AT+CIPSEND length problem

[lukasz_micromex]

Hi,

I have a problem with sending data using AT+CIPSEND command. My esp works as server (kind of web server) and when I get data, I want to send response 30 - 100 kilo bytes of data. When length of data is 256 it works well but SEND OK answer comes after 220ms. It is too long to me, sending 100kb takes to long. If I want to send 1024 or 2048 length of data I never gets SEND OK so I am waiting 10s, 15s, 30s then if I try send something more I always get busy. Is there any solution to send more data in shortest time?

Hi,

How about UART-WiFi pass through mode, transparent transmission ?
It do not have send OK message, can transmit faster.

Can you give me an example how to send data in pass through mode, transparent transmission when ESP works as server and multiconnection mode? How about sending 2048 bytes and no response from ESP?

Hi,

AT firmware does not support UART-WiFi passthrough in TCP server mode by default.
But here is an example of UART-WiFi passthrough in TCP server mode you can refer to http://bbs.espressif.com/viewtopic.php?f=31&t=1393.
Thanks for your interest in ESP8266 !
