Hi folks, I've tried to modify the "SerialSample" to use two stop bits instead of the default configuration in a RaspberryPI 3 Model B and any value different from "SerialStopBitCount.One" throws an exception as below: `'serialPort.StopBits = SerialStopBitCount.Two' threw an exception of type 'System.ArgumentException' Data: {System.Collections.ListDictionaryInternal} HResult: -2147024809 HelpLink: null InnerException: null Message: "Value does not fall within the expected range." ParamName: null Source: "Windows" StackTrace: " at Windows.Devices.SerialCommunication.SerialDevice.put_StopBits(SerialStopBitCount value)"` My understanding is that it's not allowing any "non-zero' value (SerialStopBitCount.One = 0, SerialStopBitCount.OnePointFive = 1 and SerialStopBitCount.Two = 2). Anyone else have faced the same issue before? Can someone try to reproduce it? Entire function source code as reference: ``` private async void comPortInput_Click(object sender, RoutedEventArgs e) { try { string aqs = SerialDevice.GetDeviceSelector("UART0"); /* Find the selector string for the serial device */ var dis = await DeviceInformation.FindAllAsync(aqs); /* Find the serial device with our selector string */ serialPort = await SerialDevice.FromIdAsync(dis[0].Id); /* Create an serial device with our selected device */ if (serialPort == null) return; // Disable the 'Connect' button comPortInput.IsEnabled = false; // Configure serial settings serialPort.WriteTimeout = TimeSpan.FromMilliseconds(1000); serialPort.ReadTimeout = TimeSpan.FromMilliseconds(1000); serialPort.BaudRate = 38400; serialPort.Parity = SerialParity.None; serialPort.StopBits = SerialStopBitCount.Two; // THIS LINE THROWS AN EXCEPTION serialPort.DataBits = 8; serialPort.Handshake = SerialHandshake.None; // Display configured settings status.Text = "Serial port configured successfully: "; status.Text += serialPort.BaudRate + "-"; status.Text += serialPort.DataBits + "-"; status.Text += serialPort.Parity.ToString() + "-"; status.Text += serialPort.StopBits; // Set the RcvdText field to invoke the TextChanged callback // The callback launches an async Read task to wait for data rcvdText.Text = "Waiting for data..."; // Create cancellation token object to close I/O operations when closing the device ReadCancellationTokenSource = new CancellationTokenSource(); // Enable 'WRITE' button to allow sending data sendTextButton.IsEnabled = true; Listen(); } catch (Exception ex) { status.Text = ex.Message; comPortInput.IsEnabled = true; sendTextButton.IsEnabled = false; } } ``` Thanks in advance!
