When the node is a sleep terminal, its functions are as follows:
Sleep_time: (1～60) Sleep wake cycle is 1～6, unit (second)
(61～255) Sleep wake cycle is 60+(sleep_time-60)*10, unit (second)
Default value is 10, which means 10 seconds.
It represents sleep cycle, data request cycle and heartbeat cycle. When it is less than 30 seconds, the device can receive
the data from the parent node. The smaller the period, the smaller the delay of receiving data, the faster the speed of
switching the best parent node, and the faster the speed of detecting the lost parent node.
When the node is a sleep terminal, its functions are as follows:
If the node is a terminal, it represents the heartbeat cycle of the terminal and the parent node. The shorter the cycle is, the
faster the terminal switches the route to find the best parent node. At the same time, the coordinator detects the network
access of the terminal through heartbeat.

Note: if the node is coordinator and router, this parameter is invalid.
6.5.15 Save time of parent node
Time: the time for the parent node to save the data of its child node is 30 seconds. If the terminal node needs to receive
the data from the parent node, the configuration of sleep time cannot be greater than 30 seconds.
Note: this parameter is the parameter of the parent node (router and coordinator), which temporarily saves the data to be
sent to the sleep node. The parent node (router and coordinator) is E180-ZG120A/B device.
