终端设备入网问题

NLME_GetCoordShortAddr 确实是获取父节点的地址，
你的coordinator 是0x0000 ，coordinator 掉线后，end device 会连入路由。这是你无法选择，当你一个设备入网时会选择一个信号质量最好的入网，这是你无法改变的，你直接尝试做些逻辑看看能不能实现。

改动后的函数如下，是否正确？

void ZDO_beaconNotifyIndCB( NLME_beaconInd_t *pBeacon )
{
// Pass the beacon Indication to another task if it registers the callback
// Otherwise, process the beacon notification here.
if (zdoCBFunc[ZDO_BEACON_NOTIFY_IND_CBID] != NULL )
{
zdoCBFunc[ZDO_BEACON_NOTIFY_IND_CBID]( (void*)pBeacon );
}
else
{
networkDesc_t *pNwkDesc;
networkDesc_t *pLastNwkDesc;
uint8 found = false;

// Add the network to the Network Descriptor List
pNwkDesc = NwkDescList;
pLastNwkDesc = NwkDescList;
while (pNwkDesc)
{
if ((pNwkDesc->panId == pBeacon->panID) &&
(pNwkDesc->logicalChannel == pBeacon->logicalChannel))
{
found = true;
break;
}
pLastNwkDesc = pNwkDesc;
pNwkDesc = pNwkDesc->nextDesc;
}

// If no existing descriptor found, make a new one and add to the list
if (found == false)
{
pNwkDesc = osal_mem_alloc( sizeof(networkDesc_t) );
if ( !pNwkDesc )
{
// Memory alloc failed, discard this beacon
return;
}

// Clear the network descriptor
osal_memset( pNwkDesc, 0, sizeof(networkDesc_t) );

// Initialize the descriptor
pNwkDesc->chosenRouter = 0;//默认INVALID_NODE_ADDR;
pNwkDesc->chosenRouterDepth = 0;//默认0xFF;

// Save new entry into the descriptor list
if ( !NwkDescList )
{
NwkDescList = pNwkDesc;
}
else
{
pLastNwkDesc->nextDesc = pNwkDesc;
}
}

// Update the descriptor with the incoming beacon
pNwkDesc->stackProfile = pBeacon->stackProfile;
pNwkDesc->version = pBeacon->protocolVersion;
pNwkDesc->logicalChannel = pBeacon->logicalChannel;
pNwkDesc->panId = pBeacon->panID;
pNwkDesc->updateId = pBeacon->updateID;

// Save the extended PAN ID from the beacon payload only if 1.1 version network
if ( pBeacon->protocolVersion != ZB_PROT_V1_0 )
{
osal_cpyExtAddr( pNwkDesc->extendedPANID, pBeacon->extendedPanID );
}
else
{
osal_memset( pNwkDesc->extendedPANID, 0xFF, Z_EXTADDR_LEN );
}

// check if this device is a better choice to join...
// ...dont bother checking assocPermit flag is doing a rejoin
if ( ( pBeacon->LQI > gMIN_TREE_LQI ) &&
( ( pBeacon->permitJoining == TRUE ) || ( _tmpRejoinState ) ) )
{
uint8 selected = FALSE;
uint8 capacity = FALSE;

#if defined ( ZIGBEEPRO )
if ( ((pBeacon->LQI > pNwkDesc->chosenRouterLinkQuality) &&
(pBeacon->depth < MAX_NODE_DEPTH)) ||
((pBeacon->LQI == pNwkDesc->chosenRouterLinkQuality) &&
(pBeacon->depth < pNwkDesc->chosenRouterDepth)) )
{
selected = TRUE;
}
#else
if ( pBeacon->depth < pNwkDesc->chosenRouterDepth )
{
selected = TRUE;
}
#endif

if ( ZSTACK_ROUTER_BUILD )
{
capacity = pBeacon->routerCapacity;
}
else if ( ZSTACK_END_DEVICE_BUILD )
{
capacity = pBeacon->deviceCapacity;
}

//if ( ( (capacity) || ( pBeacon->sourceAddr == _NIB.nwkCoordAddress ) ) && (selected) )

if ( ( (capacity) || ( pBeacon->sourceAddr == 0x0000) ) && (selected) )
{
// this is the new chosen router for joining...
pNwkDesc->chosenRouter = pBeacon->sourceAddr;
pNwkDesc->chosenRouterLinkQuality = pBeacon->LQI;//这里要改？
pNwkDesc->chosenRouterDepth = 0;//默认pBeacon->depth;
}

if ( pBeacon->deviceCapacity )
pNwkDesc->deviceCapacity = 1;

if ( pBeacon->routerCapacity )
pNwkDesc->routerCapacity = 1;
}
}
}

另外，

1.该函数的下面是否要修改？

// Initialize the descriptor
pNwkDesc->chosenRouter = 0;//默认INVALID_NODE_ADDR;
pNwkDesc->chosenRouterDepth = 0;//默认0xFF;

2.LQI需要修改吗？Depth改为0是否可以？

pNwkDesc->chosenRouter = pBeacon->sourceAddr;
pNwkDesc->chosenRouterLinkQuality = pBeacon->LQI;//这里要改？
pNwkDesc->chosenRouterDepth = 0;//默认pBeacon->depth;

2.做了上述修改后，终端在协调器断电后不会加入路由，再协调器再次上电后会加入协调器，是否可以实现？
