There are two kinds of timeout: one is the timeout of application layer event, the other is the timeout of MAC layer
event.
1) Timeout of application layer, can be obtained through osal_next_timeout() of osal_pwrmgr_powerconserve(void)
function;
2) Timeout of MAC layer, can be obtained through MAC_PwrNextTimeout() of halSleep(uint16 osal_timeout)
function.
⑥ What new features does ZigBee 3.0 stack have?
Please refer to below link, it describes the new features of the ZigBee 3.0 stack as compared with the previous
ZigBee Home Automation/ZigBee Light Link.

⑦ About the difference between OAD and OTA in TI protocol stack?
OAD is short for Over the Air Download, OTA is short for Over the Air. The functions of these two are the same,
they can be called the software upgrade on air. In the earlier ZigBee protocol standard, there was no standard for node
software upgrading on air, but many customers have such requirements, thus TI developed their own protocol stack for
software upgrading on air, and named it as OAD. After that, ZigBee alliance noticed the more and more requirements for
upgrading on air, so they developed the upgrading on air standard and named it as OTA, this standard has taken the TI
OAD method as reference and has made some modification. The upgrading on air in TI's earlier protocol stack, it is
called OAD, and in the later stack, it is called OTA as following the ZigBee alliance stack.
⑧ Which protocol stack shall be selected for developing private application based on ZigBee Mesh?
Many customers only need to apply the function of ZigBee Mesh network in their system or products, and do not
need to do according to the application layer as defined by the ZigBee, especially for some industrial applications, as for
such requirements, how to select proper TI protocol stack for developing products?

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 that between the recommended supply voltage, if exceeding the maximum,
