블루투스 연결이 간헐적으로 끊김

Run 을 사용하고 있습니다 Linux debian 4.19.0-9-amd64 #1 SMP Debian 4.19.118-2+deb10u1 (2020-06-07) x86_64 GNU/Linux. Bluetooth 작동이 계속 중지되고 문제를 해결하려면 컴퓨터를 다시 시작해야 합니다.

실행하면 sudo hciconfig hci0 reset다음이 생성됩니다.Can't init device hci0: Connection timed out (110)

hciconfig -a산출:

어떤 도움이라도 대단히 감사하겠습니다. 이것은 매우 성가신 문제입니다. 감사해요.

답변1

또한 간헐적으로 Bluetooth 연결 문제가 발생합니다. 다시 시작하지 않고 작동하도록 다음 명령을 사용했습니다.

hciconfig hci0 down
rmmod btusb
modprobe btusb
hciconfig hci0 up

이것이 당신에게 도움이 되기를 바랍니다!

답변2

Bluetooth 장치에 연결할 때 이 문제가 발생하고 약 30분 전에 OS를 새로 고쳤으며 그 이후로 연결이 끊어지지 않았습니다.
