HF-LPT120 module support internal on-board PCB antenna option. When customer select internal
antenna, you shall comply with following antenna design rules and module location suggestions:
For customer PCB, RED color region (8x10mm) can’t put componet or paste GND net;
Antenna must away from metal or high components at least 10mm;
Antenna can’t be shielded by any metal enclosure;
Figure 4. Suggested Module Placement Region
High-Flying suggest HF-LPB100 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-LPT120 supports two way of external antenna as the following picture show, The I-PEX interface
or the PAD interface(remove the I-PEX connector). The user may choose one of them. If user select
external antenna, HF-LPT120 modules must be connected to the 2.4G antenna according to IEEE
802.11b/g/n standards.
The antenna parameters required as follows:

Figure 8. HF-LPT120 Hardware Typical Application
Notes:
nReset- Module hardware reset signal. Input. Logics ―0‖ 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 ―0at least 10ms, then set 1‖ to keep module fully
reset.
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 4s 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.

(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.

2. FUNCTIONAL DESCRIPTION
2.1. Wireless Networking
HF-LPT120 module can be configured as both wireless STA and AP base on network type. Logically
there are two interfaces in HF-LPT120. One is for STA, and another is for AP. When HF-LPT120
works as AP, other STA equipments are able to connect to HF-LPT120 module directly. Wireless
Networking with HF-LPT120 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.

2.1.2. Wireless Network Based On STA
HF-LPT120 module support STA network mode as following figure,
