程序如下，调用了NLME_PermitJoiningRequest(，设备依然能够入网，没有开启NV功能，协议栈版本ZStack-CC2530-2.2.0-1.3.0，请问一下是不是还需要设置什么参数？求论坛高手帮忙解答一下
case ZDO_STATE_CHANGE:
SampleApp_NwkState = (devStates_t)(MSGpkt->hdr.status);
if ( (SampleApp_NwkState == DEV_ZB_COORD)
|| (SampleApp_NwkState == DEV_ROUTER)
|| (SampleApp_NwkState == DEV_END_DEVICE) )
{
HalLedSet( HAL_LED_1,HAL_LED_MODE_ON );
#ifdef COORD
NLME_PermitJoiningRequest(0x00);
#endif
