B4J Question How do I create an asynchronous stream to receive data from an device

[davepamn]

I need to port my B4A asychronous stream code to the b4j window socket with an asychronous stream handler for receiving data on a specific ip address. How do I create a second window socket connection and handle the incoming data stream?

B4A code:

Dim ast AsAsyncStreamsText

If ast.IsInitialized Then ast.Close

ast.Initialize(Me, "ast", serial1.InputStream, serial1.OutputStream) 'Needed! initialize AsyncStreamsText with the socket streams.



Sub ast_NewText(Text As String)

txtData.text=Text

End Sub

What do you mean with window socket? A tcp socket? Use jNetwork. It is exactly the same as in B4A.

Yes
Will you provided a link to the winsocket tutorial, I should follow? I used asychrononous streams not win socket for b4a

AsyncStreams never work on its own.

Two examples:

https://www.b4x.com/android/forum/t...d-and-receive-objects-over-the-network.34612/ (as written in the tutorial it will be simpler to use B4XSerializator)

 

[davepamn]

Correct
I use the asychrononous streams with a serial communication object in b4a

I need to explore the winsocket callback functions for b4j

 

[Erel]

I see. You are talking about the serial ports. See jSerial library: jSerial library

How does win socket and serial communication work together? Are they two separate ways to talking with the device?
