ArchLinux蓝牙问题:No default controller available

need_it · 2020-11-22 02:50:59

在Arch安装完成后，安装bluez、bluez-utils、bluedevil后可以正常在KDE界面使用蓝牙。在使用命令行bluetoothctl管理后打不到蓝牙适配器，初次运行bluetoothctl时可以找到适配器并配对、连接。重启计算计后蓝牙显示找不到蓝牙适配器。bluetoothctl与bluedevil都不能用。

这个是驱动有问题吗？我用另一台计算测试，也出现了相同的情况。

貌似这个是很常见的问题，人个认为应该是蓝牙固件的问题吧。

关机/或者是从windows切换到Linux会遇到这问题。

你可以先看下内核加载了蓝牙驱动没:

$ dmesg | grep Bluetooth 
.....
[    5.612537] Bluetooth: hci0: Found Intel DDC parameters: intel/ibt-11-5.ddc
[    5.616191] Bluetooth: hci0: Applying Intel DDC parameters completed
[    5.617166] Bluetooth: hci0: Reading supported features failed (-16)
[    5.617184] Bluetooth: hci0: Telemetry exception format not supported
[    5.618138] Bluetooth: hci0: Firmware revision 0.0 build 10 week 41 2018

[   14.691090] Bluetooth: RFCOMM socket layer initialized
[   14.691096] Bluetooth: RFCOMM ver 1.11

没有的话就看下自己的蓝牙驱动是啥，如我自己的是 btusb :

$ lsmod | grep bt
...
btusb                  69632  0
btrtl                  24576  1 btusb
btbcm                  20480  1 btusb
btintel                32768  1 btusb
bluetooth             741376  49 btrtl,btintel,btbcm,bnep,btusb,rfcomm

然后再自己手动加载蓝牙驱动下看:

sudo modprobe btusb

sudo modprobe btusb

btusb是通用蓝牙驱动，这个我的加载了

$ lsmod |grep bt
btusb                  69632  0
btrtl                  24576  1 btusb
btbcm                  20480  1 btusb
btintel                32768  1 btusb
bluetooth             741376  10 btrtl,btintel,btbcm,bnep,btusb

查看启动信息，这个我看不懂是不是加载成功。

看了下，驱动已经识别了蓝牙设备，
理论上应该在bluetoothctl list 是有设备的。

#这个标明驱动已经识别了
[    5.059752] Bluetooth: hci0: read Intel version: 370810011003110e32
[    5.059756] Bluetooth: hci0: Intel device is already patched. patch num: 32
# 这个是没有识别到某些功能而已，不碍事。
bluetoothd[1351]: src/main.c:parse_controller_config() Key file does not have key “LEAutoconnecttimeout” in group “Controller”

实在不行，就换hcitool看下，

注意：先看下用户在不在 rfkill 组里。

如果还是不行，那就只能升级BIOS看下了。

谢谢！应该是硬件有问题。暂时不用蓝牙了。
