蓝牙无法正常工作 - Ubuntu 15.04 Qualcomm Atheros AR9485

我有一台装有 Ubuntu 15.04 的联想 G510,但我就是看不到蓝牙(以前它能用)

elichai2@Lenovo-G510:~$ dmesg | grep -i blue

elichai2@Lenovo-G510:~$ lsmod | grep blue

如果有人知道如何修复它,我很乐意听听(如果您有补丁,我甚至愿意重新编译整个系统)谢谢!

附言:我dmesg | grep -i blue再次运行,现在我发现了以下几行:

[    4.780100] usb 1-7: Product: Bluetooth USB Host Controller
[   16.342944] Bluetooth: Core ver 2.20
[   16.342958] Bluetooth: HCI device and connection manager initialized

[   16.342964] Bluetooth: L2CAP socket layer initialized
[   16.342968] Bluetooth: SCO socket layer initialized

运行lsmod | grep blue后得到了新的结果:

bluetooth             491520  2 ath3k,btusb

并且蓝牙刚刚恢复到 rfkill :)

elichai2@Lenovo-G510:~$ rfkill list

使用最新的编辑,您需要做的就是打开一个终端窗口并输入

rfkill unblock all

如果它不能修复蓝牙,很可能是因为你没有安装固件

sudo apt-get install linux-firmware
sudo modprobe -r btusb
sudo modprobe -r ath3k
sudo modprobe ath3k
sudo modprobe btusb
