2. FUNCTIONAL DESCRIPTION
2.1. Wireless Networking
HF-LPT100 module can be configured as both wireless STA and AP base on network type. Logically
there are two interfaces in HF-LPT100. One is for STA, and another is for AP. When HF-LPT100
works as AP, other STA equipments are able to connect to wireless LAN via HF-LPT100 module.
Notes:
ng
Wireless Networking with HF-LPT100 is very flexible.
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.
Basic Wireless Network Based On AP (Infrastructure)
yi
2.1.1.
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
ig
h-
Fl
is transmitted through the AP. The figure following shows such type of networking.
Figure 8.
2.1.2.
HF-LPT100 Basic Wireless Network Structure
Wireless Network Based On AP+STA
HF-LPT100 module support AP+STA network mode, means module support one AP interface and one
STA interface at the same time, as following figure,

HF-LPB Low Power WiFi Module User Manual
HF-A11 AP+STA Network Structure
When module enables AP+STA function, Module’s STA interface can connect with router and connect
yi
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
Fl

orginal network setting.

Users can easily setting module’s parameters through WiFi when module works as STA
ig
h-
mode.
2.2. Work Mode : Transparent Transmission Mode
HF-LPT100 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-LPT100 support UART free-frame function. If user select open this function, module will check the
yi
intervals between any two bytes when reciving UART data. If this interval time exceeds defined value
(50ms default), HF-LPT100 will think it as the end of one frame and transfer this free-frame to WiFi
port, or HF-LPT100 will receive UART data untill 1000 bytes, then transfer 1000 bytes frame to WiFi
Fl
port.
HF-LPT100’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
ig
h-
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-LPT100 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 autoframe 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”
