Example

The following example shows how you can use the Explicit API frame to send an "Active Endpoints"
request to discover the active endpoints on a device with a 16-bit address of 0x1234.

Digi XBee® 3 Zigbee® RF Module
Offset Description
Set to the cluster ID that corresponds to the ZDO command being
17
sent.
18
0x0005 = Active Endpoints Request
19-20 Set to 0x0000 for ZDO transmissions (Profile ID 0x0000 is the
Zigbee device profile that supports ZDOs).
Sets the maximum number of hops a broadcast transmission can
21
traverse. If set to 0, the device sets the transmission radius to the
network maximum hops value.
All bits must be set to 0.
The required payload for a ZDO command. All multi-byte ZDO
23
parameter values (u16, u32, 64- bit address) must be sent in little
endian byte order.
The Active Endpoints Request includes the following payload:
24
[16-bit NwkAddrOfInterest]
Note The 16-bit address in the API example (0x1234) is sent in little
25
endian byte order (0x3412).
