Signal taking very long

See original GitHub issue

I’m having some issues with the signaling phase, as it takes randomly a really long time (> 10 sec) or, worse, it never actually gets any data.

Basically, I’m following the basic tutorial, and then I’m doing this:

peer.on('signal', data => {
  console.log('data', data);
  // omitted
});

For testing I’m using the Stun server from Google. In production I will rely on another more reliable stun server (as it is suggested not to use the one by Google in production).

I have also tried with some other stun servers from the following list. Unfortunately the problem persists.

With trickle set to false, I get the following messages in the console of the initiator:

[2018-11-16T15:32:28.988Z] SimplePeer debugger: "starting batched negotiation"
[2018-11-16T15:32:28.989Z] SimplePeer debugger: "start negotiation"

[2018-11-16T15:32:29.002Z] SimplePeer debugger: "iceStateChange (connection: %s) (gathering: %s)"

And most of the times it won’t proceed further as no code is retrieved from the signal event.

With trickle set to true, in the console of the initiator I get this:

                        - eventNames: undefined.

In this second scenario there are a couple of things that I do not totally get, in particular why do I see the connect event in the SimplePeer debug messages, but then if I log the peer Object it states connected: false?

The fix we added is an ice gathering timeout that only works when trickle is disabled. We’re aware of the limitation for now.

I’m happy to confirm that with trickle set to false with the latest code (from github) it’s working again!

I still get the issue mentioned before with trickle set to true (connect event fired when receiver is not actually connected yet). Should I open a new issue or is this one fine?
