Name and Description
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. SC changes are not used until
the module is reset (FR, NR or power-up).
Bit (Channel):
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.
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
0x2A - Coordinator Start attempt failed‘
0xFF - Scanning for a Parent
Name and Description
Power Level. Select/Read the power level at which the RF module transmits conducted
power.
Power Mode. Set/read the power mode of the device. Enabling boost mode will improve
the receive sensitivity by 1dB and increase the transmit power by 2dB
Name and Description
API Enable. Enable API Mode.
The AP parameter is only applicable when using modules that contain the following
firmware versions:1.1xx (coordinator), 1.3xx (router/end device)
