onWrtcCmd()

wrtc.onWrtcCmd() is an event function called when user command has been received through RTCgate signaling channel.

You can use this event to take care of the incoming user command.

wrtc.onWrtcCmd(obj, msg)

• obj - object: either a call object (indicating sender used call.adv.sendWrtcCmd() to send) or the wrtc object (indicating sender used wrtc.adv.sendWrtcCmd() to send)
• msg - the wrtc message received through the data channel:
  • msg.from - addressName of sender
  • msg.cmd - the user command (string or JSON)

Ignored.

If sending client has sent {cmd: "ping"} using

call.adv.sendWrtcCmd({cmd: "ping"});

you will receive a wrtc.onWrtcCmd() call with {cmd: "ping"} in its msg.cmd argument. Then you can respond with {cmd: "pong"}:

  wrtc.onWrtcCmd= function(obj, msg) {
    if ((msg.cmd.cmd) && (msg.cmd.cmd == "ping"))
      if (obj.objType == "call")
        obj.adv.sendWrtcCmd({cmd: "pong"});
      else
        wrtc.adv.sendWrtcCmd(msg.from, {cmd: "pong"});
  }

wrtc.adv.sendWrtcCmd()

call.adv.sendWrtcCmd()
