For more detailed descriptions on how to configure the server and client, please refer to the detailed description sections in the QBluetoothServer and QBluetoothSocket classes.īluetooth Low Energy, also known as Bluetooth Smart, is a new technology enabling devices with low energy consumption to communicate with each other. It is perfectly suited for gaming or for syncing the state between two instances of an application on two devices. Using such a connection allows to exchange any form of data in both directions. The more flexible approach for communication between two Bluetooth enabled devices, is to create a virtual serial port connection and freely exchange data over that connection.Ĭonnect to this server from another device playing the client role by using a QBluetoothSocket. To push files to remote devices, create a QBluetoothTransferRequest and ask the QBluetoothTransferManager to push the file contained in the request by calling its put function. The profile does not require the two devices to be paired before exchanging data. As the name describes, this profile can push files from one device to another.Ĭurrently it is not possible to pull files or browse the remote file system. Once the desired device was found, there are two main use cases provided by Qt Bluetooth.
Although you can just create QBluetoothDeviceInfo objects on your own and fill them with data, the easier way is to use the QBluetoothDeviceDiscoveryAgent to start an automated search for visible Bluetooth devices within the connectable range. QBluetoothLocalDevice is the class that provides all of this information. The first steps in retrieving device information are to check if Bluetooth is available on the device and read the local device address and name. The first one is to obtain local and remote device information. Also, it is only possible to find devices that have been previously paired through Windows Settings. Therefore, registering a service with custom values for these fields might not yield the expected result on Windows.
