Command descriptions for the XBee/XBee-PRO RF Module
XBee / XBee-PRO RF Modules 802.15.4 Product Manual 70
<Sleep Mode (Low Power)>
NonBeacon firmware
End Device - The DP command is used to set and read the time period of sleep for cyclic sleeping
remotes that are configured for Association but are not associated to a Coordinator. (i.e. If a device is
configured to associate, configured as a Cyclic Sleep remote, but does not find a Coordinator; it will
sleep for DP time before reattempting association.) Maximum sleep period is 268 seconds (0x68B0).
DP should be > 0 for NonBeacon systems.
EA (ACK Failures) command
<Diagnostics> The EA command is used to reset and read the count of ACK (acknowledgment)
failures. This parameter value increments when the module expires its transmission retries without
receiving an ACK on a packet transmission. This count saturates at its maximum value.
Set the parameter to “0” to reset count.
EC (CCA Failures) command
<Diagnostics> The EC command is used to read and reset the count of CCA (Clear Channel
Assessment) failures. This parameter value increments when the RF module does not transmit a
packet due to the detection of energy that is above the CCA threshold level (set with CA command).
This count saturates at its maximum value.
Set the EC parameter to “0” to reset count.
ED (Energy Scan) command
