Hmmm, I'm not sure, I'll have a look at this in the next week and get back to you.
I haven't found a solution yet, but here's what I have so far:
The sdp from FF is not being accepted by Chrome. This could be due to how P is constructing this from the FF side.
Here's the SDP Chrome sends (which works with P):
v=0
o=- 6482952298957471473 2 IN IP4 127.0.0.1

Here's the one that Firefox sends (which doesn't work):

s=SIP Call

do you know why this happens? I'm having a hard time getting plink + plink-server working in Firefox. RTCPeerConnection
keeps emitting closed
event.
I'm loading both peers from Firefox.
Still unable to stop peers from getting disconnected in Firefox. Do we know if this is a bug in p
or onramp
? Is there some place in particular I should be looking at?
Sorry about the late response. I think I'll some time to take a look at this on Saturday. I think the last time I investigated this I was suspecting that maybe I was sending the request too soon (without first attaching ICE candidates). I don't think this is a problem in onramp, onramp is pretty dumb code-wise, it's likely in the WebRTCConnection
module of p
@oztu did you have any luck debugging this?
First off, thank you for being persistent. I don't have much motivation to update this code since I'm not actively using it on a project, so I wouldn't take time to address these issues if I weren't reminded (I really do keep forgetting to address them, it's not because I don't want to).
This was a tricky bug to hunt down. I think this may be an exotic case of FF eagerly cleaning up references during GC it should not be (see a similar issue reported here: https://code.google.com/p/webrtc/issues/detail?id=2047). I was unable to find a FF bug ticket, I may file one if I can reduce this to a simpler case to present. I added a hard reference to each of the objects involved which will prevent them from being caught in GC, this should resolve your problem you're experiencing.
I also found that the standard has evolved quite a bit since I've written the code last year. I've updated the places I found to be behind so this should fix other misc. errors due to divergence in the APIs.
If you have problems in the future I added a logger which can be enabled by setting window.P_DEBUGGING_ENABLED = true
before loading p.js -- it'll output a whole lot more to the console to help in debugging/bug reports.
Please let me know if the new version (v0.3.3) resolves your issue, thanks!
Thanks for taking a look and fixing - I really appreciate it. And apologies for persistence, heh - I totally understand.
Still following! Super you did find some time. Gonna try now.

I did build a P2P datasharing system with "P", using Chrome as testbrowser. This is ment for very fast distributing short and realtime messages with a few feeding servers in the network. (P2P flooding)
On some point, it worked so well that browser testing was the next step.
Chrome : OK Opera : OK Chrome on android : OK! Latest firefox : disconnects after apr. 1 second

Any idea? Did something change in FF...
