The Bluetooth device address stores the network address of a Bluetooth–enabled device. It is used to identify a particular device during operations such as connecting to, pairing with, or activating the device.
A Bluetooth–enabled device address is a unique, 48–bit address containing the following three fields:
- LAP field: lower part of the address containing 24 bits.
- UAP field: upper part of the address containing 8 bits.
- NAP field: non–significant part of the address containing 16 bits.
The LAP and the UAP represent the significant address part (SAP) of the Bluetooth device address.
About BT_ADDR
The Bluetooth device address is represented as BT_ADDR, defined in ws2bth.h:
typedef ULONGLONG bt_addr, *pbt_addr, BT_ADDR, *PBT_ADDR;
You can use the following macros defined in ws2bth.h to translate between BT_ADDR and NAP or SAP:
#define GET_NAP(_bt_addr)
#define GET_SAP(_bt_addr)
