请教一下，想CC2640R2F例程中SimpleBLEbroadcaster 通过按键控制 shutdown和唤醒，在设置shutdown按键时候，发现第一次按下手机搜不到；但是第二次按下去，又会搜索到simpleBLEbroadcaster，shutdown按键变成了唤醒按键，这是为什么，希望能够得到指导，谢谢

这是按键的部分，按下shutdown按键后，再按一次，设备又可以被手机搜到了
static void GUA_HandleKeys(uint8 GUA_keys)
{
  //按键
  if ( GUA_keys & GUA_KEY_VALUE )
  {
      GUA_Led_Set(HAL_LED_2, HAL_LED_MODE_OFF);
      Power_shutdown(0, 0);
  }

  if ( GUA_keys & GUA_KEY_VALUE_2 )
  {
    GUA_Led_Set(HAL_LED_2, HAL_LED_MODE_ON);        
  }
}

    看下这里，是不是将其设为唤醒引脚了

    /** @brief Configure wakeup (from shutdown) on pins
 *
 *  @param aPinCfg #PIN_Config list identifying pin ID and relevant pin
 *                 configuration as one of:
 *                 - #PINCC26XX_NO_WAKEUP      (default)
 *                 - #PINCC26XX_WAKEUP_POSEDGE
 *                 - #PINCC26XX_WAKEUP_NEGEDGE

 *
 *  @par Usage
 *       @code

 *  @note A wake-up event to wake up from shutdown is not detected until

 *  is initiated but before actual shutdown are not captured and thus will
 *  not cause the device to wake up.
