有没有办法通过蓝牙驱动程序或替代驱动程序获得更好的体验?

我有一个蓝牙鼠标。它在 Mac 上运行良好。它在运行 Windows 的同一台机器上运行良好。基本上,正如您期望的那样,蓝牙鼠标可以正常工作。

在 Windows 中,在同一台机器上运行相同的物理蓝牙卡/鼠标对,但在 Ubuntu 下,鼠标只有与计算机在同一平面上且超出该平面时才能工作。如果我坐在桌子或书桌前,将手臂伸出笔记本电脑外,鼠标四处移动,它就会按预期工作。

如果您将鼠标移得比笔记本电脑更靠近您,或者将鼠标与笔记本电脑放在不同的平面上(不在同一张桌子/书桌上),它几乎不起作用,或者根本不起作用。

这似乎是 Ubuntu 及其蓝牙驱动程序的问题。有替代驱动程序吗?我可以在 Ubuntu 下以某种方式运行 Windows 10 驱动程序吗?

真的很想让我的鼠标在 Ubuntu 中正常工作。电池寿命也非常糟糕。但是,在 Windows 10 下,在我玩游戏的同一台机器上运行,电池寿命完全正常。

我在 16.10 上,在 16.04 上也遇到同样的问题。

当我运行 dmesg | grep -i blue 时输出

答案1

您需要安装固件。您可以在这个答案

问题是我没有最新的 Windows Broadcom 蓝牙驱动程序来获取新的固件文件。如果你有 Windows,那么你可以在 Windows 的某个地方找到固件,我不记得它把这些东西存储在哪里了。类似于windows64

需要注意的是,对于内核 4.8,您可能需要将文件命名为BCM-0a5c-6412.hcd。内核维护者总是更改文件名,这让人感到困惑。

更新:Broadcom 最终在其网站上提供了该驱动程序。
