4.4.2 Network function key function introduction

One key network function

：

Modules that have been configured as routing nodes, terminal nodes and dormant terminal nodes can be added to a coordinator

with a network turned on by pressing the network function key briefly (less than 1 second) and then releasing it without entering the

network or leaving the network.

If the module is configured as a coordinator, short press the network function key when the coordinator has not established a

network to directly create a new network, short press the key for the coordinator of an existing network to start the distribution

network, and short press the key for the coordinator of an existing network to close the network.

Automatic binding function：

Any two nodes that have been connected to the network, press this key successively (3 seconds interval, the status indicator of

the module to be pressed first flashes), automatically bind data transparent transmission; if you need to bind the control light or switch,

you can Let the light or switch enter the Identify state, and then short press the button on the module. After the binding is successful,

the module can control the light or switch through AT commands, and receive the status attribute report of the light and switch. When

binding lights or switches, you can set multiple lights or switches to enter the Identify state at one time, and the module can bind

multiple lights or switches at the same time with one keystroke. The coordinator does not support the automatic binding function.
