Connected Event

Fired after a MQTTSN connection completes (or fails).

Syntax

class MQTTSNConnectedEventParams {
public:
  int StatusCode();
  const QString &Description();
  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Connected(MQTTSNConnectedEventParams *e);

// Or, subclass MQTTSN and override this emitter function.
virtual int FireConnected(MQTTSNConnectedEventParams *e) {...}

Remarks

If no will topic or message is set, this event will fire immediately. If a will topic and the will message are set, this event will be fired after the will packet exchange.

If the connection is made normally, StatusCode is 0 and Description is "OK".

Please refer to the Error Codes section for more information.

Refer to the Connected property for more information about MQTT-specific behavior.
