Index

This is the startup guide for SX-ULPAN-2402-EVK, an evaluation board for the

SX-ULPAN-2401 wireless module.

Note: Specifications are subject to change

1. Introduction

The SX-ULPAN is an ultra-compact and low power wireless LAN module with

Qualcomm Atheros QCA4000 series radio. The module provides not only drivers

and supplicants to add WLAN functions to your product, but also other functions

to offload network protocol layers such as IPv4/IPv6, TCP/IP, HTTP, DNS, DHCP,

and so on. This allows MCU (Micro Controller Unit) with limited CPU

performance, ROM, RAM to get reliable Wi-Fi with ultra-low power consumption.

It offers device manufacturers to add reliable Wi-Fi to their tablets or other

IoE/IoT products.

2. Features

 IEEE802.11a/b/g/n (2.4GHz,5GHz Dual-Band)

 Support for 1 x 1:1 stream, 20MHz bandwidth mode

 Onboard PCB antenna (with a U.FL connector for add-on antenna)

 Surface mount type

 UART as host IF

 Security: WPS, WPA, WPA2, TKIP and AES hardware are supported.

 IPv4 and TCP/UDP Offload

 Offload for upper protocols like simple DHCP clients

8. Evaluation

This section will walk you through instructions from booting as a station to

connecting the radio to an AP for your evaluation/performance tests. Please refer to

the command reference for details and other modes/commands.

A) Booting

① Push the SX-ULPAN-2402-EVK SW1 (reset button).

② Open the COM port of mbed Serial Port by using the terminal software.

Set the serial communication as 115200N81.

As the SX-ULPAN-2402-EVK does not have a local echo function, characters

entered will not be displayed on the terminal. Enabling local echo of the

terminal software is recommended.

SX-ULPAN-2402-EVK

192.168.0.1

PC for data communication

192.168.0.10

Ethernet

AP

SX-ULPAN-SSID

B) Configure IP Address

When it boots successfully, you will see shell> on the console whenever you

press the enter key.

Set the IP address first. The following sample uses 192.168.0.1.

C) Configure Region Code

Above example is when connected as station. Refer to the command

specifications for settings for Access Point mode or other countries’ domain

code.

*Note: For the US, changing the domain code is not allowed by the Wireless

Radio Act

D) Connect to an Access Point

Boot as a STA. The following example is connecting to the WPA2-AES AP in SSID

SX-ULPAN-SSID.

E) Ping Check

After connecting the AP, check communications with ping. The following example

is sending a ping to the PC (192.168.0.10) for data transmission. With a

response returned, the wireless LAN is successfully connected.

F) Data Transfer

＜TCP server＞

Start the SX-ULPAN-2402-EVK as a TCP server to send/receive data to/from the

TCP client.

Boot the TCP server with Port 50000

Connect the PC for data transmission to the TCP50000 port.

Configure the following in a new connection of TeraTerm:

TCP/IP Host : 192.168.0.1

TCP Port# : 50000

Service : Others

shell>ATNSOCK=TCP

TCP handle: 0x442330

OK

shell>ATNSTCP=50000

OK

When it is connected from the client, it will turn to data mode with the following

message displayed.

Send data from the SX-ULPAN-2402-EVK.

With no send timeout (ATTO=) set after data input, data will be sent. Also, if the

data entered exceeds the buffer size (ATBSIZE=), the data will be sent.

Send data from the PC for data transmission

The data will be displayed on the SX-ULPAN-2402-EVK console.

To execute commands with TCP communication on, switch to online command mode

with the escape command.

Enter '+' 3 times at intervals of 1 sec or longer.

shell>Receiving from 0xc0a8000a Remote port:50437

Entering data mode

abcdefghijklmn

ABCDEFGHIJKLMN

switch to cmd mode.

Entering cmd mode

shell>

To return to data mode from online command mode, execute ATO command.

shell>ATO=
