Wireless Networking HF-LPT200 module can be configured as both wireless STA and AP base on network type. Logically there are two interfaces in HF-LPT200. One is for STA, and another is for AP. When HF-LPT200 works as AP, other STA equipments are able to connect to HF-LPT200 module directly. Wireless Networking with HF-LPT200 is very flexible. Notes: AP: that is the wireless Access Point, the founder of a wireless network and the centre of the network nodes. The wireless router we use at home or in office may be an AP. STA: short for Station, each terminal connects to a wireless network (such as laptops, PDA and other networking devices) can be called with a STA device. 2.1.1. Basic Wireless Network Based On AP (Infrastructure) Infrastructure: it’s also called basic network. It built by AP and many STAs which join in. The characters of network of this type are that AP is the centre, and all communication between STAs is transmitted through the AP. The figure following shows such type of networking. Figure 9. HF-LPT200 Basic Wireless Network Structure 2.1.2. Wireless Network Based On AP+STA HF-LPT200 module support AP+STA network mode, means module support one AP interface and one STA interface at the same time, as following figure,
High-FlyingHF-LPT200 Low Power WiFi Module User Manual Shanghai High-Flying Electronics Technology Co., Ltd(www.hi-flying.com) - 19 - Figure 10. HF-LPT200 AP+STA Network Structure When module enables AP+STA function, Module’s STA interface can connect with router and connect to TCP server in the network. At the same time, module’s AP interface is also active and permit phone/PAD to connect through TCPB, then phone/PAD can control user device and and setting the module parameters, The advantage of AP+STA mode is:  Users can easily setting and track user device through Phone/PAD and not change the orginal network setting.  Users can easily setting module’s parameters through WiFi when module works as STA mode. 2.2. Work Mode : Transparent Transmission Mode HF-LPT200 module support serial interface transparent transmission mode. The benefit of this mode is achieves a plug and play serial data port, and reduces user complexity furthest. In this mode, user should only configure the necessary parameters. After power on, module can automatically connect to the default wireless network and server. As in this mode, the module's serial port always work in the transparent transmission mode, so users only need to think of it as a virtual serial cable, and send and receive data as using a simple serial. In other words, the serial cable of users’ original serial devices is directly replaced with the module; user devices can be easy for wireless data transmission without any changes. The transparent transmission mode can fully compatible with user’s original software platform and reduce the software development effort for integrate wireless data transmission. The parameters which need to configure include:
High-FlyingHF-LPT200 Low Power WiFi Module User Manual Shanghai High-Flying Electronics Technology Co., Ltd(www.hi-flying.com) - 20 -  Wireless Network Parameters  Wireless Network Name（SSID）  Security Mode  Encryption Key  TCP/UDP Linking Parameters  Protocol Type  Link Type（Server or Client）  Target Port ID Number  Target Port IP Address  Serial Port Parameters  Baud Rate  Data Bit  Parity (Check) Bit  Stop Bit  Hardware Flow Control 2.3. UART Frame Scheme 2.3.1. UART Free-Frame HF-LPT200 support UART free-frame function. If user select open this function, module will check the intervals between any two bytes when reciving UART data. If this interval time exceeds defined value (50ms default), HF-LPT200 will think it as the end of one frame and transfer this free-frame to WiFi port, or HF-LPT200 will receive UART data untill 1000 bytes, then transfer 1000 bytes frame to WiFi port. HF-LPT200’s default interval time is 50ms. User can also set this interval to fast (10ms) through AT command. But user have to consider if user MCU can send UART data with 10ms interval ,or the UART data may be divide as fragment. Through AT command: AT+UARTTE=fash/normal, user can set the interval time: fast (10ms) and normal (50ms). 2.3.2. UART Auto-Frame HF-LPT200 support UART auto-frame function. If user select open this function and setting auto-frame trigger length and auto-frame trigger time parameters, then module will auto framing the data which received from UART port and transmitting to the network as pre-defined data structure.  Auto-frame trigger length: The fixed data length that module used to transmitting to the network.  Auto-frame trigger time: After the trigger time, if UART port received data can’t reach auto-frame trigger length, then module will transmitting available data to the network and bypass the auto-frame trigger length condition.
High-FlyingHF-LPT200 Low Power WiFi Module User Manual Shanghai High-Flying Electronics Technology Co., Ltd(www.hi-flying.com) - 21 - Detailed UART auto-frame function can refer to AT+instruction set “UARTF/UARTFT/UARTFL” introduction. 2.4. Encryption Encryption is a method of scrambling a message that makes it unreadable to unwanted parties, adding a degree of secure communications. There are different protocols for providing encryption, and the HF-LPT200 module supports following:  WEP  WPA-PSK/TKIP  WPA-PSK/AES  WPA2-PSK/TKIP  WPA2-PSK/AES 2.5. Parameters Configuration HF-LPT200 module supports two methods to configuration parameters: Web Accessing and AT+instruction set. Web accessing means users can configure parameters through Web browser.
