根据https://wireless.wiki.kernel.org/en/users/drivers/ath3k?s[]=ar3012，必须使用这些文件的组合，但我不确定哪些文件适用于我的情况：

For AR3012, you can find the “AthrBT_0x01020200.dfu” and “ramps_0x01020200_26.dfu” or “ramps_0x01020200_40.dfu” on the linux-firmware git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/ar3k/

modinfo ath3k并modinfo ath3k | grep 3004证实了我的期望：

行为

登录时，蓝牙图标可能会或可能不会加载到托盘中。
蓝牙切换可能有效，也可能无效。
当蓝牙开关工作时，搜索没有找到任何内容。试过我的手机和蓝牙音频。

蓝牙（Atheros AR3012）在 Ubuntu 16.04 上无法使用- 没有答案

Ubuntu 16.04 中带有 [0cf3:3004] Atheros 适配器的蓝牙无法工作-- Pilot6 的解决方案不起作用（这个，我昨天在重新安装干净的操作系统之前尝试过）。

答案1

我遇到了同样的问题，我发现这个表格对我有用（https://forums.bunsenlabs.org/viewtopic.php?id=4375）

简而言之：

尝试

sudo bluethoothcli

如果它说：“没有默认控制器”那么这个解决方案可能适合您：

在此处下载列出的驱动程序（https://github.com/winterheart/broadcom-bt-firmware/tree/master/brcm）
创建一个名为BCM.hcd的目录

sudo mkdir -p /lib/firmware/brcm/BCM.hcd

将驱动程序复制到该文件夹

sudo cp BCM43142A0* /lib/firmware/brcm/BCM.hcd

完全关闭计算机，然后打开并尝试

sudo bluethoothcli

如果你能打字
