Sub AStream_Error
'ToastMessageShow("Connection is broken.", True)
ToastMessageShow(LastException.Message, True)
btnSend.Enabled = False
txtInput.Enabled = False

Are you initializing AsyncStreams in Prefix mode (you shouldn't)?

Hi Erel
I use this part of software as is in example
Is it OK ??

"Sub Activity_Create(FirstTime As Boolean)

Activity.LoadLayout("2")
If AStream.IsInitialized = False Then
AStream.InitializePrefix(Main.serial1.InputStream, True, Main.serial1.OutputStream, "AStream")
End If
txtLog.Width = 100%x
End Sub"
