RS232/485 TO WIFI POE ETH (B) User Manual
Figure Webpage Sets Serial Parameters
AT Command Settings
If you need to change the WiFi serial server baud rate to 115200bps, use the following command:
AT+UART=115200,8,1,None,NFC
6.4.2 UART FREE-FRAME MODE
The default interval time for two bytes in the WiFi serial server is 10ms, which means that when
the interval time is greater than 10ms, a frame is considered complete.
Using the example of sending data from a serial device to a serial server, let me explain the process of
free-frame assembling in a WiFi serial server:
Assuming that n is the interval for free-frame assembling, measured in milliseconds, where T1 > n, T2
< n, T3 < n, T4 < n, T5 < n, T6 > n, then Byte1 to Byte5 are treated as a single frame of data, as
illustrated
