Problem Description

I have 2 devices use esp8266 (ESP-12F module). Both of them running same firmware and connect to same wi-fi AP. The application is simple touch switch: button, relay, connect wifi, connect mqtt and get control command from mobie app. Two device running same firmware, working at the same time and monitoring same time on terminal.

The problem is that one of my device do not connect wi-fi AP and do not get IP address but other one work well. I will attach log message bellow. The Red-boundary (I will call as Red) is log message of device got error. The Green-boundary(I will call as Green) is log message of device that work normally, connected wi-fi, get IP address.

I had check device list on router's web manager and saw that both device was allocated IP address. But the "Red" do not get event wi-fi connected like "Green".
