如何连接到802.15.4帧流？

[英]how can I hook into a stream of 802.15.4 frames?

Using a packet sniffer I am able to detect and successfully read a "hello word" payload within an 802.15.4 frame . 使用数据包嗅探器，我能够检测并成功读取802.15.4帧内的“ hello word”有效载荷。

It's great can see the frames in the sniffer, but now I'm at the point where I would like to parse the payload out and do useful things with it. 可以看到嗅探器中的帧真是太棒了，但是现在我正要解析有效负载并用它做有用的事情。

I was wondering if the community could point me to sample C/C++/Java (or even labview, doesn't matter) code that uses hardware (like an xbee ) and can successfully parse out the payload in order to do useful operations. 我想知道社区是否可以指出我使用硬件（例如xbee ）并可以成功解析有效负载以进行有用操作的示例C / C ++ / Java代码（甚至是labview，也没关系）。

Is is possible to use the packet sniffer I already have for this purpose? 可以将我已经拥有的数据包嗅探器用于此目的吗？

I would greatly appreciate all / any advise. 我将不胜感激所有/任何建议。

EDIT: I have written a much better tool that does exactly this: https://github.com/andrewdodd/pyCCSniffer 编辑：我写了一个更好的工具，可以做到这一点： https : //github.com/andrewdodd/pyCCSniffer

If you are still interested there are a few tools that can help you receive the sniffed packets in a more friendly environment. 如果您仍然有兴趣，可以使用一些工具来帮助您在更友好的环境中接收嗅探到的数据包。

I "wrote" one such tool by combining 2 others that were available on GitHub. 我通过组合GitHub上可用的其他两个工具来“编写”这样一个工具。

NB: You have to be careful which version of firmware you have loaded on the sniffer, as TI change the format of the bytestream from time to time. 注意：由于TI会不时更改字节流的格式，因此您必须小心嗅探器上加载的固件版本。
