问题：
- 我要寻找一些code例子，说明我如何才能找到连接到我的电脑的蓝牙设备。
- 我要寻找一些code例子，说明我如何从我的电脑传输信息到移动设备上。
- I am looking for some code examples which show how can I find Bluetooth devices that are connected to my computer.
- I am looking for some code examples which show how can I transfer information from my computer to a mobile device.
现在我试图制定关于C ++应用程序必须与 蓝牙 <工作/ A>设备。虽然我是通过互联网研究，我发现有关蓝牙的一些信息，我发现了一些code例子女巫present如何与蓝牙设备配合使用。例如 这里 我发现code女巫presents如何利用内的所有蓝牙无线电的范围内找到所有的蓝牙设备：
Now I am trying to develop application on C++ which must work with Bluetooth devices. While I was researching through internet I found some information about Bluetooth and I found some code examples witch present how can work with Bluetooth devices. For example here I found code witch presents how can use find all bluetooth devices within range of all bluetooth radios:
#define WIN32_LEAN_AND_MEAN

#include <stdlib.h>
#include <winsock2.h>
#include <bthdef.h>

};
// The BLUETOOTH_DEVICE_INFO structure provides information

BLUETOOTH_DEVICE_INFO m_device_info = {

};
HANDLE m_radio = NULL;
HBLUETOOTH_RADIO_FIND m_bt = NULL;
HBLUETOOTH_DEVICE_FIND m_bt_dev = NULL;
int wmain(int argc, wchar_t **args) {
while(true) {
// The BluetoothFindFirstRadio function begins the

m_bt = BluetoothFindFirstRadio(&m_bt_find_radio, &m_radio);
int m_radio_id = 0;
do {
m_radio_id++;
// The BluetoothGetRadioInfo function obtains information

BluetoothGetRadioInfo(m_radio, &m_bt_info);
wprintf(L"Radio %d:\r\n", m_radio_id);
wprintf(L"\tName: %s\r\n", m_bt_info.szName);

m_device_info.dwSize = sizeof(BLUETOOTH_DEVICE_INFO);
m_bt_dev = BluetoothFindFirstDevice(&m_search_params, &m_device_info);
int m_device_id = 0;
do {
m_device_id++;
wprintf(L"\tDevice %d:\r\n", m_device_id);

} while(BluetoothFindNextDevice(m_bt_dev, &m_device_info));
BluetoothFindDeviceClose(m_bt_dev);
} while(BluetoothFindNextRadio(&m_bt_find_radio, &m_radio));
BluetoothFindRadioClose(m_bt);
Sleep(10000);
}
return 0;
}
然后，我创建项目，并在我的笔记本上运行它开启蓝牙没有结果出现。至于如果应用程序找不到任何蓝牙设备。之后我继续我的研究，发现其他物品 查找Bluetooth设备和服务使用名为C ++在Windows XP

当我编译出现这一个，启动应用程序错误消息在初始化查找设备上发生的错误，收盘...... ！
When I compile this one and launch application error message appears"An error occurred while initializing look for devices, closing ......" !!!
如果您可以给我发信息的任何物品，code例子或别的东西与帮助我在我的研究，我将非常高兴，感谢你！
顺祝商祺！
