Table 7.6 Bluetooth profiles for different applications.

Profile name Application

Headset profile Profile for wireless headsets used with mobile phones. Voice quality
transmissions only, not suitable for music
Hands‐free profile This profile is used to connect mobile phones with hands‐free sets in
cars
SIM access profile Provides access for hands‐free equipment in cars to the data stored on
the SIM card of a mobile phone
Human interface device Connects mouses, keyboards and joysticks to PCs, notebooks and
(HID) profile smartphones
File transfer profile This profile can be used to exchange files between two Bluetooth
devices
Object push profile Simple exchange of calendar entries, address book entries, etc.; used
for ad hoc transfers
Advanced audio Profile for the transmission of high‐quality audio, for example, music
distribution profile between an MP‐3 player and a Bluetooth headset
Audio/video remote Profile to control audio/video devices remotely. This profile can be
control profile used, for example, with the advanced audio distribution profile to
remotely control the audio player from the headset or an independent
remote control
Dial‐up networking (DUN) Bluetooth connection between a modem or a mobile phone and a
profile remote device like a PC or a notebook
FAX profile Profile for FAX transmissions
Common ISDN access Profile for interconnecting an ISDN adapter with a remote device like
profile a PC or notebook
LAN access profile IP connection between a smartphone, PC or notebook and a LAN and
the Internet
Personal area network Same as the LAN access profile. However, the PAN profile does not
(PAN) profile simulate an Ethernet network card but instead uses Bluetooth
protocols for this purpose
Synchronization profile Synchronization of personal information manager (PIM) applications
for calendar and address book entries, notes, etc.
Basic imaging profile Transfer of pictures from and to digital cameras
Hard copy cable Cable replacement between printers and a remote device like a PC
replacement profile
Basic printing profile Printing profile for mobile devices like mobile phones to enable them
to print information without a printer driver

application. The profile uses the RFCOMM layer, which already offers all necessary
functionalities on a lower layer. If a device has implemented this profile, any higher‐
layer application that is able to transfer data over a serial interface is able to communi-
cate with remote Bluetooth devices. A special adaptation of the application to the
Bluetooth protocol stack is not necessary because on the application layer the simulated
Bluetooth serial interface behaves like a physically present serial interface. Figure 7.18
shows the protocol stack of the SPP.
