This is the startup guide for SX-ULPAN-2401-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.

B) Configure IP Address
When it boots successfully, you will see shell> on the console. Set the IP address
first. The following sample uses 192.168.0.1.
C) Configure Region Code
Above example is for connection 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

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) to measure throughput. With a
response returned, the wireless LAN is successfully connected.
F) Throughput Test
This is how to run receiving and sending tests.
Receiving Test
Execute the following test command on the console of the
SX-ULPAN-2401-EVK.
Execute the throughput test program using PC’s Command Prompt.
