的硬件，放弃了并购买了另一个键盘。

显然，这种键盘无法连接到装有 Ubuntu 操作系统的戴尔 XPS。
