1. Overview:HLK-WIFI-TTL001 is a WLAN Module based on UART Serial .

1.1. Main Function        Support for UART data serial, four baud rate options: 19200 / 38400 / 57600 / 115200bps.        Wireless data rates support the 802.11b Standard, the maximum rate is 11Mbps.        Integrate the functions of 802.11 MAC protocol Software.        Support for the STA appliances in the Infrastructure Network.        Support for the OPEN/WEP mode authentication.        Support for the wep64/wep128/ccmp/wpi data encryption transmission in theshared key mode        Support for the automatic networking mode and manual networking mode.        In the automatic networking mode,the module can automatically scan thetarget network, and automatically connect when disconnection.        In the manual networking mode,operation of connect and disconnect is touched off by order,this supports a flexible control space.        Support the network data transmission in RAW/UDP/TCP format.        Support seven groups of the basic parameters set, and can connect to seven target networks the most.        Support to configure the parameters through user serial.        Support to upgrade the firmware on line by the internet.

1.2. Typical Applications1.2.1. Wireless POS MachineIn a Wireless Bus System based on the WLAN technique, carheld or handheldPOS machine in each bus equips with a h-WiFi module, and AP is fixed in the BusTerminus. When buses reach the terminus, wireless POS machine always does theidentification automatically, then connect to the AP, and Operational Data in POSmachines is uploaded to Data Center Server in Bus Terminus through AP.1.2.2. Wireless Monitoring and Control SystemSerial devices networking(TCP/IP) has been a trendy of Industrial-sitenetworking, but Field wiring and the following construction, transformation cost oftenbecome a bottleneck of serial devices networking. WLAN modules embed in theseMonitoring and Control Terminals ,which support serial ,not only can absolves thedifficulty of wiring, but also reduces the construction cost, and it especially adapts tothe devices about Industrial Environment and Factory Automation Systems, SiteMonitoring System and etc.
