當看到標籤時，LLRP Impinj無法看到天線端口

我目前正在連接Impinj高速公路閱讀器220，並且我有2個天線連接到它。當看到標籤時，LLRP Impinj無法看到天線端口

當我加載Impinj MultiReader應用程序並切換顯示天線端口時，它會將RFID標籤被讀取的天線返回到應用程序。

我目前使用C＃連接到閱讀器（儘管我相信所有語言的SDK都是相似的）。以下是我使用的示例代碼，但是我不知道哪個配置選項會啓用讀取天線端口的功能。

有人請讓我知道哪個配置選項打開選項，以便AntennaID與標籤一起返回嗎？

     msg.ROSpec.ROReportSpec.TagReportContentSelector = new PARAM_TagReportContentSelector(); 

     MSG_ADD_ROSPEC_RESPONSE rsp = reader.ADD_ROSPEC(msg, out msg_err, 2000);

我終於發現瞭如何去做。

在上述例子中我只是刪除

msg.ROSpec.ROReportSpec.TagReportContentSelector = new PARAM_TagReportContentSelector();

並用

PARAM_TagReportContentSelector reportContent = new PARAM_TagReportContentSelector(); 
reportContent.EnableAntennaID = true; 

msg.ROSpec.ROReportSpec.TagReportContentSelector = reportContent;

取代它
