I'm trying to connect android and Raspberry PI using WIFI Direct. It is connected successfully but it's the disconnect after 10 seconds automatically.

My configuration file is as per below

/etc/wpa_supplicant/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant

Is your IP address 169.254.68.39 appropriate with wpa_cli -i p2p-wlan0-0 status?

From your ifconfig output, the IPv4 addressing appears to be missing for p2p-wlan0-0 (the P2P-GO persistent group). Check your systemd-networkd configuration (if you are using this method) or your dnsmasq configuration, so that an IP address is appropriately given to this virtual interface. In general, this is a typical problem producing fast disconnection just after the P2P session is successfully activated.

Example of systemd-networkd configuration in a file under /etc/systemd/network/:

[Match]
Name=p2p-wlan0-*
[Network]
Address=192.168.4.1/24
DHCPServer=yes

Alternative example of /etc/dnsmasq.conf:

interface=p2p-wlan0-*
dhcp-range=192.168.4.50,192.168.4.199,12h
dhcp-option=3

Notice also that you are using a 4-digit PIN. By default, 8-digit PINs are configured.

I do not understand the setup in /etc/wpa_supplicant/wpa_supplicant.conf. For me it looks like a mix up of an autonomous group owner with a dynamic negotiated group owner. Then with

p2p_listen_reg_class=81
p2p_listen_channel=1
p2p_oper_reg_class=81
p2p_oper_channel=1

you restricted the communication to use only channel 1 rather than 1, 6 and 11. This is only for debugging. You should not use it for normal operation. I suggest to try to Connect Android smartphone with Wi-Fi Direct to a Raspberry Pi.

  • @ino thank you for comment. I follow the steps as per the link mention by you, When I connect it's getting connected but after some time it's automatically getting disconnected.

  • @bhavinpanara What connection method do you use? Have you tried default pin code authentication? What messages does wpa_supplicant give you why it stops the connection?

  • I have tried with the default pin code authentication method also but the observation is the same. Currently, i have put log of Connect with the pin code method, with pin set by the smartphone method.
