RFID Behavior Control
In addition to using default values, the RFID Sensor Platform supports the detailed RFID
configuration via the “apply_behavior” API command. This command is shown below
(see the RFID API Command Set document for a complete set of command definitions).
Parameter
Definition
action
Specifies the action to be taken.
The valid values are “START" and “STOP".
action_time
Specifies the millisecond epoch time to apply the behavior. If
zero or not included, the behavior is applied immediately.
behavior
Optional set of behavior parameters (see below).
id
The ID string assigned to this behavior
operation_mode
The embedded RFID module transmit operation mode.
The valid values are "Continuous" and "NonContinuous".
The default value is "NonContinuous".
link_profile
The RF Link Profile to be used for this behavior.
(see

)
The valid range is 0
– 4.
power_level
The power output level in dBm to be used for this behavior.
The valid range is 0
– 27.03.
dwell_time
The maximum amount of time (ms) spent on a particular virtual
port before switching to the next virtual port during an inventory
cycle. If this parameter is zero, the “inv_cycles" parameter may
not be zero.
The valid range is 0
– 65535.
inv_cycles
The maximum amount of inventory cycles to attempt on a
particular virtual port before switching to the next virtual port
during an inventory cycle. If this parameter is zero, the
“dwell_time" parameter may not be zero.
The valid range is 0
– 65535.
selected_state
Specifies the state of the “SL" flag to be used for this behavior
when specifying a select protocol operation. The valid values
are:
“Any", “Deasserted" and “Asserted".
session_flag
Specifies which inventory session flag is matched against the
state specified by “target_state". (see

)
The valid values are “S0", “S1", “S2" and “S3".
target_state
Specifies the state of the inventory session flag specified by
“session_flag" that are to apply the subsequent tag protocol
operation. (see

)
The valid values are “A" and “B".
q_algorithm
The specific Q algorithm being configured.
The valid values are “Fixed" and “Dynamic". When using a
“Fixed" algorithm, the number of time slots is 2^Q. When using
a “Dynamic" algorithm, the Smart Sensor Platform’s embedded
module will vary the number of slots dynamically based on the
number of tags responding.
fixed_q_value
The fixed Q value to use (valid when q_algorithm = Fixed).
The valid range of this parameter is 0
– 15.
repeat_until_no_tags
Specifies whether or not the singulation algorithm should
