Abstract

The main way WSN API SDK can be extended is to add new "NET" modules into its palette. Customer can follow the general C API, structure, command, event and define ( called "NAL" layer Interface ) to add its own "NET" modules (ex: zigbee, bluetooth... ).

Basic In/Out Data Structure

Input Data Base Structure

typedef struct _InBaseData
{
   char            *psType; // 64 ( reference size )
   int           iSizeType; // Buffer size of psType
   char            *psData; // 2048 ( reference size )
   int           iSizeData; // Buffer size of psData 
   void           *pExtend; // Extend		
 }InBaseData;

Input Data Class Structure

typedef struct _InDataClass
{
   int                iTypeCount;  // Number of Type
   InBaseData  *pInBaseDataArray;  // Point of first BaseInData Array
   void                *pExtened;  // Extend
 }InDataClass;

Output Data Base Structure

typedef struct _OutBaseData
{
   char                  *psType;   // 64  ( reference size )
   int                 iSizeType;   // Buffer size of psType
   char                  *psData;   // 2048  ( reference size ) => If the data length is more than buffer size, user can reallocate this buffer point and re-assign the iSizeData.
   int                *iSizeData;   // Buffer size of psData
   void                 *pExtend;   // Extend
}OutBaseData;

typedef struct _OutDataClass
{
   int                 iTypeCount;  // Number of Type
   OutBaseData *pOutBaseDataArray;  // Point of the first BaseOutData Array
   void                 *pExtened;  // Extend		
}OutDataClass;

Structures for Network Interface

Interface's Capability

typedef struct _SNInfInfo
{
   char          sInfName[MAX_SN_INF_NAME];  // Interface Name
   char              sInfID[MAX_SN_INF_ID];  // Unique ID for identify (ex: MAC )
   OutDataClass               outDataClass;  // iTypeCount = 1,   psType: Info, psData:{"n":"SenHubList","sv":"","asm":"r"},{"n":"Topology","sv":"","asm":"r"},{"n":"Health","v":-1,"asm":"r"},
                                                                                       {"n":"Name","sv":"WSN0","asm":"r"}, {"n":"sw","sv":"1.0.0.1","asm":"r"},{"n":"reset","bv":0,"asm":"rw"}
   void                         *pExtened;   // Reserve for use
}SNInfterfaceInfo,SNInfInfo;

Get Multi Net Interfaces' Capability

typedef struct _SNInfInfos
{
    char          sComType[MAX_SN_COM_NAME];  // Communication Type Name
    int                                iNum;  // Number of Sensor Network Interface
    SNInfInfo        SNInfs[MAX_SN_INF_NUM];  // Detail Information of Sensor Network Interface
}SNInterfaceInfos,SNInfInfos,SNMultiInfInfo;

Update IoTGW Interface InfoSpec

typedef struct _SNInterfaceSpec
{
 char         sInfName[MAX_SN_INF_NAME];  // Interface Name
 char             sInfID[MAX_SN_INF_ID];  // Unique ID for identify (ex: 0000+MAC: remove '-' and ':' )
 InDataClass                inDataClass;  // iTypeCount = 1,   psType: Info, psData: {"n":"SenNodeList","sv":"","asm":"r"},{"n":"Topology","sv":"","asm":"r"},
                                                                                     {"n":"Health","v":-1,"asm":"r"},{"n":"Name","sv":"WSN0","asm":"r"},\
                                                                                     {"n":"sw","sv":"1.0.0.1","asm":"r"},{"n":"reset","bv":0,"asm":"rw"}
 void                         *pExtened;
}SNInterfaceSpec,SNInfSpec;
