default baud rate to 115200.
Serial port receive wakeup: support the serial port receive wakeup function, when the module is in sleep state when it
receives a frame of less than or equal to 10 bytes of data, it will be awakened. This data is a wake-up frame used to wake
up the module and will not be treated as data .
Module reset: The user can reset the module through the serial port command.
Restore factory settings: the user can restore the factory settings of the module through serial commands
Over-the-air configuration: users can use over-the-air configuration commands to remotely configure other devices in the
network
1.3 Device Types
There are four types of logical devices in the ZigBee network: Coordinator, Router, End-Device (non-sleeping terminal) and
Sleep-End-Device (sleeping terminal). The ZigBee network consists of a Coordinator, multiple Routers, and multiple
End_Devices (the terminal nodes can be divided into dormant terminals and non-dormant terminals). This product only supports
End-Device (non-sleeping terminal) and Sleep- End-Device (sleeping terminal) two device types, Coordinator (coordinator) and
Router (router) two types use our E180-ZG120A/B products .
1.3.1 Non-sleeping terminal
The main task of non-sleeping terminal equipment is to send and receive messages, and other nodes are not allowed to
connect with the terminal equipment. The non-sleeping terminal is always in the working state and can receive and send data at
any time.
1.3.2 Sleeping terminal
The dormant terminal enters a dormant state when there is no data transmission and reception, and the dormant current is as low
as about 2uA.
When you need to send wireless data or perform command operations, you need to send a wake-up frame through the serial port.
The length needs to be 5 bytes (it is recommended to use "FF FF FF FF FF" to wake up with 5 bytes of "FF"). Time, the serial port
data (configuration commands, payload) can be processed during the period. When a frame of serial port data is successfully received,
the wake-up timeout counter will be refreshed, and the wake-up duration will go back by Uart_holdtime, otherwise the device will go
to sleep again. Uart_holdtime defaults to 1000ms and supports HEX command to change its value.
Sleep terminal wake-up can also be awakened through the function pin WAKE. WAKE defaults to high level. Pull down the
WAKE pin and the module continues to wake up. Release the WAKE pin to restore the default high level and the module resumes
sleep.
When data needs to be received, data is received through periodic wake-up. The longer the wake-up period is set, the longer the
reception will be. The wake-up period must be less than 30 seconds. If you only need to upload data, you can set the wake-up period to
be greater than 30 seconds or longer to reduce power consumption (the default is 10 seconds) such as battery-powered sensors.
