Unable to read from QSerialPort using MSVC compiler

@Turi said in Unable to read from QSerialPort using MSVC compiler:
I have already followed the suggestions of @J-Hilk
No, I was refering to this:
"also connect to the error signal errorOccured
https://doc.qt.io/qt-5/qserialport.html#errorOccurred"And you should use the Qt5 connect syntax: https://doc.qt.io/qt-5/signalsandslots.html

I have already tried all this and all seem work fine, without any error. But my application still does not read from the serial only if I use the MSVC compiler. -

@Turi what versions are we actually talking here ?
Qt(from the kit), msvc, windows etc.
and can you show more of your actually class that does the serial communication?

@J-Hilk
I'm using:- Qt Creator 4.9.0
- Based on Qt 5.12.2 (MSVC 2017, 32 bit)
- Windows 10 Enterprise
Unfortunately I can't show more of my actually class due to the fact that is reserved code.

This is the Qt version which was used to build QtCreator.
What Qt version do you use? -

Can you pass me a link where I can download this version?
Use the Qt Maintenance Tool to add that Qt version to your installation.

There was a bug with QSerialPort on Windows but IIRC it has been also fixed for the 5.12 series if you really need it. But you have to update to the latest release of that series.
