器件型号：LAUNCHXL-CC1352P

工具与软件：

环境中有多个协调人、他们都已关闭许可工作。如果路由器未能检测到加入网络的可能性、它将崩溃。

没错。此问题是由函数'bdb_filterNwkDisc'引起的。它可以像这样进行固定。

void bdb_filterNwkDisc(void)
{
  networkDesc_t* pNwkDesc;
  uint8_t i = 0;
  uint8_t ResultCount = 0, ResultTotal = 0;

  pBDBListNwk  = nwk_getNwkDescList();
  nwk_desc_list_release();

  pNwkDesc = pBDBListNwk;
  while (pNwkDesc)
  {
    ResultCount++;
    pNwkDesc = pNwkDesc->nextDesc;
  }

  ResultTotal = ResultCount;

  if(pBDBListNwk)
  {
    pNwkDesc = pBDBListNwk;

    if(pNwkDesc)
    {
      void *nextDesc = pNwkDesc->nextDesc;
      // "nextDesc" replace "pNwkDesc->nextDesc" because "pNwkDesc->nextDesc" is not corret after freed, fixed by LuoYiming 2025-03-10
      for ( i = 0; i < ResultTotal; i++, pNwkDesc = nextDesc ) 
      {
        nextDesc = pNwkDesc->nextDesc; // get the "nextDesc" before "pNwkDesc" is freed, fixed by LuoYiming 2025-03-10
        if ( nwk_ExtPANIDValid( ZDO_UseExtendedPANID ) == true )
        {
          // If the extended Pan ID is commissioned to a non zero value
          // Only join the Pan that has match EPID
          if ( osal_ExtAddrEqual( ZDO_UseExtendedPANID, pNwkDesc->extendedPANID) == false )
          {
            //Remove from the list
            bdb_nwkDescFree(pNwkDesc);
            ResultCount--;
            continue;
          }
        }
        else if ( zgConfigPANID != 0xFFFF )
        {
          // PAN Id is preconfigured. check if it matches
          if ( pNwkDesc->panId != zgConfigPANID )
          {
            //Remove from the list
            bdb_nwkDescFree(pNwkDesc);
            ResultCount--;
            continue;
          }
        }

        if ( pNwkDesc->chosenRouter != _NIB.nwkCoordAddress || _NIB.nwkCoordAddress == INVALID_NODE_ADDR )
        {
          // check that network is allowing joining
          if ( ZSTACK_ROUTER_BUILD )
          {
            if ( !pNwkDesc->routerCapacity )
            {
              //Remove from the list
              bdb_nwkDescFree(pNwkDesc);
              ResultCount--;
              continue;
            }
          }
          else if ( ZSTACK_END_DEVICE_BUILD )
          {
            if ( !pNwkDesc->deviceCapacity )
            {
              //Remove from the list
              bdb_nwkDescFree(pNwkDesc);
              ResultCount--;
              continue;
            }
          }
        }

        // check version of zigbee protocol
        if ( pNwkDesc->version != _NIB.nwkProtocolVersion )
          continue;

        // check version of stack profile, only matching profiles are supported
        if ( pNwkDesc->stackProfile != zgStackProfile  )
        {
            //Remove from the list
            bdb_nwkDescFree(pNwkDesc);
            ResultCount--;
            continue;
        }
      }
    }
  }

  //Notify the application about the remaining valid networks to join
  if(pfnFilterNwkDesc)
  {
    pfnFilterNwkDesc(pBDBListNwk, ResultCount);
  }
}
