Hi Friends,

End device joined to coordinator.

After coordinator is power off, end device do the rejoin.

So even another coordinator available, it doesn't join to that coordinator.

How can i make the end device to join another coordinator?

Hi Chen,

From the code, I could understand below one.

If the end device receives the leave request, it will start to rejoin with coordinator instead of resetting the device,

How can I make use of this code for my requirement?

for example, we have five coordinator and one end device.

First time the end device join with ZC1. Due to some problem in ZC1, it is power off.

then my end device need to join with one of available four ZCs.

But now the ZED doesn't join to available 4 ZC.

2) Is there any other way to remove end device by itself?

Can i initiate the ZDP_EndDeviceleaveReq at end device?

Regards,

Keerthi G.

I revise Cetri's code to serve your purpose. However, I don't have time to try it. Please have a look and test it.
void ZDApp_ProcessNetworkJoin( void ) 
{ 
  ... 
  else if ( devState == DEV_NWK_ORPHAN || devState == DEV_NWK_REJOIN ) 
  { 
    // results of an orphaning attempt by this device 
    if (nwkStatus == ZSuccess) 
    { 
+   if ( ZSTACK_END_DEVICE_BUILD )
 +   {
+    devState = DEV_NWK_DISC; 
+    devStartMode = MODE_REJOIN; 
+    _tmpRejoinState = true; 
+ 
+    if (ZG_DEVICE_ENDDEVICE_TYPE) 
+    { 
+      zgPollRate = POLL_RATE; 
+      ZDApp_SavedPollRate = zgPollRate; 
+      NLME_SetPollRate(0); 
+    } 
+ 
+    // For rejoin, specify the extended PANID to look for 
+    osal_cpyExtAddr( ZDO_UseExtendedPANID, _NIB.extendedPANID ); 
+ 
+    _NIB.nwkState = NWK_DISC; 
+ 
+    zdoDiscCounter = 3; 
+    NLME_NwkDiscTerm(); 
+ 
+    ZDApp_NetworkInit((uint16)(NWK_START_DELAY + ((uint16) (osal_rand() &EXTENDED_JOINING_RANDOM_MASK ))));
+   return;
+   }
  ...
}

Do you enable NC_RESTORE in your test? By the way, can you specify your Z-Stack version and what example do you test?

Z-Stack 2.3.1 is obsolete so please use latest Z-Stack.
