为什么我的简单对等 WebRTC 可以在某些 android 手机上运行，​​而在其他手机上不能运行

如何解决为什么我的简单对等 WebRTC 可以在某些 android 手机上运行，​​而在其他手机上不能运行

我构建了一个聊天反应应用程序作为 PWA，它可以在台式机上运行，​​也可以在我的手机和我妻子的手机上运行，​​但不能在其他一些机器人上运行，也不能在 Iphone 上运行。我想知道是否有人知道为什么会这样。我也有连接的情况，但我看不到视频或音频，以及连接一次但我可以改天尝试但无法连接的情况。我认为这可能与将涓流设置为 false 有关，或者我现在需要更新我的简单对等 API，我有 9.7，但我看到他们有 9.10。 我的一个想法是它对我和我的妻子很有效，因为我们在同一个网络上。
