sleep_time： (1~60) Sleep wake-up cycle means 1~60 units (seconds)
(61～255) sleep wake-up cycle means 60+(sleep_time-60)*10 unit (seconds)
The default value of the parameter is 10, which means 10 seconds.
Indicates the dormant period, and also indicates the data request period, and also indicates the heartbeat period. The data sent by the
parent node can be received in less than 30 seconds. The shorter the period, the smaller the delay in receiving data; the shorter the
period, the faster the switching to the best parent node, and the detection It is also faster to lose a parent node.
When the node is a terminal, the function is as follows:
If the node is a terminal, this parameter indicates the heartbeat period of the terminal and the parent node. The faster the heartbeat
period, the faster the terminal switches routes to find the best parent node, and at the same time coordinates to detect the online status
of the terminal through the heartbeat;

Note: If the node is a coordinator and a router, this parameter is invalid;
6.6.15 Parent node save time
time：The parent node saves the data of its child nodes for 30 seconds. If there is a terminal node that needs to receive the data of the
parent node, the sleep time configuration cannot be greater than 30 seconds.
Note: This parameter is the parameter of the parent node (router and coordinator), which temporarily saves the buffered data sent to
the dormant node. The parent node (router and coordinator) is the E180-Z8910SX/P product
