5. Communication Testing:
5.1 . Configuration for use the WF-01 as AP:
Step1: Power on the WF-01. (9~20V DC)
Step2: When the “Ready” light on, then use PC to connect to it via WIFI.
Noticed: if cannot see the SSID of the WF-01, please reset the device and try again.
Step3: Connect the WF-01 to PC via RS232/485 port, check the Com port, see the picture as below:
Noticed: if cannot see the com ports, then need to install the serial port driver.

Step4: When connect to the WF-01 successfully, the “Link” light will on, then “Open Network and Sharing
Center”, need to confirmed the IP and DNS is obtain automatically, see the picture as below:
Notice:If the the PC without Wireless LAN Adapter, then also can use the LAN cable to configuration.
Step5: Run the TCP/IP communication testing tool.
Notice:About the testing tool, please search it in the internet and download, lots of tool can do it.

This is the default setting, if need to changed, then can log in the WF-01.
>>> Open a Webpage, then login IP, default is 10.10.100.254;
>>> Default user name :admin Password :admin
>>> Then into the configuration page.
5.2 . Configuration for use the WF-01 as STA:
When WF-01 works in AP mode, we don't need access to the web for parameter setting, but in most
practical application, a serial port server WF-01 works as a STA, because data need to be uploaded to the
public network which is not available for AP mode. STA mode means the serial port server WF-01 to be
connected to the router or other AP. in this case, the server WF-01 is substantially equivalent to a wireless
network card. Detailed test steps are as follows:
Step1: After connecting to the WF-01:
>>> Open a Webpage, then login IP, default is 10.10.100.254;
>>> Default user name :admin Password :admin
>>> Then into the configuration page.

Step2: Click “mode selection” => select " STA "mode => click “Apply”, it will inform you to reboot the module, can
do it right now, also can do it later.
Step3: Click “STA Interface Setting" to search router, select the correct “SSID”, and “Apply”,then input
password and click “Apply”. Also can add 2 backup routers, when WF-01 fails to be connected in 1st router,
it will be change to connect to the another one automatically.

Step4: Open a New tap, log in the router, Mapped a port in router for received the data from WF-01.
>>> Then remember the port! (The port is very important!)
>>> Click “Application Setting”, must confirm the UART Setting is same as the UART Testing Tool setting.

How to know the router IP: Search it in the Google.
Step5: “Device Management”, >>> Restart >>> Apply.
Step6: Open the UART and TCP tool, choose the protocol type as "TCP Server ", that means the laptop
works as a Server, the serial port server WF-01 as a client. Then fill in the local host IP as the laptop’s IP
(This IP address is the local IP which mapped a port before).
Now, can start to testing! If it can send and received the data successfully, means it can working good!

6. Application Mode Explanation
6.1 APApplication: (Wireless remote controller application)
As shown below, when WF - 01 works as AP (access point), it creates a wireless network and works as
center node in this wireless network. Smart phones and other smart devices can remote control serial
devices via wifi. This AP mode brings great convenience when extra network is not available for smart
devices, just like a wifi router.
6.2 STA Application: (Remote connection application)
As shown below, when WF - 01 works as STA (station), it can be connected to the Internet through the
gateway. In this network construction, data from serial devices can be sent to Internet server for further
processing by WF - 01 , also the Internet server can also send commands to control the serial devices via
WF - 01.
8.Working Mode:
8.1 Data Transmission Modes
WF - 01 has three work modes: transparent transmission mode, serial instruction mode, HTTPD Client
mode. (Serial instruction mode and HTTPD mode need to contact the company's technical staff to
upgrade the software).

www.GPRS-M2M.com Tel:[phone] ext.803
8.2 Transparent transmission mode
In this mode, the data transmission between the server and network is transparent transmission.
Transparent transmission means the data length and content remain exactly the same between the sender
and receiver. The server does not do any analysis. Transparent transmission mode is the simplest way of
data transmission, because serial devices can realize wireless data transmission without make any software
change basically.
Noticed: transparent transmission mode, as the lower level of data transmission, does not guarantee
the zero error rates. Error rate can be cut down by adopting the upper TCP protocol handshake, or opening
hardware flow control (CTS/RTS) function in the serial port (if this function is not adopted, please vacant
CTS/RTS pin in the serial port).
8.3 Serial instruction mode
In this mode, the user can send data to the server through our protocol, the biggest advantage of this
mode is that there is no need to reset the module WF-01.
8.4 HTTPD Client mode
In this mode, the wifi-serial server of WF-01 sends request and data to the HTTP server. Every time to
send data, the wifi-serial server of WF-01 will automatically envelope the data into the HTTP protocol form,
then sent the enveloped data to the specified HTTP server. It is convenient for users read or submit data
from the HTTP server.
8.5 GPIO mode
WF-01 module can provide seven GPIO, including three indicator pin, 4 UART pin which can be
customized to GPIO pins. In GPIO mode, users can send a few specific instructions via the network to
control GPIO to ourput a high/low level and can also read the GPIO status.
9. Device reset
When WF - 01 in the STA mode, it will always automatically connect to the router or other AP once
powered on, if you want the device back to initialization stage, please long press the reset button for 5
seconds, the Ready LED and Link LED will be off. When the device powered on again, it will recovery to
default status.
10. Function Expansion
10.1 Keep Alive Function
When something abnormal happens to the network, WF-01 will automatically dignose connection
problem and switch to other networks. When network signal is weak, WF-01 working as a STA will also
switch to other networks. With the switching , WF-01 restart.

10.2 Web Socket Function
The WIFI serial port server can realize the function of the web socket server. It makes real-time
communication possible between serial port server and the webpage, replacing previous HTTP GET, POST
which response slow.
Noticed: This function is fit for network applications and other application highly demanding quick web
page response. If users want to customize the specific web page, please contact our company directly .
10.3 Hardware Upgrading
WIFI serial port server WF-01 Support firmware upgrade remotely through web.
11. Frequently Asked Questions
Question 1：Where to set the LAN IP and WAN IP of WF-01？
>>> Please set LAN IP in the "wireless access point Settings" page, as following:
>>> Please set WAN IP in the "wireless terminal Settings" page, as following:
Question 2：When using WF-01, how to avoid an IP address conflict?
>>> The dynamic distribution IP address is .100--.200. For example, when the LAN address of WF-01 is
10.10.100.254, the dynamic distribution IP address of its STA is 10.10.100.100 to 10.10.100.200. While
its Static distribution IP address is from 10.10.100.1 to 10.10.100.99, to avoid conflict between
dynamic IP address and static IP address.
Question 3: what is the difference between TCP and UDP protocol?

www.GPRS-M2M.com Tel:[phone] ext.803
>>> TCP is a protocol based on connection, that is, before formal data sending /receiving, a reliable
connection must be established between two sides. UDP is not based on connection, that is the two
sides directly send/receive data without establish any connection first. TCP is fit for applications where
demand high accurate data transmission, such as web page browsing, files downloading. UDP is fit for
applications where allow a small amount of data transmission or low accurate data transmission, such
as QQ voice/video data.d
