 设置开机自动启用蓝牙设备，编辑`/etc/bluetooth/main.conf`文件，将`AutoEnable`设置为 true 即可。
 
+博通（Broadcom）网卡在 Linux 下的支持度很差，无论是无线还是蓝牙模块。对于无线功能来说，一般直接安装 broadcom-wl 包即可。
+
+```bash
+sudo pacman -S broadcom-wl
+```
+
+对于蓝牙模块，需要查阅[broadcom-bt-firmware](https://github.com/winterheart/broadcom-bt-firmware)仓库，在 brcm 文件夹中找到适合于自己网卡型号的 hcd 文件，将其下载并置于 `/lib/firmware/brcm` 文件夹中后重启即可。如果你无法确认自己的网卡型号对应哪一个 hcd 文件，那就全部下载并置于文件夹中。

 To set the bluetooth device to automatically start at boot, edit the `/etc/bluetooth/main.conf` file and set `AutoEnable` to true.

+Broadcom network cards are poorly supported under Linux, both wireless and bluetooth modules. For the wireless function, generally install the broadcom-wl package directly.
+
+```bash
+sudo pacman -S broadcom-wl
+```
+
+For the Bluetooth module, you need to consult the [broadcom-bt-firmware](https://github.com/winterheart/broadcom-bt-firmware) warehouse, find the hcd file suitable for your network card model in the brcm folder, and download it And put it in the `/lib/firmware/brcm` folder and restart it. If you can't confirm which hcd file corresponds to your network card model, then download all of them and put them in a folder.
