The Sending Data is not Write to Arduino and Controller

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.
