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".

0 0x7E

MSB 1 0x00

Number of bytes between the length and the checksum

LSB 2 0x1A

3 0x11

4 0x01

Identifies the UART data frame for the host to correlate 

with a subsequent ACK (acknowledgement). If set to 0, 

no response is sent.

MSB 5 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
0x000000000000FFFF - Broadcast address

6 0x00
7 0x00
8 0x00
9 0x00

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.

LSB 14 0xFE

15 0xA0

Source endpoint for the transmission.

16 0xA1

Destination endpoint for the
transmission.

17 0x15

Cluster ID used in the transmission

18 0x54

19 0xC1

Profile ID used in the transmission

20 0x05

21 0x00

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 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). 

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

Data that is sent to the destination device

24 0x78
25 0x44
26 0x61
27 0x74
28 0x61

29 0x3A

0xFF - the 8 bit sum of bytes from offset 3 to this byte.
