High-FlyingHF-LPB Low Power WiFi Module User Manual Shanghai High-Flying Electronics Technology Co., Ltd www.hi-flying.com - 18 - 2. FUNCTIONAL DESCRIPTION 2.1. Wireless Networking HF-LPT100 module can be configured as both wireless STA and AP base on network type. Logically there are two interfaces in HF-LPT100. One is for STA, and another is for AP. When HF-LPT100 works as AP, other STA equipments are able to connect to wireless LAN via HF-LPT100 module. Wireless Networking with HF-LPT100 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 8. HF-LPT100 Basic Wireless Network Structure 2.1.2. Wireless Network Based On AP+STA HF-LPT100 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-LPB Low Power WiFi Module User Manual Shanghai High-Flying Electronics Technology Co., Ltd www.hi-flying.com - 19 - Figure 9. HF-A11 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-LPT100 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:  Wireless Network Parameters  Wireless Network Name（SSID）  Security Mode  Encryption Key
High-FlyingHF-LPB Low Power WiFi Module User Manual Shanghai High-Flying Electronics Technology Co., Ltd www.hi-flying.com - 20 -  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-LPT100 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-LPT100 will think it as the end of one frame and transfer this free-frame to WiFi port, or HF-LPT100 will receive UART data untill 1000 bytes, then transfer 1000 bytes frame to WiFi port. HF-LPT100’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-LPT100 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. Detailed UART auto-frame function can refer to AT+ instruction set “UARTF/UARTFT/UARTFL” introduction.

FCC STATEMENT 1. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference. (2) This device must accept any interference received, including interference that may cause undesired operation. 2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: 　 Reorient or relocate the receiving antenna. 　 Increase the separation between the equipment and receiver. 　 Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. 　 Consult the dealer or an experienced radio/TV technician for help. FCC Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body This device must be kept away from all persons by 20cm or more and installations using lessdistance, or installations using antennas with gain greater than that with which this wasCertified will require additional approvals.Antenna Specification:Type: External AntennaModel: EDA-1513-25GR2-B2Brand: MAG LAYERSGain: 2.0dBi
