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 status (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):
MY (Source Address) value<CR>
SH (Serial Number High) value<CR>
SL (Serial Number Low) value<CR>
DB (Received Signal Strength) value<CR>
NI (Node Identifier) value<CR>
<CR> (This is part of the response and not the end of command indicator.)
Node Discover Response (API format - data is binary (except for NI)):
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)
NI (Node Identifier) Command
<Networking {Identification}> The
NI command is used to set and
read a string for identifying a
particular node.
Rules:
• Register only accepts printable
ASCII data.
• A string can not start with a space.
• A carriage return ends command
• Command will automatically end when maximum bytes for the string have been
entered.
This string is returned as part of the ND (Node Discover) command. This identifier is
also used with the DN (Destination Node) command.
NT (Node Discover Time)
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 ability to respond before the
base ends the command. Once the ND command has ended, any response received
on the base would be discarded.
