Offset Description
MSB 5 The 64-bit address of the destination device (big
endian byte order). For unicast transmissions, set to
6
the 64-bit address of the destination device, or to
0x0000000000000000 to send a unicast to the
7
coordinator. Set to 0x000000000000FFFF for
8
broadcast.

LSB
12
MSB The 16-bit address of the destination device (big
13 endian byte order). Set to 0xFFFE for broadcast, or if
the 16-bit address is unknown.
LSB
14
15 Set to the source endpoint on the sending device
(0x41 arbitrarily selected).
16 Set to the destination endpoint on the remote device
(0x42 arbitrarily selected).
MSB Set to the cluster ID that corresponds to the ZCL
17 command being sent. 0x0000 = Basic Cluster.
LSB
18
MSB Set to the profile ID supported on the device (0xD123
19 arbitrarily selected).
LSB
20
21 Sets the maximum number of hops a broadcast
transmission can traverse. If set to 0, the
transmission radius will be set to the network
maximum hops value.
22 All bits must be set to 0.
Frame 23 Bitfield that defines the command type and other
control relevant information in the ZCL command. For more
information, see the ZCL specification.
