    RFID3 API - Tag reading weird behaviour

    Christian Angulo



      I'm using RFID3 API to read a tag's EPC with a FX9500 reader (only one antenna attached). The way I'm doing so is through the TagAccess's ReadEvent and GetReadTags operations (see C# code below)...


        ReadAccessParams rap = new ReadAccessParams();
        rap.MemoryBank = MEMORY_BANK.MEMORY_BANK_EPC;
        this.Reader.Actions.TagAccess.ReadEvent(rap, null, null);
        TagData[] readTags = this.Reader.Actions.GetReadTags(100);


      ...what I've observed so far is that every tag that gets read successfully apears twice in "readTags" array.


      Is it the expected behaviour, or is it a bug?
      If this is normal, how can I avoid having each tag reported twice in readTags array?


      I've noticed the same occurs if I subscribe to "ReadNotify" event, since every time ReadEvent is called, two events with exactly the same data arrive for each tag in range.
