Qt Bluetooth Module

The Qt Bluetooth module offers a Bluetooth API and common Bluetooth profile implementations. It is based on the Base module.

The following configure line can be used to build the Base and Bluetooth module only:

    ./configure -modules bluetooth -device xyz

Note that not specifying a device profile would result in the reference device being build. The -bluetooth option is equivalent to the -modules cell option.

Feature description

The Qt Extended Bluetooth support is based on Bluez. The provided Bluetooth API's function as a wrapper around Bluez and allow direct manipulation of Bluetooth devices. In addition the Bluetooth Service Management Framework can be used to create arbitrary Bluetooth service. Most profile implementations are based on this framework and the more generic classes mentioned earlier.

FeatureDetails
Device and service ControlThe device and service control classes provide the most basic set of classes for arbitrary Bluetooth development:
Bluetooth profilesThis module supports a variety of Bluetooth profiles. Please check the Bluetooth documentation for the list of supported profiles.
General file transfer user interfaceA server task monitors transfer operations and shows a status widget while the transfer is in progress. This feature is shared with various Infrared transfer protocols.

Software components

The Bluetooth module includes the following software components:

  • libraries/qtopiaaudio
  • libraries/qtopiapim
  • bluetooth settings and bluetooth FTP applications
  • libraries/qtopiacomm (bluetooth components)
  • profile related server components

The exact list of components included in this module can be found in $QPEDIR/src/module_bluetooth.pri.

The test plan for the Bluetooth module summarizes the Quality Assurance procedures for this module. The results of these test are available here.

The following table contains all classes and services which are part of this module:
