如果你在Ubuntu 18.04操作系统中有蓝牙鼠标连接失败问题，那就参考下面的解决方法处理。

解决方法

首先在系统终端下输入：

bluetoothctl

然后输入：

list

看清除 Controller 的 mac 地址，我的是 AC:2B:6E:91:65:4E，在终端输入：

select AC:2B:6E:91:65:4E

然后输入：

show

此时确保你的鼠标配对已打开，处于可被发现状态，输入：

scan on

在输出信息中找到你的鼠标后，即可输入：

scan off

并记下你鼠标的mac地址，如果你的鼠标连接时要求 pin code，则输入以下命令，若不用则跳过这一条（当然不确定的话需不需要 pin code 就执行一下，也没什么影响的）。

agent on

接下来使用上一条记下的鼠标mac地址，输入：

pair DC:2C:26:AE:35:41

出现 Pairing successful，即配对成功，中间要求 pin code, 就输入对应 pin code即可。这时配对成功，但是鼠标还不能操作，依次输入：

connect DC:2C:26:AE:35:41

trust DC:2C:26:AE:35:41

鼠标即可正常使用了。
