如何从蓝牙端口读取串行数据？ C ++

Question

我创建了一个程序，使用C ++从COM端口读取串行数据，但是由于我的项目发生了变化，我必须从BT端口读取数据。由于我使用蓝牙适配器将我的计算机连接到设备，我预计阅读过程是相同的，但显然不是。由于我使用Window OS来执行此任务，GetLastError（）返回2，这意味着找不到指定的文件。但是，当我使用Arduino的串行监视器时，数据读得很好。有谁知道如何从C ++的BT端口读取？我顺便使用Windows 8，这是我的代码：

#include "stdafx.h"
int _tmain(int argc, _TCHAR* argv[])
{
///-----------------------------Open port-----------------------------------------------------------------

// Name of port where device is found
LPCWSTR port = L"COM40";

// Open port for reading
HANDLE hComm = ::CreateFile(port, GENERIC_READ | GENERIC_WRITE, 0, 0, OPEN_EXISTING, 0, 0);

// Check if port has been opened succesfully
if (hComm == INVALID_HANDLE_VALUE) std::cout << "Failed to open " << port << " error: " << GetLastError() << std::endl;
else std::cout << port << " has been opened succesfully\n";

///-----------------------------Configure port------------------------------------------------------------

// Create DCB structure 
DCB dcb = { 0 };

// Get Comm state
if (!::GetCommState(hComm, &dcb)) std::cout << "Failed to get Comm state, error: " << GetLastError() << std::endl;

// Configure strcutre
dcb.DCBlength = sizeof(DCB);

// Set Baud rate
dcb.BaudRate = CBR_9600;
// Set number of bytes in bits that are recieved through the port
dcb.ByteSize = 8;
dcb.StopBits = ONESTOPBIT;

// Check if port has been configured correctly
if (!::SetCommState(hComm, &dcb)) std::cout << "\nFailed to set Comm State, error: " << GetLastError();
else std::cout << "Comm state has been set succesfully\n";

///-----------------------------Read data-------------------------------------------------------------------

char buffer;
DWORD maxBytes = 1;
if (!::ReadFile(hComm, &buffer, maxBytes, NULL, NULL)) std::cout << "\nFailed to read from " << port << " error: " << GetLastError() << std::endl;
else std::cout << "File has been read succesfully\n";

///-----------------------------Write to text file----------------------------------------------------------

std::fstream file;
int counter = 0;
// Writing to text file will be done later
while (ReadFile(hComm, &buffer, maxBytes, NULL, NULL))
{
    std::cout << buffer;
}

///-----------------------------Close port------------------------------------------------------------------

CloseHandle(hComm);
file.close();

std::cout << "\nCOM40 has been closed!\n";
return 0; 
}
