LAUNCHXL-CC2640R2: Create HID BLE mouse

Hi! 

I'm trying to use LAUNCHXL-CC2640R2 with hid_emu_kbd_cc2640r2lp_app as an HID mouse. I used the original code and it worked fine, when the buttons are pressed on the board the device writes "a" or "b" on the pc/smartphone. So I enable the compiler variable USE_HID_MOUSE and then changed the place where hid keyboard reports are called then I putted hid mouse reports there, just like the code below:

/*********************************************************************
 * @fn      HidEmuKbd_handleKeys
 *
 * @brief   Handles all key events for this device.
 *
 * @param   keys - bit field for key events. Valid entries:
 *                 KEY_UP
 *                 KEY_RIGHT
 *
 * @return  none
 */
static void HidEmuKbd_handleKeys(uint8_t keys)
{
  if (keys & KEY_LEFT)
  {
    // Key Press.
    //HidEmuKbd_sendReport(KEY_LEFT_HID_BINDING);

      HidEmuKbd_sendMouseReport(-2);// Cursor moves to the left
    // Key Release.
    // NB: releasing a key press will not propagate a signal to this function,
    // so a "key release" is reported immediately afterwards here.
    //HidEmuKbd_sendReport(KEY_NONE);
  }

  if (keys & KEY_RIGHT)
  {
    // Key Press.
      HidEmuKbd_sendMouseReport(2);//Cursor moves to the right
    //HidEmuKbd_sendReport(KEY_RIGHT_HID_BINDING);

    // Key Release
    // NB: releasing a key press will not propagate a signal to this function,
    // so a "key release" is reported immediately afterwards here.
    //HidEmuKbd_sendReport(KEY_NONE);
  }
}

#ifdef USE_HID_MOUSE
/*********************************************************************
 * @fn      HidEmuKbd_sendMouseReport
 *
 * @brief   Build and send a HID mouse report.
 *
 * @param   buttons - Mouse button code
 *
 * @return  none
 */
static void HidEmuKbd_sendMouseReport(uint8_t buttons)
{
  uint8_t buf[HID_MOUSE_IN_RPT_LEN];

  buf[0] = 0;   // Buttons
  buf[1] = buttons;         // X
  buf[2] = 0;         // Y
  buf[3] = 0;         // Wheel
  buf[4] = 0;         // AC Pan

  HidDev_Report(HID_RPT_ID_MOUSE_IN, HID_REPORT_TYPE_INPUT,
                HID_MOUSE_IN_RPT_LEN, buf);
}
#endif // USE_HID_MOUSE

So I was expecting that when my board was paired it would create a mouse cursor on the central device and when the buttons were pressed the cursor would move to the corresponding directions, but nothing happens.
