ubuntu 14.04 蓝牙 BCM43142 未发现（tx 超时）

2024-6-4 • tag-icon

我浏览了许多与该问题相关的帖子，但没有找到一个完整的答案。

问题：无法发现\检测其他蓝牙节点。

正如您在上面的代码片段中看到的，最后两行——似乎驱动程序有问题。

请注意，我们正在谈论组合网卡。即，它是物理网络接口卡上的 wifi 和蓝牙设备。

能否有人解释一下这个问题：

怎么了？
有没有什么软件解决方案？（我知道我可以购买不同的硬件）

更新： 我按照 pilot6 链接操作，并针对两种架构执行了那里描述的步骤。即 32 位和 64 位。我已关闭计算机，但问题尚未解决。附上更多信息，如果需要任何其他信息，请告诉我。

我不确定，但看起来好像固件没有加载：

查看底部第 4 行—— Driver=btusb。因此，我不确定复制固件是否有帮助。

更新2： 这正是我所做的：

答案1

您需要先安装固件。可以使用这个答案。

但看起来内核 3.13.0-59 有很多 bug，其中包括无法加载固件。

我建议将内核升级到 3.19。可以在终端中运行

sudo apt-get install linux-generic-lts-vivid

然后重新启动。
