According to section 1.2 of the Bluetooth 2.1+EDR and 4.0 Specifications, each Bluetooth device is allocated a unique 48-bit Bluetooth device address (BD_ADDR). This address consists of the following parts:

  • Lower address part (LAP), consisting of 24 bits
  • Upper address part (UAP), consisting of 8 bits
  • Non-significant address part (NAP), consisting of 16 bits

The LAP and UAP form the significant part of the BD_ADDR. Refer to Figure 1.5 in the Bluetooth 2.1+EDR Specifications for an example of a BD_ADDR.
