ND (Node Discover) Command
NI (Node Identifier) Command
NO (Node Discover Options) 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 NO command
is used to suppress/include a self-response to
Node Discover commands. When NO=1 a module
doing a Node Discover will include a response
entry for itself.

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