TCP IP & UART together


#1

Hello.

My module is 1306B

after openning TCP IP socket in client mode,
my program svitch the UART1 to the DATA Mode
uart work on 3 line mode (rx, tx, gnd).

module send all incoming UART data to TCP IP Socket

i now that size of the incoming packet is approximately 70 byte
but uart always receive 16 or 26 byte(frequently 26).

Did someone meet similar difficulties?

What do you mean, “incoming”?
Data can “come in” on both the UART and the TCP/IP Socket - which one are you talking about? :unamused:

That sounds like perfectly normal UART behaviour to me!
Why do you consider that to be a “problem”?

Data --> | Uart | -> Application ->
TCP IP Socket (Client Mode) | -> TCP Server
