有这个文件/lib/firmware/ar3k
$ du -h /lib/固件/ar3k
36K /lib/firmware/ar3k
Ubuntu 22.04目录下没有ar3k目录，我尝试创建这个目录，然后执行sudo cp linux-firmware/ar3k/AthrBT_0x11020000.dfu /lib/firmware/ar3k，重启后dmesg报错说缺少新文件：Patch file not found ar3k/ramps_0x11020000_40.dfu，然后我去Google找了一份，重启后错误变成了这样

答案1
您的蓝牙硬件固件尚未安装。您可以通过以下方式安装。在终端中运行：
sudo apt install git
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo cp linux-firmware/ar3k/AthrBT_0x11020000.dfu /lib/firmware/ar3k
sudo modprobe -r btusb
sudo modprobe btusb
你的蓝牙应该可以正常工作。
答案2
我也遇到过这个问题。然后我测试了 22.10，也遇到了同样的问题。结果发现，从 22.04 开始，Blueman 在“查看”下拉菜单中添加了一项名为“隐藏未命名设备”的新“功能”。真正的问题是该功能默认为启用状态。猜猜怎么着？每个 BT 设备都是未知的，直到它不是！所以它们都被隐藏了。不聪明。
只需取消选中此框，将您的 BT 设备置于配对模式，单击“搜索”，然后再次享受蓝牙！
