XBee‐PRO PKG‐R® RS‐232 RF Modem – 802.15.4 ‐ Product Manual v1.xAx
RR (XBee Retries) Command
SC (Scan Channels) Command
SD (Scan Duration) Command
<Networking {Addressing}> The RR command is
used set/read the maximum number of retries
the modem will execute in addition to the 3
retries provided by the 802.15.4 MAC. For each
XBee retry, the 802.15.4 MAC can execute up to
3 retries.
This values does not need to be set on all modems for retries to work. If retries are enabled, the
transmitting modem will set a bit in the Digi RF Packet header which requests the receiving
modem to send an ACK (acknowledgement). If the transmitting modem does not receive an ACK
within 200 msec, it will re-send the packet within a random period up to 48 msec. Each XBee retry
can potentially result in the MAC sending the packet 4 times (1 try plus 3 retries). Note that retries
are not attempted for packets that are purged when transmitting with a Cyclic Sleep Coordinator.
<Networking {Association}> The SC command is
used to set and read the list of channels to scan
for all Active and Energy Scans as a bit field.
This affects scans initiated in command mode [AS
(Active Scan) and ED (Energy Scan) commands]
and during End Device Association and
Coordinator startup.
<Networking {Association}> The SD command is
used to set and read the exponent value that
determines the duration (in time) of a scan.
End Device (Duration of Active Scan during
Association) - In a Beacon system, set SD = BE of
the Coordinator. SD must be set at least to the
highest BE parameter of any Beaconing
Coordinator with which an End Device or
Coordinator wish to discover.
Coordinator - If the ‘ReassignPANID’ option is set on the Coordinator [refer to A2 parameter],
the SD parameter determines the length of time the Coordinator will scan channels to locate
existing PANs. If the ‘ReassignChannel’ option is set, SD determines how long the Coordinator will
perform an Energy Scan to determine which channel it will operate on.
Scan Time is measured as ((# of Channels to Scan) * (2 ^ SD) * 15.36ms). The number of
channels to scan is set by the SC command. The XBee RF Modem can scan up to 16 channels (SC
= 0xFFFF). The XBee PRO RF Modem can scan up to 12 channels (SC = 0x1FFE).
