戴尔 XPS 13 (9370) 蓝牙问题

Question

我的新戴尔 XPS 13 (9370) 上的蓝牙模块存在以下问题，预装了 Ubuntu。

由于某种原因，蓝牙模块被禁用。蓝牙设备（键盘和鼠标）在工作中途停止工作，蓝牙指示灯消失，模块也消失在rfkill列表中。

为了让它恢复工作，我需要重新启动机器，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系统日志：

我已经尝试过不同的事情：

1. 禁用 TLP 和禁用蓝牙的 TLP /etc/default/tlp
2. 将 BIOS 更新至 1.2.1 版
3. 将此行设置为 ath10k 的 modprobe： echo "options ath10k_core skip_otp=y" > /etc/modprobe.d/ath10k.conf
4. 更新linux-firmware包，就像这里提到的：https : //www.killernetworking.com/driver-downloads/kb/faq/1-killer-1535-1525-1435-in-ubuntu-debian

直到现在，这些都没有帮助。

据我所知，它是以下硬件：QCA 6174 Killer Qualcomm / QCA 1535 Killer Qualcomm

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的 Windows 驱动程序中包含的文件更新蓝牙固件来改进它。我的 MD5：

067fb95e8501bad2683df07d23539e7d  nvm_usb_00000302.bin

86c377ab7b2c24cc12cea5e79f71d610  rampatch_usb_00000302.bin_orig

顺便说一下，一个更简单的解决方法是拔掉电源并执行挂起/恢复循环。
至少我的是 1435 Killer。

更新 Sven Killig 对 Ubuntu 18.04 上 Dell XPS 9370 的回答：
