未能添加蓝牙键盘(Microsoft键盘)

Question

我的BT键盘不对。你能帮帮我吗？

刚刚买了这套很不错的蓝牙桌面和这台华硕笔记本电脑，并在上面安装了Ubuntu15.04。

首先，我的老鼠没有配对。我通过安装Bluez5和蓝牙管理器修复了这个问题，正如埃里克·鲍尔这里所建议的：蓝牙鼠标对但不连接

现在键盘不对了。

在键盘上，我按了一个3秒的小按钮，把它放在配对模式中。蓝牙管理器看到键盘。我点击“安装”。BT经理说要在键盘上输入代码。我在键盘上输入这段代码，然后按回车键:砰，BT经理说“添加设备失败了”。

/var/log/syslog的最后一行如下所示。谢谢你的帮助!

Answer 1

这个问题是由于网关工具的问题。蓝牙设备调用gattool来获取蓝牙低能设备的属性。可能设备的固件不支持身份验证协议。

我通过启用蓝牙实验功能来避免这个问题。在您的/etc/init.d/蓝牙、NOPLUGIN_OPTION="-E“中添加"-E”选项。然后，重新启动蓝牙服务。

Answer 2

它通过更新布卢兹来为我工作：

apt-add-repository ppa:vidplace7/bluez5
apt-add-repository ppa:blueman/ppa
apt-get update
apt-get install bluez
apt-get install blueman
apt-get install bluez-compat

然后，我不得不在实验模式下启动bluez :用自己的脚本替换/usr/sbin/bluetooth：

#!/bin/sh
bluetooth -E

现在我可以连接到blueman-applet鼠标和键盘了。

有什么想法，如何在启动时自动连接或不使用blueman (只是命令行)？

对我来说，在尝试将蓝牙管理器中的键盘配对后，我注意到一个带有密码的小通知气泡。泡沫只存在几秒钟。我在键盘上输入密码，按回车键，然后键盘成对。

它花了几次尝试使它工作(把键盘重新进入配对模式)。
