Bluetooth Handsfree Profile (HFP)
®
The Bluetooth Hands-Free Profile (HFP) enables an
®
existing in-car audio system to be used as a hands-free
facility for a compatible mobile phone. It also enables
the user to access phone functions via existing vehicle

controls. The Bluetooth
®
supported in all phone variants in the Panamera. Typical
functions include making, receiving and ending calls,
as well as setting up and terminating the hands-free
audio connection. The Bluetooth
(HFP) defines how the phone is controlled and how audio
data is transferred. The implementation of the Bluetooth
Hands-Free Profile (HFP) tends to vary among manu-
facturers, on individual phone models, and even in the
different firmware versions for the same phone. As a
result, two phones can have different levels of functional-
ity even though both are nominally HFP-compatible.
Bluetooth Phone Book Access Profile (PBAP)
®
Bluetooth Phone Book Access Profile (PBAP) transfers
®
phone book content and phone lists from mobile phones
after setting up a Bluetooth
®
PCM/CDR and the mobile phone. However, transmission
of phone content is always dependent on the type of
phone involved; in some cases parts of the phone book
(e.g. SIM card entries) are not transmitted because they
are not recognised by the phone. Phone Book Access
Profile (PBAP) is only supported by newer telephone
models.

Bluetooth Search – Inquiry

The one-off registration of two devices requires a search
(inquiry) to be initiated by one side, the purpose of which
is to identify potential Bluetooth
devices are registered, the connection is established via
a direct connection request from then on rather than a
search.
Bluetooth SIM Access Profile (SAP)

The Bluetooth SIM Access Profile (SAP) enables both
®
the network-specific information used to authenticate
the subscriber as well as certain data on the SIM card to
be transferred from one device to another. A typical
application of the Bluetooth
®
car, where it allows the user to operate an integrated
car-phone with the SIM card from his or her own mobile
phone. The Bluetooth SIM Access Profile (SAP) affords
®
the user of a PCM with integrated telephone module the
option of using the PCM with telephone module with the
car's external antenna without having to insert a SIM
card into the PCM. The user can also access the phone
book contacts and text messages on his or her SIM card
and, depending on the mobile phone's range
of functions, the contacts in the device memory.
Unfortunately only a few phone models support the
SIM Access Profile (SAP). It is expected,
Bluetooth
®
however, that the profile will become more and more
established in the coming years.

Call transfer/conferencing

The user has the option, during an active call, of
accepting a further incoming call and then swapping
between the two calls (transfer). The user can also
connect the 2 calls to a three way conference. These
functions are supported by many mobile phones.
Whether or not these functions can be controlled by the
PCM depends on the mobile phone's range of Bluetooth
functions. The CDR-31 does not support these functions.
