Question

我正在尝试使用zigbee协议，在VANET中建立两辆车之间的通信，作为车辆间通信的一部分。因此，我对此非常陌生，我想知道：

一个。我是否必须对我的Zigbee界面进行编程以建立通信？湾是否可以编写zigbee接口？ C。谁能让我大致了解如何在两个zigbees之间建立（使用编程语言）通信。？

任何帮助都将不胜感激。

Answer 1

一个。要建立连接并进行简单的发送/接收数据（在2个接口/模块之间），您不需要对ZigBee接口进行编程（例如XBee）。只需使用XCTU配置它们即可。但是，如果你想让它们按照你喜欢的方式相互沟通（用你自己的规则），你必须对它们进行编程。

湾如果你有XBee模块，那么你可以使用基于Java的xbee-api。对于其他模块，请查看模块的文档。

℃。此示例取自xbee-api网页（示例代码），该网页使用Java编程语言。这段代码所做的就是搜索附近的所有模块（节点发现）：
