3. FUNCTIONAL DESCRIPTION
3.1. Wireless Networking
HF-LPB200 module can be configured as both wireless STA and AP base on network type. Logically
there are two interfaces in HF-LPB200. One is for STA, and another is for AP. When HF-LPB200
works as AP, other STA equipments are able to connect to wireless LAN via HF-LPB200 module.
Wireless Networking with HF-LPB200 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.
3.1.1. 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 11. HF-LPB200 Basic Wireless Network Structure
3.1.2. Wireless Network Based On AP+STA
HF-LPB200 module support AP+STA network mode, means module support one AP interface and one
STA interface at the same time, as following figure,
HF-LPB200 Low Power WiFi Module User Manual
Shanghai High-Flying Electronics Technology Co., Ltd
www.hi-flying.com
- 20 -
Figure 12. 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.
3.1.3. Wi-Fi Direct Network
Wi-Fi Direct standard permits the wireless connection without AP router. Like blue tooth, this standard
use point to point interconnection and all devices connect each other and transmit data withour router.
HF-LPB200 module support following Wi-Fi Direct networking:
1:1 P2P Networking;
1:N P2P Networking (TBD);

Figure 14. HF-LPB200 1:N P2P Networking
3.2. Work Mode : Transparent Transmission Mode
HF-LPB200 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
TCP/UDP Linking Parameters
Protocol Type
Link Type（Server or Client）
Target Port ID Number
Target Port IP Address
Serial Port Parameters
Baud Rate
Data Bit
Parity (Check) Bit
Stop Bit

3.3. UART Frame Scheme
HF-LPB200 support UART free-frame function. Module will check the intervals between any two bytes
when reciving UART data. If this interval time exceeds defined value (50ms default), HF-LPB200 will
think it as the end of one frame and transfer this free-frame to WiFi port, or HF-LPB200 will receive
UART data untill 1400 bytes, then transfer 1400 bytes frame to WiFi port.
HF-LPB200‟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).
3.4. 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-
LPB200 module supports following:
WEP
WPA-PSK/TKIP
WPA-PSK/AES
WPA2-PSK/TKIP
WPA2-PSK/AES
3.5. Multi-TCP Link Connection
When HF-LPB200 module configured as TCP Server, it supports Multi-TCP link connection, and
maximum eight TCP clients permit to connect to HF-LPB200 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 duplicate and broadcast to every TCP connection or client.
Detailed multi-TCP link data transmition structure as following figure:

Figure 15. Multi-TCP Link Data Transmition Structure
3.6. Power Save Scheme
HF-LPB200 module can work at three modes based on different power save scheme:
Normal Mode (Active/Sleep) - AP Associated, Wi-Fi ON/OFF based on internal control
Wi-Fi Wakeup Mode (Standby) - AP Associated, MCU OFF, Wi-Fi wakeup
Deep Sleep Mode (Shutdown) - Non AP Associated, Wi-Fi Shut dwon, MCU Sleep
Pin/Timer Wakeup
Normal Mode (Active/Sleep) Normal mode means Wi-Fi circuitry works at IEEE PS mode and MCU
circuitry work at normal mode. That‟s the default working mode for HF-LPB200 to communication with
outside and no data transceiving latency.
Wi-Fi Wakeup Mode (Standby) allows the MCU circuitry to be powered down and still keep Wi-Fi AP
associated, which save more power compared with normal mode and module can be wake up through
Wi-Fi at network server side.
Deep Sleep Mode (Shutdown) allows the Wi-Fi circuitry and MCU 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. Deep sleep mode can trigger “Sleep_RQ” pin to go in.
The Difference between Wi-Fi Wakeup and Deep Sleep mode as follows:

Timeout Wake Up
Wi-Fi Wake Up
Pin Wake Up Option allows an external microcontroller to determine when HF-LPB200 should sleep
and when it should wake by controlling the “Sleep_RQ” and “Sleep_ON” pin. at the Wi-Fi wakeup
mode/Deep Sleep 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.
Timeout Wake Up Option allows the sleep timeout period to be configured through the use of AT
Instruction.In this option, the module will exit sleep based on the <Timeout> AT Instruction parameters
Wi-Fi Wake Up Option only applicatable for Wi-Fi Wakeup mode, which provide the flexibility for
network server or user to control and manage the Wi-Fi device to go into power save mode, but still
keep the Wi-Fi link associated, Refer to AT Instruction to know more about the WiFi wakeup command.

page setting function.
5.1.1. Switch to Configuration Mode
Two steps to finish switching from transparent transmission mode to configuration mode.
UART input “+++”, after module receive “+++”, and feedback “a” as confirmation.
UART input “a”, after module receive “a” and feedback “+ok” to go into AT+
instruction set configuration mode.
