PySide6.QtBluetooth#

Detailed Description#

Qt Bluetooth enables connectivity between Bluetooth enabled devices.

The Bluetooth API provides connectivity between Bluetooth enabled devices.

Currently, the API is supported on the following platforms:

Bluetooth LE Advertisement & Scanning

Qt 5.14 adds a native Win32 port supporting Classic Bluetooth on Windows 7 or newer, and Bluetooth LE on Windows 8 or newer. It must be enabled at build time by configuration option -native-win32-bluetooth. The UWP backend is used by default if this option is not set and the Win32 target platform supports the required UWP APIs (minimal requirement is Windows 10 version 1507, with slightly improved service discovery since Windows 10 version 1607).

Overview#

Bluetooth is a short-range (less than 100 meters) wireless technology. It has a reasonably high data transfer rate of 2.1 Mbit/s, which makes it ideal for transferring data between devices. Bluetooth connectivity is based on basic device management, such as scanning for devices, gathering information about them, and exchanging data between them.

Qt Bluetooth supports Bluetooth Low Energy development for client/central role use cases. Further details can be found in the Bluetooth Low Energy Overview section.

Using the Module#

To include the definitions of modules classes, use the following directive:

import PySide6.QtBluetooth

macOS Specific#

The Bluetooth API on macOS requires a certain type of event dispatcher that in Qt causes a dependency to QGuiApplication . However, you can set the environment variable QT_EVENT_DISPATCHER_CORE_FOUNDATION=1 to circumvent this issue.

Applications that don’t use Classic Bluetooth will find a subset of QtBluetooth is available, as CoreBluetooth (Bluetooth LE) do not require either of QApplication or QGuiApplication .

Logging Categories#

The QtBluetooth module exports the following logging categories :

Logging Category

Description

qt.bluetooth

Enables logging of cross platform code path in QtBluetooth

qt.bluetooth.android

Enables logging of the Android implementation

qt.bluetooth.bluez

Enables logging of the BLuez/Linux implementation

qt.bluetooth.ios

Enables logging of the iOS implementation

qt.bluetooth.osx

Enables logging of the macOS implementation

qt.bluetooth.windows

Enables logging of the Qt for Windows implementation

Logging categories can be used to enable additional warning and debug output for QtBluetooth . More detailed information about logging can be found in QLoggingCategory . A quick way to enable all QtBluetooth logging is to add the following line to the main() function:

QLoggingCategory.setFilterRules("qt.bluetooth* = true")
