当我尝试将蓝牙扬声器连接到我的新华硕 TP500LB 时，Blueman-Applet 提供了使用“随机密码”或不连接的选项，但没有提供输入扬声器提供的密码的选项。（此类设备的默认密码为：0000）什么鬼！！！？？
我该如何连接到任何有密钥的设备？这应该是显而易见的。看起来有人在试图制造事情“简单的”通过减少用户可用的功能。每次都是个坏主意。我是一个非常精通技术的人。我从 1983 年开始使用电脑。如果我遇到困难，我保证其他人也会遇到同样的问题！
当我尝试连接时，Bluetoothctl 给出以下输出：

我安装了 Bluedevil 并尝试了 bluedevil-wizard。输出如下：

我也尝试过连接 hcitool。但还是没成功。
尝试通过“蓝牙设备”小程序进行连接会产生以下结果：
Connection Failed: DBusFailedError: No such file or directory
不确定哪个文件不存在...有人有什么想法吗？
好吧，这个问题让我很困惑！过去三个小时我一直在论坛和谷歌上搜索，但一无所获。我怀疑答案就在 Bluedevil-Wizard 的输出中，它说“没有这样的文件或目录”。这只是一个找出哪个文件的问题……
