What does mean those state transitions? I mean
state: 0 -> 2 (b0)
state: 2 -> 3 (0)
state: 3 -> 0 (4)
On other hand, it succesfully connected to many other android phones, for example Philips Xenium W6610.
Here is the log with succes connection to some ap:

So, take a look at several last rows. We can see another series of state transitions:
state: 0 -> 2 (b0)
state: 2 -> 3 (0)
state: 3 -> 5 (10)
The difference is only in last transition: at first example it rreturns to state 5 [3 -> 0 (4)], an on second one it returns to state 5 [3 -> 5 (10)]
So, the question is: what's happend that prevent ESP8266 to connect to "Xperia E4g_1bd3"?
Many thanks.
