RFID antenna

This module is a simple Python wrapper around the C library provided by the vendor libfetcp.so and libfeisc.so, using ctypes.

This antenna is supported, with IP connection (no USB): FEIG website

Installation

pip install obidrfid

Setup

The antenna is pre-configured with an IP address of 192.168.10.10. So you'll have to setup your network interface accordingly to communicate with it.

Once you can ping the RFID antenna, you're good to go.

The official C libraries must be installed on the system. Run ./install-libs.sh /usr/lib/ from the lib package downloaded from the vendor.

Usage

This moodule can be used as a standalone program to test the reader. The script obidrfid.py is installed by default.

Try obidrfid.py --help for usage.

Set IP address

obidrfid.py config --ip 192.168.10.10 --set-ip 192.168.142.10

This will change the reader ip address from 192.168.10.10 (the default) to 192.168.142.10.

Read transponders

obidrfid.py read --ip 192.168.142.10

This will conenct to the reader and start reading tags in range. Press Ctrl-C to exit.

Functions

rfid_connect(ip, port) can be used to connect to a reader. Returns the reader instance. Example reader = rfid_connect('192.168.10.10', 10001).

rfid_read(reader) read the transponders in range and returns an array of results with all the info (tr_type, dsfid and iid) for each transponder found.

rfid_reader_info(reader) returns the basic info on the reader (77).

rfid_reader_lan_configuration_read(reader) returns the reader LAN configuration.

rfid_reader_lan_configuration_write(reader, conf, ip) set the reader IP. conf is the configuration object previously obtained via rfid_reader_lan_configuration_read(), ip is an array representation of the IP [192, 168, 142, 1].

rfid_reader_system_reset(reader) performs a system reset on the reader. Used to persist changes made in the EPPROM.

Note to change the reader IP, you must perform the following steps:

• connect to the reader with rfid_connect()
• read the lan configuration with rfid_reader_lan_configuration_read()
• set the reader configuration with rfid_reader_lan_configuration_write()
• and finally perform a systen reset with rfid_reader_system_reset()

Additionally, the following functions can be used to interpret the error and status text: rfid_error_text(error_code) and rfid_status_text(status_code).
