我在 arch linux 上，想通过 bluetoothctl 通过蓝牙连接我的 Bose QC 35 II 耳机。行为非常奇怪。我可以毫无问题地发出配对命令。然后我发出连接命令。我从已连接的耳机获得音频反馈。约 6 秒后，耳机再次断开连接。
系统配置
bluetoothctl: 5.71
pulseaudio 16.1
extra/bluez 5.71-2
Bluetooth adapter: ISY IBT-1000 5.0
根据建议，我已将ControllerMode = bredr/etc/bluetooth/main.conf（来自https://flx.ai/2019/bose-qc35ii-linux#deactivate-bluetooth-le）
运行时错误
这是我运行 bluetoothctl 命令时的输出：

也许更重要的是日志 -xfe 输出：

最后一个错误暗示 bluez 电池组件出了问题。我考虑过修补代码，但我没有在系统上执行此操作的技能，而且我不知道这是否会破坏其他东西
有人知道我下一步可以尝试什么吗？
