3. Quick Start
The E103-W05 module is simple, easy to use, and easy to access the network. It is compatible with most AT
commands of E103-W01 so that it can use E103-W01 controller to easily set the parameters of E103-W05. Users can
refer to several working modes of the module to use the module: module to module, module to server, module to client.
When configuring the parameters of the module, the user first needs to ensure that the operating voltage of the
module is 3.0~3.6V (typical value is 3.3V), and then confirm that the serial port pins have been correctly connected with
the relevant serial port tools and can communicate normally.

1. The user searches the hot spot of the E103-W05 module through the computer and connects to it.
2. The user establishes a TCP Client on the PC and connects to the listening port of the module TCP Server to achieve
communication.
3.2.2 Network model
3.2.3 Setting
A. Open the E103-W01 configuration software, select the serial port number(1) and baud rate(2) (default 115200), query
the version information(3), and check whether the receiving box(4) has version-related data. If there is, it means that the
communication is normal. As shown below:

F. We establish a client on the PC and connect the client of the module, and then can send data. Here, if the server needs
to send data to the client, it can be sent by the AT+CIPSEND instruction. Here users can download the AT instruction
manual of E103-W05 in the data download.
3.3 Steps for Module to work in STA mode as TCP Client.
3.3.1 Brief Introduction
We use the E103-W05 module as the STA working mode to search for nearby WIFI and connect it. At the same time, the
computer is also connected to the same WIFI, so that the E103-W05 and the computer are in the same local area network.
Create a TCP Client on the module side and create on the computer side TCP server, and then communicate.

3.3.3 Setting
A. Set the module to STA mode and connect to the relevant WIFI hotspot (router). When the connection is successful,
the following information is received in the data box. At this time, we can query the assigned IP information through IP
information query.
B. Connect our computer to the same wifi as the module and keep them in a local area network.

E.After successfully connecting to the server, we can communicate data between the server and the client, but here, in
order to achieve simple transparent transmission of data, we also need to make some settings to enter the transparent
transmission mode, so that we can avoid specifying each time you send data Awkward operation of width. After the
client connects to the server, perform the following operations to enter transparent transmission.
⑥. Transparent Data Transceiving.

4. Notice
4.1 Relation of AP，STA and Server Client
In the process of two network access examples in 3.2 and 3.3 above, it is not only in AP mode that users can establish
TCP Server. Similarly, it is not only when the module is in the STA mode that the user can establish a TCP Client. AP
and STA are just a working mode for the module to access the network. TCP Server, TCP Client and UDP can create the
network chain in any mode of the module.
4.2 Transparent Transmission
The transparent transmission mode can be used only when the module works in TCP Client and UDP. The TCP Server
cannot enter the transparent transmission mode. After entering the transparent transmission mode, you must remember to
manually use AT+CIPSEND to activate the transparent transmission. For transparent transmission, you need to make
relevant settings in the following interface;
4.3 Maximum number of AP connections and server connections
When setting up TCP Server and TCP Client, pay attention to the options of opening and closing multiple connections;
When the module is used as an AP, it can be connected by at most 5 STAs. When the module works in TCP Server mode,
it can be connected by at most 5 TCP Clients. Therefore, customers are recommended to use it when performing short
packet data or not considering packet loss. UDP performs related communications.
