Android Question MsgboxAsync with AsyncStreams object

[GaNdAlF89]

Hi to all!
I need to connect to a physical (with laser) barcode reader via bluetooth, and I receive the barcode read using the AsyncStreams object. I need a MsgboxAsync inside both the "AsyncStreamReader_NewText (strBuffer As String)" and "AsyncStreamReader_Error" events.
Since these are events not related to an user interaction (the barcde reader is always active, in an entrance door, but when it reads a barcode, an operator have to make a decision), how can I do to make "As Resumable" both the _NewText and _Error events? Thank you.

Current code:

Sub BTSerialReader_Connected (Success As Boolean)
    If Success=True Then
       BTAsyncStreamReader.Initialize(Me,"BluetoothAsyncStreamReader",BTSerialReader.InputStream,BTSerialReader.OutputStream)
       'etc
End Sub

Sub BluetoothAStreamReader_NewText (strBuffer As String)
    Dim TipoMov As List
    TipoMov.Initialize2(Array As String("In","Out"))
       
    Dim ro As Object = InputListAsync(TipoMov,"Seleziona tipologia di...",-1,False)
    Wait For (ro) InputList_Result (res As Int)
    If res = 0 Then
        'etc...
End Sub
Sub BluetoothAStreamReader_Error
     MsgboxAsync("Reading error...","Attention")
     Wait For Msgbox_Result (res As Int)
End Sub

You cannot wait for two different events at the same point.

You can do something like this:

Sub BTSerialReader_Connected (Success As Boolean)
    If Success=True Then
       BTAsyncStreamReader.Initialize(Me,"BluetoothAsyncStreamReader",BTSerialReader.InputStream,BTSerialReader.OutputStream)
        Wait For MyNewText (Success As Boolean, Text As String)
         'do whatever you need here
End Sub

Sub BluetoothAStreamReader_NewText (strBuffer As String)
 CallSubDelayed3(Me, "MyNewText", True, strBuffer)
End Sub

Sub BluetoothAStreamReader_Error
CallSubDelayed3(Me, "MyNewText", False, "")
End Sub

Thanks for the reply. Meanwhile I thought at this solution:

Sub BTSerialReader_Connected (Success As Boolean)

    If Success=True Then

       BTAsyncStreamReader.Initialize(Me,"BluetoothAsyncStreamReader",BTSerialReader.InputStream,BTSerialReader.OutputStream)
       'nothing else here
  
End Sub

Sub BluetoothAStreamReader_NewText (strBuffer As String)

    Wait For BluetoothAStreamReader_MyResponse(True,strBuffer) Complete (Result As Object)

End Sub

Sub BluetoothAStreamReader_Error

    Wait For BluetoothAStreamReader_MyResponse(False,"") Complete (Result As Object)

End Sub

Sub BluetoothAStreamReader_MyResponse (Success As Boolean, Text as String) As Resumable
  
    'my prevoius code from _NewText and _Error, based on Success...
  
    Return Null
End Sub

Is it correct?

1. ResumableSub not Resumable.
2. Why call it with Wait For, if you are not doing anything after the Wait For line? Just call it like you call a regular sub.
