蓝牙间歇性断开

我使用的是运行Linux debian 4.19.0-9-amd64 #1 SMP Debian 4.19.118-2+deb10u1 (2020-06-07) x86_64 GNU/Linux.我的蓝牙经常停止工作，我必须重新启动计算机才能修复它。

运行sudo hciconfig hci0 reset产生：Can't init device hci0: Connection timed out (110)

hciconfig -a输出：

答案1

我也遇到了蓝牙间歇性连接问题。我使用以下命令使其工作而无需重新启动：

hciconfig hci0 down
rmmod btusb
modprobe btusb
hciconfig hci0 up

我希望这可以帮助你 ！

答案2

我在连接到任何蓝牙设备时遇到了这个问题，大约 30 分钟前刷新了操作系统，此后没有断开连接。
