Uart Auto-Frame; Network Setting - Waveshare WIFI232-B2 User Manual

WIFI232-B2 User Manual
WIFI232's default interval time is 500ms. User can also set this interval to fast
(10ms) through AT command. But user have to consider that if user MCU can send
UART data with 10ms interval, or the UART data may be divide as fragment.
Through AT command: AT+FUARTTE=fast/normal, user can set the interval time:
fast (10ms) and normal (50ms). This command is factory default setting command and
AT_RELA cannot change its value.

4.6.2 UART Auto-Frame

WIFI232 support UART auto-frame function. If user open this function and setting
auto-frame trigger length and auto-frame trigger time parameters, then module will
auto frame 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.
 Auto-Frame trigger time: After the trigger time, if UART port received data
cannot reach auto-frame trigger length, then module will transmitting available data to
the network and bypass the auto-frame trigger length condition.
Auto-Frame trigger time is calculated when the module receive first byte from UART
port as below:
Detailed UART auto-frame function can refer to AT+ instruction set
"UARTF/UARTFT/UARTFL" introduction.
