System Configuration
<AP> IEEE 802.11b/g/n Compatible
<WizFi210> Serial to WiFi Module
<PC 1> is connected to AP through wireless or wired network. In the <PC 1>, TCP Client is
installed.
<PC 2> is connected to WizFi210 through serial. Serial program is installed in this <PC 2>
This document describes how to test “Serial to WiFi” of WizFi210. As shown in above figure,
WizFi210 will transmit the serial data received from <PC 2> to the TCP Client of <PC 1>
through wireless network.
In this testing, the AP is supporting 802.11 b/g, and using WPA Personal/TKIP security method.
WizFi210 is configured as fixed IP address and TCP/Server mode.
PC1 can communicate with WizFi210 using TCP Client program, and PC2 is connected to
WizFi210 through serial terminal.

1. AP Configuration
The wireless configuration of AP(Model : Linksys WRT54G2) is as below.
- SSID : WizFiDemoAP
- Channel : 6
- Security : WPA Personal/TKIP
- WPA Shared Key : 12345678

2. Connecting <PC 1> and AP
Check the IP address of the <PC 1>.
If the <PC 1> is connected to AP through wireless network, check the IP address of the wireless
adaptor. If it is connected through wired cable, check the IP address of the wired network
adaptor.
Below is showing the IP address of the PC is configured as ‘192.168.3.199’

3. Connecting <PC 2> and WizFi210
Connect the <PC 2> and WizFi210 using serial cable and supply the power. You can see
following message in the serial terminal program. Depending on the version of firmware, the
following message may not be available.
Configure the serial port of the <PC 2> as (115200bps, 8 bit, none parity, 1 stop bit)
At the serial terminal program, if you input “AT” and <ENTER>, you can see the “OK” message.
When “OK” message is displayed, WizFi210 enters into AT command mode in which AT
command set can be used. If “OK” message is not displayed, check if there is any problem in
power supply or serial cable, and try again.

4. Using WizFi210 at the AT Command mode
(1) AT+WWPA=12345678
This command sets WPA Passphrase as “12345678”
(2) AT+NDHCP=0
This command sets WizFi210 as using fixed IP address (not DHCP). When the IP address is
acquired by DHCP, the command “AT+NDHCP=1” is used.
(3) AT+NSET=192.168.3.123,255.255.255.0,192.168.3.1
This command sets the module with IP address (192.168.3.123), Subnet Mast (255.255.255.0),
and Gateway Address (192.168.3.1).
(4) AT+WAUTO=0,WizFiDemoAP,,6
This command sets the AP’s Mode (0:Infrastructure), SSID(“WizFiDemoAP”), BSSID(Default)
and Channel Number (6)
(5) AT+NAUTO=1,1,,8011
This command sets WizFi210 with Server(1), TCP(1) and Port number (8011).
Destination IP address is not required.
(<Type>,<Protocol>,<Destination IP>,<Destination Port>)

(6) ATA
This command initializes auto connection. If you input the command, WizFi210 initializes auto
connection by using the parameters configured by AT+WAUTO and AT+NAUTO.
When the connection is successfully established, WizFi210 returns “OK” with IP address,
Subnet Mask and Gateway address. If the connection is failed, “ERROR” is returned. After
connection is established, WizFi210 enters into data communication mode.
If WizFi210 is already connected to wireless network, you can use the ATA2 commands. ATA
commands start from AP Association, but ATA2 commands start from auto connection using
already connected APAssociation.

5. Data Communication Test
(1) <ATA> command returns “OK”.
(2) Connect <WizFi210> to the TCP Client program of <PC 1>.
(3) Input characters at the <PC 1> and send them to the network.
(4) Input characters at the <PC 2> and send them to the serial.
(5)Close the connection with WizFi210 by finishing the TCP Client program of <PC 1>.
<PC2> Serial Terminal Program <PC1> TCP Client Program
Input characters. This data is from <PC 1>.
Input characters. This data is from <PC 2>.
