这边测试正常，是不是短链后资源被占 提供的sh 执行后吧日志反馈下

步骤如下：
1. 运行脚本
2. 打开电脑端蓝牙开关
3. 打开蓝牙鼠标，进入连接模式
4. 电脑端点击连接，弹出失败消息，再点一次连接，还是弹出失败消息。

从反应的情况来看   连接成功后，直接认证拒绝，并且断开连接。
采用bluetoothcl也发生类似的问题，所以和系统的关系不大。

可以排查一下以下几点：
1. 使用d-feet工具或者qdbus查看蓝牙适配器的Pairable的属性
2. 查看设备block属性
3. 可能是协议不支持，当配对成功时，bluez会尝试连接all profiles，如果profile协议不支持，也会返回org.bluez.Error.AuthenticationCanceled

能否提供一下具体的bluez日志呢
sudo vim /etc/systemd/system/bluetooth.target.wants/bluetooth.service
ExecStart=/usr/lib/bluetooth/bluetoothd -d

reload就可以输出bluez的详细日志了

同样的问题，windows10下就可以用。linux下都不行。华为使用了很多不公开参数的硬件。坑爹啊！

经测试，HUAWEI mouse 可以用在更换了蓝牙适配器的Thinkpad E431的Linux上，说明这不是蓝牙鼠标本身的问题。而是操作系统的问题。
Matebook13上安装了Ubuntu, Linuxmint和uos，均有此问题。

实际上linux大部分用的bluez进行连接
你可以看一下   可以连接的linux上面的bluez的版本
bluetoothctl -v

然后跟连接不上的版本进行比对

请问一下bluez的日志是哪个？
附件中的可以吗？


[CHG] Device E5:4F:38:27:34D Connected: yes
[CHG] Device E5:4F:38:27:34D Connected: no

版本是相同的。
bluetoothctl: 5.50

sudo vim /etc/systemd/system/bluetooth.target.wants/bluetooth.service
然后将其中一行
ExecStart=/usr/lib/bluetooth/bluetoothd -d

然后
systemctl daemon-reload   

通过
sudo journalctl -f /usr/lib/bluetooth/bluetoothd  获取日志

似乎报错并没有产生日志呢。
