Android：可以将蓝牙连接到自己吗？
[英]Android: Possible to connect bluetooth to self?
问题描述
At the beginning of this year, I tried to implement an android-app which could stream ALL system-audio to a remote system. 
今年年初，我尝试实现一个android-app，该应用程序可以将所有系统音频流式传输到远程系统。
This was not easy because (at that time) there was no way to get all system-audio. 这并不容易，因为（当时）无法获得所有系统音频。 So I developed a kernel-module which hijacked the audio. 因此，我开发了劫持音频的内核模块。
But it was a bit buggy and hard to release. 但这有点漏洞，而且很难发布。
So I stopped work on it. 所以我停止了工作。
But now, some months later I wonder if it is possible to: 但是现在，几个月后，我想知道是否有可能：
Connect via bluetooth to myself (= simulate bluetooth), because then I can forward system-audio to it via API and then fetch it on the other side.
Anyone an idea? 有人知道吗？

I doubt it. 我对此表示怀疑。 For a couple of reasons there is no loopback device for Bluetooth (see here also), which you would basically want to use. 出于几个原因，没有用于蓝牙的环回设备（另请参见此处 ），您基本上希望使用该设备。
You might try looking into using PulseAudio as a replacement for Android's AudioFlinger, as Pulse offers a loopback module for Linux at least. 您可能会尝试使用PulseAudio替代Android的AudioFlinger，因为Pulse至少为Linux提供了回送模块。
