Question by unity_18A25F63BBB0296F277D · Dec 09, 2021 at 05:35 PM · networking

Web RTC connection dropping

Hi,

I'm trying establish a WebRTC connection, with a data channel, between the unity editor and my Oculus quest 2. I have the offer and answer exchanges figured out.

My issue:

If both devices are on the same network the RTCIceConnectionState makes it all the way to Connected, the data channel opens, and a couple second later the connection drops.

If the devices are on different networks the connection gets stuck in the Checking state.

Any debugging tips or tricks?

I've resolved this issue.

For posterities sake.

The remote host does not need to wait for dataChannel.OnOpen. When OnDataChannel fires you are good to go. Add a OnMessage handler and you're off.

I have a similar issue however I never have problems with local networks but as soon as something is on a different network I get stuck in Checking. TURN servers are available and added but I can't tell what is happening under the hood? Adopted my framework using the DataChannel example.
