Hi all ：

there are 4 ZEDs ，1 ZR and 1 ZC in the network.

those ZEDs were all connect to the ZR ， and the ZR connect the ZC。

i set a timer to sending the Active EP request from ZR to ZC again and again to checking the link state.

  if(events & NETLINK_CHECK_EVT)
  {      
     if(Being_Link == FALSE)
     {
      #ifdef LEDShow
        HalLedSet ( HAL_LED_2, HAL_LED_MODE_OFF);
        if(!BasicReset)
          HalLedBlink ( HAL_LED_1, 0,LOST_NETWROK_FLASH, LOST_NETWROK_CYCLE );
      #endif 
     }
     else
     {
      #ifdef LEDShow
        HalLedSet ( HAL_LED_1 | HAL_LED_2, HAL_LED_MODE_OFF);
      #endif
     }
     
     if(FailedLinkCnt >= LoseLinkCnt_Limit)
     {
       Being_Link = FALSE;
       FailedLinkCnt =0;
     }
     else
     {
       FailedLinkCnt++;
     }
     
     ZDP_ActiveEPReq(&Coordinator_dstAddr,Coordinator_dstAddr.addr.shortAddr,0);
     osal_start_timerEx( zclVrouter_TaskID, NETLINK_CHECK_EVT, NETLINK_CHECK_CYCLE);//8second
     return ( events ^ NETLINK_CHECK_EVT );
  }

this network running 30~40 minutes latter， i found that all ZEDs and ZR were “lose connect” with ZC.

Those ZED sent a Msg to ZC via ZR ， but ZR receive it and didn't resend to ZC.

and there is not any ACtive EP request more....

here is the log ：ZR lose connect with ZC.rar

Which Z-Stack version and example do you run as ZR?

Hi yikai
it is zstack1.2.2a

Do you modify anything to it?

0 The Seven over 9 years ago in reply to YiKai Chen

Guru 11440 points

just add the timer to send ACTIVE EP request again and again。

as show above！

I suspect your ZR is not working when this happens. As you can see, there is no active endpoint request from ZR to ZC at this moment. I would suggest you debug to see where ZR stuck.

where should i set the break point？

0 YiKai Chen over 9 years ago in reply to The Seven

Guru 735685 points

You can try to set it in NETLINK_CHECK_EVT and see if it is hit after the problem happens.

Hi yikai ！
when the problem happens， it could hit the break point in the NETLINK_CHECK_EVT。

and i saw it always running the

osal_start_timerEx( zclVrouter_TaskID, NETLINK_CHECK_EVT, NETLINK_CHECK_CYCLE);//8second

but never going into NETLINK_CHECK_EVT again！

Since it is hit, do you see active endpoint request is sent in Ubiqua Packet Analyzer?

0 The Seven over 9 years ago in reply to YiKai Chen

Guru 11440 points

No ，there is not more active endpoint request in ubiqua， but IAR shows it had run below code

ZDP_ActiveEPReq(&Coordinator_dstAddr,Coordinator_dstAddr.addr.shortAddr,0);
osal_start_timerEx( zclVrouter_TaskID, NETLINK_CHECK_EVT, NETLINK_CHECK_CYCLE);//8second

You should check return value of ZDP_ActiveEPReq when this issue happens.

it （AF_DataRequest）returns 0x10

#define afStatus_SUCCESS            ZSuccess           /* 0x00 */
#define afStatus_FAILED             ZFailure           /* 0x01 */
#define afStatus_INVALID_PARAMETER ZInvalidParameter /* 0x02 */
#define afStatus_MEM_FAIL           ZMemError          /* 0x10 */
#define afStatus_NO_ROUTE           ZNwkNoRoute        /* 0xCD */

i think that is i forgot to free the memory when receive active ep response ！！！！

#ifdef NetLinkCheck       
   case Active_EP_rsp:
     {
       pActiveEndpoint = ZDO_ParseEPListRsp( pMsg );
       if(pActiveEndpoint->status == ZSuccess)
       {
         FailedLinkCnt =0;
         if(Being_Link == FALSE)
         {
           Being_Link = TRUE;
           #ifdef LEDShow
             HalLedBlink ( HAL_LED_1 | HAL_LED_2, 5, CANCEL_EZMODE_FLASH, CANCEL_EZMODE_CYCLE ); 
             UserEvtItem = Turn_Off_LED;
             osal_start_timerEx( zclVrouter_TaskID, USERAPP_EVT, 1000 );
           #endif 
         }
       }
       osal_mem_free( pActiveEndpoint );
     }
     break;
#endif

maybe add this code should be work！！！！！

BR!

This error mean there is not enough memory. You have to check if there is memory leak in your application.
