cgxWP4Wu77s The purpose of this tutorial is to cover the various communication options available for B4X developers. Will start with two important utilities: AsyncStreams: Asynchronously reads and writes to any stream and avoids blocking the main thread. Do not assume that messages will arrive as

It is a class: AsyncStreamsText - Useful when working with streams of text
link: Never mind. I have figured out it is not a library. Show's how new I am at B4J. I used B4A about a decade ago for one bluetooth but so much has change
link: I thought it was part of the RandomAccessFile library. Have you found it somewhere else?
link: Where can I find the AsyncStreamsText library? I can only find references to it. I'm just learning B4J and want to use a serial port. Thanks

AsyncStreamsText relies on having end-of-line characters - ie CHR(13) and/or CHR(10) - to mark the end of a packet line, and thus won't work for your data which is fixed-length packets with no end-of-packet marker.
link: Presumably this: class asyncstreamstext useful when-working with streams of text Which would work great with the example incoming data, if that data
link: sorry it does not work, on my side I managed to have it. Now I have the full string but I don't understand how to dump if I take sb.Length or buffer.L
link: I meant something else. Erel wrote a small source to avoid this problem. Unfortunately I can't find it now. The concept was that each end of string p

The purpose of AsyncStreamsText is to collect the data from multiple packets and find complete messages. You shouldn't assume that the data arrives in a single packet. So your code is not correct. You should wait for NewText to be raised and only then you know that a complete message was received.
link: I am running AsyncStreamsText classes on an internal network (TCP/IP) and I would say that all of my communications end with the "_Terminated" event b
link: There is no timeout. The event is raised when the other side has closed the connection.

Hello friends, This is my first but not last post in forum :D When I checked B4J_chat.zip file in Erel's post, I see that there is an old .fxml designer file that can not be recognized by B4J 9.8. I succeed to convert 1.fxml to 1.bjl file and succeed to make communicate Hercules (a terminal progra

Why use AsyncStreamsText? The simplest way is with AsyncStreams in prefix mode. Start with this example: Network + AsyncStreams + B4XSerializator
link: Hello udg, thank you for the welcome, and so fast!! I have used many languages over the years, all scientific including HPL from Hewlett Packard and
link: Hello thetahsk. Thank you taking the time to try and help me out. Yes, I saw the tutorial (and another about the AsyncStreams specifically) but none
link: For example, if I have 6 bytes being sent, do I send 0,0,0,6 in Big Endian or Little Endian? At the moment, I am not getting bytes across, but as the

AsyncStreamsText will cut the message here End Sub Sub AStream_NewData (Buffer() As Byte) For i = 0 To Buffer.Length - 2 Step 2 Dim ledNumber As Byte = Buffer(i) Dim value As Boolean = Buffer(i + 1) = 1 leds(ledNumber).DigitalWrite(value) Next End Sub
link: Sub Timer1_Tick astream.Write("Millis here: ".GetBytes) astream.Write(NumberFormat(Millis, 0, 0).GetBytes) astream.Write(Array As Byte(10)) 'end

This is an example of using low level network features to implement a high level protocol. It is an implementa

AsyncStreamsText is a code module. You can add it as is to B4J.
link: I've found reference in the forums to AsyncStreamsText which is exactly what I need, but having added jNetwork to my B4J project I can only appear to
link: Erel, Where can I find the code module AsyncStreamsText? Harry
link: Hello Harry, Here you go: https://www.b4x.-bas.24051/ If you search for AsyncStreamsText and then click on the thread that has the "B4A Library" tag

AsyncStreamsText.Write expects a string not an array of bytes.
link: Hi, My B4A program using asyncstreamstext writes a simple text: Main.Stream2.write("Start") to a B4J program also using asyncstreamstext. The error
