Description
Start Delimiter
Length
MSB 1 0x00
LSB 2 0x1A
3 0x11
Number of bytes between the length and the checksum
Frame-specific Data Frame Type
Frame ID
Identifies the serial port data frame for the host to
correlate with a subsequent ACK (acknowledgement). If
set to 0, no response is sent.
4 0x01
MSB 5 0x00
6 0x00
Set to the 64-bit address of the destination device. The
following addresses are also supported:
0x0000000000000000 - Reserved 64-bit address for the
coordinator
7 0x00
64-bit Destination
Address
8 0x00
9 0x00
0x000000000000FFFF - Broadcast address
10 0x00
11 0x00
12 0x00
MSB 13 0xFF
Set to the 16-bit address of the destination device, if
known. Set to 0xFFFE if the address is unknown, or if
sending a broadcast.
16-bit Destination
Network Address
LSB 14 0xFE
15 0xA0

Source endpoint for the transmission.
Destination endpoint for the
transmission.

t
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.
Broadcast Radius
21 0x00
Bitfield of supported transmission options. Supported
values include the following:
0x01 - Disable ACK
0x20 - Enable APS encryption (if EE=1)
0x40 - Use the extended transmission timeout for this
destination
Enabling APS encryption decreases the maximum
number of RF payload bytes by 4 (below the value
reported by NP).
Transmit Options
22 0x00
Setting the extended timeout bit causes the stack to set
the extended transmission timeout for the destination
address. (See chapter 4.)
All unused and unsupported bits must be set to 0.
23 0x54
24 0x78
25 0x44
26 0x61
27 0x74
28 0x61
29 0x3A
Data Payload
Data that is sent to the destination device
Checksum
0xFF - the 8 bit sum of bytes from offset 3 to this byte.
Example: Send a data transmission to the coordinator (64-bit address of 0x00s) using a source endpoint
of 0xA0, destination endpoint 0xA1, cluster ID =0x1554, and profile ID 0xC105. Payload will be "TxData".
