Figure 1 BlueZ Bluetooth Protocol Stack Architecture
2.2.3 Application
iNavi Android BlueZ Stack is most likely to be used for navigation system.
2.2.4 Block Diagram
iNavi Android BlueZ Stack is made of GAP(Generic Access Profile), L2CAP(Logical Link Control
and Adaptation Protocol), SDP(Service Discovery Protocol), and BNEP(Bluetooth Network
Encapsulation Protocol).
L2CAP layer exist in Linux Kernel, and GAP and BNEP are located in both Linux Kernel and
BlueZ 4.7. and SDP is placed in BlueZ 4.7 only.
iNavi Android BlueZ Stack uses the D-Bus interface for communicating with other applications
and modules. The BlueZ D-Bus architecture is shown in Figure 2.
The BlueZ D-Bus services are exported through the system message bus. Every D-Bus enabled
device has a system message bus instance running. This bus is used to broadcast system events,
such as new hardware devices, network connection status, and so forth. The session message
