戴尔 XPS 13 9310 蓝牙找不到任何东西

  • 772

刚刚在我全新的 XPS 13 上安装了 Ubuntu 20.04。蓝牙处于活动状态，它找不到任何东西。有一次它找到了“音频设备”和“未知”，但我什至无法点击。

我尝试bluetoothctl了power on,scan on等等，但它什么也找不到。

我什至不知道我的戴尔使用哪种蓝牙设备，因为它不会出现在 lspci 或 lsusb 上：

我5.10.0-051000rc6-lowlatency之所以选择是因为 ubuntu 20.04 附带的那个在睡眠和其他方面存在问题。

我如何知道我正在使用哪个蓝牙设备？

PS：我也没有wifi，好像驱动Network controller: Qualcomm Device 1101 (rev 01)还没准备好。

我尝试了ubuntu 20.10，但安装时出错，尝试了很多次。但我猜这个问题与内核有关。

    如您所见，蓝牙设备没有固件。

    您可以通过这种方式安装它。在终端中运行

    sudo apt install git
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo cp linux-firmware/qca/htbtfw20.tlv /lib/firmware/qca
sudo cp linux-firmware/qca/htnv20.bin /lib/firmware/qca

    然后重新启动。

    注意： Ubuntu 20.10 最初有这个固件。

    更新：现在你有另一个问题

    [   12.685060] Bluetooth: hci0: command 0xfc00 tx timeout
[   21.069061] Bluetooth: hci0: Reading QCA version information failed (-110)

    这与内核驱动程序有关。我建议通过运行安装 5.8 内核

    sudo apt install linux-generic-hwe-20.04-edge

    并重新启动。

    您当前的内核将保持不变，您将始终能够恢复它。
