HF-A21-SMT Embedded WiFi Module User Manual 2. FUNCTIONAL DESCRIPTION 2.1. Wireless Networking HF-A21-SMT module can be configured as both wireless STA and AP base on network type. Logically there are two interfaces in HF-A21-SMT. One is for STA, and another is for AP. When HF-A21-SMT works as AP, other STA equipments are able to connect to wireless LAN via HFA21-SMT module. Wireless Networking with HF-A21-SMT is very flexible.
PAGE 22
HF-A21-SMT Embedded WiFi Module User Manual As showing in the figure below, HF-A21-SMT (1) can be treat as an AP, and HF-A21-SMT (2), HF-A21-SMT (3) and the laptop are STAs connected to HF-A21-SMT (1). Meanwhile, all HF-A21SMT modules can connected to user device via UART interface. All HF-A21-SMT modules can be operated and managed through the laptop. So it is convenient to O&M all HF-A21-SMT modules. Moreover, in such AP network structure, the whole coverage of a wireless network can be extended easily.
PAGE 23
HF-A21-SMT Embedded WiFi Module User Manual 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.
PAGE 24
HF-A21-SMT Embedded WiFi Module User Manual HF-A21-SMT‟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+FUARTTE=fash/normal, user can set the interval time: fast (10ms) and normal (50ms). This command is factory default setting command and AT+RELD can‟t change its value. 2.4.2.
PAGE 25
HF-A21-SMT Embedded WiFi Module User Manual For above networking, HF-A21-SMT module works as AP and also the centre of this network. All devices‟ IP address in this network shall use the same network segment with HF-A21-SMT and they can intercommunication with this method. 2.6.2. HF-A21-SMT Ethernet Interface Networking (As STA, N-Ver) Figure 19.

HF-A21-SMT Embedded WiFi Module User Manual complexity. User can save the configuration information to the flash of HF-A21-SMT, then module will go into the appointed work mode after power up. For a module which already finished parameters setting, it will try to connect a wireless network and server with these parameters after power up, and serial interface is also active with preconfigured parameters.
PAGE 27
HF-A21-SMT Embedded WiFi Module User Manual connected to the same wireless network. AT+instruction set configuration means user configure parameters through serial interface command. Refer to “AT+instruction set” chapter for more detail. Notes: High-Flying can customized the parameters setting as customer request and ship HF-A21-SMT modules with these parameters as factory default configuration. It will reduce user‟s module configuration time for mass production.
