|
| Constant | Value | Description |
|---|---|---|
| QBluetoothLocalDevice::NoError | 0 | No known error |
| QBluetoothLocalDevice::PairingError | 1 | Error in pairing |
| QBluetoothLocalDevice::UnknownError | 100 | Unknown error |
enum QBluetoothLocalDevice::HostMode
This enum describes the most of the local Bluetooth device.
| Constant | Value | Description |
|---|---|---|
| QBluetoothLocalDevice::HostPoweredOff | 0 | Power off the device |
| QBluetoothLocalDevice::HostConnectable | 1 | Remote Bluetooth devices can connect to the local Bluetooth device if they have previously been paired with it or otherwise know its address. This powers up the device if it was powered off. |
| QBluetoothLocalDevice::HostDiscoverable | 2 | Remote Bluetooth devices can discover the presence of the local Bluetooth device. The device will also be connectable, and powered on. |
| QBluetoothLocalDevice::HostDiscoverableLimitedInquiry | 3 | Remote Bluetooth devices can discover the presence of the local Bluetooth device when performing a limited inquiry. This should be used for locating services that are only made discoverable for a limited period of time. This can speed up discovery between gaming devices, as service discovery can be skipped on devices not in LimitedInquiry mode. In this mode, the device will be connectable and powered on, if required. |
enum QBluetoothLocalDevice::Pairing
This enum describes the pairing state between the two Bluetooth devices.
| Constant | Value | Description |
|---|---|---|
| QBluetoothLocalDevice::Unpaired | 0 | The Bluetooth devices are not paired. |
| QBluetoothLocalDevice::Paired | 1 | The Bluetooth devices are paired. The system will prompt the user for authorization when the remote device initiates a connection to the local device. |
| QBluetoothLocalDevice::AuthorizedPaired | 2 | The Bluetooth devices are paired. The system will not prompt the user for authorization when the remote device initiates a connection to the local device. |
Member Function Documentation
QBluetoothLocalDevice::QBluetoothLocalDevice(QObject * parent = 0)
Constructs a QBluetoothLocalDevice with parent.
QBluetoothLocalDevice::QBluetoothLocalDevice(const QBluetoothAddress & address, QObject * parent = 0)
Construct new QBluetoothLocalDevice for address.
QBluetoothLocalDevice::~QBluetoothLocalDevice() [virtual]
Destroys the QBluetoothLocalDevice.
QBluetoothAddress QBluetoothLocalDevice::address() const
Returns the MAC address of this Bluetooth device.
QList<QBluetoothHostInfo> QBluetoothLocalDevice::allDevices() [static]
Returns a list of all available local Bluetooth devices.
void QBluetoothLocalDevice::error(QBluetoothLocalDevice::Error error) [signal]
Signal emitted if there's an exceptional error while pairing.
HostMode QBluetoothLocalDevice::hostMode() const
Returns the current host mode of this local Bluetooth device.
See also setHostMode().
void QBluetoothLocalDevice::hostModeStateChanged(QBluetoothLocalDevice::HostMode state) [signal]
The state of the host has transitioned to a different HostMode.
bool QBluetoothLocalDevice::isValid() const
Returns true if the QBluetoothLocalDevice represents an available local Bluetooth device; otherwise return false.
QString QBluetoothLocalDevice::name() const
Returns the name assgined by the user to this Bluetooth device.
void QBluetoothLocalDevice::pairingConfirmation(bool accept) [slot]
To be called after getting a pairingDisplayConfirmation(). The accept parameter either accepts the pairing or rejects it.
void QBluetoothLocalDevice::pairingDisplayConfirmation(const QBluetoothAddress & address, QString pin) [signal]
Signal by some platforms to display a pairing confirmation dialog for address. The user is asked to confirm the pin is the same on both devices. QBluetoothLocalDevice::pairingConfirmation(bool) must be called to indicate if the user accepts or rejects the displayed pin.
void QBluetoothLocalDevice::pairingDisplayPinCode(const QBluetoothAddress & address, QString pin) [signal]
Signal by some platforms to display the pin to the user for address. The pin is automatically generated, and does not need to be confirmed.
void QBluetoothLocalDevice::pairingFinished(const QBluetoothAddress & address, QBluetoothLocalDevice::Pairing pairing) [signal]
Pairing has completed with address. Current pairing status is in pairing.
Pairing QBluetoothLocalDevice::pairingStatus(const QBluetoothAddress & address) const
Returns the current bluetooth pairing status of address, if it's unpaired, paired, or paired and authorized.
void QBluetoothLocalDevice::powerOn()
Powers on the device after returning it to the hostMode() state, if it was powered off.
void QBluetoothLocalDevice::requestPairing(const QBluetoothAddress & address, Pairing pairing)
Set the pairing status with address. The results are returned by the signal, pairingFinished(). Caution: creating a pairing may take minutes, and may require the user to acknowledge.
void QBluetoothLocalDevice::setHostMode(QBluetoothLocalDevice::HostMode mode)
Sets the host mode of this local Bluetooth device to mode.
