HF-LPB120 Low Power Wi-Fi Module User Manual
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 ( “Low” < 2s ) and loose to make the module go into “Smart Link “ config mode, waiting for APP to set password and other information. (See Appendix to download SmartLink APP)
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” and “ Smart Link” 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
“Smart Link “ config mode, this LED used to indicate APP to finish setting.
3. At normal mode, it
’s Wi-Fi link status indicator
High-Flying strongly suggest customer fan out this pin to LED.
UART1 Debug ：
1. Enable UART1 log information output by AT+NDBGL=1,1 via UART0, UART1 baud rate is fixed at 115200.
2. After UART1 is enabled, it will output system run log information and it can direct process AT command(No need to enter command mode like UART0)

Suggested Module Placement Region
High-Flying suggest HF-LPB120 module better locate in following region at customer board, which to reduce the effect to antenna and wireless signal, and better consult High-Flying technical people when you structure your module placement and PCB layout.
1.2.5. External Antenna
HF-LPB120 module supports internal antenna and external antenna(I-PEX or SMA) option for user dedicated application.
If user select external antenna, HF-LPB120 modules must be connected to the 2.4G antenna according to IEEE 802.11b/g/n standards.

2. FUNCTIONAL DESCRIPTION
2.1. Wireless Networking
HF-LPB120 module can be configured as both wireless STA and AP base on network type. Logically there are two interfaces in HF-LPB120. One is for STA, and another is for AP. When HF-LPB120 works as AP, other STA equipments are able to connect to HF-LPB120 module directly. Wireless
Networking with HF-LPB120 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.

2.2. Work Mode : Transparent Transmission Mode
HF-LPB120 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 c ompatible with user’s original software platform and reduce the software development effort for integrate wireless data transmission.
