4.6 Configuration
There are two configuration methods: serial port configuration and air configuration. The two configuration methods are basically the
same. Before the air configuration, the authentication password of AT+AUTH=123456 must be passed. After the authentication is
passed, the module is allowed to use the air configuration. The air configuration authentication cycle is this connection, and
re-authentication is required if the device is disconnected and reconnected.
The module is not connected by default in configuration mode, if the module is connected, you can enter the configuration mode by
sending "+++".
4.7 Data indication
When the module outputs data through the serial port, the module sets the DATA pin to low level, indicating that data is being
sent. AT command response does not change the DATA pin state.
