Android Question Is there a Winsock1 control similar to VB6.0 in B4A?

I need to monitor and obtain the content read by the WIFI fixed code reader... Thank you everyone!

What is the WIFI fixed code reader? is it OBD?

What is the WIFI fixed code reader? is it OBD?

This is a fixed barcode reader that reads the barcode content and sends it out through the WIFI port. The receiving end listens to the content sent from this port and displays it in a text box

I think you may need to build a server or use mqtt protocol

[WebApp] Web Apps Overview

B4J v2.00 adds support for web applications based on WebSocket technology. With WebSocket The browser and the server maintain an open communication channel. This channel allows us to build web apps where all (or most) of the logic is implemented in the server. The new framework is implemented...

’listening
Private Sub Winsock1_ConnectionRequest(ByVal requestID As Long)
If Winsock1.State <> sckClosed Then Winsock1.Close
Winsock1.Accept requestID
End Sub
‘get
Dim strData As String
Winsock1.GetData strData

In VB6.0, I used Winsock components to implement listening and content retrieval. I am not sure if there are similar components or related cases to use in B4A for reference.

        Client.Initialize("Client")
        Client.Connect("192.168.0.10", 35000, 10000)

Most OBD wifi (if thats what you are implying) uses the above ip address and port number.

In Client success connection add

AStreams.Initialize(Client.InputStream, Client.OutputStream, "AStreams")

Aha, this is a great case of cheating, haha。。。

In this example, I have successfully connected the code reader through IP and port number. Next, I would like to obtain the content read by the code reader and display it on Lable1.text. How can I implement this? Thank you!

Better to start a new thread and provide more information.
