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.
User can prevent STA from joining to illegal network by binding the BSSID address,
to improve wireless network security.

UART Frame Scheme
4.6.1
UAER Free-Frame
WIFI232 support UART free-frame function. If user select open this function,
module will check the intervals between any two bytes when receiving UART data. If this
interval time exceeds defined value (50ms default), WIFI232 will think it as the end of
one frame and transfer this free-frame to WIFI port, or WIFI232 will receive UART data
until 4K bytes, then transfer 4KB frame to WIFI port.
