Hi,

So sorry that there is no auto reconncet.

You could call espconn_connect in espconn_disconnect_callback(normal disconnect) or espconn_reconnect_callback(abnormal disconnect) to reconnect TCP server.

Thanks for your interest in ESP8266 !

this would require a custom firmware compilation (based on 0.9.5) rt ?

Yes, do you mean using AT commands ?

Call AT+CIPSTART to create a TCP connection again, if message about disconnection is received.

[nccchirag]

with AT commands, AT+CIPSTART would have to be issued by the MCU
can the SDK take care of the auto re-connection ... ?
eg. firmware would autoconnect to wireless router if it is rebooted .. but the TCP connection would have to be manually initiated from the MCU via AT command
