基于Windows的蓝牙音乐开发 C++

要基于Windows的蓝牙音乐开发C++，可以使用Windows Bluetooth API来实现。以下是一些步骤：

1. 在Visual Studio中创建一个新的Win32控制台应用程序。

2. 在代码中包含Windows Bluetooth API头文件bluetoothapis.h和Winsock API头文件winsock2.h。

3. 初始化Winsock API，使用以下代码：

WSADATA wsaData;
int iResult = WSAStartup(MAKEWORD(2, 2), &wsaData);
if (iResult != 0) {
    printf("WSAStartup failed: %d\n", iResult);
    return 1;
}

4. 初始化Bluetooth API，使用以下代码：

BLUETOOTH_FIND_RADIO_PARAMS btParams = { sizeof(BLUETOOTH_FIND_RADIO_PARAMS) };
HANDLE hRadio = NULL;
HBLUETOOTH_RADIO_FIND hFind = BluetoothFindFirstRadio(&btParams, &hRadio);
if (hFind == NULL) {
    printf("BluetoothFindFirstRadio failed\n");
    WSACleanup();
    return 1;
}

5. 枚举附近的蓝牙设备，使用以下代码：

BLUETOOTH_DEVICE_SEARCH_PARAMS btSearchParams = { sizeof(BLUETOOTH_DEVICE_SEARCH_PARAMS) };
btSearchParams.fReturnAuthenticated = TRUE;
btSearchParams.fReturnRemembered = TRUE;
btSearchParams.fReturnConnected = TRUE;
btSearchParams.fIssueInquiry = TRUE;
btSearchParams.cTimeoutMultiplier = 2;

HBLUETOOTH_DEVICE_FIND hFind;
BLUETOOTH_DEVICE_INFO btDeviceInfo = { sizeof(BLUETOOTH_DEVICE_INFO) };
hFind = BluetoothFindFirstDevice(&btSearchParams, &btDeviceInfo);
if (hFind == NULL) {
    printf("BluetoothFindFirstDevice failed\n");
    BluetoothFindRadioClose(hRadio);
    WSACleanup();
    return 1;
}

do {
    printf("Device Name: %s\n", btDeviceInfo.szName);
    printf("Device Address: %02X:%02X:%02X:%02X:%02X:%02X\n",
        btDeviceInfo.Address.rgBytes[5],
        btDeviceInfo.Address.rgBytes[4],
        btDeviceInfo.Address.rgBytes[3],
        btDeviceInfo.Address.rgBytes[2],
        btDeviceInfo.Address.rgBytes[1],
        btDeviceInfo.Address.rgBytes[0]);
} while (BluetoothFindNextDevice(hFind, &btDeviceInfo));

BluetoothFindDeviceClose(hFind);

6. 连接到蓝牙设备，使用以下代码：

SOCKADDR_BTH sa;
sa.addressFamily = AF_BTH;
sa.btAddr = btDeviceInfo.Address;
sa.serviceClassId = RFCOMM_PROTOCOL_UUID;
sa.port = 1;

SOCKET s = socket(AF_BTH, SOCK_STREAM, BTHPROTO_RFCOMM);
if (s == INVALID_SOCKET) {
    printf("socket failed: %ld\n", WSAGetLastError());
    BluetoothFindRadioClose(hRadio);
    WSACleanup();
    return 1;
}

int iResult = connect(s, (SOCKADDR *)&sa, sizeof(sa));
if (iResult == SOCKET_ERROR) {
    printf("connect failed: %ld\n", WSAGetLastError());
    closesocket(s);
    BluetoothFindRadioClose(hRadio);
    WSACleanup();
    return 1;
}

7. 发送音乐数据，使用以下代码：

char musicData[1024];
int bytesSent = send(s, musicData, sizeof(musicData), 0);
if (bytesSent == SOCKET_ERROR) {
    printf("send failed: %ld\n", WSAGetLastError());
    closesocket(s);
    BluetoothFindRadioClose(hRadio);
    WSACleanup();
    return 1;
}

8. 关闭连接和清理资源，使用以下代码：

closesocket(s);
BluetoothFindRadioClose(hRadio);
WSACleanup();

以上是基于Windows的蓝牙音乐开发C++的一些步骤，具体实现还需要根据实际情况进行调整。
