Connected Event

Fired after a MQTTSN connection completes (or fails).

Syntax

type TConnectedEvent = procedure (
  Sender: TObject;
  StatusCode: Integer;
  const Description: String
) of Object;

property OnConnected: TConnectedEvent 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.
