RFID Behavior Control
In addition to using default values, the Intel® RFID Sensor Platform supports RFID behavior
configuration via API command. The parameters that can be controlled by this command are shown
below. See document 338178 RSP-Hx000 Message API 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 below).
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 – 31.5.
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".
target_state
Specifies which inventory session flag is matched against the
state specified by “target_state" (see below).
The valid values are “S0", “S1", “S2" and “S3".
session_flag
Specifies the state of the inventory session flag specified by
“session_flag" that are to apply the subsequent tag protocol
operation. 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 Intel®
RSP’s embedded
module will vary the number of slots dynamically based on
the number of tags responding.
