Building PollingSample doesn't work

[sashaVR]

Hi everyone,

I'm new to Leap Motion development and I'm having an issue when I try PollingSample.c.

By looking at the Control Panel, The Leap Motion seems to work pretty fine ( every status is GOOD/GREEN ).

But when I debug the application, it blocks at the while(!IsConnected) and never passed this condition to continue the program.

I'm using Leap Motion SDK 4.0.0+52173.

int main(int argc, char** argv) {
  OpenConnection();
  while(!IsConnected)
    millisleep(100); //wait a bit to let the connection complete

  printf("Connected.");
  LEAP_DEVICE_INFO* deviceProps = GetDeviceProperties();
  if(deviceProps)
    printf("Using device %s.\n", deviceProps->serial);

  for(;;)
  {
    LEAP_TRACKING_EVENT *frame = GetFrame();
    if(frame && (frame->tracking_frame_id > lastFrameID))
    {
      lastFrameID = frame->tracking_frame_id;
      printf("Frame %lli with %i hands.\n", (long long int)frame->tracking_frame_id, frame->nHands);
      for(uint32_t h = 0; h < frame->nHands; h++)
      {
        LEAP_HAND* hand = &frame->pHands[h];
        printf("    Hand id %i is a %s hand with position (%f, %f, %f).\n",
                    hand->id,
                    (hand->type == eLeapHandType_Left ? "left" : "right"),
                    hand->palm.position.x,
                    hand->palm.position.y,
                    hand->palm.position.z);
      }
    }
  } //ctrl-c to exit
  return 0;
}

Am I missing something?
If someone can help me I'll be very grateful.

Thanks in advance!

I've finally managed to make it work.
In fact my issue was that I had the code of the UI and the code of PollingSample running at the same time.
I finally created two separate threads ( one for UI and one for LeapMotion ) and it worked like a charm.
I will close the thread since everything works now.
