Route Record Indicator
Frame Type: 0xA1
The route record indicator is received whenever a device sends a ZigBee route record command.
This is used with many-to-one routing to create source routes for devices in a network.
Example: Suppose device E sends a route record that traverses multiple hops en route to data
collector device A 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 data collector will send the above API frame out its UART.
