CIPCLOSE Issue

Postby SL!M » Thu Jan 29, 2015 12:05 am

Hi, there is a bug in the CIPCLOSE command in the latest update, to replicate:

1- set mode as AP and multi connection mode.
2- start a TCP server connection at port 80.
3- connect to the AP, and browse the the ESP ip: 192.168.4.1, you will see the HTTP request.
4- you will get an error when you try to disconnect(AT+CIPCLOSE=0), and the chip will reboot.

Hi,

Sorry that you have this problem , but we can not replicate it..
Our test steps are as follows:
"
AT+CWMODE=2

OK
AT+CWSAP="qwerty","123456789"

ERROR
AT+CWSAP="qwerty","123456789",5,3

OK
AT+CIPSERVER=1,80

ERROR
AT+CIPMUX=1

OK
AT+CIPSERVER=1,80

OK
0,CONNECT

Could you offer us more information, like UART output logs ?

The previous version didn't have this problem... and this problem happens ONLY on port 80. If you try to connect from any tcp client to port 80 and you send CIPCLOSE command you will get 0,CONNECT FAIL and the chip will reset.

Hi,

Thanks for your interest in ESP8266 !

The AT bin we released can works fine , baudrate is 115200 , AT commands end with CR LF

I tested the attached firmware and the bug is not fixed, still getting the same "0,CONNECT FAIL" and reboot after CIPCLOSE command... I'm sure its flashed correctly "AT version:0.22.b1.0"
anyone else tested the firmware?
Regards,
Ali
