You are right, the situation was that the module sometimes connect automatically with my other module, this is the reason for the eventual error.

Thank you very much Espressif_Faye.

Here is our latest AT firmware http://bbs.espressif.com/viewtopic.php?f=5&t=554

Download and unzip the attachment, in \esp_iot_sdk\document , please refer to "4B-ESP8266__AT Command Examples"

You need to use command AT+CWJAP="SSID","password" to connect to router first.

Thanks for your interest in ESP8266 !

The problem is that I try to connect two ESP8266, one operate in Station mode and the second in AP mode. The problem is that, sometimes the connection is made, also I can send and receive data, however, it is lost and I cannot connect again, I'll describe the procedure:
