case KEY_CHANGE://按键事件

case AF_INCOMING_MSG_CMD://接收数据事件,调用函数AF_DataRequest()接收数据

case ZDO_STATE_CHANGE:
//只要网络状态发生改变，就通过ZDO_STATE_CHANGE事件通知所有的任务。
//同时完成对协调器，路由器，终端的设置

SAMPLEAPP_SEND_PERIODIC_MSG_EVT, //周期性事件处理函数
SAMPLEAPP_SEND_PERIODIC_MSG_TIMEOUT ); //每5s处理一次

case SAMPLEAPP_PERIODIC_CLUSTERID: //收到广播数据
case SAMPLEAPP_FLASH_CLUSTERID: //收到组播数据

//接收数据，参数为接收到的数据
void SampleApp_MessageMSGCB( afIncomingMSGPacket_t *pkt )

//分析发送周期信息
void SampleApp_SendPeriodicMessage( void )

/接收属于本应用任务SampleApp的消息，以SampleApp_TaskID标记
MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive( SampleApp_TaskID );

消息结构体：
typedef struct
{
osal_event_hdr_t hdr; /* OSAL Message header */
uint16 groupId; /* Message's group ID - 0 if not set */
uint16 clusterId; /* Message's cluster ID */
afAddrType_t srcAddr; /* Source Address, if endpoint is STUBAPS_INTER_PAN_EP,
it's an InterPAN message */
uint16 macDestAddr; /* MAC header destination short address */
uint8 endPoint; /* destination endpoint */
uint8 wasBroadcast; /* TRUE if network destination was a broadcast address */
uint8 LinkQuality; /* The link quality of the received data frame */
uint8 correlation; /* The raw correlation value of the received data frame */
int8 rssi; /* The received RF power in units dBm */
uint8 SecurityUse; /* deprecated */
uint32 timestamp; /* receipt timestamp from MAC */
uint8 nwkSeqNum; /* network header frame sequence number */
afMSGCommandFormat_t cmd; /* Application Data */
} afIncomingMSGPacket_t;

typedef struct
{
uint8 TransSeqNumber;
uint16 DataLength; // Number of bytes in TransData
uint8 *Data;
} afMSGCommandFormat_t;

event+簇id+消息内容+内容大小
MSGpkt->hdr.event + MSGpkt->clusterId + MSGpkt->cmd.Data + MSGpkt->cmd.DataLength

uint16 SampleApp_ProcessEvent( uint8 task_id, uint16 events )触发接收或者发送
