Product overview

WizFi630S is a gateway module that includes the UART protocol and TCP/IP protocol into the IEEE802.11 b/g/n wireless LAN protocol. WizFi630S enables a device with a serial interface to connect to LAN or WLAN for remotely control, measuring, and administration. WizFi630S can also work as an IP router because of its internally embedded switch.

WizFi630S uses interfaces like Serial (UART), LAN, Wi-Fi (WLAN) to perform functions such as Serial-To-Wi-Fi, Serial-To-Ethernet, Ethernet-To-Wi-Fi. Users can connect to WizFi630S's internal web server or use serial commands for simple Wi-Fi settings; not only serial devices but 8/16/32 bit micro controllers can also use UART for simple Wi-Fi settings.

WizFi630S can significantly reduce the processes for wireless module design, testing, and certification. Therefore, WizFi630S can be the best solution for users who lack wireless network experience.

WizFi630S follows the 802.11b/g/n standard and supports up to 150Mbps speed in the wireless interface. WizFi630S provides a test board, PC software, and documents so that anyone can develop a wireless solution.

Operation Mode

Access Point

In Access Point (AP) mode, all Ethernet ports and the wireless interface are bridged together. The wired and wireless interfaces share the same IP address space. The DHCP Server function is disabled, and the WizFi630S does not assign IP addresses. The module sends periodic broadcast packets to stations and maintains connections.

Diagram: AP Mode Network Setup

This diagram shows the WizFi630S in AP Mode. It is connected to multiple PCs via LAN ports (LAN #0, LAN #1, LAN #2). The WLAN interface is optional. DHCP services are indicated.

Gateway

In Gateway (Router) mode, interfaces are separated into WAN (Internet Network), LAN (Sub Private Network, e.g., 192.168.16.xxx), and Wireless (Sub Private Network). Port #0 is assigned as the WAN Port. The WizFi630S periodically sends broadcast packets to the sub-LAN (including LAN ports) and maintains connections with stations.

Diagram: Gateway Mode Network Setup

This diagram illustrates the WizFi630S in Gateway/Router (G/W) Mode. The Internet connects via LAN #0 (WAN). NAT and DHCP are enabled. LAN #1, LAN #2, and WLAN interfaces connect to devices with private IP addresses (192.168.16.XXX).

Client (Station)

In Client (Station) mode, the Wireless Interface is assigned as the WAN Port, and all Ethernet Ports are bound to the LAN Port. The WizFi630S automatically connects to a pre-configured AP upon reboot. Devices connected via the LAN port receive private IPs. The WizFi630S periodically sends PING packets to the AP Gateway to maintain the connection.

Diagram: Client Mode Network Setup

This diagram shows the WizFi630S in Client Mode. The Internet connects via WLAN (WAN). NAT and DHCP are enabled. LAN #0, LAN #1, and LAN #2 interfaces connect to devices with private IP addresses (192.168.16.XXX).

AP-Client mode

This mode is similar to Station mode, but the Wireless Interface operates as both a client to an AP and an AP simultaneously. The WizFi630S periodically sends broadcast packets to the sub-LAN (LAN ports included) and maintains connections with stations.

Diagram: AP-Client Mode Network Setup

This diagram shows two scenarios: WizFi630S in AP Client Mode and WizFi630S in AP Client Mode (Multi Bridge Mode). Both connect to the Internet via WLAN. NAT and DHCP are indicated. LAN ports are connected to devices.

Configuration Methods

There are two primary methods for configuring the WizFi630S module: Web Manager and Command Mode (CLI).

Configuration using Web Manager

To use the Web Manager, a network connection must be established between your PC and the module. This can be done wirelessly (connecting your PC to the WizFi630S AP) or wired (connecting the WizFi630S-EVB's Ethernet interface to your PC's network). Once connected, you can access the Web Manager via a web browser.

Access is typically through the IP address 192.168.1.1 or the hostname http://wizfi630s/. The initial login screen may indicate that no password is set, prompting the user to configure a root password for security.

Diagram: Web Manager Login and Status Screen

Screenshots display the Web Manager login interface, showing fields for Username and Password, with an option to configure the password. Another screenshot shows the status/overview page, detailing system information like Model, Firmware Version, Kernel Version, Uptime, Load Average, Memory usage, and network status (IP address, SSID, Mode).

Configuration using Command mode

The Command Line Interface (CLI) allows users to control the module's operations. It can be accessed via a serial port connection using a terminal emulation program.

Diagram: Connecting CLI via Serial Port

An image of the WizFi630S-EVB board highlights the Micro USB port (for CLI) and Serial 2 port (for CLI, USER UART). It also indicates the option to choose the CLI port (RS232/USB).

Default serial settings are: Baud Rate 115200, Data Size 8bit, Parity None, and Flow Control None (not supported).

The output of U-Boot and the BusyBox shell prompt are shown, including a warning about the absence of a root password and instructions to use the 'passwd' command.

Network Settings

Network Settings allow you to view the status of the WizFi630S module's interfaces and configure IP and related protocols. The module has two interfaces: Ethernet (eth0) and WLAN (ra0, apcli0). Some settings require a reboot to take effect.

Interfaces

Interface sections define logical networks for IP address settings, aliases, routes, and physical interface names.

Web Manager

When connecting to an existing network via the WAN port, configuration is done on the WAN tab. If the network supports DHCP Server, set the 'Protocol' to 'DHCP Client'. If DHCP is not supported or a static IP is preferred, set 'Protocol' to 'Static address' and enter the network information.
