ND (Node Discover) Command
NI (Node Identifier) Command
NT (Node Discover Time) Command
<Networking {Identification}> The ND command
is used to discover and report all modules on its
current operating channel (CH parameter) and
PAN ID (ID parameter). ND also accepts an NI
(Node Identifier) value as a parameter. In this
case, only a module matching the supplied identi-
fier will respond.
ND uses a 64-bit long address when sending and
responding to an ND request. The ND command
causes a module to transmit a globally addressed ND command packet. The amount of time
allowed for responses is determined by the NT (Node Discover Time) parameter.
In AT Command mode, command completion is designated by a carriage return (0x0D). Since two
carriage returns end a command response, the application will receive three carriage returns at
the end of the command. If no responses are received, the application should only receive one
carriage return. When in API mode, the application should receive a frame (with no data) and sta-
tus (set to ‘OK’) at the end of the command. When the ND command packet is received, the
remote sets up a random time delay (up to 2.2 sec) before replying as follows:
Node Discover Response (AT command mode format - Transparent operation):
Node Discover Response (API format - data is binary (except for NI)):
<Networking {Identification}> The NI command
is used to set and read a string for identifying a
particular node.
Rules:
This string is returned as part of the ND (Node Discover) command. This identifier is also used
with the DN (Destination Node) command.
<Networking {Identification}> The NT command
is used to set the amount of time a base node will
wait for responses from other nodes when using
the ND (Node Discover) command. The NT value
is transmitted with the ND command.
Remote nodes will set up a random hold-off time
based on this time. The remotes will adjust this
time down by 250 ms to give each node the abil-
ity to respond before the base ends the command. Once the ND command has ended, any
response received on the base would be discarded.

<CR> (This is part of the response and not the end of command indicator.)
2 bytes for MY (Source Address) value
4 bytes for SH (Serial Number High) value
4 bytes for SL (Serial Number Low) value
1 byte for DB (Received Signal Strength) value
NULL-terminated string for NI (Node Identifier) value (max 20 bytes w/out NULL terminator)
• Register only accepts printable ASCII data.

• A carriage return ends command
• Command will automatically end when maximum bytes for the string have been entered.
