Connected Event
Fired after a MQTTSN connection completes (or fails).
Syntax
typedef struct { int StatusCode; String Description; } TiotMQTTSNConnectedEventParams; typedef void __fastcall (__closure *TiotMQTTSNConnectedEvent)(System::TObject* Sender, TiotMQTTSNConnectedEventParams *e); __property TiotMQTTSNConnectedEvent OnConnected = { read=FOnConnected, write=FOnConnected };
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.
