Wi-Fi Parameter Setting
3.3.1.
Auto- Frequency Function
When device works as STA, it will adjust its wireless channel to keep the same channel with
associated AP and connect in.
When device works as AP and enable Auto-frequency function, then when device boot up, it will
select the best wireless channel based on surrounding environment.
3.3.2.
Security
The device supports multiple wireless encryption mechanisms, and enables to protect the
security
of user‟s data transmission, the mechanisms include:
WEP
WPA-PSK/TKIP
WPA-PSK/AES
WPA2-PSK/TKIP
WPA2-PSK/AES

Search Function for STA
When using web configuration of STA interface Setting Page, user can click "Search" button to
find the surrounding AP, and select a AP to connect.

Address Binding
The device supports the feature of binding the BSSID address of target network.
According to the provisions of 802.11 protocol, different wireless networks can have a same
network name (i.e. SSID / ESSID), but must correspond to a unique BSSID address (i.e. MAC
address). Illegal intruders can create a wireless network with the same SSID / ESSID, it will make
STAs in the network to join to the illegal AP, thereby and then network leakage happen.
Users can prevent STA from joining to illegal network by binding the BSSID address, to improve
wireless network security.

UART Free-Frame
The device support UART free-frame function. If user select open this function, device will check
the intervals between any two bytes when reciving UART data. If this interval time exceeds
