问题描述

我希望我的 Android 和 iOS(具体来说是 Swift)应用程序连接到网络中的 Raspberry Pi.当然，我可以为 Pi 设置固定 IP 并将 IP 硬编码到应用程序，但我想知道如何更动态地执行此操作.

I want my Android and iOS (Swift to be specific) apps to connect to the Raspberry Pi in the network. Of course I can set a fix IP for the Pi and hardcode the IP to the apps, but I would like to know how to do it more dynamically.

我需要在双方做什么才能让应用发现 Pi?

What do I need to do on both sides to allow the apps to discover the Pi?

推荐答案

如果您通过 Wifi(接入点)连接，那么您可以使用 SSDP 协议发现设备.它在 进行多播1900端口，加入特定组的人将收到并可以回复信息.它可以在App端和Pi上实现.
