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.

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.
