Issue receiving data weighing scale Ohaus aviator 7000

Yina

Hello

I am trying to establisch a serial port connection to my Aviator 7000 weighing scale. The expected result would be a succesfull communication through the use of a byte command.
Sadly I don't receive any bytes back from the scale. below you can find what I tried so far:

        const int Max_attempts = 5;
        const int Max_sleep = 125;

        int attemps;
        attemps = 0;
        while (true)
        {

            int enq {5};
            QByteArray bytes;
            bytes.setNum(enq);
            m_serial->write(bytes);

            m_serial->waitForReadyRead(Max_sleep);

            if (m_serial->bytesAvailable() !=0)
            {
                qDebug() << m_serial->bytesAvailable() ;
                qDebug() << "connected" << m_serial->readAll();
                break;
            }

            attemps += 1;

            if (attemps == Max_attempts)
            {
                qDebug() << "no connection established";
                break;
            }
        }

Kind regards,

The issue was that it had to be byte \x05 and QByteArray.setnum(5) will result in \x35 so I had to use QByteArray::append()

Hi,

How are you connecting to that scale ?
Physical cable ?
Can you connect to it by another program ?
Which OS are you running ?
Which Qt version are you using ?
