Sychip Wireless-Uart User Guide 1. Brief introduction 1.1 About this document This document describes how to use the SyChip Wireless-Uart EVK. It contains hardware installation, tcp/udp connect, AT configuration commands. Features: Support IEEE802.11b/g/n Wireless Standards. Support the wifi work at AP/STA mode. Support WEP, WPA, WPA2 Security. Support configurate uart interface easily. Support TCP/IP/UDP network protocol stack. Support send AT commands through uart to control the module. Single +3.
Sychip Wireless-Uart User Guide interfaces etc. (1)Power supply: Vcc Jump(red circle marked) provides two different modes of power supply. If jump to the right pin, the module power on through the uart. If jump to the left pin, the module power on through the +5v and GND pin. Note：Under normal circumstances using the uart power supply.
Sychip Wireless-Uart User Guide 2. Wireless-Uart EVK Operation 2.1 Hardware installation 1. Connect EVK and PC through USB cable. UART-USB converter boart USB cable to PC PC Figure 2. Wireless-Uart EVK Demo Under Wireless-Uart EVK normal mode, uart1 connected as shown in figure 2. Power supply through uart1. 2. Install USB-UART converter driver (FTDI D2xx driver). Customer can download from below website. http://www.ftdichip.com/Drivers/D2XX.htm 3. Please open device manager.
Sychip Wireless-Uart User Guide Figure 3. usb serial port 4. Then open serial terminal on the pc side, set the relevant parameters as shown in the following figure. Baudrate = 115200, Data_bits = 8, Stop Bits = 1, pariyt = none, Flow Control = none. These values are factory setting. Note: Under the configuration mode, the uart parameters are same to the factory setting[1]. Figure 4. uart configuration www.sychip.com.
Sychip Wireless-Uart User Guide 2.2 Work Mode 2.2.1 TCP Server mode Once EVK power on, the module start at factory setting mode[1]. 1. Configuration the device’s TCP/IP properties. Obtain an ip address automatically, show as figure 5. Figure 5. configuration the tcp/ip properties 2. Scan and join the module ap on the device. Show as figure 6. www.sychip.com.

Sychip Wireless-Uart User Guide 2.4 Webpage Demo 2.1 SystemInfo 2.3 AT configuration commands If customers press the configuration button when reset the device, the module into the configuration mode. AT commands can use the uppercase or lowercase letters, but the parameters must be set as special value, case-sensitive. AT commands application: • help /?: Input “help” or ”?” . This command can show all the commands and use information. • Tcp-client transmission configure.
Sychip Wireless-Uart User Guide (1) Uart parameters configuration If need to change the uart parameters: Example: BaudRate=9600, DataBits=8, StopBits=1, Parity=none, FlowCtrl=none. (2) Wifi parameters configuration If need to change the wifi mode as client: Example connect h3c ssid: sta/ap=sta, ssid=h3c, channel=1, security=open (3) Network parameters configuration If need to change the network parameters: Example enable the dhcpc, not use the static ip: dhcpd=0, dhcpc=1, ip_addr=0.0.0.0, net_mask=0.0.0.
Sychip Wireless-Uart User Guide Then press the reset button, or input at+reboot command, the module into the tcp-client transmission work mode. All AT commands parameters’s value and function please reference document[1]. 3. • Reference documents [1] Sychip wireless-uart interface.doc.
