Nh (Maximum Unicast Hops); Bh (Broadcast Hops); Ar (Aggregate Routing Notification) - Digi XBee S2C Zigbee User Manual

AT commands
XCTU prevents you from exceeding the string limit of 20 characters for this command. If you
n
are using another software application to send the string, you can enter longer strings, but the
software on the device returns an error.
Use the ND (Network Discovery) command with this string as an argument to easily identify devices on
the network.
The DN command also uses this identifier.
Parameter range
A string of case-sensitive ASCII printable characters from 0 to 20 bytes in length. A carriage return
or a comma automatically ends the command.
Default
0x20 (an ASCII space character)

NH (Maximum Unicast Hops)

This command applies to the XBee/XBee-PRO Zigbee RF Module.
Sets or displays the maximum number of hops across the network. This limit sets the maximum
broadcast hops value (BH) and determines the unicast timeout.
The timeout is computed as (50 * NH) + 100 ms.
The default unicast timeout of 1.6 seconds (NH=0x1E) is enough time for data and the
acknowledgment to traverse approximately 8 hops.
If

BH (Broadcast Hops)

sending a broadcast transmission.
Parameter range
0 - 0xFF
Default
0x1E
BH (Broadcast Hops)
This command applies to the XBee/XBee-PRO Zigbee RF Module.
The maximum transmission hops for broadcast data transmissions.
Parameter range
0 - 0x1E
Default
0

AR (Aggregate Routing Notification)

This command applies to the XBee/XBee-PRO Zigbee RF Module.
Set or read the periodic time for broadcasting aggregate route messages. If used, these messages
enable many-to-one routing to the broadcasting device. Set AR to 0x00 to send only one broadcast, to
0xFF to disable broadcasts, or to other values for periodic broadcasts in 10 second units.
