hi
i have a question about esp8266 in server mode.
in this mode i need send data to spesial client.for example i used this at command:

AT+CIPSTART="TCP","192.168.1.10",8080

this command work until client connected to server (15 minute)but if client not connected to server this command can not work
in actual i need connect client to server when this client not connected to server and send data to spesial client.
anybody khnow about this problem?

Do you mean "send data to TCP client without TCP connection" ?

You can't do that .. TCP transmission need to create a TCP connection first ..
