Debian 蓝牙驱动问题排查与解决
一 快速自检与基础修复
lsmod | grep bluetoothsudo apt-get install bluetooth bluezsudo systemctl start bluetooth && sudo systemctl enable bluetoothhciconfig -a 或 bluetoothctl listdmesg | grep -i bluetoothbluetoothctlpower on → scan on → pair <MAC> → trust <MAC> → connect <MAC>sudo apt-get install blueman二 常见厂商方案与固件缺失处理
sudo apt-get install firmware-brcm80211sudo apt-get install firmware-atherossudo m-a a-i omnibook-sourceecho "omnibook" | sudo tee -a /etc/modulesecho "options omnibook ectype=14" | sudo tee /etc/modprobe.d/omnibook.confsudo modprobe omnibook ectype=14
以上为常见硬件在 Debian 上的可行路径,优先使用官方仓库固件,其次再考虑社区固件或厂商模块方案。三 服务与权限配置要点
sudo apt-get install bluezsudo usermod -aG bluetooth $USERbluetoothctl power on → scan on → 配对连接四 日志定位与社区求助
dmesg | grep -i bluetooth、journalctl -u bluetooth -bhciconfig -a、rfkill listuname -a)lsusb/lspci 输出)、固件是否安装
