Qt Serial Bus▲
The Qt Serial Bus API provides classes and functions to access the various industrial serial buses and protocols, such as CAN, ModBus, and others.
Getting Started▲
To use the module with CMake, use the find_package() command to locate the needed module components in the Qt6 package:
find_package(Qt6 COMPONENTS SerialBus REQUIRED)
target_link_libraries(mytarget PRIVATE Qt6::SerialBus)To use the module for building with qmake, add the module as a value of the QT variable in the project's .pro file:
QT += serialbusSupported Buses and Protocols▲

Logging Categories▲
The QtSerialBus module exports the following logging categories:
|
Logging Category |
Description |
|---|---|
|
qt.canbus |
Enables standard logging inside the Qt CAN Bus classes |
|
qt.canbus.plugins |
Enables low level logging inside the Qt CAN Bus plugin classes. To set logging for a specific plugin, use "qt.canbus.plugins.pluginname". e.g. "qt.canbus.plugins.socketcan". "qt.canbus.plugins*" affects all plugins. |
|
qt.modbus |
Enables standard logging inside the Qt Modbus classes |
|
qt.modbus.lowlevel |
Enables low level logging including individual packet content inside the Qt Modbus classes |
Logging categories can be used to enable additional warning and debug output for QtSerialBus. More detailed information about logging can be found in QLoggingCategory.
A quick way to enable all Qt Modbus logging is to add the following line to the main() function:
QLoggingCategory::setFilterRules(QStringLiteral("qt.modbus* = true"));Examples▲
