yes.

Now I came home and let try to use it, my mobile connects to AP
and I can use that.

But.

I closed connection and try to reconnect, and mobile can't see the
SSID. I have restarted hostapd and device can see again...
In log there're just these lines, no more:

Please help me, I'm at lost :(

Is my config right?
