如何在东芝 satellite c55-896 笔记本电脑中找到内置蓝牙适配器

我已经使用Ubuntu一年多了，但是最近又遇到了一个老问题。

当我第一次安装 Ubuntu 时，蓝牙部分显示“未找到适配器”。我想买一个无线鼠标，但找不到解决办法。我可以使用我的端口进行外部蓝牙连接，或者买一台新笔记本电脑。

有人能帮我弄清楚为什么我的蓝牙无法被识别吗？

结果lspci -nnk | grep -iA2 net; lsusb 是：

启动板中的错误报告

结果uname -r是3.16.0-44-generic

rfkill 列表的结果是：

 0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

结果dmesg | grep -i blue是：

答案1

问题是该linux-firmware包不包含此模块所需的固件。显示为Patch file not found ar3k/AthrBT_0x31010100.dfu。

linux-firmware可以通过安装包含固件的软件包来解决这个问题。在终端中运行

wget https://launchpad.net/~hanipouspilot/+archive/ubuntu/rtlwifi/+files/linux-firmware_1.144%2Bar3012_all.deb
sudo dpkg -i linux-firmware*.deb

重启后您的蓝牙应该可以工作。

更新我已将此固件发送给linux-firmware维护人员，并且已将其添加。迟早它会进入 Ubuntu 存储库。
