Knowing the Reader Capabilities

The capabilities (or Read-Only properties) of the Reader can be known using ReaderCapabilites class. The reader capabilities include the following:

General Capabilities

  • Firmware Version – property

  • Model Name

  • Number of antennas supported

  • Number of GPIs & GPOs

  • UTC Clock supported

  • Receive Sensitivity Table

  • Periodic Tag Reporting Supported

  • Tag Phase Reporting supported

  • Tag Event Reporting Supported - Indicates the reader’s ability to report tag visibility state changes (New Tag, Tag Invisible, or Tag Visibility Changed.).

  • RSSI Filter Supported - Indicates the reader’s ability to report tags based on the signal strength of the back-scattered signal from the tag.

  • NXP Commands Supported - Indicates whether the reader supports NXP commands like Change EAS,set Quiet, Reset Quiet,Calibrate.

  • Impinj Command Supported - Gets the information on Impinj Command support.

Gen2 LLRP Capabilities

  • Block Erase supported

  • Block Write supported

  • Block PermaLock supported

  • State Aware Singulation supported

  • Maximum Number of Operation in Access Sequence

  • Maximum Pre-filters allowable per antenna

  • RF Modes

Regulatory Capabilities

  • Country Code

  • Communication Standard

  • UHF Band capabilities

  • Transmit Power table

  • Hopping enabled

  • Frequency Hop table (if hopping enabled, this table has the frequency information)

  • Fixed Frequency table (if hopping not enabled, this table contains the frequency list used by the reader. The one-based position of a frequency in this list is its channel index.)

Reader Identification

Reader ID and reader ID type (The reader identification can be MAC or EPC.)
