答案1

解决这个问题可能需要来回互动，您需要采取以下行动：

  1. 及时发布各种诊断命令的输出。
  2. 检查提供的链接。

这在评论中已经发生了。

请发布输出

$ apt list --installed bluetooth* blueman* bluez*
$ lsmod | grep -i blue
$ dmesg -T | grep -i blue
$ bluetooth
$ find /lib/modules/$(uname -r) -type f -name '*.ko*' | grep 8723
$ grep 8723 /lib/modules/$(uname -r)/modules.alias
$ grep 8723 /lib/modules/$(uname -r)/modules.dep

暂定的解决方案：

  1. 在 BIOS 中禁用蓝牙，重新启动并在 BIOS 中再次启用它。例如，这和这。

  2. 按照这，（WiFi+蓝牙）适配器Realtek RTL8723DE 802.11b/g/n (1x1) 和蓝牙® 4.2 组合。可能是因为驱动程序不可用。要检查这一点，您可以查看以下输出：上面的命令，或者你也可以尝试输入 modprobe rtl8723然后按 <tab> 查看制表符补全选项。如果没有，则必须安装它。例如，参见这，这， 或者这。

  3. sudo systemctl bluetooth.service start

答案2

检查蓝牙状态

sudo systemctl status bluetooth

如果它不活跃那么

sudo systemctl enable bluetooth

sudo systemctl bluetooth.service start

扫描

bluetoothctl scan on

为了使其他设备可以发现您的蓝牙适配器，

bluetoothctl discoverable on

连接到您的设备

bluetoothctl pair FC:69:47:7C:9D:A3

bluetoothctl connect FC:69:47:7C:9D:A3

使用 bluetoothctl 列出已配对的设备

bluetoothctl paired-devices

信任配对设备

bluetoothctl trust FC:69:47:7C:9D:A3

断开蓝牙设备

bluetoothctl remove FC:69:47:7C:9D:A3

bluetoothctl disconnect FC:69:47:7C:9D:A3

使用交互模式

bluetoothctl
