      Hi,

      If you are thinking about on_send_clicked then at no point are you triggering anything that will write to any of the serial ports.

      Also, each time you call on_openbutton_clicked you create two new QSerialPort objects without even cleaning the old ones.

      And there's absolutely no need for these toStdString/fromStdString conversions.
