How to get information from COM port in QT?

Question

Arduino

The point is. We transfer information from the RFID Arduino to the COM port. It is necessary to consider it and simply write it to a variable. I would be glad if there is a ready solution. If not, then at least in which direction to drip and what to smoke for this?

Answer 1

In Qt5, this is QSerialPort. In earlier versions, the operating system API is at your service.

Answer 2

I think that the article Arduino Host Client in C will be useful.
