ZigBee Node Type• ZigBee Node Type :

– Coordinator • Forms network• Routes packets• Security Trust Center• Allows nodes to join network

– Router• Join network• Routes packets• Allows nodes to join network

– End-Device• Join network• Battery operated and may sleep• Smallest code size

MAC APINAME DESCRIPTION

MAC_MlmeResetReq() This direct execute function resets the MAC.

MAC_MlmeScanReq() This function initiates an energy detect, active, passive, or orphan scan on one or more channels.

MAC_MLME_SCAN_CNF Callback Function Event. This event sends data from the MAC to the application.

MAC_MlmeSetReq() This direct execute function sets an attribute value in the MAC PIB.

MAC_MlmeStartReq() This function is called by a coordinator or PAN coordinator to start or reconfigure a network.

MAC_MLME_START_CNF Callback Function Event.

MAC_MlmeAssociateReq() This function sends an associate request to a coordinator device.

MAC_MLME_ASSOCIATE_IND Callback Function Event.

MAC_MlmeAssociateRsp() This function sends an associate response to a device requesting to associate.

MAC_MLME_ASSOCIATE_CNF Callback Function Event. 5

NAME DESCRIPTION

MAC_BEACON_NOTIFY_IND Callback Function Event. This event sends data from the MAC to the application.

MAC_MLME_SYNC_LOSS_IND Callback Function Event.

MAC_MlmeOrphanRsp() This function is called in response to an orphan notification from a peer device.

MAC_McpsDataReq() This function sends application data to the MAC for transmission in a MAC data frame.

MAC_MCPS_DATA_IND This event sends data from the MAC to the application.

MAC_MCPS_DATA_CNF Callback Function Event.

MAC_McpsPollReq() This function is used to request pending data from the coordinator.

MAC_MCPS_POLL_CNF Callback Function Event.

MAC_McpsPurgeReq() This function purges and discards a data request from the MAC data queue.

MAC_MCPS_PURGE_CNF Callback Function Event.

Directory Hierarchy in Developing An Application

HAL （ Hardware (H/W) Abstraction Layer）：硬體層目錄，包含有與硬體相關的配置和驅動及操作函數。 

MAC ： MAC層目錄，包含了MAC層的參數配置文件及其 MAC 的 LIB庫的函數介面文件。

NWK （ ZigBee Network Layer）：網路層目錄，含網路層配置參數文件及網絡層的函數介面文件， APS層的函數介面。

Profile ： AF （ Application Framework）層目錄，包含 AF層處理函數文件。

ZDO （ ZigBee Device Objects）： ZDO目錄。

Security：安全層目錄，安全層處理函數，比如加密函數等。 

15

Directory Hierarchy in Developing An Application Con.

APP （ Application Programming）：應用層目錄，這是用戶創建各種不同動作的區域，在這個目錄中包含了應用層的內容和這個項目的主要內容。

MT （ Monitor Test）：實現通過序列埠可控各層，於各層進行直接溝通。

OSAL （ Operating System (OS) Abstraction Layer ）： protocol stack的操作系統。

Services：地址處理函數目錄，包括著地址模式的定義及地址處理函數。 

Tools：工程配置目錄，包括空間劃分及 Z-Stack相關配置信息。

ZMac ： MAC層目錄，包括MAC層參數配置及MAC層 LIB API回傳處理。

ZMain：主函數目錄，包括初始化函數及硬件配置。

Output：輸出文件目錄，這個 EW8051 IDE自動生成的。

Demo 情境 1

• Non enable security over NWK layer• Coordinator– CollectorEB.hex

• Sensor– SensorEB.hex

25

情境 2

• Enable security over NWK layer• Network key is preconfigured (Set

zgPreConfigkeys = TRUE in ZGlobals.c)• Setting preconfigured Network key ( Defaultkey =

{KEY} in nwk_globals.c)• Coordinator– CollectorEB_ssec.hex

• Sensor– SensorEB_ssec.hex– SensorEB_sseck.hex (different key)

26

情境 3

• Enable security over NWK layer• Network key is not preconfigured (Set

zgPreConfigkeys = FALSE in ZGlobals.c)• Setting preconfigured Network key ( Defaultkey =

{KEY} in nwk_globals.c)• Coordinator– CollectorEB_ssecf.hex

• Sensor– SensorEB_ssecf.hex
