Off-grid and factory reset：
For modules that have been connected to the network, press and hold this button for 5 seconds until the status indicator is always
on, release the button, and the module exits the current network. When the module has been disconnected from the network, press and
hold this button for 5 seconds. When the status indicator is always on, restore the factory settings.
4.4.3 Status indicator: (It is recommended that this pin be connected to a low level to drive the LED)
This pin is usually high level, when the following events occur, it will output a continuously changing high and low level.
Node access status
：
The module is configured as routing, terminal node, and sleep terminal node. After the first network connection is successful,
this pin outputs a low level of 166ms 3 times, and the interval between the two low levels is 166ms.
With v1.1 firmware, the LED
flashes rapidly (10Hz strobe) during the node's distribution network. The strobe lasts for several seconds. If the LED stops flashing and
does not convert to 166ms slow flash, the node's distribution network fails.
The coordinator created the network successfully：
The coordinator successfully created the network for the first time, the pin outputs a low level of 166ms 3 times, and the interval
between the two low levels is 166ms.
network open state：
When the coordinator starts to distribute the network, or the network of the routing node is opened by the coordinator, this pin
outputs a low level of 500ms, and outputs a low level again every 500ms, until the network is closed (including manual closing and
automatic closing).
Identify Flag Status：
When the router or terminal node is marked by Identify, this pin outputs a low level for 500ms until the end of the Identify mark.
This function can be used to visually detect where the module with a certain MAC address or short address is located.
Precautions
：
The network open state and Identify flag state of the routing node, the output signal of this pin is the same, so in actual
operation, it should be avoided to perform both operations at the same time.
