7.1 AT command introduction

The AT instruction refers to the instruction set that the user passes the command through the UART and the module in the
command mode. After switching on to the configuration mode after power-on, the module can be set via UART.
Sequence from Transparent Transmission Mode to Instruction Mode:
The serial port device sends "+++" to the module continuously. After the module receives "+++", the 3s timer timeout starts.
If any AT command is received within the timeout period, it will switch to the configuration mode successfully. (Note: Before
the mode was successfully switched, any serial port data was transmitted through the network.
Sequence from AT command mode to network transparent transmission timing:
The serial device sends the instruction "AT+ EXAT" to the module. After receiving the instruction, the module returns
"+OK and switches to transparent mode at the same time.
Instructions: <CR>: ASCII code 0x0d;
<LF>: ASCII code 0x0a;
