QserialPort and QTcpSocket, led to a difference in the QByteArray sent through them

[kuzulis]

Check returns value from

setDataBits(QSerialPort::Data8)

setDataBits(QSerialPort::Data8)

To copy to clipboard, switch view to plain text mode 

at successful should be "true".

[cstr]

Is true.

Thank you kuzulis.

[kuzulis]

Is true.

It is strange. Give a code where you configure and open port.

[cstr]

SettingsDialog::Settings s = settingsDialog->settings();
        serial->setPortName(s.name);
        serial->open(QIODevice::ReadWrite);
        if (!serial->setBaudRate(s.baudRate)
                && serial->setDataBits(s.dataBits)
                && serial->setParity(s.parity)
                && serial->setStopBits(s.stopBits)
                && serial->setFlowControl(s.flowControl))
            return; // Failed

SettingsDialog::Settings s = settingsDialog->settings();
        serial->setPortName(s.name);
        serial->open(QIODevice::ReadWrite);
        if (!serial->setBaudRate(s.baudRate)
                && serial->setDataBits(s.dataBits)
                && serial->setParity(s.parity)
                && serial->setStopBits(s.stopBits)
                && serial->setFlowControl(s.flowControl))
            return; // Failed

To copy to clipboard, switch view to plain text mode 

[kuzulis]

Please replace part of code to:

bool success = serial->open(QIODevice::ReadWrite)
&& serial->setBaudRate(s.baudRate)
&& serial->setDataBits(s.dataBits)
&& serial->setParity(s.parity)
&& serial->setStopBits(s.stopBits)
&& serial->setFlowControl(s.flowControl);
 
if (!success ) {
return; // Failed
}

bool success = serial->open(QIODevice::ReadWrite)
&& serial->setBaudRate(s.baudRate)
&& serial->setDataBits(s.dataBits)
&& serial->setParity(s.parity)
&& serial->setStopBits(s.stopBits)
&& serial->setFlowControl(s.flowControl);

if (!success ) {
return; // Failed
}

To copy to clipboard, switch view to plain text mode 

and check now.

[cstr]

Still true.

Thank you kuzulis.

[kuzulis]

In this case, check the correctness of installation of databits in DCB in debugger after setDataBits() call.

[cstr]

My fault! Everything is working now. May be a full rebuild/make was required to effectively apply the setDataBits.

Sorry.
