When HF-LPB works as AP, other STA equipments are able to connect to wireless LAN via HF-LPB module. Wireless Networking with HF-LPB 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-LPB Basic Wireless Network Structure 2.1.2. Wireless Network Based On AP+STA HF-LPB module support AP+STA network mode, means module support one AP interface and one STA interface at the same time, as following figure,

HF-LPB Concurrent Operation Networking 2.2. Work Mode : Transparent Transmission Mode HF-LPB 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: ¾ Wireless Network Parameters  Wireless Network Name（SSID）  Security Mode

UART Frame Scheme 2.3.1. UART Free-Frame HF-LPB 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-LPB will think it as the end of one frame and transfer this free-frame to WiFi port, or HF-LPB will receive UART data untill 1400 bytes, then transfer 1400 bytes frame to WiFi port. HF-LPB’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-LPB 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. ¾ Auto-frame trigger length: The fixed data length that module used to transmitting to the network. ¾ 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.

Multi-TCP Link Connection When HF-LPB module configured as TCP Server, it supports Multi-TCP link connection, and maximum eight TCP clients permit to connect to HF-LPB module. User can realize multi-TCP link connection at each work mode. Multi-TCP link connection will work as following structure: Upstream: All dates from different TCP connection or client will be transmitted to the serial port as a sequence. Downstream: All data from serial port (user) will be duplicate and broadcast to every TCP connection or client. Detailed multi-TCP link data transmition structure as following figure: Figure 14. Multi-TCP Link Data Transmition Structure 2.7. Power Save Scheme HF-LPB module can work at three modes based on different power save scheme:  Normal (Active/Sleep) Mode - AP Associated, WiFi ON/OFF based on internal control  Deep Sleep Mode - Non AP Associated, WiFi OFF  Standby Mode - Non AP Associated, WiFi Shut dwon Normal (Active/Sleep) Mode Normal mode support two work option: One is no DTIM related (Default mode), module will monitor the interval to Active/Sleep. The other is DTIM related mode, whcih allows the module to sync up with beacons sent from the AP which contains the DTIM (Delivery Traffic Indication Message). The DTIM indicates when broadcast and multicast data will be sent on the network. This property is configured on the AP (Default value is 1, which means DTIM= 100ms) and is typically configured as the number of beacons between each beacon with DTIM. Deep Sleep/Standby Mode allows the WiFi circuitry to be “OFF” status or powered down, which results in the lower/lowest sleep current, but at the expense of longer wake up times. This is due to
HF-LPB Low Power WiFi Module User Manual Shanghai High-Flying Electronics Technology Co., Ltd www.hi-flying.com - 24 - the module associating with the access point every time when it wakes up. The intent of this option is to allow for longer sleep times. The Difference between deelp sleep and standby mode as follows: Table 6 Difference Between Deelp Sleep And Standby Mode Status Wake Up Method Wi-Fi MCU Current UART GPIO Timeout AT CommondDeep Sleep OFF ON ~2mA ON Yes Yes Yes Standby OFF OFF <2uA OFF Yes Yes No Notes: For GPIO wake up, if trigger time <1s, then only wake up MCU. Following typical measurement parameters can be used for select suitable power save scheme based on the real application case: Table 7 Power Consumption with Different Power Save Mode WiFi Mode Condition Average Current Peak Current Standby WiFi Shutdown ~2uA < 10uA Deep Sleep WiFi OFF ~2mA < 10mA Normal (Active/Sleep)WiFi ON - AP Connected DTIM = 100ms 5.5~7mA < 220mA Normal (Active/Sleep)WiFi ON – AP Connected DTIM = 500ms 3.5mA < 220mA Normal (Active/Sleep)WiFi ON – AP Connected DTIM = 1000ms 2.8mA < 220mA In addition, for deep sleep/standby mode, module provides three wakes up options, user can select one or whole as the module wake up option. Refer to AT Instruction (Power Management Instruction Set) for more detailed setting.  Pin Wake Up  UART Wake Up  Timeout Wake Up Pin Wake Up Option allows an external microcontroller to determine when HF-LPB should sleep and when it should wake by controlling the “Sleep_RQ” and “Sleep_ON” pin. at the deep sleep/standby mode, user can de-assert this pin low “0”, after 1’s assert to high ”1” to put the module to wake up the module. If user doesn't use pin sleep function, can leave this pin open. UART Wake Up Option. HF-LPB can use AT command to put module into normal/sleep mode. When module works at deep sleep or standby mode, user can use ”AT+MSLP =normal” to wake up module. Timeout Wake Up Option allows the sleep timeout period to be configured through the use of AT Instruction.In this option, the module will exit sleep based on the <Timeout> AT Instruction parameters
