What version of the product are you using? On what operating system? Windows 8 x64 Flash Builder 4.6

Source . .

protected function windowedapplication1_creationCompleteHandler(event:FlexEvent):void { arduino = new ArduinoConnector(); arduino.addEventListener("socketData",onSocketData); arduino.connect("COM7",9600);

            txtOutput.appendText("Connecting")

        }

        protected function onSocketData(event:ArduinoConnectorEvent):void
        {
            var ba:ByteArray;
            arduino.removeEventListener("socketData",onSocketData);
            ba = arduino.readBytesAsByteArray();
        }

Same here this happends when using readBytesAsByteArray() readBytesAsString() works fine

Win 7 x64
