PySide6 missing QtSerialBus, modbus

AndrzejK

Hi,
How to check this example?

https://doc-snapshots.qt.io/qtforpython-dev/examples/example_serialbus_modbus_modbusclient.html

I see that PySide6 not include package QtSerialBus (file mainwindow.py in example)

from PySide6.QtSerialBus import (QModbusDataUnit,                                                                                                       
                                 QModbusDevice, QModbusReply,                                                                                           
                                 QModbusRtuSerialClient, QModbusTcpClient)

Any idea how to install missing QtSerialBus for Python?

@AndrzejK What about pymodbus

I don't think QtSerialBus for python will be released, but I may be wrong. Otherwise you may need to wrap C++ QtSerialBus module to python by yourself using shiboken, but that will be not be simple.

Seems it's not available for python. Probably they didn't have included it as it is a standard and I guess everything you need is already provided by python libraries. Maybe you can try with python-can .

@Gojir4 I can't use CAN. I need Modbus.
I researched that package Qt Modbus from Qt work for C++ solution but for Python is missing.

@Gojir4 Thank you. I will check pymodbus.
You are right, wrap C++ QT Serial Bus to Python is not simple.
