CC2538: can't Send IAS Zone Enrollment request to CIE ?

Part Number: CC2538

hi all,

how to send broadcast message to PAN network .

the TI example snippet code , i can't see the boardcast . have any one give Suggest?

//uint8 zclSampleFireDetector_IAS_CIE_Address[8] = { 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF };

//#define AF_BROADCAST_ENDPOINT              0xFF
//#define SAMPLEFIREDETECTOR_ENDPOINT            17


    // zone enrollment request to CIE, only perform after writing cie address attribute value
    afAddrType_t zclCIE_Addr;

    zclCIE_Addr.addrMode = (afAddrMode_t)(Addr64Bit);
    osal_memcpy(zclCIE_Addr.addr.extAddr, zclSampleFireDetector_IAS_CIE_Address, Z_EXTADDR_LEN);
    zclCIE_Addr.endPoint = AF_BROADCAST_ENDPOINT;

    zclSS_IAS_Send_ZoneStatusEnrollRequestCmd( SAMPLEFIREDETECTOR_ENDPOINT,
                                               &zclCIE_Addr,
                                               zclSampleFireDetector_ZoneType,
                                               22, 0, 1);

ZStatus_t zclSS_IAS_Send_ZoneStatusEnrollRequestCmd( uint8 srcEP, afAddrType_t *dstAddr,
                                                     uint16 zoneType, uint16 manufacturerCode,
                                                     uint8 disableDefaultRsp, uint8 seqNum )
{
  uint8 buf[PAYLOAD_LEN_ZONE_ENROLL_REQUEST];

  buf[0] = LO_UINT16( zoneType );
  buf[1] = HI_UINT16( zoneType );
  buf[2] = LO_UINT16( manufacturerCode );
  buf[3] = HI_UINT16( manufacturerCode );

  return zcl_SendCommand( srcEP, dstAddr, ZCL_CLUSTER_ID_SS_IAS_ZONE,
                          COMMAND_SS_IAS_ZONE_STATUS_ENROLL_REQUEST, TRUE,
                          ZCL_FRAME_SERVER_CLIENT_DIR, disableDefaultRsp, 0,
                          seqNum, PAYLOAD_LEN_ZONE_ENROLL_REQUEST, buf );
}
