Sfs2X.Core.EventDispatcher:DispatchEvent(BaseEvent)
Sfs2X.SmartFox:ProcessEvents()
SFS2X_Connect:Update() (at Assets/SFS2X_Connect.cs:37)

connection code is shown below

public class SFS2X_Connect : MonoBehaviour {

    public string ServerIP = "xxx.xxx.xxx.xxx";
    public int ServerPort = 9933;

    SmartFox sfs;

    void Start () {
        sfs = new SmartFox ();

        sfs.ThreadSafeMode = true;

        sfs.AddEventListener (SFSEvent.CONNECTION, OnConnection);

        sfs.Connect (ServerIP, ServerPort);

    }

    void OnConnection(BaseEvent evt)
    {
        if ((bool)evt.Params ["success"]) {
            Debug.Log ("Successfully Connected");
        } 
        else {
            Debug.Log ((string)evt.Params["errorMessage"]);
        }
    }

    void Update () {
        sfs.ProcessEvents();

    }

}

Create a ConfigData then pass it to sfs for connection :

    ConfigData cfg = new ConfigData();
    cfg.Host = "x.x.x.x";
    cfg.Port = 9932;
    cfg.Zone = loginZone;
    cfg.Debug = true;
    smartFox.Connect(cfg);
