The usage of the dummy backend is highlighted via an appropriate warning while building and running. +\section3 Linux Specific + +Since Qt 6.5 the Linux peripheral support has two backend alternatives: +BlueZ DBus and Bluetooth kernel API. The Bluez DBus backend introduced in Qt 6.5 is +intended as the eventual successor of the lower abstraction level kernel backend. + +The BlueZ DBus API is more limited in terms of features and is therefore not +the default backend for compatibility reasons. + +The BlueZ DBus backend can be configured to use by setting +the \e QT_BLUETOOTH_USE_DBUS_PERIPHERAL environment variable. The QLowEnergyController +peripheral instantiation then introspects the presence of BlueZ DBus peripheral APIs +on the local bluetooth adapter. The minimum version requirement for BlueZ is 5.56. + +One noteworthy difference is that with BlueZ DBus peripheral backend the user process no longer +needs to have the \e CAP_NET_ADMIN capability (eg. run as root). + \section3 \macos Specific The Bluetooth API on \macos requires a certain type of event dispatcher that in Qt causes a dependency to \l QGuiApplication.
