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 below:
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. This interval time can be
