2.3. UART Frame Scheme
2.3.1. UART Free-Frame
USR-WIFI232-T support UART free-frame function. If user select open this
function, module will check the intervals between any two bytes when
receiving UART data. If this interval time exceeds defined value (50ms
default), USR-WIFI232-T will think it as the end of one frame and transfer
this free-frame to WiFi port, or USR-WIFI232-T will receive UART data until
1000 bytes, then transfer 1000 bytes frame to WiFi port.
USR-WIFI232-T’s default interval time is 50ms. User can also set this
interval to fast (10ms) through AT command. But user have to consider if
user MCU can send UART data with 10ms interval ,or the UART data may be
divide as fragment.
Through AT command: AT+UARTTE=fash/normal, user can set the interval time:
fast (10ms) and normal (50ms).
2.3.2. UART Auto-Frame
USR-WIFI232-T support UART auto-frame function. If user select open this
function and setting auto-frame trigger length and auto-frame trigger time
parameters, then module will auto framing the data which received from UART
port and transmitting to the network as pre-defined data structure.

Auto-frame trigger length : The fixed data length that module used to
transmitting to the network.
