Short-circuit the CONFIG terminal to the ground wire (GND terminal), and then turn on the power. At this time, the module enters the configuration state. In this state, the configuration of the module is as follows:
The address code is 00H
Baud rate 9600 bps
Prohibit checksum
ASCII character communication protocol
At this time, you can modify the module's baud rate, checksum status and other parameters through the configuration command, and you can also select the communication protocol by setting the module's communication protocol command. When you are not sure about the specific configuration of a certain module, you can also install a configuration jumper on the CONFIG terminal, and then reconfigure the module when the module enters the configuration state.
