1.PRODUCT OVERVIEW
1.1. General Description
The HF-LPT271module is afully self-contained small form-factor, single stream, 802.11b/g/n Wi-Fi
+BLE module,which provide a wireless interface to any equipment with a Serial interface for data
transfer.This module 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 and BLE solution for a variety of applications.
The HF-LPT271 moduleemploys the world's lowest power consumption embedded architecture. It
hasbeen 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, andtransmit or
receive data on an infrequent basis.

nReload Pin (Button) function:
1. When this pin is set to “low” during module boot up, the module will enter wireless
firmware and config upgrade mode. This mode is used for customer manufacture.
See Appendix to download software tools for customer batch configuration and
upgrade firmware during mass production.
2. After module is powered up, short press this button (0.2s<“Low” <1.5s) and loose to
make the module go into SmartBLELinkconfig mode, waiting for APP to set
routerSSIDandpassword, config module connect to router. Recommend to use
SmartBleLink BLE method config, may use AT+SMARTCONFIG to choose other
config mode(SmartLink V8 and SmartAPLink).
See Appendix to download SmartBLELink, SmartLinkV8andSmartAPLinkAPP
3. After module is powered up, long press this button ( “Low” >4s ) and loose to make
the module recover to factory setting.
High-Flying strongly suggest customer fan out this pin to connector or button for
“Manufacture” upgrade or “SmartLink” application.
nReady Pin (LED) function(Low effective):
1. OS initial finished indicator. Only after this pin output low, can the UART function be
used.
nLink Pin (LED) function(Low effective):
1. At wireless firmware and config upgrade mode , this LED used to indicate configure
and upgrade status.
2. At “SmartLink” config mode, this LED isused to indicate APP to finish setting.
3. At normal mode, it’s Wi-Fi link status indicator.Output Low when STA mode connect
to router AP or other STA connect to it when in AP mode.
High-Flying strongly suggest customer fan out this pin to LED.
UART1 Debug ：
1. Is used for debug log or firmware program, baud rate 921600.
