ZPS_tsAplAfNodeDescriptor

The AF Node descriptor structure ZPS_tsAplAfNodeDescriptoris shown below.

typedef struct {
    uint32 :                      8;/* padding */
    uint32 eLogicalType :         3;
    uint32 bComplexDescAvail :    1;
    uint32 bUserDescAvail :       1;
    uint32 eReserved :            3; /* reserved */
    uint32 eFrequencyBand :       5;
    uint32 eApsFlags :            3;
    uint32 u8MacFlags :           8;
    uint16 u16ManufacturerCode;
    uint8 u8MaxBufferSize;
    uint16 u16MaxRxSize;
    uint16 u16ServerMask;
    uint16 u16MaxTxSize;
    uint8 u8DescriptorCapability;
} ZPS_tsAplAfNodeDescriptor;

where:

• eLogicalTypecontains 3 bits (bits 0-2) indicating the ZigBee device type of the node, as follows:

  • 000: Coordinator

  • 001: Router

  • 010: End Device

• bComplexDescAvailis set to 1 if there is a Complex descriptor available for node.

• bUserDescAvailis set to 1 if there is a User descriptor available for node.

• eReservedis reserved.

• eFrequencyBandcontains 5 bits detailing the frequency bands supported by the node, as follows (a bit is set to 1 if the corresponding band is supported):

  • Bit 0: 868-868.6 MHz

  • Bit 2: 902-928 MHz

  • Bit 3: 2400-2483.5 MHz

  • Bits 1 and 4 are reserved

• eApsFlagsis not currently supported and set to zero.

• eMacFlagscontains 8 bits (bits 0-7) indicating the node capabilities, as required by the IEEE 802.15.4 MAC sub-layer. These node capability flags are described in the table: Table.

• u16ManufacturerCodecontains 16 bits (bits 0-15) indicating the manufacturer code for the node, where this code is allocated to the manufacturer by the ZigBee Alliance.

• u8MaxBufferSizeis the maximum size, in bytes, of an NPDU (Network Protocol Data Unit).

• u16MaxRxSizeis the maximum size, in bytes, of an APDU (Application Protocol Data Unit). This value can be greater than the value of u8MaxBufferSize, due to the fragmentation of an APDU into NPDUs.

• u16ServerMaskcontains 8 bits (bits 0-7) indicating the server status of the node. This server mask is detailed in the table: Table.

• u16MaxTxSizeis the maximum size, in bytes, of the ASDU (Application Sub-layer Data Unit) in which a message can be sent (the message may actually be transmitted in smaller fragments)

• u8DescriptorCapabilitycontains 8 bits (bits 0-7) indicating the properties of the node that can be used by other nodes in network discovery, as follows:

Bit description of u8DescriptorCapability

Bit	Description
0	Set to 1 if Extended Active Endpoint List is available on the node, 0 otherwise.
1	Set to 1 if Extended Simple Descriptor List is available on the node, 0 otherwise.
2-7	Reserved
