4.5.1 Auto- Frequency Function
When module works as STA, WIFI232 will adjust its wireless channel to keep the same channel
with associated AP and connect in.
When module works as AP and WIFI232 enable Auto-frequency function, then when module boot
up, it will select the best wireless channel based on surrounding environment.

4.5.4 Address Binding
WIFI232 module 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.
