[solved]how I can send multiply commands through serial interface using QByteArray

[reem9611]

Hi,
I am using Qt to creat a GUI to communicate with X device through RS232

I use QByteArray to send a single request to x device

@void SerialCom::onSendButtonClicked()
{

if (port->isOpen());

QString r= ui->comboBox->currentText();

if(R=="XXXX"){
    
    QByteArray msg("00RS\r\n"); 
    port->write(msg);

}@

I have a list of commands to initialize the sensor setting and I have to send all these commands in one function.
My Question is how I can send multiply commands through serial interface ( example of the command to be send ->"00RS\r\n") ?! is it right to create QByteArray for each command ?

Hi,

Why not build a complete list of command first and then send everything at once ?

how to do that can you please give me an example or any keyword so I can search about that and implement it in my code .
