4. Operating mode
4.1 Transmission mode
When the module enters the transmission mode, any data received by the serial port will be sent out wirelessly. The
transmission mode is wireless communication between network nodes. The communication methods include unicast,
protocol unicast, multicast, protocol multicast, and broadcast. and so on.
4.2 Configuration Mode
When the module enters the configuration mode, the data received by the serial port defaults to the configuration
command to configure and operate the device. In the configuration mode, the data received by the serial port of the
module is regarded as a HEX command.
4.3 Mode switch
4.3.1 Command switching
The module power-on initialization defaults to the transmission mode.
In the transmission mode, when the module serial port receives the "2A 2D 2E" character, it will enter the configuration
mode. After entering the configuration mode, it will return the "7A 7D 7E" character. In the configuration mode, when
the module serial port receives the "2F 2C 2B" character, the module exits the configuration mode and enters the
transmission mode. After entering the transmission mode, it returns the "7F 7C 7B" character.
4.3.2 Pin switching
Working mode switch pin PIO2, internal configuration pull-up resistor input mode, power-on default high level, in any
mode when the mode switch pin PD4 is pulled down for more than 100ms, the module work mode switch. Switch to
configuration mode by pin, serial port will return to "7A 7D 7E" character; switch to transmission mode via pin, serial
port will return to "7F 7C 7B". The details are shown in the figure below:
