Serial Port Profile (SPP)
SPP defines how to set-up virtual serial ports and connect two Bluetooth enabled devices.

Service Layer Protocol
A protocol that uses an L2CAP channel for transporting PDUs.

Service Discovery
Procedures for querying and browsing for services offered by or through another Bluetooth enabled device.

Service Discovery Application Profile (SDAP)
SDAP describes how an application should use SDP to discover services on a remote device. SDAP requires that any application be able to find out what services are available on any Bluetooth enabled device it connects to.

Silent Device
A Bluetooth enabled device appears as silent to a remote device if it does not respond to inquiries made by the remote device.

SIM Access Profile (SAP)
SAP allows devices such as car phones with built in GSM transceivers to connect to a SIM card in a Bluetooth enabled phone. Therefore the car phone itself does not require a separate SIM card.

The SYNC profile is used in conjunction with GOEP to enable synchronization of calendar and address information (personal information manager (PIM) items) between Bluetooth enabled devices. A common application of this profile is the exchange of data between a PDA and computer.

Unknown device
A Bluetooth enabled device for which no information (Bluetooth device address, link key or other) is stored.

Video Distribution Profile (VDP)
VDP defines how a Bluetooth enabled device streams video over Bluetooth wireless technology. Sample use cases include the streaming of a stored video from a PC media centre to a portable player or streaming from a digital video camera to a TV.

WAP Over Bluetooth Profile (WAP)
WAP defines how the wireless application protocol suite can run over a Bluetooth wireless link. A typical configuration is a mobile phone connecting to a public kiosk over a Bluetooth wireless link and using WAP to browse for information. WAP works across a variety of WAN technologies bringing the Internet to mobile devices.
