戴尔XPS 13（9370）蓝牙问题

我的新款Dell XPS 13（9370）上预装了Ubuntu的蓝牙模块出现以下问题。

蓝牙模块由于某种原因被禁用。 蓝牙设备（键盘和鼠标）在工作过程中停止工作，蓝牙指示灯消失，模块也在rfkill列表中消失。

为了让它恢复工作，我需要重启机器，启动BIOS，禁用蓝牙模块并重新启用它。 之后，蓝牙模块再次可用。 这很烦人。

发生这种情况时我的syslog：

我已经尝试了不同的东西：

1. 在/etc/default/tlp禁用TLP并禁用蓝牙TLP
2. 将BIOS更新到1.2.1版
3. 将此行设置为modprobe for ath10k： echo "options ath10k_core skip_otp=y" > /etc/modprobe.d/ath10k.conf
4. 更新linux-firmware软件包，如下所述： https ： //www.killernetworking.com/driver-downloads/kb/faq/1-killer-1535-1525-1435-in-ubuntu-debian

直到现在，这一切都没有帮助。

据我所见，它是以下硬件： QCA 6174杀手高通/ QCA 1535杀手高通

大多数情况下，我将这两个蓝牙设备配对并连接：

• 罗技K810键盘
• 罗技MX Anywhere2鼠标

Answer 1

我遇到了同样的问题，我认为通过使用最新Windows驱动程序中包含的文件更新蓝牙固件可以改善它。 我的MD5：

 sonic@sonic-XPS-13-9370:/lib/firmware/qca$ md5sum *usb*302* 067fb95e8501bad2683df07d23539e7d nvm_usb_00000302.bin b3e2784b16b5b0cf5defa7eb9115956d nvm_usb_00000302.bin_orig c9d6334b547a92817458de10243f398c rampatch_usb_00000302.bin 86c377ab7b2c24cc12cea5e79f71d610 rampatch_usb_00000302.bin_orig 

顺便说一句，一个更简单的解决方法是拔掉电源并执行暂停/恢复循环。
至少我的是1435杀手。

在Ubuntu 18.04上更新Sven Killig对戴尔XPS 9370的回答：

Answer 3

对我有用的解决方法：关闭并关闭笔记本电脑，等待一点确定，然后再打开它。

我正在运行ubuntu 17.10顺便说一句，但这没什么区别:)
