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

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. – bhvn Oct 05 '20 at 08:47
  • @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? – Ingo Oct 05 '20 at 08:56
  • 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. – bhvn Oct 05 '20 at 09:35
  • @bhavinpanara What Android version do you use on the smartphone? – Ingo Oct 05 '20 at 09:39
  • Android version: 10 QP1A.190711.020 – bhvn Oct 05 '20 at 12:28
  • I have also tested with Android version: 8.1.0 and observation are the same that it's disconnected automatically after connected. And i also check android to the android connection between 8.1.0 and 10 QP1A.190711.020 it's working perfectly. Thank you for your time! – bhvn Oct 05 '20 at 13:20
  • @ ingo Your guidance into this problem is really help full to me. If you have any idea that I have to try out please share it. Thank you. – bhvn Oct 06 '20 at 07:46
  • @bhavinpanara Do you start the connection from the beginning? Do you run wpa_supplicant in the foreground with the help of screen? Does the frequencies match? Does the P2P-PROV-DISC-*-REQ * message match the pin authentication method? Do you have invited an other Available device? – Ingo Oct 06 '20 at 07:58
  • @ ingo(1)Yes, I have start connection from the beginning. (2) Yes, I have run wpa_supplicant in the foreground with the help of two screen logs are updated in the question section (3) Frequency match, not sure but from the log found P2P-GROUP-STARTED p2p-wlan0-0 GO ssid="DIRECT-Q0" freq=2437 go_dev_addr=2e:2c:5b:36:09:20 (4) Yes It's match. P2P-PROV-DISC-SHOW-PIN fe:31:25:c7:57:0b 22929280 p2p_dev_addr=fe:31:25:c7:57:0b pri_dev_type=10-0050F204-5 name='Redmi 9i' config_methods=0x188 dev_capab=0x25 group_capab=0x0 (5) Not invite any other device. – bhvn Oct 06 '20 at 09:09
  • @ ingo did you found anything wrong? Thank you for your time!! – bhvn Oct 06 '20 at 09:57
  • I*m out of ideas now. The problem is that I can't reproduce it. It's working for me. I cannot look for an error that isn't present. You can try to start wpa_supplicant with the additional option -d, means debug. But this gives you a huge amount of additional messages that may more confuse than help. You can try to redirect the output into a file to examine it later, e.g. sudo /sbin/wpa_supplicant -c/etc/wpa_supplicant/wpa_supplicant-wlan0.conf -Dnl80211 -iwlan0 -d > debug.out. – Ingo Oct 06 '20 at 17:04
  • I have started wpa_supplicant as per your suggested way. I found log nl80211: Drv Event 20 (NL80211_CMD_DEL_STATION) received for p2p-wlan0-0 This command NL80211_CMD_DEL_STATION is responsible for delete connection. but I'm finding it's the reason why this NL80211_CMD_DEL_STATION command is executing in wpa_supplicant. I have also edited the log in the question section. if you know the reasion please guide me into that. Thank you for support !! – bhvn Oct 07 '20 at 06:27
  • @ ingo One more observation is that I can create successful communication between two Linux machines using wifi direct. My ultimate goal was to establish communication between Windows 10 and Linux. Here [ https://answers.microsoft.com/en-us/windows/forum/windows_10-hardware/how-to-implement-wifi-direct-between-windows10-and/4ca49250-38a0-4327-9f39-47284a9af800?tm=1585548436542 ]. In windows to Linux have the same observation as android to Linux. And android to windows is working. So something I'm missing on the Linux side. – bhvn Oct 07 '20 at 12:49
  • This does not look like a dynamic negotiated group, because p2p_connect is not used. A number of persistent groups are indeed created in the configuration file with different bssid, possibly due to the randomized address issue each time wpa_supplicant is restarted. – ircama Feb 24 '21 at 20:26

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.
