【英文标题】：use Motorola scanner SDK with DS9808-SR rfid reader: Always receive "tag not found" from attribute 35009

【问题描述】：

我正在使用 Motorola Scanner SDK 和 Motorola DS9808-SR rfid reader 测试CS8300 RFID tag。

基本上，所有简单的任务都可以工作：让扫描仪发出哔哔声，通过属性 35001 获取 epcID 等； 除了：

在通过属性 35002 指定标签 ID 后，我总是从属性 35009 获得状态 2（这意味着“未找到标签”）。注：Attribute Explained in this doc

正如您在我的代码中看到的（大约第 80 行“属性 35002 设置”），我尝试了许多不同格式的 epcID，例如 0080B0403C0000000C015F85 或 0x00 0x0 0x00 0x80 0xb0 0x40 0x3c 0x00 0x00 0x00 0x0x85 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 em>， 但没有一个工作。

我错过了什么？顺便说一句，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阅读器/SDK 读取。

我的代码：

【参考方案1】：

数组类型属性应该是空格分隔的十六进制缓冲区。

所以35002 应该格式化为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。

你能告诉我设置属性号35008的原因是什么吗？

【讨论】：

感谢您的快速回复。 1.“分隔的十六进制缓冲区”格式正是我尝试过的选项之一。 2. 35008 值为 1 表示 READ。 xml 代码来自本文档的第 5 页：goo.gl/crcnlG
