I am not able to connect to Raspberry pi 3 using Wifi direct from android phone, What I tried is

Step 1: Changed the configuration in wpa_supplicant.conf and the contents are

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev



Step 2

Loaded configuration using

sudo wpa_supplicant -Dnl80211 -iwlan0 -c/etc/wpa_supplicant/p2p.conf -B

and the result is

Successfully initialized wpa_supplicant
ctrl_iface exists and seems to be in use - cannot override it
Delete '/var/run/wpa_supplicant/wlan0' manually if it is not used anymore
Failed to initialize control interface 'DIR=/var/run/wpa_supplicant GROUP=netdev'.
You may have another wpa_supplicant process already running or the file was
left by an unclean termination of wpa_supplicant in which case you will need
to manually remove this file before starting wpa_supplicant again.

nl80211: deinit ifname=wlan0 disabled_11b_rates=0

Step 3

Then started the wpa_cli

when running the command, p2p_find 60 it shows my android device and the android device can detect the PI device when a connection is initiated from the android, it will ask for the password/pin and the generated pin is displayed in the wpa_cli console. And after the pin is entered android phone shows invite send and nothing happens thereafter. when a status is issued in the wpa_cli terminal, it shows disconnected. How can I make the two devices connect? What changes should I make to make this working? Ant help will be appreciated. Please ask if you need more details.

It is a little bit difficult to examine what exactly goes wrong with your setup. wpa_supplicant claims that there may be already running an instance on interface wlan0. It could be that wpa_supplicant is already started on boot up. Before starting wpa_supplicant you can sudo killall wpa_supplicant to ensure that there is no other service running.

Then you try to make a connection with pin code method initiated from the android device. I suggest to use push button control (pbc) initiated from the RasPi. It is a bit simpler and you have better control over the handshake. How to do it you can look at Setting up Wifi direct (wifi p2p) and DHCP server.
