1. HARDWARE INTRODUCTION

HF-LPX30 series is a low-power, high-performance Wi-Fi module supporting the

IEEE 802.11b/g/n wireless standard, with a maximum frequency of 160MHz,

352KB/384KB RAM, 1MB or 2MB Flash.

High Flying provides the EVK development board for the corresponding module for

functional testing and development.

2. SERIAL PORT SETTINGS

2.1. SecureCRTSerial Port Tool SecureCRT

Download address:

http://www.hi-flying.com/index.php?route=download/category&path=1_4

Unzip the folder, open to find the SecureCRT executable, and click Open.

Connect the development board to the computer with a micro USB cable and install the

USB serial port driver:

http://www.hi-flying.com/download-center-1/applications-1/driver-ft232r

Click the Quick Connect button to create a connection.

2.2. Setting Serial Port Parameters

Agreement: Serial

Port: The port to which the computer is actually connected (available via My Computer ->

Device Manager -> Ports (COM and LPT) as shown.) ）

The default factory serial port parameters are as shown in the figure below. If necessary,

the AT+UART command can be used to modify the serial port parameters of the device.

2.3. SecureCRT Software Usage

Open the tool Button Bar function.

Right-click the Edit button function to open the tool button function, you can add the

commonly used send data, here add the "+++" and "a" required to enter the command mode.

Can also edit and add commonly used AT commands with \r as the terminator.

Click the corresponding button to send "+++", the module responds with "a" and then

clicks to send "a". After the module returns "+ok", it enters the command mode.

After entering the command mode, the module can send commands, and the data input

by the main interface will be sent out immediately. The displayed data is echoed. The data in

the lower command bar will be sent only after pressing the Enter key (It needs to be displayed

after the tool is enabled.) The data sent in the command bar is marked with a carriage return,

so there is no need to add "\r" as the button bar.

The Command Window is displayed.

Notes：

1、Switching the transparent transmission mode to the command mode For

detailed procedures, refer to the user manual.

2、It is also possible to directly send the AT command in the transparent

transmission mode, and use the AT+CMDPW command to enable this function.

See the chip manual for details.

3、In the batch stage, High Flying can support the module that burns the

customized parameters, so the default parameters do not need to be configured

by the MCU.

3. TEST CASE

The software used in this article can be obtained from the High Flying website.

3.1. Transparent Transmission of UART and Wi-Fi Module in AP Mode

The test topology is as follows:

After power-on, the Power light is on, the Ready light is on, and the module is working

properly.

After the computer Wi-Fi searches for the AP hot spot of this device, it connects.

Open the TCP & UDP Debug software, create a TCP client, fill in the module's IP address

and TCP information (default AP IP: 10.10.100.254, TCP Server, 8899 port, available

AT+LANN, AT+NETP command to modify the default information), click 【Connect】establish

connection.

The two-way transmission and reception of data is completed as shown below.
