Here is a guide, 4B-ESP8266__AT Command Examples.

Please refer to Chapter 4 in the documentation for UART - WiFi passthrough mode.

Here is my UART Stream.....

AT+CIPSTART="TCP","192.168.1.102",80

AT+CIPSTART="TCP","192.168.1.102",80

AT+CIPMODE?

AT+CIPMODE=1

AT+CIPSTART="TCP","192.168.1.102",80

CONNECT

OK
AT+CIPSEND=16

IPMODE=1

If +CIPMODE = 0, I can send data ....... MCU UART->ESP8266->network->Server
and it sends data back...

But, if I change CIPMODE to 1...... it won't let me send data from the MCU out.....

Isn't this backwards from the AT+CIPMODE instructions documented ?

You have set the ESP8266 enter UART <-> WiFi passthrough mode.

Remote <-network-> ESP8266 <-UART-> MCU

Data received from the network will be sent to your MCU by UART.
And data recerved from MCU through UART will be sent to remote device through network.

Thanks for your interest in ESP8266 !

if I send this to the ESP and set it to transmit

Code:

AT+CWMODE_CUR=2\r\n
AT+CIPSTART=\"TCP\",\"192.168.10.11\",900\r\n
AT+CIPMODE=1\r\n
AT+CIPSEND\r\n


will it still be able to receive data and send them out through UART to my MCU?

Thanks for your advice.
