2. FUNCTIONAL DESCRIPTION
2.1. Wireless Networking
HF-LPB100 module can be configured as both wireless STA and AP base on network type. Logically
there are two interfaces in HF-LPB100. One is for STA, and another is for AP. When HF-LPB100
works as AP, other STA equipments are able to connect to wireless LAN via HF-LPB100 module.
Wireless Networking with HF-LPB100 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)
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 9. HF-LPB100 Basic Wireless Network Structure
2.1.2. Wireless Network Based On AP+STA
HF-LPB100 module support AP+STA network mode, means module support one AP interface and
one STA interface at the same time, as following figure,
High-Flying

Shanghai High-Flying Electronics Technology Co., Ltd
www.hi-flying.com
- 21 -
Figure 10. HF-A11 AP+STA Network Structure
When module enables AP+STA function, Module’s STA interface can connect with router and connect
to TCP server in the network. At the same time, module’s AP interface is also active and permit
phone/PAD to connect through TCPB, then phone/PAD can control user device and and setting the
module parameters,
The advantage of AP+STA mode is:
Users can easily setting and track user device through Phone/PAD and not change the
orginal network setting.
Users can easily setting module’s parameters through WiFi when module works as STA
mode.
2.2. Work Mode : Transparent Transmission Mode
HF-LPB100 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 Name（SSID）
Security Mode
Encryption Key

2.3. UART Frame Scheme
2.3.1. UART Free-Frame
HF-LPB100 support UART free-frame function. If user select open this function, module will check the
intervals between any two bytes when reciving UART data. If this interval time exceeds defined value
(50ms default), HF-LPB100 will think it as the end of one frame and transfer this free-frame to WiFi
port, or HF-LPB100 will receive UART data untill 1000 bytes, then transfer 1000 bytes frame to WiFi
port.
HF-LPB100’s default interval time is 50ms. User can also set this interval to fast (10ms) through AT
command. But user have to consider if user MCU can send UART data with 10ms interval ,or the
UART data may be divide as fragment.
Through AT command: AT+UARTTE=fash/normal, user can set the interval time: fast (10ms) and
normal (50ms).
2.3.2. UART Auto-Frame
HF-LPB100 support UART auto-frame function. If user select open this function and setting auto-
frame trigger length and auto-frame trigger time parameters, then module will auto framing the data
which received from UART port and transmitting to the network as pre-defined data structure.
Auto-frame trigger length: The fixed data length that module used to transmitting to the
network.
Auto-frame trigger time: After the trigger time, if UART port received data can’t reach auto-
frame trigger length, then module will transmitting available data to the network and bypass
the auto-frame trigger length condition.
Detailed UART auto-frame function can refer to AT+ instruction set “UARTF/UARTFT/UARTFL”
introduction.

2.4. 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-LPB100 module supports following:
WEP
WPA-PSK/TKIP
WPA-PSK/AES
WPA2-PSK/TKIP
WPA2-PSK/AES
2.5. Power Save Scheme
HF-LPB100 module can work at two modes based on different power save scheme:
Normal (Active/Sleep) Mode - AP Associated, WiFi ON/OFF based on internal control
Standby Mode - Non AP Associated, WiFi Shut dwon
Normal (Active/Sleep) Mode Normal mode is no DTIM related (Default mode), module will monitor
the interval to Active/Sleep.
Standby Mode allows the WiFi circuitry to be powered down, which results in the lowest sleep current,
but at the expense of longer wake up times. This is due to the module associating with the access
point every time when it wakes up. The intent of this option is to allow for longer sleep times. Standby
mode can through AT+MSLP command or trigger “Sleep_RQ” pin to go in.
The standby mode status and wakeup method as follows: For standby mode, module provides two
wakes up options, user can select one or whole as the module wake up option. Refer to AT Instruction
(Power Management Instruction Set) for more detailed setting.

Sleep _RQ Pin Wake Up Option allows an external microcontroller to determine when HF-LPB100
should sleep and when it should wake by controlling the “Sleep_RQ” and “Sleep_ON” pin. at the
standby mode, user can de-assert this pin low “0”, after 1’s assert to high ”1” to put the module to
wake up the module. If user doesn't use pin sleep function, can leave this pin open.
Sleep _RQ Pin Wake Up Option allows an external microcontroller to de-assert “Reset” pin to low
