QSerialBus included in QT6?

[LouieLoay]

is QSerialBus included in QT6? i noticed it is listed in the "Addons" section of the website, does this mean it is purchased separately?

@LouieLoay it should be part of Qt6
https://doc.qt.io/qt-6/qtmodules.html

what version of Qt 6 are you using, IIRC it was not part of the early releases.

hi @J-Hilk,

i only have the open source version 5.5.1

i am looking to buy the enterprise version as a small business. i sent an inquiry to about eligibility but have not received a response.

I have a small project that needs ModBus communications. i believe QSerialBus supports ModBus and CANBUS. is that correct?

before i purchase the software i wanted to make sure that QSerialBus is included and that ModBus TCP comms is supported.

@LouieLoay According to https://doc.qt.io/qt-6/qtserialbus-changes-qt6.html QSerialBus is part of Qt 6.3.0

[J.Hilk]

@LouieLoay Qt is open source (currently) until and including Version 5.15.3 and 6.4

Qt does also provides Modbus

and can bus

classes for you to use.

@LouieLoay
That only tells you what your Qt Creator IDE version is, and what version of Qt it uses internally. You need to look at what version of Qt itself you are using for compiling/running your code, which may not be the same.

Having said that, your Creator is a pretty old version (5.5/2015), so that might be indicative you also use an old-ish version of Qt. I do not know at which version of Qt support for ModBus/CANBUS was introduced. Whichever route you go, you are likely to want a newer version of Qt than 5.5.
