GatewayInfo Event

Fired when the component receives a GWINFO or ADVERTISE packet.

Syntax

typedef struct {
  String MessageType;
  int GatewayId;
  String GatewayAddress;
  int Interval;
} TiotMQTTSNGatewayInfoEventParams;

typedef void __fastcall (__closure *TiotMQTTSNGatewayInfoEvent)(System::TObject* Sender, TiotMQTTSNGatewayInfoEventParams *e);

__property TiotMQTTSNGatewayInfoEvent OnGatewayInfo = { read=FOnGatewayInfo, write=FOnGatewayInfo };

Remarks

This event allows packets containing gateway information to be processed. These packets could be received from regular gateway advertisements or gateway info requests from this or other clients. This gateway information is used to manage the client's list of active gateways.

The value of MessageType could be GWINFO or ADVERTISE.

GatewayAddress will be in format host:port.

If the gateway address field is not present in the received GWINFO packet, GatewayAddress will use the packet source IP address.

This functionality is not yet implemented.
