此处列出的解决方案听起来可能有效,但实际上并没有。尝试后,固件在上面目录中列出:
-rw-r----- 1 root root 35127 Feb 5 01:26 BCM20702A1-13d3-3404.hcd
更新:我在这里的 Arch AUR 中找到了 bcm20702a1-firmware 。删除上面手动安装的文件后,我安装了 AUR 包(没有错误)。重启后问题依旧没有解决。
上面的目录现在包含所有这些文件:

请注意,BCM20702A1-0b05-180a.hcd 与我的错误消息中列出的硬件完全匹配,因此可以预期这已经解决了问题。它没。但是,日志看起来更好,所以也许这是朝着解决方案迈出的一步:

更新 2:在最后一步之后,一个更简单的步骤解决了这个问题:
systemctl start bluetooth.service
systemctl enable bluetooth.service
我会根据这个写一个答案。
我的问题的两次更新最终会导致解决方案。但是,作为更合适的答案,我相信这个确切错误的解决方案可以像以下步骤一样简洁:
我确实遇到了另一个问题:蓝牙文件传输失败 - a2dp-source 配置文件连接失败:协议不可用
设备未连接,日志中出现错误
如果您在尝试连接到设备时在 journalctl 输出中看到如下消息:
尝试安装 pulseaudio-bluetooth 并重新启动 pulseaudio。即使仅使用文件传输,此错误也会出现。
