Android Question Connect two phones via IP without remote server

[b4a programmer]

Hi,
I want to exchange information between two phones remotely without a server and using ip. Is it possible and how? Please attach a source.
Thanks?

1. Start a local hotspot: https://www.b4x.com/android/forum/threads/start-local-hotspot.98664/#content
2. Connect the second device to this network.
3. Connect both devices with: [B4X] Network + AsyncStreams + B4XSerializator

Note that you will need to use ServerSocket.GetMyIp (instead of GetMyWifiIp) on the hotspot device, to get the current ip address.

Is it possible to connect two devices, one in the United States and the other in France, this way?

Of course not.

You cannot connect two devices over the internet, without a server or a specially configured local network (see this: https://www.b4x.com/android/forum/t...p-to-your-b4j-server-over-the-internet.37201/)

But I have heard that Telegram does this with WebRTC in voice and video calls.

Using a WebRTC Server most probably!
