When ESP8266 runs as TCP server, it will disconnect to the TCP client which did not communicate with ESP8266 till timeout. Command AT+CIPSTO can set the timeout.
Or could you try it with another module ?

I discover a bug while using my ESP8266 module. I upgraded the firmware version to ESP8266_NONOS_SDK_V1.4.0_15_09_18, and I wanted to create a custom Access Point with a TCP Server to send continous data, however I found that using a custom AP name when I try to send data, the connection fails. Here's my AT Commands and UART log.

OK
+CWMODE_DEF=2
OK
+CWSAP_DEF="WiFiModule","1234567890",5,3
OK
+CIPMUX=1
OK
+CIPSERVER=1,8888
OK
0,CONNECT
+CIPSEND=0,20
OK
>
Recv 20 bytes
0,CONNECT FAIL
SEND FAIL

As I'm using a 4 Mbit flash I cannot upgrade to the lastest firmware version, anyone knows how to solve this?
