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: 192.168.1.10) if module also needs communication with AP or
configuration through web page.

2.7. Work Mode
HF-A11x modules provide two kinds of work mode: Transparent transmission mode and
Agreement Transmission mode. Transparent transmission mode achieves a plug and play serial
data port, and reduces user complexity. Agreement Transmission mode can keep 100% accurate
data transmitting. User can configure dedicated work mode base on actual requirement, and
save the configuration information to the flash of HF-A11x, 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 pre-
configured parameters. Then all the data is transferred directly between serial interface and Wifi
interface without any interpreted.

Transparent transmission or Agreement Transmission mode
Transparent transmission demo as showing in the following figure, a HF-A11x module can be
taken as a virtual serial line when UART interface working in transparent transmission mode. And
user device will realize wireless data transmition almost without any changes.
