wince 蓝牙 操作 搜索蓝牙设备 建立连接 建立虚拟串口 MFC

我弄的时候 也看了下网络资料 多少有些缺陷 现在我把我整理好的 贴出来

一共 分为 3部分 bluetooth.H bluetooth.cpp 使用说明 这几部分

1.bluetooth.h

#ifndef BLUETOOTH_H

#define BLUETOOTH_H

#include "winsock2.h"

#include "Ws2bth.h"

typedef struct BluetoothInfo

{

BT_ADDR Addr;

TCHAR Name[32];

int ComNum;

}BTINFO;

//搜索蓝牙设备存放到 btinfo数组中

bool BluetoothSearch(BTINFO btinfo[16],int *DeviceNum);

//根据蓝牙地址 创建 虚拟串口 并返回窗口号

int BluetoothCOMCreate (BT_ADDR ServerAddress);

//销毁 所创建的 蓝牙虚拟串口

void BluetoothCOMDestroy(void);

#endif

2.buletooth.cpp

3.使用说明

int DeviceNum = 0;

BTINFO BtInfoArry[16];

BluetoothSearch(BtInfoArry,&DeviceNum);
