hi,
I'am working on a .NET MAUI app which scans the epc codes of RFID tags.
I want the RFID scanning behaviour to be like the 123RFID profile 'fastest read' .
The singulation settings are in this mode:
I try to replicate this behaviour using the MauiRfidSample which is included in the Zebra RFID Reader SDK for MAUI version 2.0.3.148 ( which is the latest on the Zebra website)
I've made the singulation settings the same as 123RFID:
var singulation = rfidReader.Config.Antennas.GetSingulationControl(1);
singulation.Session = SESSION.SessionS0;
singulation.Action.InventoryState = INVENTORY_STATE.InventoryStateAbFlip;
singulation.Action.SetPerformStateAwareSingulationAction(false);
singulation.Action.SLFlag = SL_FLAG.SlAll;
rfidReader.Config.Antennas.SetSingulationControl(1, singulation);
But the behaviour is strange:
In 123RFID every time I scan all the tags in the field are read. This is the behaviour I want.
In the mauirfidsample after the first scan seems mostly fine.
But when I scan again (also after restarting the application!) most of the time the tags are not read anymore!
But when I scan new tags they are read, its like the RFD40 'rembembers' that these tags are already scanned!
What is the problem here? can this be another setting I have to apply?
Another thing that I noticed, the version of the MAUI sdk is 2.0.3.148 and the version of 123RFID is 2.0.4.177
best regards,
Gijs

To read the MEMORY_BANK_USER content use the tag access mode during configure
rfidreader.Events.setAttachTagDataWithReadEvent(true);and the code for the event handler
class EventHandler implements RfidEventsListener {// Read Event Notificationpublic void eventReadNotify(RfidReadEvents e) {TagData tag = e.getReadEventData().tagData;if (tag.getOpCode() == ACCESS_OPERATION_CODE.ACCESS_OPERATION_READ&& tag.getOpStatus() == ACCESS_OPERATION_STATUS.ACCESS_SUCCESS) {Log.d(TAG, "eventReadNotify - tag id " + tag.getTagID() + " and mem bank " + tag.getMemoryBankData());}}}hi, was this an answer to my question?
My question was about singulation, not about reading the USER memory bank.
