/接收屬于本應用任務SampleApp的消息，以SampleApp_TaskID標記
MSGpkt = (afIncomingMSGPacket_t *)osal_msg_receive( SampleApp_TaskID );

消息結構體：
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
