1. PRODUCT OVERVIEW
1.1. General Description
1.1.1 Key Application
Remote equipment monitoring
Asset tracking and telemetry
Security
Industrial sensors and controls
Home automation
Medical devices
The HF-LPB135 is a fully self-contained small form-factor, single stream, 802.11b/g/n Wi-Fi module,
which provide a wireless interface to any equipment with a Serial interface for data transfer.HF-
LPB135 integrate MAC, baseband processor, RF transceiver with power amplifier in hardware and all
Wi-Fi protocol and configuration functionality and networking stack, in embedded firmware to make a
fully self-contained 802.11b/g/n Wi-Fi solution for a variety of applications.
The HF-LPB135 employs the world's lowest power consumption embedded architecture. It has been
optimized for all kinds of client applications in the home automation, smart grid, handheld device,
personal medical application and industrial control that have lower data rates, and transmit or receive
data on an infrequent basis.
The HF-LPB135 series Wi-Fi modules provide different package with different size called HF-
LPB130/HF-LPT230/HF-LPT130A/B(T means tiny). It is pin to pin compatible for HF-LPB100/HF-
LPB120, HF-LPT200/HF-LPT220, HF-LPT100F/HF-LPT120A modules.

HF-LPB135 Series Low Power WiFi Module User Manual
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
this device may not cause harmful interference, and
this device must accept any interference received, including interference that may cause
undesired operation.
Any changes or modifications not expressly approved by the party responsible for compliance
could void the user’s authority to operate the equipment.
Please notice that if the FCC identification number is not visible when the module is installed
inside another device, then the outside of the device into which the module is installed must also
display a label referring to the enclosed module. This exterior label can use wording such as the
following: “Contains FCC ID:2ACSV-HF-LPB135” any similar wording that expresses the same
meaning may be used.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20cm
between the radiator & your body. This transmitter must not be co-located or operating in
conjunction with any other antenna or transmitter.
The module is limited to OEM installation ONLY.
The OEM integrator is responsible for ensuring that the end-user has no manual instruction to
remove or install module.
The module is limited to installation in mobile application.
A separate approval is required for all other operating configurations, including portable
configurations with respect to Part 2.1093 and difference antenna configurations.
There is requirement that the grantee provide guidance to the host manufacturer for compliance
with Part 15B requirements.
The OEM integrator is responsible for ensuring that the end-user has no manual instructions to
remove or install module.
The module is limited to installation in mobile or fixed application.

Due to PWM pin is internal weak pull-up. So when these pins are used for LED bulb
application, suggest to add strong pull-down resistor to revent the lulb on when boot.
Note：nReload pin is also used for special function, when use this pin for PWM bulb
application and add external pull-down resistor, this will cause the module wait 1 second
when bootup(wait “space” key to etner bootloader). Contact us to provice special
bootloader in order to remove this wait time.

2.1.1. Basic Wireless Network Based On AP
Figure 8. HF-LPB135 Basic Wireless Network Structure
2.1.2. Wireless Network Based On STA
Figure 9. HF-LPB135 STA Network Structure
HF-LPB135 module can be configured as both wireless STA and AP base on network type. Logically
there are two interfaces in HF-LPB135. One is for STA, and another is for AP. When HF-LPB135
works as AP, other STA equipments are able to connect to HF-LPB135 module directly. Wireless
Networking with HF-LPB135 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.
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.
HF-LPB135 module support STA network mode.

HF-LPB135 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:
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-LPB135 module supports following:
HF-LPB135 module supports two methods to configuration parameters: AT+instruction set.

HF-LPB135 support double socket communication, the socket B function is disabled by default.
When HF-LPB135 module SOCK A configured as TCP Server, it supports Multi-TCP link connection,
and maximum 5 TCP clients permitted to connect to HF-LPB135 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.

side.
For this wireless control application, HF-LPB135 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-LPB135 module.

For this remote management application, HF-LPB135 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.
For this transparent serial port application, two HF-LPB135 modules connect as below figures to build
up a transparent serial port connection. One HF-LPB135 works as AP mode, another HF-LPB135
works as STA mode. Make the STA device connects to AP.

2. Any other input or wrong step to UART port will cause the module still works as original mode
(transparent transmission).
3. “+++” and “a” should be input in a certain period of time to make the module switch to configuration
mode. Like the following sequence.
After set AT+CMDPW command value, the module support response AT command for special data
format as “prefix”+”AT comman”+”\r”, it is very useful for query some status in transparent
transmission mode. It saves the steps of changing to AT command mode.
The following example, we first set AT+CMDPW=HF, then send the following data in transparent
mode, and get the AT command response. This data won’t be sent to socket.
User can input AT+Instruction through hyper terminal or other serial debug terminal, also can program
the AT+Instruction to script. User can also input “AT+H” to list all AT+Instruction and description to
