如何通过 Beaglebone ZigBee 网关将传感器数据发布到 Bluemix

Question

我有三个运行 ZigBee（不是 BLE）的 TI CC2650 SensorTag，它们连接到运行 Zstack 网关的 Beaglebone Black。我希望将传感器数据发布到 Bluemix，但找不到配方。

我已经看到通过 BBB 网关连接到 Bluemix 的 BLE 传感器示例，就像这样

https://github.com/ibm-messaging/iot-beaglebone

但我找不到任何基于 ZigBee 的传感器。

我需要一些帮助来完成这项工作，因为我不确定我是否可以从头开始。

任何指导将不胜感激。是否可以使用这个 BLE 示例并对 json 代码进行一些编辑？

谢谢！ 约翰

请看一下： https://git.ti.com/zigbee-iot-agent/zigbee-iot-agent

这是一个节点 js 应用程序，它连接到 ZStack Linux 网关（在 BBB 上运行）并提供以下功能：

• 将 ZigBee 设备（灯、温度传感器、光传感器、开关）抽象为 JSON 对象。这已通过 Philips Hue Lights、TI ZLights (https://store.ti.com/cc2530zdk-zll-cc-debugger.aspx) 和 ZigBee 传感器标签（运行可从 BLE iOS 应用下载的 ZigBee 固件）进行测试。

• 提供一个网页，让您可以控制 ZigBee 网络和设备。

• 将设备数据转发到 QuickStart 服务，无需 Bluemix 帐户即可访问。

• Web 界面可用于供应设备，以便它们可以连接到供应的 Bluemix 服务。这是控制设备所必需的，但确实需要一个 Bluemix 帐户。

这是一个示例节点红色流程，用于根据传感器标签光传感器报告的发光度控制灯光级别：

您可以使用 python 的Requests framework，它可以通过 url 发布您的数据。 （REST 方法）您可以使用 post、get、put、delete 等。
