Reconnect to a paired WiFi Direct device

I’d like to reconnect to a paired Wizfi250 with my phone.
When I paired a Wizfi250 the phone generates a group for this device.
When I turned off and on the Wifi on my phone, I couldn’t connect to the Wizfi250.
I must type AT+WP2P_START command again.
The phone pairing again the Wizfi250 and create a new group for it.
How can I reconnect to a paired Wizfi250 without pairing procedure?

As you tested it, you should manually reconnect it using at command.
Sorry for that.
