Android Question AsyncStreams Prefix

[Feathers]

Hello,
I am not able to read received data in AsyncStreams Prefix mode, it works in non Prefix mode(breaks data up as expected), I wish to use Prefix mode.
An example of data being sent including prefix
0011/:A-12500:\

Sub seriall_Connected (Success As Boolean)
    ProgressDialogHide
    Log("Connected: " & Success)
    If Success = False Then
        Log(LastException.Message)
        ToastMessageShow("error connecting: " & LastException.Message,True)
        timer1.Enabled = False
    Else
       'AStreams.Initialize(seriall.InputStream, seriall.OutputStream, "AStreams")
        AStreams.InitializePrefix(seriall.InputStream, True, seriall.OutputStream, "AStreams")
        If AStreams.IsInitialized = True Then Log("OK")

        btnScan.Visible = False
        timer1.Enabled = False
        'StartActivity (displayData)
    End If
End Sub
   
Sub AStreams_NewData (Buffer() As Byte)
    Dim msg As String
    msg = BytesToString(Buffer, 0, Buffer.Length, "UTF8")
    ToastMessageShow(msg, False)
End Sub

Any suggestions appreciated.

Prefix mode can only work if both sides of the connection use the "prefix" protocol. What is running on the other side?

Hello Erel

The data is sent via BT from Atmel micro, I can control what is sent.
Android device only needs to receive data, no transmission necessary.
Is the format 0011/:A-12500:\ for prefix & data not correct?

No.
The protocol is explained in the tutorial: https://www.b4x.com/android/forum/threads/asyncstreams-tutorial.7669/

It will be easier to use AsyncStreamsText and add an end of line character to each message.
