Getting external callbacks (SDK) called in a ROS node

edit

Hello all;

I am trying to integrate a new sensor in a robot. This sensor provides an SDK and the way of acquiring its data is by using a callback, everytime that there are data available, the callback is called. Inside the callback it is possible to access the data. The program with the SDK has been tested and works fine, accesing the sensor callback. The problem comes when trying to integrate all thi code in ROS. ROS is attending to its framework and callbacks, and the sensor callback is not being executed. Due to the characteristics of the SDK of the sensor, I can not call the callback explicitly when I want to collect data. The library is a Windows SDK, there is not a Linux Version, so, we are using WinROS with this node...

Is there any way to make ROS attend callbacks that are not from its own environment??

UPDATE. CODE ATTACHED

#include<smart_ray/smart_ray.h>

void smartRayControlCb(const std_msgs::BoolConstPtr &msg)
{

    if(msg->data)
    {
        initSmartRaySensor();
        //captura
        startSmartRayCapture();
    }
    else
    {
        stopSmartRaySensor();
    }

}
