我正在使用Motorola Scanner SDK和Motorola DS9808-SR rfid阅读器测试CS8300 RFID tag。
基本上，所有简单任务都有效：让扫描器发出蜂鸣声，通过属性35001获取epcID等;的除了：
在通过属性 35002 指定标签ID后，我始终从属性35009获取状态2（表示未找到标签＆＃39;）。注意：Attribute Explained in this doc
正如您在我的代码中看到的那样（第80行＆＃39;属性 35002 设置＆＃39;），我尝试了许多不同格式的epcID，例如 0080B0403C0000000C015F85 或 0x00 0x0e 0x08 0x80 0x00 0x80 0xb0 0x40 0x3c 0x00 0x00 0x00 0x0c 0x01 0x5f 0x85 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 ， 但都没有用。
我错过了什么？顺便说一下，我已经测试了几个BAP标签。标签本身很好，因为它们可以被其他读者/ SDK读取。

答案 0 :(得分：0)
数组类型属性应该是空格分隔的十六进制缓冲区的问题。
因此35002格式应为0x00 0x0e 0x08 0x80 0x00 0x80 0xb0 0x40 0x3c 0x00 0x00 0x00 0x0c 0x01 0x5f 0x85 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00。
请告诉我设置属性号35008的原因是什么？
