2. FUNCTIONAL DESCRIPTION
2.1. Wireless Networking
HF-LPT130A module can be configured as both wireless STA and AP base on network type. Logically
there are two interfaces in HF-LPT130A. One is for STA, and another is for AP. When HF-LPT130A
works as AP, other STA equipments are able to connect to HF-LPT130A module directly. Wireless
Networking with HF-LPT130A is very flexible.
Notes:
AP: that is the wireless Access Point, the founder of a wireless network and the centre of the network
nodes. The wireless router we use at home or in office may be an AP.
STA: short for Station, each terminal connects to a wireless network (such as laptops, PDA and other
networking devices) can be called with a STA device.
2.1.1. Basic Wireless Network Based On AP
Infrastructure: it’s also called basic network. It built by AP and many STAs which join in.
The characters of network of this type are that AP is the centre, and all communication between STAs
is transmitted through the AP. The figure following shows such type of networking.
Figure 8. HF-LPT130A Basic Wireless Network Structure

HF-LPT130A Low Power WiFi Module User Manual
2.2. Work Mode : Transparent Transmission Mode
HF-LPT130A module support serial interface transparent transmission mode. The benefit of this mode
is achieves a plug and play serial data port, and reduces user complexity furthest. In this mode, user
should only configure the necessary parameters. After power on, module can automatically connect to
the default wireless network and server.
As in this mode, the module's serial port always work in the transparent transmission mode, so users
only need to think of it as a virtual serial cable, and send and receive data as using a simple serial. In
other words, the serial cable of users’ original serial devices is directly replaced with the module; user
devices can be easy for wireless data transmission without any changes.
The transparent transmission mode can fully compatible with user’s original software platform and
reduce the software development effort for integrate wireless data transmission.
The parameters which need to configure include:
Wireless Network Parameters
Wireless Network NameSSID
Security Mode
Encryption Key
TCP/UDP Linking Parameters
Protocol Type
Link TypeServer or Client
Target Port ID Number
Target Port IP Address
Serial Port Parameters
Baud Rate
Data Bit
Parity (Check) Bit
Stop Bit
Hardware Flow Control
2.3. Encryption
Encryption is a method of scrambling a message that makes it unreadable to unwanted parties,
adding a degree of secure communications. There are different protocols for providing encryption, and
the HF-LPT130A module supports following:
WEP
WPA-PSK/TKIP
WPA-PSK/AES
WPA2-PSK/TKIP
WPA2-PSK/AES
2.4. Parameters Configuration
HF-LPT130A module supports two methods to configuration parameters: AT+instruction set.
High-Flying Electronics Technology Co., Ltd(www.hi-flying.com)
- 17 -
HF-LPT130A Low Power WiFi Module User Manual
AT+instruction set configuration means user configure parameters through serial interface command.
Refer to “AT+instruction set” chapter for more detail.
2.5. Firmware Update
HF-LPT130A module supports multiple upgrade methods:
UART upgrade
Local Network upgrade
2.6. SOCKET B Function
HF-LPT130A support double socket communication, the socket B function is disabled by default.
Figure 10. Socket B function demo
2.7. Multi-TCP Link Connection
When HF-LPT130A module SOCK A configured as TCP Server, it supports Multi-TCP link connection,
and maximum 5 TCP clients permitted to connect to HF-LPT130A module. User can realize multi-TCP
link connection at each work mode.
Multi-TCP link connection will work as following structure:
Upstream: All dates from different TCP connection or client will be transmitted to the serial port as a
sequence.
Downstream: All data from serial port (user) will be replicate and broadcast to every TCP connection
or client.
Detailed multi-TCP link data transmission structure as following figure:

After module restore factory default setting, all user configuration profile will lose.
User can access http://10.10.100.254 to set again, and user name and password is “admin”. HF-
LPT130A will restore to AP mode for factory default setting.

3.2. Usage Introduction
3.2.1. Software Debug Tools
High-Flying use two common software tools debugging and applying HF-LPT130A module.
(User can also select other tools used to debug serial port).
Serial Debugging Software: ComTools
Ethernet Debugging Software: TCPUDPDbg
3.2.2. Network Connection
User can select two methods to connect HF-LPT130A module base on dedicated application.
Use HF-LPT130A STA interface. HF-LPT130A and debug PC2 connect to a wireless AP,
another PC1 (or user device) connect to HF-LPT130A module with serial port:
Figure 25. STA Interface Debug Connection
Use HF-LPT130A AP interface. Debug PC2 connect to HF-LPT130A through wireless
connection, another PC1 (or user device) connect to HF-LPT130A module with serial port.

HF-LPT130A Low Power WiFi Module User Manual
Deault security mode: open,none;
User UART parameter setting:115200,8,1,None;
Default network parameter setting:TCP,Server,8899,10.10.100.254;
Module IP address: dhcp,0.0.0.0,0.0.0.0,0.0.0.0;
3.2.4. Module Debug
PC1 open “CommTools” program, setting the same serial port parameters with HF-LPT130A module
and open serial port connection.
Figure 27. “CommTools” Serial Debug Tools
PC2 open “TCPUDPDbg” program, and create a new connection. If HF-LPT130A configured as
Server mode, “TCPUDPDbg” Tools shall create “Client “mode connection. Or otherwise, create a
“Server” mode connection.
Figure 28. “TCPUDPDbg” Tools Create Connection
Then setting the TCP/UDP connection parameters. Default as following:

Then, click “Create” button to create a connection.
Figure 30. “TCPUDPDbg” Tools Connection
Now, in transparent transmission mode, data can be transferred from “CommTools” program to
“TCPUDPDbg” program, or in reverse. You can see data in receiver side will keep same as in sender
side.
3.3. Typical Application Examples
3.3.1. Wireless Control Application
Figure 31. Wireless Control Application
For this wireless control application, HF-LPT130A works as AP mode. Module’s serial port connects to
user device. So, control agent (Smart phone for this example) can manage and control the user device
through the wireless connection with HF-LPT130A module.

3.3.2. Remote Management Application
Figure 32. Remote Management Application
For this remote management application, HF-LPT130A works as STA mode and connects to Internet
through wireless AP. Module configured as TCP Client and communicates with remote TCP server at
Internet. Module’s serial port connects to user device.
So, user device’s data or sampling information can send to remote TCP server for storage or
processing. Also remote TCP server can send command to control and manage the user device
through the wireless network.
3.3.3. Transparent Serial Port Application
For this transparent serial port application, two HF-LPT130A modules connect as below figures to
build up a transparent serial port connection. One HF-LPT130A works as AP mode, another HF-
LPT130A works as STA mode. Make the STA device connects to AP.
