Not getting tag read events from FX7500 via Ubuntu host SDK

I am developing a sample application based on:

* Ubuntu 16.04 host SDK with Java

I am successfully reading from inventory using:

reader.Actions.getReadTags(100)

I dont get any tag read events from:

reader.Events.setTagReadEvent(true); // this does not work!
reader.Events.setAttachTagDataWithReadEvent(true);
reader.Events.setBufferFullEvent(true); // this works!
reader.Events.addEventsListener(event_listener);

Any tips on what might be missing?

I am following "Programmer guide" in the SDK - Linux64_SDK/docs/Java/ProgrammersGuide/Generic Reader Interface/Managing Tags.htm

I have attached the full example ...

import com.mot.rfid.api3.*;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Scanner;

class EventHandler implements RfidEventsListener {
    // Read Event Notification
    public void eventReadNotify(RfidReadEvents e){
        TagData tag = e.getReadEventData().tagData;
        System.out.println("Event: Tag ID " + tag.getTagID());
        if (tag.getOpCode() == ACCESS_OPERATION_CODE.ACCESS_OPERATION_READ &&
            tag.getOpStatus() == ACCESS_OPERATION_STATUS.ACCESS_SUCCESS) {
            if (tag.getMemoryBankData().length() > 0) {
                System.out.println(" Mem Bank Data " + tag.getMemoryBankData());
            }
        }
    }
    // Status Event Notification
    public void eventStatusNotify(RfidStatusEvents e) {
        System.out.println("Event: Status Notification " + e.StatusEventData.getStatusEventType());
    }
}

public class ZebraTest {

    public static void main(String[] args) {
        System.out.format("Connect to reader");
        String hostname = "10.128.43.134"; // http://fx7500f0ddc7
        RFIDReader reader = new RFIDReader(hostname, 0, 0);
        EventHandler event_listener = new EventHandler();
        Scanner scanner = new Scanner(System.in);
        int scan_time = 5;
        // Trigger configuration
        TriggerInfo triggerInfo;
        triggerInfo = new TriggerInfo();
        triggerInfo.setEnableTagEventReport(true);
        triggerInfo.TagEventReportInfo.setReportNewTagEvent(TAG_EVENT_REPORT_TRIGGER.IMMEDIATE);
        triggerInfo.TagEventReportInfo.setReportTagBackToVisibilityEvent(TAG_EVENT_REPORT_TRIGGER.IMMEDIATE);
        triggerInfo.TagEventReportInfo.setReportTagInvisibleEvent(TAG_EVENT_REPORT_TRIGGER.IMMEDIATE);
        try {
            reader.connect();
            ZebraTest.printReaderCapabilities(reader);

                reader.Actions.Inventory.perform(null,triggerInfo,null);
                Thread.sleep(scan_time*1000);
                System.err.println("Inventory.stop()");

                    }
                }
                System.err.println("Actions.purgeTags()");
                reader.Actions.purgeTags();

Hi,

I am having the same problem when using the RFD2000 with TC20 Reader.

I am using the latest version available on the RFD2000 support page, which is Zebra_RFID_Mobile_API-2.2.7.0

The problem is that even enabling the RFID Tag Events while reading does not execute the RfidReadEvents handler.

I read through the Sled, the led lights green showing that it is reading, but it does not enter this Event:

@Override
        public void eventReadNotify (RfidReadEvents e) {
            end TagData [] myTags = Application.mConnectedReader.Actions.getReadTags (100);
            if (myTags! = null) {
                //Log.d("RFID_EVENT","l: "+ myTags.length);
                final Fragment fragment = getSupportFragmentManager (). findFragmentByTag (TAG_CONTENT_FRAGMENT);
                for (int index = 0; index 0) {
                            startlocatebeepingTimer (Application.TagProximityPercent);
                        }
                        if (fragment instanceof LocationingFragment)
                            ((LocationingFragment) fragment) .handleLocateTagResponse ();
                    } else {
                        if (Application.isAccessCriteriaRead &&! Application.mIsInventoryRunning) {
                            accessTagCount ++;
                        } else {
                            if (myTags [index]! = null && (myTags [index] .getOpStatus () == null || myTags [index] .getOpStatus () == ACCESS_OPERATION_STATUS.ACCESS_SUCCESS)
                                final int tag = index;

                                runOnUiThread (new Runnable () {
                                    @Override
                                    public void run () {
                                        if (Application.TAG_LIST_MATCH_MODE == true && Application.tagListFileExist == true)
                                            new MatchingTagsResponseHandlerTask (myTags [tag], fragment) .execute ();
                                        else
                                            new ResponseHandlerTask (myTags [tag], fragment) .execute ();
                                    }
                                });
                            }
                        }
                    }
                }
            }
        }

And with that I can not redeem the tags read to perform a later action.

This is occurring in Zebra_RFID_Mobile_API-2.2.7.0 demo application.

OBS: I updated the version of firmeware for the latest available on the site too, it being:
RFD2000-SAADXS00-001-R05D1

can anybody help me? Does anyone know if there is any other update to be made or if it is in fact an API problem available on the Site?
