4.2. Framing mechanism
4.2.1. Time Trigger
When G786-G receives data from the UART, it continuously checks the interval of two adjacent bytes. If
the interval time is greater or equal to a certain "time threshold", then a frame is considered finished,
otherwise the data is received until greater or equal to the packet length byte set. This frame is sent to
the network as a TCP or UDP packet. The "time threshold" here is the time between packages. The
range of settable is 100ms~60000ms.Factory default: 100ms.
This parameter can be set by AT command, AT+UARTFT=<time>.
4.2.2. Length trigger
When G786-G receives data from the UART, it constantly checks the number of bytes received. If the
number of bytes received is equal to a certain "length threshold", a frame is considered to have ended,
otherwise the packaging time is waiting for the end. This frame is sent to the network as a TCP or UDP
packet. The "length threshold" here is the package length. The settable range is 100~1000.Factory
default 1000.
(Note: when using “command paAT command” function, the package length must be larger
than the “command paAT command”, otherwise AT command is invalid)
This parameter can be set by AT command, AT+UARTFL=<length>.
