Sorry for the inconvenience.

In UART-TCP passthrough mode, if the TCP connection broke, the ESP8266 will re-connect it automatically. If the MCU continually send data through UART, the data will be lost.

All works well, but if for some reason the connection is lost, the connection is re-established automatically (I can see multiple attempts in Wireshark from the device). After the connection is re-established, there is no way of my application (from the 8266 side) of known this has happened. The way I have written the server application , this cant be allowed as there has to be a login sequence. I wasnt sure if the timeout parameter in the at+cipstart is used for this, but I get an error if I add it. Below is what I tried , I added the last two parameters but got error (I replaced my ip to xxx.xxx.xxx.xxx for here only)

AT+CIPSTART="TCP","xxx.xxx.xxx.xxx",1963,1964,0


at+gmr returns :
AT version:0.60.0.0(Jan 29 2016 15:10:17)
SDK version:1.5.2(80914727)
compile time:Jan 29 2016 19:07:08

Thanks
Neil
