Hi,all
I have set a tcp server.It waits tcp client to connect.If a tcp client connects, server send data(10 bytes) to client every 10ms by AT+CIPSEND.But I found after I sent the AT+CIPSEND and wait SEND OK response, it get 46ms, how can I improve the time, it doesn't work when i improve the USART baudrate.It seems the at software delay the data to send. And more, what's the difference between AT+CIPSEND and AT+CIPSENDBUF ? I don't get the information. Expect your answer, thanks a lot.
