nwkDescriptor

List of descriptors for each of the NetworkCount networks. One entry of type

NETWORK_DESCRIPTOR for each network found.

MAC_ENUM Status

Status after the search.

SUCCESS: successful search (minimum 1 network found)

NO_BEACON: no beacons detected during active scan

INVALID_PARAMETER: unsupported parameter or parameter out of range.

List entry, one per discovered network:

WORD panID

The 16-bit PAN identifier of the discovered network. The 2 highest-order bits of this

parameter are reserved and shall be set to 0.

BYTE logicalChannel

The current logical channel occupied by the network

BYTE stackProfile

A ZigBee stack profile identifier indicating the stack profile in use in the discovered

network.

BYTE zigBeeVersion

The version of the ZigBee protocol in use in the discovered network.

BYTE beaconOrder

This specifies how often the MAC sub-layer beacon is to be transmitted by a given device

on the network.

BYTE superFrameOrder

For beacon-enabled networks, i.e. beacon order < 15, this specifies the length of the

active period of the superframe.

BOOL permitJoining

Value of TRUE indicates that at least one ZigBee router on the network currently permits

joining, i.e. its NWK has been issued an NLME-PERMIT-JOINING primitive and the time

limit, if given, has not yet expired.

BYTE securityLevel

The security level used in a security-enabled PAN. This parameter is not specified in the

ZigBee v1.0 specification.
