7. AT Command

7.1. AT command summary

AT command means, a user instruction set command is transmitted by UART module in command mode, explained later in detail using the AT command format. When
switching on to the configuration mode after power-on, the module can be set via the UART.
Switching from transparent transmission mode to command mode:
The UART device sends "+++" to the module continuously, after the module receives "+++", the module starts timeout after 3 seconds. If any AT command is received
within the timeout period, the module will successfully switch to the configuration mode. Before the mode was successfully switched, any UART data was transmitted
through the network.
Switching from command Mode to Transparent Transmission Mode
The serial device sends the command "AT+ EXAT" to the module. After receiving the instruction, the module returns "+OK" and switches to the transparent
transmission mode at the same time.
