5.4.2 WIRED NETWORKING APPLICATION (APWAN)

The UART-WIFI232-B2 serial server is used as AP, Ethernet port is set as WAN port, and it is
connected to the route that can access the external network, so the DHCP server function is enabled.
The serial server is used as a secondary router, and a PC or other smart handheld device can access
the Internet by connecting to the serial server AP. At this time, the default AP of the serial port server
is usually UART-WIFI232-B2_xxxx, which has no encryption and can be set through web pages or at
commands.
After the serial server is connected to the AP, it obtains the IP address from the AP (as shown in
Figure 192.168.1.10). The serial server itself forms a subnet (default is 10.10.100.254), and the
devices on the Ethernet port are assigned addresses by the serial server (as shown in Figure
10.10.100.100, as shown below):
