WEBENCH® Tools/CC2530: How to change communication from 64bit MAC to 16bit ShortAdd

I used 64 bit MAC for commm between coordinator and router now I want to change it to 16 bit short address.
Can you explain what changes I should make for this in following section of code. I know how to get the short address.

static void DEEPPayloadProcess(uint8 *buff,uint16 length)
{
GenericApp_DstAddr.addrMode = (afAddrMode_t)Addr64Bit;
GenericApp_DstAddr.endPoint = GENERICAPP_ENDPOINT;
GenericApp_DstAddr.addr.extAddr[0] = buff[1];
GenericApp_DstAddr.addr.extAddr[1] = buff[2];
GenericApp_DstAddr.addr.extAddr[2] = buff[3];
GenericApp_DstAddr.addr.extAddr[3] = buff[4];
GenericApp_DstAddr.addr.extAddr[4] = buff[5];
GenericApp_DstAddr.addr.extAddr[5] = buff[6];
GenericApp_DstAddr.addr.extAddr[6] = buff[7];
GenericApp_DstAddr.addr.extAddr[7] = buff[8];

if ( AF_DataRequest( &GenericApp_DstAddr, &GenericApp_epDesc,
GENERICAPP_CLUSTERID,
length,
buff,
&GenericApp_TransID,
AF_DISCV_ROUTE, AF_DEFAULT_RADIUS ) == afStatus_SUCCESS )
{

}

Use the following

GenericApp_DstAddr.addrMode = (afAddrMode_t)Addr16Bit;
GenericApp_DstAddr.endPoint = GENERICAPP_ENDPOINT;
GenericApp_DstAddr.addr.extAddr[0] = destination short address low byte;
GenericApp_DstAddr.addr.extAddr[1] = destination short address high byte;

I don't remember exactly extAddr[0] is low or high byte of short address so you might try it to know,.

should i also change into following section???

#if defined( DEEP_COORDINATOR )
DEEP_UART_Init();
UART1_Init();
Set_Coord_PANID();

#endif
GenericApp_DstAddr.addrMode = (afAddrMode_t)AddrNotPresent;
GenericApp_DstAddr.endPoint = 0;
GenericApp_DstAddr.addr.shortAddr = 0;

// Fill out the endpoint description.
GenericApp_epDesc.endPoint = GENERICAPP_ENDPOINT;
GenericApp_epDesc.task_id = &GenericApp_TaskID;
GenericApp_epDesc.simpleDesc
= (SimpleDescriptionFormat_t *)&GenericApp_SimpleDesc;
GenericApp_epDesc.latencyReq = noLatencyReqs;

// Register the endpoint description with the AF
afRegister( &GenericApp_epDesc );

You should change GenericApp_DstAddr.addrMode , GenericApp_DstAddr.endPoint, and GenericApp_DstAddr.addr.shortAddr right before you call AF_DataRequest

NLME_GetShortAddr()
Is it right function to get the shortAddr?????????????
In my application first I connect router and coordinator by UART and get the router's shortAdd via UART to the coordinator than coordinator communicates to the router using its shortaddress.???????
Am I doing on right way or not?? Because I didn't get any response from router

NLME_GetShortAddr get the short address of device itself. If you want to send message from coordinator to device, the destination address should be short address of router.

Thank you it works now!!!
Thank you so much for your support....... :)

If I want to set shortAddr of each router and coordinator as first two bytes of its MAC address??
In this way can communication possible??

You cannot assign short address. It’s done by Z-Stack automatically.

Can we send data to the router outside the network...??
Because we think that in case of coordinator failure we have to take out all the router devices and connect to new coordinator to configure them like PAN ID and get short address of router etc.
So is there any way to send data from coordinator to router outside network????
Because we think that instead of connecting router and coordinator through UART, we will make them do wireless configuration......

You cannot do that.

how to read or write any variable into non volatile memory ??

You can use osal_nv_read and osal_nv_write.
