Android Question Bluetooth AStream Problem

[GaNdAlF89]

Hi, I have a strange case during the reading of a qrcode. The string correspondig to the qrcode is

0990000001100200150092015091520150915001001151511192382

But when I read the qrcode, the string is broken in two parts (as follows in the code), and the AStreamReader_NewData is raised two times. Why this?

'Declarations
Dim BTAdminReader As BluetoothAdmin
Dim BTSerialReader As Serial
Dim AStreamReader As AsyncStreams
Dim BlueMacReader As String
Dim BluePortReader As Int

'Connection
BTSerialReader.ConnectInsecure(BTAdminReader,BlueMacReader,BluePortReader)
'Connect, Connect2 and Connect3 doesn't work

Sub BTSerialReader_Connected (Success As Boolean)

  If Success = True Then 'Succes is correctly True
    AStreamReader.Initialize(BTSerialReader.InputStream,Null,"BluetoothAStreamReader")
  End if

End Sub

Sub BluetoothAStreamReader_NewData (Buffer() As Byte)

    Dim bConv As ByteConverter

    Dim BluetoothReaderResponse As String
    BluetoothReaderResponse = bConv.StringFromBytes(Buffer,"UTF8")

    Log(BluetoothReaderResponse) '(***)

End Sub

'This is the result of (***)
099000
0001100200150092015091520150915001001151511192382

OR

09900000
01100200150092015091520150915001001151511192382

This is how network streams work. Messages can be split or merged.

This is exactly the purpose of prefix mode. Though you cannot use it in this case.
