Wireless Networking HF-LPB200 module can be configured as both wireless STA and AP base on network type. Logically there are two interfaces in HF-LPB200. One is for STA, and another is for AP. When HF-LPB200 works as AP, other STA equipments are able to connect to wireless LAN via HF-LPB200 module. Wireless Networking with HF-LPB200 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. 3.1.1. 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 11. HF-LPB200 Basic Wireless Network Structure 3.1.2. Wireless Network Based On AP+STA HF-LPB200 module support AP+STA network mode, means module support one AP interface and one STA interface at the same time, as following figure,
HF-LPB200 Low Power WiFi Module User Manual Shanghai High-Flying Electronics Technology Co., Ltd www.hi-flying.com - 20 - Figure 12. 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. 3.1.3. Wi-Fi Direct Network Wi-Fi Direct standard permits the wireless connection without AP router. Like blue tooth, this standard use point to point interconnection and all devices connect each other and transmit data withour router. HF-LPB200 module support following Wi-Fi Direct networking:  1:1 P2P Networking;  1:N P2P Networking (TBD); Figure 13. HF-LPB200 1:1 P2P Networking

Work Mode : Transparent Transmission Mode HF-LPB200 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  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
HF-LPB200 Low Power WiFi Module User Manual Shanghai High-Flying Electronics Technology Co., Ltd www.hi-flying.com - 22 - 3.3. UART Frame Scheme HF-LPB200 support UART free-frame function. Module will check the intervals between any two bytes when reciving UART data. If this interval time exceeds defined value (50ms default), HF-LPB200 will think it as the end of one frame and transfer this free-frame to WiFi port, or HF-LPB200 will receive UART data untill 1400 bytes, then transfer 1400 bytes frame to WiFi port. HF-LPB200‟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). 3.4. 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-LPB200 module supports following:  WEP  WPA-PSK/TKIP  WPA-PSK/AES  WPA2-PSK/TKIP  WPA2-PSK/AES 3.5. Multi-TCP Link Connection When HF-LPB200 module configured as TCP Server, it supports Multi-TCP link connection, and maximum eight TCP clients permit to connect to HF-LPB200 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:
HF-LPB200 Low Power WiFi Module User Manual Shanghai High-Flying Electronics Technology Co., Ltd www.hi-flying.com - 23 - Figure 15. Multi-TCP Link Data Transmition Structure 3.6. Power Save Scheme HF-LPB200 module can work at three modes based on different power save scheme:  Normal Mode (Active/Sleep) - AP Associated, Wi-Fi ON/OFF based on internal control  Wi-Fi Wakeup Mode (Standby) - AP Associated, MCU OFF, Wi-Fi wakeup  Deep Sleep Mode (Shutdown) - Non AP Associated, Wi-Fi Shut dwon, MCU Sleep Pin/Timer Wakeup Normal Mode (Active/Sleep) Normal mode means Wi-Fi circuitry works at IEEE PS mode and MCU circuitry work at normal mode. That‟s the default working mode for HF-LPB200 to communication with outside and no data transceiving latency. Wi-Fi Wakeup Mode (Standby) allows the MCU circuitry to be powered down and still keep Wi-Fi AP associated, which save more power compared with normal mode and module can be wake up through Wi-Fi at network server side. Deep Sleep Mode (Shutdown) allows the Wi-Fi circuitry and MCU circuitry to be powered down, which results in the lowest sleep current, but at the expense of longer wake up times. This is due to 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. Deep sleep mode can trigger “Sleep_RQ” pin to go in. The Difference between Wi-Fi Wakeup and Deep Sleep mode as follows: Table 6 Difference between Wi-Fi Wakeup Mode and Standb Deep Sleep Mode Module Status Wake Up Method Wi-Fi MCU Current UART GPIO Timeout AT Com. Wi-Fi Wi-Fi Wakeup ON OFF <10mA OFF Yes Yes No Yes Deep Sleep OFF OFF 1mA OFF Yes Yes No No Following typical measurement parameters can be used for select suitable power save scheme based on the real application case:
HF-LPB200 Low Power WiFi Module User Manual Shanghai High-Flying Electronics Technology Co., Ltd www.hi-flying.com - 24 - Table 7 Power Consumption with Different Power Save Mode WiFi Mode Condition Average Current Peak Current Deep Sleep Wi-Fi/MCU Shutdown < 100uA < 100uA Wi-Fi Wakeup MCU Shundown ~10mA < 200mA Normal (Active/Sleep) WiFi ON - AP Associated DTIM = 100ms, No Data ~21mA < 250mA Normal (Active/Sleep) WiFi ON - AP No-Assoiated DTIM = 100ms, No Data ~27mA < 250mA Normal (Active/Sleep) WiFi ON – AP Connected DTIM = 100ms, Date:1KB/s ~50mA < 250mA In addition, for Wi-Fi Wakeup/Deep Sleep 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 (Sleep_RQ) Wake Up  Timeout Wake Up  Wi-Fi Wake Up Pin Wake Up Option allows an external microcontroller to determine when HF-LPB200 should sleep and when it should wake by controlling the “Sleep_RQ” and “Sleep_ON” pin. at the Wi-Fi wakeup mode/Deep Sleep 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. 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 Wi-Fi Wake Up Option only applicatable for Wi-Fi Wakeup mode, which provide the flexibility for network server or user to control and manage the Wi-Fi device to go into power save mode, but still keep the Wi-Fi link associated, Refer to AT Instruction to know more about the WiFi wakeup command. 3.7. Parameters Configuration HF-LPB200 module supports two methods to configuration parameters: Web Accessing and AT+instruction set.
