Hi,

when i set in the sub Serial_Connected
AStream.InitializePrefix(serial.InputStream,False,serial.OutputStream,"AStream")
the programm stopps

Private Sub Serial_Connected (Success As Boolean)
   If Success Then
     
     If AStream.IsInitialized Then AStream.Close
     AStream.InitializePrefix(serial.InputStream,False,serial.OutputStream,"AStream")
   
     Log("Connected")
     connected = True
     
   Else
     Log(LastException)

Are you using B4R to program the Arduino?

YES,
but the problem is on the b4A-side, to initialize
AStream.InitializePrefix and how to watch the bluetooth-connection

You should check the logs and post the error message.

how to watch the bluetooth-connection

Handle AsyncStreams Error and Terminated events.

You should check the logs and post the error message.


Handle AsyncStreams Error and Terminated events.

The Error message is:
java.io.IOException: Service discovery failed

This error has nothing to do with AsyncStreams. The serial connection has failed.
