Offset Description
Transaction 24 A sequence number used to correlate a ZCL command
sequence with a ZCL response. (The hardware version response
number will include this byte as a sequence number in the
response.) The value 0x01 was arbitrarily selected.
Command 25 Since the frame control "frame type" bits are 00, this
ID byte specifies a general command. Command ID 0x00
is a Read Attributes command.
The payload for a "Read Attributes" command is a list
Attribute ID 26
of Attribute Identifiers that are being read.
Note
endian byte order (0x0300). All multi- byte ZCL header
and payload values must be sent in little endian byte
order.
27 0xFF minus the 8 bit sum of bytes from offset 3 to this
byte.
Bits Example Value Description
0-1 00 - Command acts across the entire profile.
2 0 - The manufacturer code field is omitted from the ZCL Frame
Header.
3 0 - The command is being sent from the client side to the server
side.
4 0 - Default response not disabled.
5-7 Set to 0.
The 16-bit Attribute ID (0x0003) is sent in little
