Detailed Description

The Bluetooth settings contain information about the local Bluetooth device, such as the device model and whether the device is powered on and available for connections with other Bluetooth devices.

The Bluetooth device can scan for other Bluetooth devices in range and retrieve information about them. The Bluetooth device then uses the address of another device to attempt pairing to it, and connects to it if the pairing was successful.

Member Function Documentation

BluetoothDevice::BluetoothDevice(QObject *parent = Q_NULLPTR)

Creates a new Bluetooth device with the parent parent.

bool BluetoothDevice::available() const

Returns the availability of the Bluetooth device.

Note: Getter function for property available.

DiscoveryModel *BluetoothDevice::deviceModel() const

Returns the model of the Bluetooth device.

Note: Getter function for property deviceModel.

bool BluetoothDevice::powered() const

Returns true if the power is switched on in the Bluetooth device.

Note: Getter function for property powered.

See also setPowered().

void BluetoothDevice::requestConnect(const QString &address)

Connects to the remote device specified by address.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

void BluetoothDevice::requestDisconnect(const QString &address)

Disconnects from the remote device specified by address.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

void BluetoothDevice::requestPairing(const QString &address)

Starts the process of pairing to a remote device specified by address, and connects to it if the pairing was successful.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

See also requestConnect.

bool BluetoothDevice::scanning() const

Returns whether the Bluetooth device is scanning for remote devices.

Note: Getter function for property scanning.

See also setScanning().

void BluetoothDevice::setPowered(const bool &aPowered)

Sets the powered state in the Bluetooth device to aPowered.

Note: Setter function for property powered.

See also powered().

void BluetoothDevice::setScanning(const bool &aScan)

Sets scanning in the Bluetooth device to aScan.

Note: Setter function for property scanning.

See also scanning().
