2 by an interface point that
has nothing connected to it.
Figure 2.2 shows that in addition to providing access to the
functionality of Bluetooth protocols, JABWT provides access to
the functionality specified by the Bluetooth profiles. The star shapes
in Figure 2.2 represent Bluetooth profiles. JABWT applications
have access to selected functionality from the following Bluetooth
profiles:
??? GAP
??? SDAP
??? SPP
??? GOEP
In functional terms, JABWT provides the following Bluetooth
capabilities:
??? Registering services
??? Discovering devices and services
??? Establishing RFCOMM, L2CAP, and OBEX connections
??? Conducting the above three activities in a secure manner
The following capabilities were considered to be outside the scope of
JABWT. However, there is no incompatibility between JABWT and these
functions, so JABWT applications may have access to these functions on
some devices:
??? Layer management: Many aspects of layer management are system
specific and are difficult to standardize, such as power modes and
park mode.
??? Downloading and storing applications: These features are implementation
specific and therefore are not defined in JABWT. Overthe-
air provisioning is being addressed in other JSRs.
