AT commands
Default
0
NI (Node Identifier)
Stores the node identifier string for a device, which is a user-defined name or description of the
device. This can be up to 20 ASCII characters.
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)
NT (Node Discover Timeout)
Sets or displays the amount of time a base node waits for responses from other nodes when using the
ND (Node Discover) command. The NT value is transmitted with the ND command; remote nodes set
up a random hold-off time based on this time.
Sets or displays the network discovery back-off parameter for a device. This sets the maximum value
for the random delay that the device uses to send network discovery responses.
Parameter range
0x1 - 0xFC (x 100 ms)
Default
0x19 (2.5 decimal seconds)
ND (Network Discover)
This command reports the following information after a jittered time delay.
Node discover response when issued in Command mode:
16-bit Short Address (MY command)<CR>
Upper portion of the Long 64-bit Address (SH command)<CR>
Lower portion of the Long 64-bit Address (SL command)<CR>
Signal Strength in -dBm (DB command)<CR>
Node Identifier String (NI command)<CR>
<CR> (This is part of the response and not the end of command indicator.)
A second carriage return indicates the network discovery timeout (NT) has expired.
When operating in API mode and a Network Discovery is issued as a 0x08 or 0x09 frame, the response
contains binary data except for the NI string in the following format:
2 bytes for Short Source Address
4 bytes for Upper Long Address
4 bytes for Lower Long Address
1 byte for the signal strength in -dBm (two's complement representation)
NULL-terminated string for NI (Node Identifier) value (maximum 20 bytes without NULL
terminator)
