ESP8266_NONOS_SDK_V1.4.0_15_09_18 TCP Server Bug

[cesar.guevara]

Hi,

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?

Hi,

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 ?
