The default value of the parameter is 10, which means 10 seconds.
It indicates the sleep period, and also indicates the data request period, and also indicates the heartbeat period. Less than
30 seconds can receive the data sent by the parent node. The shorter the period, the smaller the delay in receiving data;
the shorter the period, the faster the optimal parent node switching speed, and the detection The faster the parent node is
lost.
When the node is a terminal, the functions are as follows:
If the node is a terminal, this parameter represents the heartbeat cycle of the terminal and the parent node. The faster the
heartbeat cycle, the faster the terminal switches the route to find the best parent node, and at the same time, the heartbeat
is used to detect the online status of the parent node.
Note: If the node is a coordinator and a router, this parameter is invalid;
6.5.15 Parent node save time
time: The parent node saves the data of its child nodes for 30 seconds. If a terminal node needs to receive the parent node
data, the sleep time configuration cannot be greater than 30 seconds
Note: This parameter is the parameter of the parent node (router and coordinator), and temporarily saves the data
buffered and sent to the sleeping node.

The default value of the parameter is 5, which means 5 seconds.
When the node is powered on, it will join the network (if there is no network status) or restore the network (if there is no
network status) or resume the network (if there is no parent node status). When the node is running, it will rejoin the
network after the parent node is offline. even.
