For left side USR-WIFI232-A/B/C module, configured as AP mode and use default SSID and IP
address, network protocol configured as TCP/Server mode, and protocol port ID: 8899.
For right side USR-WIFI232-A/B/C module, configured as STA mode and setting the same SSID
（ "USR-WIFI232-A/B_xxxx" for this example ） with left side USR-WIFI232-A/B/C module, enable
DHCP network and network protocol configured as TCP/Client mode, protocol port ID: 8899. Target IP
address part setting the same IP address with left side USR-WIFI232-A/B/C module ("10.10.100.254"
for this example).
When right side USR-WIFI232-A/B/C boot up, it will find wireless AP (SSID：USR-WIFI232-A/B_xxxx
for this example) and open TCP/Client network protocol to connect with left side module's TCP/Server.
All these operation will be automatic and after finished, the two user devices connected to USR-
WIFI232-A/B/C module through serial port can communicate each other and think the connection
between them is fully transparent.
