[Ember zigbee] prologue: protocol stack related documentation study notes

Original address: https://blog.csdn.net/tainjau/article/details/90648114

Write in front

• After thinking about it, I have been engaged in zigbee-related work for nearly a year. During the period, I always wanted to write something, but I didn’t know how to start. It happened to be the zigbee platform I was using. There are some documents on it. Thinking about it, or just take it as the starting point, just take a look at these documents seriously.
• The zigbee chip (Silicon Lab Ember Zigbee) I use here is currently updated to version 6.5 of its protocol stack. Although our company has not used the version 6.5 protocol stack yet, it is still provided by the version 6.5 protocol stack. Let's explain it in the document.

1. Source of materials

• Relevant materials and documents are extracted from the SDK. For the installation of SDK and development tools, please refer to the official website. Of course, there will be time later. I will also review the article on how to build a development environment. https://www.silabs.com/products/development-tools/software/simplicity-studio
• The document path is under the protocol stack folder of the SDK: \protocol\zigbee\documentation
• If you don’t want to download, you can go to this path and download the document directly: https://download.csdn.net/download/tainjau/11212921
