AT commands
NI (Node Identifier)
A human-friendly name for the device. Use this string with network discovery commands in order to
easily identify devices on the network.
Use the ND (Network Discovery) command with this string as an argument to filter network discovery
results.
Use the DN (Discover Node) command with this string as an argument to resolve the 64-bit address of
a node with a matching NI string.
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 parameter determines the timeout value used for unicast transmissions from the local device.
The timeout is computed as (50 * NH) + 100 ms. A unicast transmission that does not receive an
acknowledgement within the timeout period is reported as a failed transmission.
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. NH is also used to set the maximum number of hops for broadcast
if BH > NH.
Parameter range
0 - 0xFF
Default
0x1E
BH (Broadcast Hops)
The number of hops that broadcast transmissions from the local device traverse. Unlike NH, this
parameter is a fixed number of hops and not used in timeout calculations.
Parameter range
0 - 0x1E
Default
0
AR (Aggregate Routing Notification)
Set or read the periodic time for broadcasting aggregate route messages. Setting AR enables many-
to-one routing from the broadcasting device using the concentrator mode determined by DO Bit 6.
Set AR to 0x00 to send only one broadcast.
