AT commands
Networking and security commands
For more information about options that affect the behavior of the ND command Refer to the
description of the NO command for options which affect the behavior of the ND command.
WARNING! If the NT setting is small relative to the number of devices on the network,
responses may be lost due to channel congestion. Regardless of the NT setting, because
the random offset only mitigates transmission collisions, getting responses from all devices
in the network is not guaranteed.
Parameter range
20-byte printable ASCII string
Default
N/A
NT (Node Discover Timeout)
This command applies to the XBee/XBee-PRO S2C 802.15.4 RF Module.
Sets 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. Once the ND command has ended,
the base discards any response it receives.
Parameter range
0x1 - 0xFC (x 100 ms)
Default
0x19 (2.5 decimal seconds)
NO (Node Discovery Options)
This command applies to the XBee/XBee-PRO S2C 802.15.4 RF Module.
Use NO to suppress or include a self-response to ND (Node Discover) commands. When NO bit 1 = 1, a
device performing a Node Discover includes a response entry for itself.
Parameter range
0 - 1
Default
0x0
DN (Discover Node)
This command applies to the XBee/XBee-PRO S2C 802.15.4 RF Module.
Resolves an NI (Node identifier) string to a physical address (case sensitive).
The following events occur after DN discovers the destination node:
When DN is sent in Command mode :
1. The device sets DL and DH to the address of the device with the matching NI string.
The address selected (either 16-bit short address or 64-bit extended address) is chosen based
