已尝试论坛中的所有内容,包括(但可能不限于):
- 在 BIOS 中打开和关闭蓝牙
- 检查 rfkill 中的块(注意没有 hci 设备显示 rfkill 的任何内容)
- 检查以确保蓝牙服务正在运行(输出下方)
- 安装/升级 bluez(已尝试过 5.50 和 5.51)
- 集成 Wifi / 蓝牙卡(英特尔 AX200)的附加固件 - 请注意,该卡要求我从英特尔网站将 ucode 文件添加到 /lib/firmware,只是为了让 Wifi 工作 - 蓝牙仍然无法打开。
- 升级内核(我已经运行了从 5.0 - 5.3.6 开始的所有版本。请注意,Intel AX200 表示它需要 5.1+)。
