ZPS_eAplZdpNodeDescRequest

ZPS\_teStatus ZPS\_eAplZdpNodeDescRequest\(
    PDUM\_thAPduInstance hAPduInst,
    ZPS\_tuAddress uDstAddr,
    bool bExtAddr,
    uint8 *pu8SeqNumber,
    ZPS\_tsAplZdpNodeDescReq *psZdpNodeDescReq);

Description

This function requests the Node descriptor of the node with a particular network address. The function sends a Node_Desc_req request either to the relevant node or to another node that may hold the required information in its primary discovery cache.

The network address of the node of interest must be specified in the request, which is represented by the structure below (further detailed in Section 9.2.2.4).

typedef struct {
     uint16 u16NwkAddrOfInterest;
} ZPS_tsAplZdpNodeDescReq;

The required Node descriptor is received in a Node_Desc_rsp response, which should be collected using the function ZQ_bZQueueReceive() and stored in a structure of type ZPS_tsAplZdpNodeDescRsp(detailed in Section 9.2.3.3).

Parameters

  • hAPduInst: Handle of APDU instance in which request is sent

    • TRUE: 64-bit IEEE (MAC) address

    • FALSE: 16-bit network address

  • *pu8SeqNumber: Pointer to sequence number of request
