★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 diagram
Note：supply voltage is 3.0V~3.6V. 300mA LDO is recommended for steady operation of module.
5 Quick Start
E103-W01-IPX 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.

【Transparent transmission】：
After the configuration, module can transmit data to TCP server directly without AT protocol.
Configuration： click “enter transparent transmission mode”(AT+CIPMODE=1) after connected to server,
then input AT+CIPSEND to enter transparent transmission mode.
Notes: module no longer receive AT command, transmit the data from UART to server directly.
If user continue to transmit data AT+CIPSEND, module will treat AT+CIPSEND as data and transmit it to
TCP server directly.
Data sent by server is also output directly from the module.

【Transparent transmission on power-up】：
Advantage: save the complicated operation steps for user, once the configuration for transparent transmission
on power-up is done, transparent transmission can be achieved on power-up.
After using this function, user only need to configure the connection between router and TCP once.
When module re-start or re-power, it will connect with router automatically, then connect with specified TCP
server automatically. User only need to wait the completion of TCP connection (wi-fi indicator goes out), then
transmit data directly.
Click “transparent transmission on power-up” and input corresponding wi-fi name and password, then click
“wi-fi”, see below interface means configuration is down.
