Name and Description
Destination Node. Resolves an NI (Node Identifier) string to a physical address (case-
sensitive). The following events occur after the destination node is discovered:
<AT Firmware>
<API Firmware>
If there is no response from a module within (NT * 100) milliseconds or a parameter is
not specified (left blank), the command is terminated and an “ERROR” message is
returned. In the case of an ERROR, Command Mode is not exited. The radius of the DN
command is set by the BH command.
Scan Channels. Set/Read the list of channels to scan.
Coordinator - Bit field list of channels to choose from prior to starting network.
Router/End Device - Bit field list of channels that will be scanned to find a Coordinator/
Router to join.
Changes to SC should be written using WR command.
Bit (Channel):
Note: Setting SC to include more than 12 continuous channels could cause data to be
received on incorrect frequencies due to crosstalk issues with the EM250 at certain
power levels. See Appendix E for details.
Changing SC may result in not being able to communicate with long-range ‘-PRO’
modules from Digi
Scan Duration. Set/Read the scan duration exponent. Changes to SD should be
written using WR command.
Coordinator - Duration of the Active and Energy Scans (on each channel) that are
used to determine an acceptable channel and Pan ID for the Coordinator to startup on.
Router / End Device - Duration of Active Scan (on each channel) used to locate an
available Coordinator / Router to join during Association.
Scan Time is measured as:(# Channels to Scan) * (2 ^ SD) * 15.36ms - The number of
channels to scan is determined by the SC parameter. The XBee can scan up to 16
channels (SC = 0xFFFF).
Sample Scan Duration times (13 channel scan):
Node Join Time. Set/Read the time that a Coordinator/Router allows nodes to join.
This value can be changed at run time without requiring a Coordinator or Router to
restart. The time starts once the Coordinator or Router has started. The timer is reset
on power-cycle or when NJ changes.
Channel Verification. Set/Read the channel verification parameter. If JV=1, and the
network is an open network (NJ=0xFF), a router will verify the coordinator is on its
operating channel when joining or coming up from a power cycle. If a coordinator is not
detected, the router will leave its current channel and attempt to join a new PAN. If
JV=0, the router will continue operating on its current channel even if a coordinator is
not detected.
Aggregate Routing Notification. Set/read time between consecutive aggregate route
broadcast messages. If used, AR should be set on only one device to enable many-to-
one routing to the device. Setting AR to 0 only sends one broadcast
Association Indication. Read information regarding last node join request:
0x00 - Successful completion - Coordinator started or Router/End Device found and
joined with a parent.
0x21 - Scan found no PANs
0x22 - Scan found no valid PANs based on current SC and ID settings
0x23 - Valid Coordinator or Routers found, but they are not allowing joining (NJ expired)
0x27 - Node Joining attempt failed (typically due to incompatible security settings)
0x2A - Coordinator Start attempt failed‘
0xFF - Scanning for a Parent
0x2B - Checking for an existing coordinator
1. DL & DH are set to the extended (64-bit) address of the module with the matching
2. OK (or ERROR)\r is returned.
3. Command Mode is exited to allow immediate communication
1. The 16-bit network and 64-bit extended addresses are returned in an API
