我遵循以下教程：http ://www.pubnub.com/blog/pubnub-streaming-texas-instruments-iot/ 一步一步地编译和编码并连接到我的 Wi-Fi 接入点。我想我设法连接到 PubNub（代码打印在终端屏幕“PubNub 设置”上，但在代码中没有真正验证它确实已设置。

我在 PubNub 上开设了一个帐户，并将我的频道命名为“testing”（我在上传的代码中将其命名为相同 - 我检查了一百万次），当我转到开发控制台并单击订阅时，我看不到任何事物！我的意思是我可以通过开发控制台发布消息，但我真正想看到的是来自 CC3100 的消息。我检查了计算机上的 UART 终端，我看到数据不断打印，所以我知道它正在工作。我一遍又一遍地阅读教程，我正在做同样的事情，但它不起作用。任何帮助，将不胜感激！

我错过了什么？

谢谢

首先验证您的 PubNub 帐户是否已正确配置并且您的本地 Wi-Fi 连接是否正常 - 您是否能够在一个浏览器中从开发控制台发布消息并在另一个浏览器的开发控制台中接收它们？（当然，两者都使用相同的频道名称）。如果可行，请向帮助 (at) pubnub (dot) com 发送消息，提供您的子密钥信息和有关您的项目的信息，我们将尽力帮助您追踪问题。

这个答案发布得很晚。我承认我忘记了这篇文章，所以我决定更新它（虽然晚了几年）。

我开始挖掘以尝试查看问题所在，我想我找到了。首先，我看到 PubNub.publish() 不能与 json_String 一起正常工作，因为 json_String 是 90% 的乱码。所以我删除了大部分构建 json_String 的代码（插入模拟值的部分）并使其更简单。然后我还在最后添加了一部分代码，这是客户端变量的正确性能所需的，我从使用 CC3100 的基于 arduino 的项目中使用的一部分代码中得到了这些代码。

无论如何，新代码是下面的代码，现在它可以正常工作了！我终于看到了 PubNub 上的所有输入流！非常感谢！:D

/*PubNub sample JSON-parsing client with WiFi support
 
  This combines two sketches: the PubNubJson example of PubNub library
  and the WifiWebClientRepeating example of the WiFi library.
 
  This sample client will properly parse JSON-encoded PubNub subscription
  replies using the aJson library. It will send a simple message, then
  properly parsing and inspecting a subscription message received back.
 
  This is achieved by integration with the aJson library. You will need
  a version featuring Wiring Stream integration, that can be found
  at http://github.com/pasky/aJson as of 2013-05-30.
 
  Please refer to the PubNubJson example description for some important
  notes, especially regarding memory saving on Arduino Uno/Duemilanove.
  You can also save some RAM by not using WiFi password protection.
