Note：supply voltage must be 2.4V~3.6V, 500mA LDO is recommended for steady operation
of module
3.Quick start
E103-W02 module has the following 5 modes:
Mode
Description
NORMAL
In this mode, there is no difference from the function of V2.0, that is, it supports
1-channel TCP server or 1-channel TCP Client or 1-channel UDP, and supports
remote AT command function.
MQTT
In this mode, it supports the general MQTT client function, and supports 1-
channel subscription topic and 1-channel report topic at the same time.
HTTP
In this mode, it supports general HTTP client, and POST and GET request
methods.
MULTIS
In this mode, it supports multiple TCP links. As a TCPSERVER, the module
can allow 4 TCPclients to access simultaneously.
MULTIC
In this mode, it supports multiple TCP / UDP links. As a TCP / UDP client, the
module can access three servers simultaneously.
E103-W02 module is easy to use. In order to allow users to quickly familiarize with the module,
the following guides users to quickly use the module for different modes, and to configure and
communicate in various modes through simple settings.
All the commands are used during testing are AT commands. We developed HTTP web page for
users to access the module and conduct quick configuration.
The tests in this chapter are conducted with Serial debugging assistant, the module will return the
current commands so that users could quickly learn the way to use AT commands. (Notes: All AT
commands shall be followed with a line break except for “+++” commands)
•In addition, users could use external MCU instead of baseboard to connect the UART of the module
for AT commands communication to realize secondary development.

3.1 Traditional mode(NORMAL)
3.1.1 Link preparation
First of all, you need to know that when the module is restored to factory settings or the default
status, the network role is AP, and the network mode is NORMAL mode. First, we need to connect the
PC to the module to establish a network connection.
①. Connect the factory-made E103-W02 baseboard to the PC through the Micro USB data cable.
②. Open the serial port debugging assistant "AccessPort" and select the port number; if you don't
know the port number, please check in the device manager (see the picture below)
③Set the serial port debugging parameters (baudrate: 115200bps, data bit: 8bit, paritybit: no parity,
stop bit: 1bit).(See the picture below)
④. We open the wireless network on the PC, find the wireless network with SSID beginning with
"EBT" (such as: EBT_9BB311), and click on "Next" to connect. ("9BB311" here is the last 6 digits of
the module MAC address. The MAC address of different modules is different, so the SSID of different
modules is also different.)

⑤. After the connection is successful, the LED1 light on the module baseboard is always on (GPIO9
is pulled low), and the PC shows that the connection is successful, otherwise please repeat the above
steps.
3.1.2 Set the module as AP to establishes TCP SERVER and PC wireless connection
①. Open the TCP & UDP testing tool, create a connection, and set the parameters (see the figure below).
(The parameter value can be sent through the serial debugging assistant to send the corresponding AT
command for query and then exit the AT command mode to realize the subsequent two-way
communication between the PC and the module)

12
②. Click on the "Create" button to complete the creation, and then click on the "Connect" button.
③The LED 2 on the module baseboard is always on (GPIO10 is pulled low), indicating that the
connection is completed,then the PC and the module can communicate with each other mutually (it means
TCP & UDP testing tool and AccessPort can communicate with each other mutually), if not, please repeat
above steps.

④. It can transmit documents (better in TXT format), just have a try.
3.1.3 Set the module as AP to establish a UDP server wireless connection with a PC
Now let’s try to set up UDP communication, which needs some simple configuration on the module.
①. Make sure the link preparation is completed successfully.
②Enter AT command mode for simple configuration. (Please make sure to complete the
operation of No. 1 first. Since it is sending commands, please turn off the Real Time Send function of
the port in order to configure the module, if there is no Real Time Send function in your AccessPort,
please ignore this notice)
a. Start to configure the port, input command “+++”in the sending textbox (please do not add line
break), and click on Send button to start sending command.
b. If the port returns “Entered AT mode”, it means the module has entered AT command mode, if
not, please repeat the above steps.
④. By step ④, we have entered AT command mode, now let‘s start to configure Socket protocol.
a. Input“AT+SOCK=UDP,SERVER,192.168.1.2,8887,8889”in the sending textbox (please add
line break, which means to press Enter after “AT+SOCK=UDP,SERVER,192.168.1.2,8887,8889”),
click on Send button to start sending.
b. If the port returns “Socket update OK”, it means the command has successfully set the
protocol parameters, if not, please repeat the above steps.
④. Reset the module or restart when power off after setting parameters to validate the settings; If
there are still other parameters to set, please complete the setting before reset or repower. Because we
only configure Socket protocol, so just directly reset or repower (GPT010 is pulled low), the LED2 will
be lit up on the baseboard, it means the UDP protocol is available.
