★GPIO2 is already been internal pulled up

★ In transparent-transmission on power-up mode, GPIO2 will indicate the status of module. The module has

connected a led to this pin. Users can get the status of the module by observing LED. Besides, you may connect GPIO2

to the external MCU.

★ LED indication when module works in power-on transparent transmission mode：

Intermittent double flash：cannot connect to AP access point.

Intermittent single flash：connect to AP access point, but cannot connect to TCP server.

Quench：connect to AP access point and TCP server.

4 Recommended connection diagrams

Note：supply voltage is 3.0V~3.6V. 500mA LDO is recommended for steady operation of module.

Chengdu Ebyte Electronic Technology Co., Ltd. E103-W01 User Manual

5 Package requirements

Note: Please try to use the package in the product package. When making the E103-W01 chip package, do not place

the pads under the non-functional pins！

6 Quick Start

E103-W01 module is easy to use. In order to allow users to quickly familiarize themselves with the module, this

section will guide the user through simple setup to achieve configuration and communication in various modes.

The test process uses AT commands. For quick connection, we have developed quick configuration software for users.

This section of the test uses the configuration software to operate, the module will echo the currently issued

instructions, so that users can quickly understand the usage of the AT command (Note: you need to add a line break

after each AT command).

Of course, after the user is familiar with the AT command, the AT command can be manually sent using the serial

debugging assistant without using the configuration software. It is also possible to use an external controller (MCU)

to directly connect to the module UART for AT command communication without using the backplane.

2

【Built TCP server】：

Open TCP&UDP test tool to build a TCP server: port6000 (configurable for user).

Click to start the server, then TCP server from PC starts to listen to port6000, and other network devices can

connect and communicate with it.

3

【Module installation】：

Substrates VCC short jumper, GPIO0 jumper disconnected.

Plug E103-W01 into test baseboard.

Plug the baseboard into PC by USB connector (Please download CP1202 driver if the PC cannot recognize

baseboard).

USB port number for testing：COM30.

AP mode is the default mode for E103-W01, which is equivalent to Wi-Fi router. Cellphone or PC can search

Chengdu Ebyte Electronic Technology Co., Ltd. E103-W01 User Manual

to the wi-fi name as EBT_XXXXXX (XXXXXX is last three-byte for MAC address).

If the MAC address for module is “1a:fe:34:ed:a6:68”， then SSID is “EBT_EDA668”.

No password for default.

4

【STATION mode configuration】：

Open Wi-Fi configuration software, select port number in the left corner, then the serial port open

automatically.

Serial port status changes to open now, click “STATION” button to enter configuration interface.

The test router name as Ebyte, password is e30e31e32.

Click “enter Sta mode” to change the mode to STATION.

Click “connect to router”, and wait a few seconds to see the interface shown in the figure below, which means

module is connected to the router successfully.

Then user can click “IP information query” to query IP information.

5

【TCP Client configuration】：

Click “Client configuration” to modify the remote port as 6000(corresponding to TCP server), and modify

server IP as 192.168.1.50（refer to PC IP）, then click “built connection” button.

See below figure：“CONNECT OK” means connection for TCP server is done.

At present server shows the connection is ok for device which IP address is 192.168.1.70(IP address is assigned

by router).
