详细说明： HLK-UART-WIFI is a WLAN Module based on UART Serial from Hi-Link. 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 the shared key mode Support for t he automatic networking mode and manual networking mode. In the automatic networking mode，the module can automatically scan the target 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 Applications 1.2.1. Wireless POS Machine In a Wireless Bus System based on the WLAN technique, carheld or handheld POS machine in each bus equips with a h-WiFi module, and AP is fixed in the Bus Terminus. When buses reach the terminus, wireless POS machine always does the identification automatically, then connect to the AP, and Operational Data in POS machines is uploaded to Data Center Server in Bus Terminus through AP. 1.2.2. Wireless Monitoring and Control System Serial devices networking（TCP/IP） has been a trendy of Industrial-site networking, but Field wiring and the following construction, transformation cost often become a bottleneck of serial devices networking. WLAN modules embed in these Monitoring and Control Terminals ,which support serial ,not only can absolves the difficulty of wiring, but also reduces the construction cost, and it especially adapts to the devices about Industrial Environment and Factory Automation Systems, Site Monitoring System and etc. SOC芯片，性价比极高，质量稳定，内置WiFi协议栈和串口传输协议， 接口信号5V、地、RX 、TX 四线连接； ◆ 模块简洁、体积小，22*60*7 mm； ◆ 用户接口开发简单快捷，串口驱动 ； ◆ MSC51/PIC/ARM7 等 8、32 位单片机轻易驱动，驱动代码极少； 产品参数 ◆ 支持UART数据接口，波特率：19.2k / 38.4k / 57.6k / 115.2k bps ； ◆ 无线数据速率支持802.11b，最高速率11M ； ◆ 集成802.11 MAC协议软件功能； ◆ 支持基础网络中的STA 应用； ◆ 支持OPEN/WEP方式的鉴权； ◆ 支持共享密钥方式的wep64/wep128 数据加密传输； ◆ 在自动联网模式下，模块能自动扫描目标网络，断线自动重连 ； ◆ 在手动联网模式下，通过命令触发连接和断开，用户灵活控制； ◆ 支持RAW/UDP/TCP格式的网络数据传输； ◆ 支持7 组基本参数设置，最多可以连接7 个目的网络； ◆ 支持通过用户接口进行参数配置； ◆ 支持固件程序通过网络在线升级； 本文来自CSDN博客，转载请标明出处：http://blog.csdn.net/qingfeng12g/archive/2010/03/07/5354341.aspx ...展开收缩
