WiFi Direct WPA2 settings

How can I setting the WPA2 password on WiFi Direct mode?

No, WizFi250 doesn’t support that.

OK. It’s no problem - because we can send encrypted packets via P2P link.
But other question:
How can I check the MAC address of the connected device?
(AT+WSTAT get back just the WizFi250MAC address.)

There is no way to find the Mac of the peer.
