(Note: all AT instructions need to be followed by a line break, except for the "++++" instruction, i.e., only the "++++"
instruction does not need to be followed by a line break)
In addition, users can use an external microcontroller (MCU) to communicate directly with the module UART for AT
command without using the backplane, enabling secondary development.
Hardware to be used.

Software that will be used (all can be downloaded from the official website)
1
Serial port debugging assistant AccessPort/XCOM
2
TCP&UDP test tool
3
SmartConfig (one-click configuration) mobile app "Wi-Fi Starter"
3.1 Traditional mode (NORMAL)
3.1.1 Link Preparation
First of all, users need to know that the module is restored to factory settings or default state network role as AP,
network mode as NORMAL mode, first, we need to connect the PC to the module to establish network connection.
①
. Connect the factory E103-W02 base board to the PC via Micro USB cable.
②
. Open the serial debugging assistant "AccessPort" and select the port number; if you don't know the port number,
please check it in the device manager (see the figure below).
③
. Set the serial port debugging parameters (Baud rate: 115200bps, data bit: 8bit, parity bit: no parity, stop bit: 1bit).
(See the figure below)
