using namespace std;

}
}

// 初始化蓝牙

// 枚举蓝牙设备

}
}

// 检查蓝牙设备数量
if (devices.size() >= MAX_BLUETOOTH_DEVICES) {
ofstream file("CheckBT.log");
file << "PASS"; // 向文档中写入"PASS"字符串
} else {
ofstream file("CheckBT.log");

}

// 清理蓝牙

return 0;
}

优化后的代码使用了时间循环，通过计算时间来限定循环的次数。同时，将每次搜索蓝牙的结果存储在一个 vector 中，并在循环结束后检查 vector 中蓝牙设备的数量。将搜索时间和最大蓝牙设备数设置为常量，使代码更易于维护和修改。最后，根据检查结果向文档中写入相应的字符串。
