从 18.04 升级到 20.04 后，Thinkpad T530 上的蓝牙停止工作

从 18.04 升级到 20.04 后，Thinkpad T530 上的蓝牙停止工作

我不断收到此消息“您的默认蓝牙适配器对远程设备不可见。”我尝试将设置更改为可见，但它总是恢复为不可见。

dmesg |grep -i firm 显示“brcm/BCM20702A1-0a5c-21e6.hcd 的直接固件加载失败，错误为 -2”

感谢您提供的修复帮助。

wget -c https://github.com/winterheart/broadcom-bt-firmware/blob/master/brcm/BCM20702A1-0a5c-21e6.hcd

将固件文件 cp 或 mv 到/lib/firmware/brcm/
