Hi @teddybear and fellow members,

Refer to this library:

[B4J]jMQTTBroker v2 added the onConnect and onDisconnect for broker interceptor

For this and that reasons. I modified the library jMQTTBroker v2 and added raising onConnect and onDisconnect events for broker interceptor. Broker example is from Erel's this code. Library source code is attached.
www.b4x.com

I want to know:
  1. Is this a replacement of jMqttBroker v1.04 and v2.02?
  2. Does this mean I no longer need to add an MqttClient to get the events like Connected, Disconnected, MessageArrived?
  3. Is this library still work if use together with MqttClient library?
  4. Which version of MqttClient library is supported for B4A and B4J? version 1.26?
 
Solution
1.No, it just added onConnect and onDisconnect events for jMqttBroker2.
2.No, it's only on broker side.
3.Yes
4.Version 1.26 is supported.

Yes, the example is from Erel's code
Actually, you also add the handler dynamically after the broker started

Another way to add Interceptor.

B4X: 
    Broker.Initialize("broker", 51042)
    Broker.Start
    Dim server As JavaObject = Broker.As(JavaObject).GetField("server")
    Dim pck As String = GetType(Me) & "$MyHandler"
    Dim handler As JavaObject
    handler.InitializeNewInstance(pck, Array(Me))
    server.RunMethod("addInterceptHandler", Array(handler))
