Internal Representation for Bluetooth Address (Windows CE 5.0)

The BD_ADDR structure is used by all stack interfaces.

#pragma pack(push, 1)
typedef struct   __bd_addr {
   union {
      struct {
         unsigned int LAP : 24;   // Lower address part
         unsigned int UAP : 8;   // Upper address part
      };
      unsigned int SAP;         // Significant address part
   };

   unsigned short NAP;            // Non-significant address part
} BD_ADDR;
#pragma pack(pop)

**Note   **Exposed user APIs, such as port emulation and Winsock interfaces, use another type called BT_ADDR, defined in ws2bth.h.

typedef ULONGLONG bt_addr, *pbt_addr, BT_ADDR, *PBT_ADDR;

The following code example shows how to convert the BT_ADDR type to BD_ADDR.

BD_ADDR bda = (BD_ADDR*)pbt;

Conversely, you can use the SET_NAP_SAP macro to convert a Bluetooth address stored in BD_ADDR to the BT_ADDR type. The following code example shows how to use SET_NAP_SAP.

BT_ADDR bta = SET_NAP_SAP(bda.NAP, bda.SAP);
