我有一个 Broadcom 43142 组合 wifi+蓝牙网络适配器，我想让它与 Ubuntu 16.04 配合使用。我是 Linux 新手，因此很难理解互联网上的一些可能的解决方案。我发现的一个资源表示我需要从他们提供的列表中安装正确的固件。该 github 存储库的 ReadMe 页面包含一些终端输出，您可以在其中找到所需的固件，但它没有说明使用什么命令来实现该输出。示例输出如下：
Bluetooth: hci1: BCM: chip id 63
Bluetooth: hci1: BCM20702A
Bluetooth: hci1: BCM20702A1 (001.002.014) build 0000
bluetooth hci1: Direct firmware load for brcm/BCM20702A1-0b05-17cb.hcd failed with error -2
Bluetooth: hci1: BCM: Patch brcm/BCM20702A1-0b05-17cb.hcd not found
由此可以确定所需的固件是 brcm/BCM20702A1-0b05-17cb.hcd。
我如何在自己的系统上找到这些信息？
提前致谢。
更多信息：有些人可能会要求查看一些终端命令的输出。以下是我目前所得到的：

答案1
根据要求，这是问题的解决方案（从我在原始帖子中的编辑中复制）
显示我的蓝牙驱动程序的驱动程序状态所需的终端命令如下：
dmesg | grep -i bluetooth
谢谢大家的帮助。
答案2
这将产生比MProx 的答案
sudo dmesg | grep 'Firmware revision'
