enabled Computation Engine to monitor the status of their health
with multiple Bluetooth enabled biosensors.

26. PERSONAL AREA NETWORKING
PROFILE [PAN]
 PAN describes how two or more
Bluetooth enabled devices can form
an ad-hoc network and how the
same mechanism can be used to
access a remote network through a
network access point.
 Usage Scenarios

(or laptops) connecting wirelessly to one
"master" PC, or Network Access Point.
This will also allow for remote access of
the "master" PC.

27. 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.

28. SIM ACCESS PROFILE [SAP]
 This allows devices such as car phones with built in GSM
transceivers to connect to a SIM card in a phone with
Bluetooth, so the car phone itself doesn't require a
separate SIM card.

29. SYNCHRONIZATION PROFILE

 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.

entries stored in the Phone Book Server Equipment (PSE).
 The PCE to down load one or several phone book entries from the PSE.
 The PCE to access the call histories stored in the PSE.
 The PCE to access the Subscriber number information stored in the PSE.

33. OBJECT PUSH PROFILE [OPP]
 OPP defines the roles of push server and push client.These roles
are analogous to and must interoperate with the server and
client device roles that GOEP defines.
 Usage Scenarios
 An example scenario would be the exchange of a contact or
appointment between two mobile phones, or a mobile phone and a
PC.

34. ALERT NOTIFICATION PROFILE
[ANP]
 The Alert Notification Profile (ANP) enables a client device to
receive different types of alerts and event information, as well as
information on the count of new alerts and unread items, which
exist in the server device.
 Usage Scenarios
 The Alert Notification profile allows a device like a watch to obtain
information from a cell phone about incoming calls, missed calls and
SMS/MMS messages.The information may include the caller ID for
an incoming call or the sender's ID for email/SMS/MMS but not the
message.This profile also enables the client device to get
information about the number of unread messages on the server
device.

 The Blood Pressure Profile (BLP) enables a device to connect
and interact with a Blood Pressure Sensor device for use in
consumer and professional health care applications.
 Usage Scenarios
 The Blood Pressure Profile is used to enable a device to obtain blood
pressure measurement and other data from a non-invasive blood
pressure sensor that exposes the Blood Pressure Service. For
example, a nurse or doctor could use a non-invasive blood pressure
sensor on a patient that sends blood pressure measurements to a
laptop or other hand held device.

36. FIND ME PROFILE [FMP]
 The Find Me profile (FMP) defines the behavior when a button is
pressed on one device to cause an alerting signal on a peer
device.

misplaced.

37. HEALTHTHERMOMETER PROFILE
(HTP)
 The HealthThermometer Profile (HTP) enables a Collector
device to connect and interact with aThermometer sensor for
use in healthcare applications.
 Usage Scenarios
 The HealthThermometer Profile allows temperature information to
be sent from a thermometer sensor to another device, such as at a
doctor's office. A nurse or doctor could take a patient's temperature
using a thermometer and have that information automatically
uploaded to the patients file.

38. HEART RATE PROFILE (HRP)
 The Heart Rate Profile (HRP) enables a Collector device to
connect and interact with a Heart Rate Sensor for use in fitness
applications.
 Usage Scenarios
 The Heart Rate Profile allows heart rate information to be sent from
one sensor (heart rate monitor) to another device, such as at a
doctor's office. A nurse or doctor could take a patient's heart rater
and have that information automatically uploaded to the patients
file.

39. PROXIMITY PROFILE [PXP]
 The Proximity profile (PXP) enables proximity monitoring
between two devices.
 Usage Scenarios
The Proximity profile defines the behavior when a device moves away
from a paired device so that the connection is dropped or the path loss
increases above a preset level, causing an immediate alert.This alert can
be used to notify the user that the devices have become separated. As a
consequence of this alert, a device may take further action, for example
to lock one of the devices so that it is no longer usable.
