Bluetooth 헤드셋을 자동으로 연결할 수 없습니다(Ubuntu).

2024-6-5 • tag-icon

내 Bluedio T4 헤드폰이 Ubuntu Linux 20.04 LTS에서 자동으로 연결되지 않습니다.

장치는 PulseAudio /etc/pulse/default.pa에서 신뢰할 수 있고 활성화되어 있습니다. Wireshark를 사용하면 컨트롤러에 매우 빠르게 연결되는 것을 볼 수 있습니다. 그러나 몇 밀리초 후에 연결 해제 요청을 보내고 이에 따라 장치 연결이 끊어집니다.

기기가 문제 없이 내 Android 기기에 연결되기 때문에 이런 일이 발생하는 이유를 모르겠습니다.

나도 같은 문제가 있습니다 (그러나 Debian Buster와 bluedio t6을 사용하고 있습니다).

섹션 FastConnectable에서 옵션 을 변경해 보았습니다 .true/etc/bluetooth/main.conf[General]

# Permanently enables the Fast Connectable setting for adapters that
# support it. When enabled other devices can connect faster to us,
# however the tradeoff is increased power consumptions. This feature
# will fully work only on kernel version 4.1 and newer. Defaults to
# 'false'.
#FastConnectable = false
FastConnectable = true

그런 다음 재부팅합니다.블루투스, 이제 헤드셋을 켜자마자 바로 연결됩니다.
