Unity SDK DataChannel

[gtk2k]

Can I use data channels with the Unity SDK?

SendDataChannelMessage() in the Unity SDK, but I've tried sending a string using this method, but I don't know how to receive it.

You need to have data channel enabled in ant media server. Incoming messages are handled in onNotify in the sample.cs. It should be something like sora.onNotify(...)

thanks you. I was able to send and receive strings on the data channel.

However, there is an extra character at the end of the received string ("test"-> "testV")

  > String conversion error: Partial byte sequence encountered in the input.

Error occurs.

Also, I want you to support sending and receiving binary data.

I have never experienced or seen it. Could you send a screenshot of it please.

For binary data, It is almost implemented but still requires a few changes and we haven't planned it yet.

DataChannel Test Movie

Left: Sender

Right: Receiver

sendData: "testtesttest"

 

[gtk2k]

// Sender
sendInterval += Time.deltaTime;

if(sendInterval >= 1f)

{

    sendInterval = 0f;

    sendLength += 100;

    var sendData = new string('w', sendLength);

    Debug.Log($"SendData length:{sendLength}");

    sora.SendDataChannelMessage(sendData);

}

// Receiver

sora.OnNotify = (data) =>

{

    Debug.Log($"Receive via DataChannel: {data.Length}");

};

It is the result of testing with such code

Sometimes it receives a length other than XX00 or the received data drops.

I'm not sure how this is related to SDK. If your processor has a margin of error and can pass string 0.001 later than it should be, I'm not sure what is the issue here. I don't think a webrtc datachannel should bomb data channel messages constantly.

What happens when you try a real worl scenario where you wrote text and  send by button but don't mash it 10 times in a second.

Could you post your findings please?

Hope you are doing well, have you noticed my previous reply?

Were you able to do a proper test?

Hi Gtk2K,

Eagerly waiting your answer to see the results!

We created and tested a project to compare the behavior of WebRTC Assets.
https://github.com/gtk2k/UnityWebRTCAssetsTestForAMS

While Ant Media Server Unity SDK causes packet loss and message error when sending and receiving data on the data channel, WebRTC for Unity (Unity Official) was able to send and receive stably.

That is really cool! I will take look at it. Does it work on every platform? IOS, Android, Mac Windows?
