UART-WIFI232-B2 User Manual
At this point, the Link indicator on the module changes from flashing once every 1 second to
flashing once every 2 seconds.

2.3 DATA TRANSMISSION TEST

The initial parameters for UART-WIFI232-B2 are as follows:
The default SSID is "Waveshare_xxxx" ("xxxx" represents the last four digits of the module's MAC

address).
The default encryption method is "open" and "none".

The default user serial parameters: 57600,8,1,None；

The default value of network parameters: TCP,Server,8899,10.10.100.254；

Local IP address: 10.10.100.254

We just need to follow the appropriate parameter settings for network communication, and
then bidirectional communication between the serial port and Wi-Fi can be achieved. The operation
steps are as follows:
Open the testing software "SSCOM.exe". Connect to the computer's COM5 (select the
appropriate port based on your situation). Choose the UART-WIFI232-B2 serial server's default baud
rate of 57600, and click "Open Port".
Open another instance of "SSCOM.exe". In the network settings section, choose TCP Client mode.
Enter the server IP address as 10.10.100.254, which is the default IP address of the module. Enter the
server port number as 8899, which is the default TCP port number the module listens on. Click
"Connect" to establish a TCP connection.
By now, we can test data transmission between the serial ports and network:
Data flow from the serial port to the network:
Computer serial port → UART-WIFI232-B2 serial port → WIFI/Ethernet of UART-WIFI232-B2 →

Computer network.
The data flow from the network to the serial port is:
Computer network -> UART-WIFI232-B2 WiFi/Ethernet -> UART-WIFI232-B2 serial port ->

Computer serial port. The specific demonstration is shown in the following figure:
