o Dial-up Networking Profile.
o LAN Access Profile.
o Synchronization Profile.
The Service discovery application profile, describes the features and.
procedures used to discover services registered on other Bluetooth wireless.
devices using the Bluetooth Service Discovery Protocol (SDP). The SDP uses only connection-oriented channels, however the SDP itself is a connectionless datagram service and it depends on the L2CAP layer to create and manage connections. .
SDP is the initial connection and pairing of devices and it does not.
require the use of authentication or encryption for SDP transactions. If.
authentication is performed on the Bluetooth wireless devices to be involved in.
an SDP procedure, then the devices must pass the authentication test to.
perform SDP procedures. Therefore any security procedures applied to the.
SDP are determined by those used to negotiate the connections between the.
specific Bluetooth wireless devices. .
Since SDP security is based on device access to the SDP service, security.
may be provided by restricting access to trusted devices. Most probably the trust relationship is arranged in advance using the Bluetooth pairing mechanism. Once the devices have been paired, SDP is available and no.
additional security procedures are implemented.
In the case of a connection between un-trusted or unknown devices, the.
service record is freely available, since no security is applied, where SDP only provides a record indicating what services are available. .

The "Headset Profile" depends on both the "Serial Port Profile "and the "Generic Access Profile". The "Serial Port Profile" provides RS-232 serial cable emulation for Bluetooth wireless devices. The "Generic Access Profile" (GAP) describes several security aspects of Bluetooth wireless connections. Since the Headset Profile inherits characteristics from the GAP, these aspects also apply to the "Headset Profile.".
A typical headset configuration consists of two devices, a Headset (HS) and.
