Generic Reader Interface

Overview

This section provides detailed information on how to develop RFID applications using RFID API3 generic interface. RFID API3 allows applications to talk to RFID Readers which support the LLRP Interface. LLRP is a standard specification for the network interface between the reader and its controlling software or hardware.

To develop applications using RFID API3 follow the steps beneath:

1. Connecting to Reader
2. Knowing Reader Capabilities
3. Configuring the Reader
4. Managing Events
5. Managing Tags
6. Basic operations
7. Advanced operations
8. Gen2 V2 Commands
9. NXP Commands
10. Impinj Commands
11. Disconnecting from the Reader

In general, if the function call fails, the function throws an exception. The application calls all APIs in try-catch block for handling exceptions. The following are the exceptions:

InvalidUsageException: This exception is thrown when the user passes invalid parameter

OperationFailureException: This exception is thrown when the requested operation is failed. The Exception contains the Operation result, status description, time stamp & vendor specific message for the operation failure.
