我正在使用 impinj octane SDK 3.6.0，我想做 EPC Gens2 标签过滤，但我的代码不能正常工作：

这是我的代码：

''''''''''''''''代码'''''''''''''''

   Settings setupFilter(Settings settings) {
        TagFilter TagFilter1 = settings.getFilters().getTagFilter1();
        TagFilter1.setBitCount(96);
        TagFilter1.setBitPointer(BitPointers.Epc);
        TagFilter1.setMemoryBank(MemoryBank.Epc);
        TagFilter1.setFilterOp(TagFilterOp.Match);
        TagFilter1.setTagMask("E280117000000213682C6B7B");
        settings.getFilters().setMode(TagFilterMode.OnlyFilter1);
        //settings.getFilters().setMode(TagFilterMode.UseTagSelectFilters);
        //settings.setFilters(null);
        
        //settings.getReport().setIncludeCrc(crc);
        settings.setReport(report);
     
    return settings;
   }



 public     Filter() {
    hostname = SampleProperties.hostname;

    reader = new ImpinjReader();
    startConexion();
    Settings settings = null;
    
    try {
        settings = reader.querySettings();
    } catch (OctaneSdkException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    
    // Gen2 Filtering
   settings = setupFilter(settings);


   try {
    reader.applySettings(settings);
   } catch (OctaneSdkException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
   }

}

'''''''''''''''''代码''''''''''''''''

我收到一条错误消息：

'''''''''''''''代码''''''''''''

''''''''''''代码''''''''''''''''

有什么建议么？
