Hi,

Thanks for your valuable advice, we will add it in the documentation.

Thank you Faye, invisible characters \r\n was the problem.

Would be worth adding a note about the invisible characters to the AT Instructions Set and AT Example Documentation.

Hi,

It is not a bug, it depends on your UART tool.

The "+++" has to be send through UART as a whole packet, if you just input it on keyboard, it may take a too long time as 3 "+" characters separated from each other.

Thanks for your interest in ESP8266 !

[Solved] UART-WiFi passthrough +++ does not quit transmission

2016-02-04T15:40:11+08:00

Hello

I have been unable to quit a UART-WiFi passthrough transmission by inputting "+++" as per the documentation. Instead +++ is transferred through the TCP connection and I receive an error from the server. The only way to get the ESP8266 out of this mode is to reset.

AT v0.52 and v0.60

AT+CIPMODE=1
AT+CIPSTART
AT+CIPSEND

I believe this is a bug.

Thanks
