1.6. Typical Application
1.6.1. Hardware Typical Application
Figure 8. HF-LPC100 hardware typical application
<Notes>:
nReset- module reset signal. Input, low level effective.
There is pull-up resister internal and no external pull-up required. When module power up or some
issue happened, MCU need assert nRST signal ―0‖ at least 10ms, then set‖ 1‖ to keep module fully
reset.
nLink- Module WIFI connection status indication. Output.
(This pin is recommend to connect to LED, indicate status when the module in wireless upgrade
mode)
When module connects to AP (AP associated), this pin will output ―0‖. This signal used to judge if
module already at WiFi connection status. Thers is pull-up resister internal and no external pull-up
required. If nLink function not required, can leave this pin open.
nReady- Module boot up ready signal. Output. Logics ―0‖ effective.
The module will output ―0‖ after normal boot up. This signal used to judge if module finish boot up
and ready for application or working at normal mode. If nReady function not required, can leave
this pin open.
nReload- Module restore to factory default configuration.Input. Logics ―0‖ effective.
(This pin is recommend to connect to button, is used to enter wireless upgrade mode)

User can de-assert nReload signal ―0‖ more than 3s through button or MCU pin, then release,
module will restore to factory default configuration and re-start boot up process.. If nReload
function not required, can leave this pin open.
UART0_TXD/RXD-UART port data transmit and receive signal.
1.7. Bluetooth Sonic Configuration
Sonic configuration is a Wi-Fi smart link method based on audio technology.(High Flying patent).
By its natural advantage of audio transmit, Bluetooth enable module receive audio information sent
from smart terminal. The APP on smart terminal compile the router‘s password and ID to audio
signal and play it through Bluetooth. Then the Wi-Fi module with Bluetooth will analysis the audio
signal and realize the Wi-Fi connection.
Nowadays Bluetooth is the standard deployment on smart terminal. Since the good support to
audio, this configuration has the minimum demand on smart terminals and greatly reduced the
configure steps and instabilities, no matter it is Bluetooth 2.1, 3.0 or 4.0, or kinds of Android
terminal, Iphone, Ipad . Any end users without technique background can quickly and easily
realize the Wi-Fi connection to any routers with 100% success ratio.

2.2. Work mode：Transparent Transmission Mode
HF-LPC100 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 parameter which needs to configure include:
Wireless network parameter
Wireless network name（SSID）
Security mode
Encryption key
Default TCP/UDP link parameter
Protocol type
Link type（server or Client）

2.3. UART Frame Scheme
2.3.1. UART Free-frame
Module will check the intervals between any two bytes when receiving UART data. If this interval time
exceeds defined value (50ms default), module will think it as the end of one frame and transfer this
free-frame to Wi-Fi port, or HF-LPC100 will receive UART data until 1000 bytes, then transfer 1000
bytes frame to Wi-Fi port.
Default interval time is 50ms, once the interval over 50ms, it is the end of one frame.
In addition, the interval can be set as 10ms via AT command to meet customer‘s requirement on
UART efficiency. According to our test, if set at 10ms, the circle WIFI UART WIFI delay will be
around 40-50 ms if data is small.
If the interval is 10ms, and customers MCU can not send next byte within 1oms, then the UART data
may be divided as fragment.
Through AT command AT+UARTTE=fast/normal to set interval time, fast means 10ms, normal
means 50ms.
2.3.2. UART Auto-Frame
For data frame on UART, Module can be more effective by open UART auto-frame function. HF-
LPC100 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‖
