它一直工作到最近。虽然,我确实经常按下鼠标底部的按钮。

这是输出:tail -f/var/log/syslog | grep 蓝牙

虽然我尝试了很多东西。

OC:FC:CA:00:08:5D 是我尝试连接时弹出的蓝牙设置窗口中报告的地址。状态会短暂更改为已连接,然后在大约一秒钟后返回到已断开连接。

最佳答案

尝试这个:

$ dmesg | grep -i bluetooth | grep -i firmware

我收到固件错误:
[   16.230350] bluetooth hci0: Direct firmware load for brcm/BCM-0a5c-6412.hcd failed with error -2

我在 git 上找到了驱动程序:

Broadcom firmware

并在驱动程序目录中复制并重命名:
$ sudo cp /share/BCM4350C5-0a5c-6412.hcd /lib/firmware/brcm/BCM-0a5c-6412.hcd
