Question

When I go into the serial settings, the serial connection is closed. If I select the wrong baud rate for the serial coming in the app freezes and I can’t even get any debug since it is still working but I am unsure what it is doing.

Ultimately, my question is how to check if the baud rate selected is correct and how to make sure the serial does not freeze my application.

Answer 1

I finally got it to throw an error. When it is trying to call sp.ReadLine(); it says that ReadLine() has timed out. I have the timeout at 500.

I just used:

try {
  data = sp.Readline();
}
catch (TimeoutException errorEvent)
{
  //Write to console the errorEvent (This operation has timed out)
  //Message to user to pick correct baud
  tbConsole.AppendText(Environment.NewLine);
  tbConsole.AppendText("Incorrect Baud Rate: Please select a new baud rate");
  tbConsole.AppendText(Environment.NewLine);
  tbConsole.AppendText(errorEvent.Message);
  tbConsole.ScrollToEnd();
  //Show baud rate settings dialog
}
