How about the latest AT firmware on Espressif Official BBS

- Mon Feb 09, 2015 10:12 am #9328 You're setting up your TCP server but not the client. You need to specify where you want the ESP to connect to, the port and whether it's TCP/UDP traffic. For example:

Code: Select allAT+CIPSTART=1,"TCP","192.168.0.4",3912

Once that's done, try your CIPSEND command again and be sure to listen on this address on the other computer. Just like Athena suggested though, always try using the latest firmware. Unless you're tinkering with custom built one.
