Create Source Route
Frame Type: 0x21
This frame creates a source route in the module. A source route specifies the complete route a packet should
traverse to get from source to destination. Source routing should be used with many-to-one routing for best
results.
Note: Both the 64-bit and 16-bit destination addresses are required when creating a source route. These are
obtained when a Route Record Indicator (0xA1) frame is received.
Example: Intermediate hop addresses must be ordered starting with the neighbor of the
destination, and working closer to the source. For example, suppose a route is found between A
and E as shown below.
A ' B ' C ' D ' E
If device E has the 64-bit and 16-bit addresses of 0x0013A200 40401122 and 0x3344, and if devices B, C, and
D have the following 16-bit addresses:
B = 0xAABB
C = 0xCCDD
D = 0xEEFF
The example above shows how to send the Create Source Route frame to establish a source route between A
and E.
Frame Fields Offset Example Description
Start Delimiter 00x7E
Length MSB 1 0x00
Number of bytes between the length and the checksum
LSB 2 0x14
Frame-specific Data Frame Type 30x21
Frame ID 4 0x00 The Frame ID should always be set to 0.
64-bit Destination
Address
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

11 0x11
LSB 12 0x22
16-bit Destination
Network Address
MSB 13 0x33 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 0x44
Route Command
Options
15 0x00 Set to 0.
Number of Addresses 16 0x03
The number of addresses in the
source route (excluding source
and destination).
Address 1
17 0xEE
(neighbor of
destination)
18 0xFF
Address 2 (closer hop 19 0xCC
Address of intermediate hop
20 0xDD
Address 3
21 0xAA
(neighbor of source)
22 0xBB
Checksum 23 0x01 0xFF - the 8 bit sum of bytes from offset 3 to this byte.
