QSerialPort::SerialPortError(PermissionError)
-
I am trying to open the connection for reading and writing (I am working on Windows) but the program says that I have no permission and I don´t know how to open it. I have tried running as administrator but it doesn´t work.
Here I post which part of code give me the error
if (!serial.open(QIODevice::ReadWrite)) {
qDebug("SERIAL PORT - NOT OPENED") ; qDebug()<<"error code = "<<serial.error(); processError(tr("No puedo abrir el puerto %1, error code %2") .arg(serial.portName()).arg(serial.error())); return;}

@kar95 give us some more Information about the code before the error where you set the port name, baudrate parity etc.
Also a serial port my only have one open connecten across your operating system. If you have an other program that is accessing the port, opening it will always fail.
