HF-A11x V3.1 User Manual 1.4. Software Reference Design When HF-A11x modules boot up phase, the general user board MCU software flow chart will as following: Figure 11. User MCU Software Flow Chart HF-A11x modules provide two kinds of work mode and one configuration mode. Work mode is Transparent Transmission and Agreement Transmission. Configuration mode is through AT+instruction set to finish module setting and configuration.
PAGE 19
HF-A11x V3.1 User Manual High-Flying recommend when doing large amounts of data transmitting in transparent transmission mode, hardware flow control should be enabled, so as to fully ensure reliable data transmission. In the applications which doesn’t need flow control, users can simply leave RTS / CTS pin vacant. 1.4.2.

HF-A11x V3.1 User Manual 2. FUNCTIONAL DESCRIPTION 2.1. Wireless Networking HF-A11x module can be configured as both wireless STA and AP base on network type. Logically there are two interfaces in HF-A11x. One is for STA, and another is for AP. When HFA11x works as AP, other STA equipments are able to connect to wireless LAN via HF-A11x module. Wireless Networking with HF-A11x is very flexible. Following figure shows the functional architecture of HF-A11x module: Figure 15.
PAGE 25
HF-A11x V3.1 User Manual AP, this type of network is a loose structure, all the STAs in the network can communicate directly. As showing in the figure below, HF-A11x (1) can be treat as an AP, and HF-A11x (2), HF-A11x (3) and the laptop are STAs connected to HF-A11x (1). Meanwhile, all HF-A11x modules can connected to user device via UART interface. All HF-A11x modules can be operated and managed through the laptop. So it is convenient to O&M all HF-A11x modules.

HF-A11x Ethernet Interface Networking (As AP) Figure 19. HF-A11x Ethernet Interface Networking (As AP) For above networking, HF-A11x module works as AP and also the centre of this network.
PAGE 28
HF-A11x V3.1 User Manual For above networking, HF-A11x module works as STA（Firmware is Z-Version）,and module configured as bridge mode. When module connect to AP, all devices connected to module Ethernet interface will get assigned IP address from AP (For example: 192.168.1.101).For module works as bridge mode, it can be treated as a transparent device and PC1, PC2 can communicate without any limit. But in this networking, HF-A11x module needs assign a static LAN IP address (For example: 192.168.1.
