the same time, the application periodically sends in broadcast the “Sink-Advertise” message

to keep the network alive and a “many-to-one-route-request” to update the routing tables of

all smartplugs in the network. The code sections that implement these functions are the

following:

Joined smartplugs list maintenance

for (i=0; i<APPLICATION_ADDRESS_TABLE_SIZE; i++) {

if (ticksSinceLastHeard[i] != 0xFFFF) {

if (++ticksSinceLastHeard[i] >

(MISS_PACKET_TOLERANCE * SEND_DATA_RATE)) {

//Remove the lost SmartPlug from the Plugs collection MP

CoordinatorType* pObjCoordinator = GetCoordinatorObj();

if(pObjCoordinator){

pObjSmartPlug = pObjCoordinator

>GetSmartPlug(pObjCoordinator,emberGetAddressTableRemoteNodeId(i));

if ( pObjSmartPlug )

{

id = pObjSmartPlug->ID;

pObjCoordinator-

>DelSmartPlug(pObjCoordinator,emberGetAddressTableRemoteNodeId(i));

sprintf( msg, "Node %d Deleted", id );

LCD_DisplayStringLineCol(Line8, 300, ( unsigned char * )msg );

emberSetAddressTableRemoteNodeId(i, EMBER_TABLE_ENTRY_UNUSED_NODE_ID);

emberSerialPrintf(APP_SERIAL,

"EVENT: too long since last heard, ");

emberSerialPrintf(APP_SERIAL,

"deleting address table index %x, status %x\r\n", i,

status);

ticksSinceLastHeard[i] = 0xFFFF;

}

}

}

}

}

Network maintenance

if (timeBeforeSinkAdvertise == 2) {

status = emberSendManyToOneRouteRequest(concentratorType,

10); // radius

emberSerialPrintf(APP_SERIAL,

"EVENT: sink send many-to-one route request,"

" status 0x%x\r\n", status);
