DataChannel in libjingle

[Sergey Ryazanov]

Hi guys,

I'm trying to setup data channel to send messages between Chrome instances with libjingle.

Could someone of you help me to debug it?

What I'm doing:

1) Create a PeerConnectionFactory.

2) Then I create a peer connection with: 1) ICE servers ["stun:stun.l.google.com:19302"], mandatory constraints {kEnableRtpDataChannels: true}, no DTLS identity service.

3) Create a data channel.

4) Create offer/answer with constrains {kOfferToReceiveAudio: false, kOfferToReceiveVideo:false, kVoiceActivityDetection:false}

What I'm observing:

Data channel doesn't come to "writable" state. No error reported. It seems it's because Transport can't resolve remote candidates. Generated offer has one media stream (desc->number_of_mediasections() == 1) with no ICE candidates in this section (desc->candidates(0)->count() == 0).

May be I missconfigured the connection?
