MinBitpool
DWORD
The minimum bit pool value supported. This value must be between 2 and
25. The default value is used when data is outside the range of 2 to 250,
or if MaxBitpool is smaller than MinBitpool. The default value is 18.
MaxBitpool
DWORD
The maximum bit pool value supported. The default value is used when
data is outside the range of 2 to 250, or if MaxBitpool is smaller than
MinBitpool. The default value is 53.
44KHz
DWORD
The preference for a 44.1 KHz sample rate over a 48 KHz sample rate. A
value of 0 indicates 48 KHz, whereas a value of 1 indicates 44.1 KHz. The

HKEY_LOCAL_MACHINE\Software\Microsoft\BTPairSvc\Profiles
The Bluetooth Pairing Service uses this registry key to maintain information about profiles and paired devices. The
BTAV service adds subkeys to the Profiles key for A2DP, audio source, and AVRCP profiles, and examines the Devices
key for profile information about paired devices. The BTAV service will not use devices that do not support the
required profiles.

Calendar
Windows Embedded Automotive 7 can download calendar information from mobile devices.
Devices that use standard Bluetooth protocols, such as OBEX, SyncML, and Sync Profile, support
import functionality for calendar and task information. Calendar storage is based on the
Bluetooth address of the device and is stored in POOM storage. Automotive 7 supports virtual
calendar (vCalendar) 1.0 and iCalendar 2.0, as well as vCalendar send.
Automotive 7 uses the CalNot.exe application for setting and deleting existing POOM
notifications. An application can turn notifications on and off for the currently connected phone.
