Detailed Description

Bluetooth manager.

The entry point to communicate with system BlueZ daemon.

The typical usecase is to work with usableAdapter() (any powered adapter), but it is also possible to use specific adapter.

You must call init() before other functions can be used.

The only functions that can be used before initialization are two rfkill-related functions: isBluetoothBlocked() and setBluetoothBlocked().

Example use in C++ code:

BluezQt::Manager *manager = new BluezQt::Manager();
BluezQt::InitManagerJob *job = manager->init();
job->start();
connect(job, &BluezQt::InitManagerJob::result, ...);

In QML, manager is a singleton and initialization is started when first using the manager. You don't need to track initialized state, just use property binding.

Example use in QML code:

import QtQuick
import org.kde.bluezqt as BluezQt
 
Item {
    readonly property BluezQt.Manager manager: BluezQt.Manager
    property devicesCount: manager.devices.length
    property adaptersCount: manager.adapters.length
 
    Component.onCompleted: {
        console.log("Manager operational:", manager.operational)
    }
}

Note: All communication with BlueZ daemon happens asynchronously. Almost all methods returns PendingCall to help track the call progress and to check for any errors.; If manager is not operational, all methods that returns a PendingCall will fail with PendingCall::InternalError.

signal

Indicates that at least one of the device's properties have changed.

◆ deviceForAddress()

DevicePtr Manager::deviceForAddress ( const QString & address ) const

Returns a device for specified address.

Note: There may be more devices with the same address (same device in multiple adapters). In this case, the first found device will be returned while preferring powered adapters in search.

Parameters

address address of device (eg. "40:79:6A:0C:39:75")

Returns: null if there is no device with specified address

Definition at line 110 of file manager.cpp.

◆ deviceForUbi()

DevicePtr Manager::deviceForUbi ( const QString & ubi ) const

Returns a device for specified UBI.

Parameters

ubi	UBI of device (eg. "/org/bluez/hci0/dev_40_79_6A_0C_39_75")
