Connected Event
Fired after a MQTTSN connection completes (or fails).
Syntax
mqttsn.on('Connected', listener: (e: {readonly statusCode: number, readonly description: string}) => void )
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.
