1Quick Start

WIFI232 series product is used to transmit data between RS232 and WIFI TCPIP

transparently, user can update the product to WIFI control without knowing the WIFI

and TCPIP detail. All the convert work is done by the module. For users, the RS232 side

is only as a serial device, the WIFI side is TCPIP Socket data. User can setup the work

detail by sample settings which can setup via inside web pages or RS232 port. The

setup work only need do once, then it will save the setting forever.

This chapter is a user guide for WIFI232 series products. We suggest users follow

the guide to test module at first, and will have a good understanding of the modules.

Users can also choose the chapter which you are interested in to read. For specific

details and instructions, please refer to the following chapters

1.1 Hardware connection

In order to test the communication between serial and WIFI network, we need to

connect the serial port to PC, and also connect WIFI network to PC. Due to the special

need both WIFI and serial, we connect and USB WIFI network Card as below, or you

could use laptop which has WIFI.

About the serial connection, because the module is 3.3V TTL level, the computer

cannot connect to it directly. Users need to use a TTL to RS232 adapter cable and then

connect to PC. In order to facilitate the test, we provide WIFI232 evaluation board for

users to choose.

1.2 Network Connection

The following is the WIFI232 module example. Open Wi-Fi, search network, as

shown in below, WIFI232 is the default network name (SSID) of the module.

Join the network, choose to automatically obtain IP, WIFI module supports DHCP

server and it is enabled by default.

Now, the Link led of WIFI232 Evaluation board is lighting.

1.3 Communication test

Default setting of module:

•SSID: WIFI232;

Figure 2 WIFI search

Figure 3 inquiry the address via DHCP

Server

WIFI232-B2 User Manual

7/ 102

•Encryption mode: open, none;

•UART: 57600, 8, 1, None;

•Network parameters: TCP, Sever, 8899, 10.10.100.254;

•IP: 10.10.100.254

We just need to follow the corresponding parameters to set the network

communication parameters. With the setting, we could make serial <-->WIFI

communication. The steps are as below:

1. Open the test software TCP232-test;

2. COM Setting area (left):

Choose COM port which has been used to connect the module, there is COM 10,

choose baud rate to 57600, it is the default baud rate of WIFI module. Then click Open.

3. Net Settings area (right);

Choose TCP client mode, Server IP write 10.10.100.2554. It is the WIFI default IP

address, Server port set 8899, it is the default listen Port of the WIFI module. Click

Connect to link to the module.

Now we could test send data between RS232 and WIFI.

COM port to WIFI: PC RS232->Module RS232->Module WIFI->PC WIFI.

2Overview

2.1 Description

WIFI232 module is an integration of 802.11 b/g/n Wi-Fi module, which provide a

wireless interface to any equipment with a Serial interface for data transfer. With this

module, traditional serial devices or MCU control device could connect to Wi-Fi

network easily,

The module used to MAC, baseband chip, RF transceiver unit, as well as the

power amplifier; Embedded firmware support wi-fi protocols and configuration, as well

as the network TCP/IP protocol stack.

WIFI232 uses the industry's highest performance embedded industrial structure,

and for the application of smart furniture, smart grid, handheld devices, personal

medical, industrial control, etc. These data fields, do a professional optimization.

WIFI232 as a hot spot can accommodate 32 clients simultaneously wi-fi access, but also

can accommodate 32 TCP client.
