Chrome doesn't support "reliable" (TCP) datachannels yet, but that's not the only reason this app doesn't work in Chrome. It would be great to at least fix the other reasons.

Chrome's security model doesn't normally allow any access to local devices/files from a "file://" URL. Adding "--allow-file-access-from-files" to the Chrome command line will let you get the offer and answer strings. Of course it still fails because Chrome doesn't support reliable data channels yet.

Thanks for the comment, @bscran. I don't get a PeerConnection even when running the source under "python -M SimpleHTTPServer 8080", even with unreliable data channels, so there's something about the ICE negotiation that needs to be fixed up before we get to these other problems.

Hi,
I also created a similar serverless WebRTC test site for my learning curve and others.

http://webrtcdevelop.appspot.com/

My code works with Chrome with "reliable" DataChannel flag true.
I think the reason your code does not work with Chrome is
Line157
pc1.onconnection = handleOnconnection;

which never fired on Chrome

(cf.)
chrome RTCPeerConnection event not fire after connected
http://stackoverflow.com/questions/17784780/chrome-rtcpeerconnection-event-not-fire-after-connected

onconnection is not part of the interface in the latest standard, so that's probably why it's not implemented in Chrome: http://dev.w3.org/2011/webrtc/editor/webrtc.html#interface-definition.

The code in Firefox lists onconnection as a Mozilla extension: https://github.com/mozilla/mozilla-central/blob/master/dom/webidl/RTCPeerConnection.webidl#L98.

Having said that, I stack where DataChannel send never works with Firefox. Chrome works fine on the other hand.
I observe your code also fails with DataChannel send with Firefox.

Please investigate my code(only 150lines), and do you have any idea on these?
Thanks.

Looks like Chrome works here now, and Chrome/Firefox interop works too.
