蓝牙在debian 10中不起作用

Question

在我的笔记本电脑中，我使用了debian 9，而蓝牙工作得很好。在蓝牙不起作用之后，我已经将debian更新到了10版本。我对linux不太在行。你能帮帮我吗?

lspci -nnk | grep -iA3 net; lsusb; dmesg | egrep -i 'blue|firm'

日志消息表明系统正在寻找英特尔BlueTooth (ibt)固件文件，首先在/lib/firmware/intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq，然后在/lib/firmware/intel/ibt-hw-37.7.bseq，但没有找到固件文件的任何一个版本。

转到intellinux固件git树的子目录，在那里找到正确的固件文件，然后单击一行末尾的“平原”，然后用文件名下载它。然后将文件放到您的/lib/firmware/intel目录中，然后重新启动(或者卸载和重新加载适当的内核模块)。该方法适用于所有Linux发行版，也适用于尚未由发行版打包的固件。

或者，确保启用了Debian包存储库(如有必要，请参阅服务器故障上的问题以获得说明)的非空闲部分，并确保安装了包firmware-iwlwifi。根据包装目录，它还包括所需的固件文件。此方法特定于Debian。
