Each Bluetooth device shall be allocated a unique 48-bit Bluetooth device
address (BD_ADDR). This address shall be obtained from the IEEE
Registration Authority. The address shall be created in accordance with section
9.2 ("48-bit universal LAN MAC addresses") of the IEEE802-2001 standard
(http://standards.ieee/findstds/standard/802-2001.html)and using a valid
Organizationally Unique Identifier (OUI) obtained fromthe IEEE Registration
Authority (see http://standards.ieee/regauth/oui/forms/and sections 9 and
9.1 of the IEEE 802-2001 specification). The LAP and UAP form the significant
part of the BD_ADDR.The bit pattern in Figure 1.5is an example BD_ADDR.
The BD_ADDR may take any values except the 64 reserved LAP values for
general and dedicated inquiries (see Section 1.2.1 on page 69).
1.2.1 Reserved Addresses
A block of 64 contiguous LAPs is reserved for inquiry operations; one LAP
common to all devices is reserved for general inquiry, the remaining 63 LAPs
are reserved for dedicated inquiry of specific classes of devices (see Assigned
Numbers). The same LAP values are used regardless of the contents of UAP
and NAP. Consequently, none ofthese LAPs can be partof a user BD_ADDR.
The reserved LAP addresses are 0x9E8B00-0x9E8B3F. The general inquiry
LAP is 0x9E8B33. All addresses have the LSB at the rightmost position,
hexadecimal notation. The default check initialization (DCI) is used as the UAP
whenever one of the reserved LAP addresses is used.The DCI is defined to be
0x00 (hexadecimal).
