What's new in the ZigBee 3.0 protocol stack?
Please refer to the link below for an introduction to the ZigBee 3.0 stack compared to the previous ZigBee
Home Automation/ZigBee Light Link.

About the difference between OAD and OTA in the TI protocol stack
OAD is short for Over the Air Download, OTA is short for Over the Air. These two implementations have the
same function, which is an aerial upgrade of the program. In the early ZigBee protocol standard, there was no
standard for node program air upgrades, but many customers had requirements for air upgrades, so TI
developed a protocol stack for program air upgrades and named it OAD. Later, the ZigBee Alliance saw more
and more demand for air upgrades. It also specified the standard for air upgrades. It was named OTA. The
standard also referred to TI's OAD implementation and made related changes. Therefore, in TI's early protocol
stack, the air upgrade was called OAD, and the subsequent protocol stack followed the ZigBee Alliance's air
upgrade protocol, called OTA.
If you develop a private application based on the ZigBee Mesh network, which protocol stack should
you choose?
Many users only want to use the functions of the zigbee mesh network in their own systems or products. They
do not need to be completely in accordance with the application layer specifications defined by zigbee,
especially some industry applications. For such application needs, how should I choose TI's appropriate
protocol stack for product development?

6 Basic operation
6.1 Hardware design
It is recommended to use a DC stabilized power supply. The power supply ripple factor is as small as
possible, and the module needs to be reliably grounded.;
Please pay attention to the correct connection of the positive and negative poles of the power supply.
Reverse connection may cause permanent damage to the module;
Please check the power supply to ensure it is within the recommended voltage otherwise when it exceeds
the maximum value the module will be permanently damaged;
Please check the stability of the power supply, the voltage can not be fluctuated frequently;
When designing the power supply circuit for the module, it is often recommended to reserve more than
30% of the margin, so the whole machine is beneficial for long-term stable operation.;
The module should be as far away as possible from the power supply, transformers, high-frequency wiring
and other parts with large electromagnetic interference.;
High-frequency digital routing, high-frequency analog routing, and power routing must be avoided under
the module. If it is necessary to pass through the module, assume that the module is soldered to the Top
