CC3200 Idle_Profile, example code, Green/Orange LED can not turn-off?

Dear all,

When the Idle-Profile example code run at CC3200 LaunchPad, the Green/Orange LED are always ON.

Even I try to add code to turn off the LEDs, (for example: GPIO_IF_LedOff(MCU_ALL_LED_IND);)

those two LEDs will be turned ON after run to the below command.

  osi_MsgQRead(&g_tWkupSignalQueue, &ucQueueMsg, OSI_WAIT_FOREVER);

Is there idea for this strange symptom?

Thanks!
