Here are some frequent questions and answers about ZigBee products based on Texas instruments, which are summaried by RF-star - a leading wireless IoT suppiler. 1. Due to the differences among the versions of TI ZigBee protocol stack, how to choose the right protocol stack for development? TI ZigBee protocol stack Z-Stack is developed from Z-Stack 0.1 to Z-Stack 2.5.1a, and later Z-Stack Home 1.2.1, Z-Stack Lighting 1.0.2, Z-Stack Energy 1.0. 1, Z-Stack Mesh 1.0.0. In the process of upgrading the protocol stack, TI has mainly done two aspects of the protocol stack. 1) Add some new features according to the ZigBee Specification of the ZigBee Alliance. For example, ZigBee 2007 is a tree-shaped routing. In ZigBee Pro, Mesh routing is coming out, and routing algorithms such as MTO and Source Routing are proposed. TI adds corresponding new features to the protocol stack is to fix some related bugs in specs, such as those with ambiguous descriptions. 2) To fix the bug in the TI ZigBee protocol stack itself. The difference of the protocol stack between a version and the previous version can be found in the Release Note. After the version of Z-Stack 2.5.1a, TI protocol stack did not continue to be released directly in the form of Z-Stack 2.6.x, but was released in the form of Application Profile. The reason is that TI wants developers to choose more targeted protocol stack for development according to the actual application. Protocol stack like Z-stack Home 1.2.1 mainly includes the following two parts. 1) The Core Stack, the beginning of this part is the continuation version of Z-Stack 2.5.1a and later, can be found in the Z-Stack Core Release Notes.txt, Version 2.6.2. 2) The application protocol stack is related to the profile, which is mainly related to the actual application. The Home Automation protocol stack is all related to the implementation of the ZigBee Home Automation Profile. Similarly, Z-Stack Lighting 1.0.2 and Z-Stack Energy 1.0.1 are also a Core Stack with an application profile. a.Z-Stack Home 1.2.2a is developed for smart home related products. b.Z-Stack Lighting 1.0.2 is developed for ZLL related products. c.Z-Stack Energy 1.0.1 is developed for smart energy, Meter, In Home Display, and other related products. d.Z-Stack Mesh 1.0.0 is developed for products related to private applications, which only uses standard ZigBee protocol related features, such as Mesh routing, etc. The application layer is defined by the developer. After the ZigBee Alliance released the ZigBee 3.0 protocol, the latest ZigBee protocol stack is Z-Stack 3.0, which currently supports CC2530, CC2538, CC2652R, CC265P. 2. How to make ZigBee testing and certification? There is an example about the development of standard ZigBee Home Automation related products. To begin with, when developers develop products, they must develop products according to the products described in the ZigBee Home Automation Profile Specification which can be downloaded at www.zigbee.org.
