Dear HostAP hackers, I enable WiFi P2P connections to a Linux host via wpa_supplicant with a wpa-client I devised. After connect by a Nexus 7 Android tablet and then disconnect, the Linux host disappears from the tablet's list of P2P devices, and only reappears after rebooting the host. Neither reissuing a p2p_ext_listen, nor restarting wpa_supplicant on the P2P interface brings it back. I hope someone knows the incantation to re-materialize it :-) (Pls preserve CC line in responses, as I receive the digest.) wpa_supplicant 2.5 with -i p2p0 -D nl80211 -c /etc/wpa_supplicant/p2p0.conf kernel 4.7.2 (mainline) distro Arch Linux ARM cpu TI AM3703 radio Marvell sd8787 p2p0.conf: ctrl_interface=/run/wpa_supplicant ap_scan=1 device_name=mwifiex-p2p-device device_type=1-0050F204-1 p2p_listen_reg_class=81 p2p_listen_channel=1 p2p_oper_reg_class=81 p2p_oper_channel=1 p2p_no_group_iface=1 p2p_go_intent=15 my-wpa-client source: https://github.com/networkimprov/p2p-host/blob/master/main.c my-wpa-client log: PDS: is P2P_EVENT_PROV_DISC_SHOW_PIN req: is a msg to wpa_supplicant $ sudo p2p-host/p2phostd /run/wpa_supplicant/p2p0 75 1500 11111111 req: P2P_EXT_LISTEN 75 1500 : OK ###: <3>P2P-DEVICE-FOUND ae:22:0b:48:49:61 p2p_dev_addr=ae:22:0b:48:49:61 pri_dev_type=10-0050F204-5 name='Android_7326' config_methods=0x188 dev_capab=0x25 group_capab=0x0 new=1 PDS: ae:22:0b:48:49:61 34633045 p2p_dev_addr=ae:22:0b:48:49:61 pri_dev_type=10-0050F204-5 name='Android_7326' config_methods=0x188 dev_capab=0x25 group_capab=0x0 req: P2P_CONNECT ae:22:0b:48:49:61 11111111 display go_intent=0 : OK PDS: ae:22:0b:48:49:61 61911116 p2p_dev_addr=ae:22:0b:48:49:61 pri_dev_type=10-0050F204-5 name='Android_7326' config_methods=0x188 dev_capab=0x25 group_capab=0x0 req: P2P_CONNECT ae:22:0b:48:49:61 11111111 display go_intent=0 : OK ###: <3>P2P-GO-NEG-SUCCESS role=client freq=2417 ht40=0 peer_dev=ae:22:0b:48:49:61 peer_iface=ae:22:0b:48:c9:61 wps_method=Display ###: <3>CTRL-EVENT-SCAN-STARTED ###: <3>CTRL-EVENT-BSS-ADDED 0 20:4e:7f:92:63:d6 ###: <3>CTRL-EVENT-SCAN-RESULTS ###: <3>WPS-AP-AVAILABLE ###: <3>CTRL-EVENT-SCAN-STARTED ###: <3>CTRL-EVENT-SCAN-RESULTS ###: <3>WPS-AP-AVAILABLE ###: <3>CTRL-EVENT-SCAN-STARTED ###: <3>CTRL-EVENT-BSS-ADDED 1 ae:22:0b:48:c9:61 ###: <3>CTRL-EVENT-SCAN-RESULTS ###: <3>WPS-AP-AVAILABLE-AUTH ###: <3>Trying to associate with ae:22:0b:48:c9:61 (SSID='DIRECT-4B-Android_7326' freq=2417 MHz) ###: <3>Associated with ae:22:0b:48:c9:61 ###: <3>CTRL-EVENT-EAP-STARTED EAP authentication started ###: <3>CTRL-EVENT-EAP-STATUS status='started' parameter='' ###: <3>CTRL-EVENT-EAP-PROPOSED-METHOD vendor=14122 method=1 ###: <3>CTRL-EVENT-EAP-STATUS status='accept proposed method' parameter='WSC' ###: <3>CTRL-EVENT-EAP-METHOD EAP vendor 14122 method 1 (WSC) selected ###: <3>WPS-CRED-RECEIVED ###: <3>WPS-SUCCESS ###: <3>P2P-GROUP-FORMATION-SUCCESS ###: <3>CTRL-EVENT-EAP-STATUS status='completion' parameter='failure' ###: <3>CTRL-EVENT-EAP-FAILURE EAP authentication failed ###: <3>CTRL-EVENT-DISCONNECTED bssid=ae:22:0b:48:c9:61 reason=3 locally_generated=1 ###: <3>Trying to associate with ae:22:0b:48:c9:61 (SSID='DIRECT-4B-Android_7326' freq=2417 MHz) ###: <3>Associated with ae:22:0b:48:c9:61 ###: <3>WPA: Key negotiation completed with ae:22:0b:48:c9:61 [PTK=CCMP GTK=CCMP] ###: <3>CTRL-EVENT-CONNECTED - Connection to ae:22:0b:48:c9:61 completed [id=0 id_str=] ###: <3>P2P-GROUP-STARTED p2p0 client ssid="DIRECT-4B-Android_7326" freq=2417 psk=f11ba4239bf55bace903536d26f2118404587b0c76931454265a43dc3c7e3622 go_dev_addr=ae:22:0b:48:49:61 [PERSISTENT] ###: <3>CTRL-EVENT-BSS-REMOVED 0 20:4e:7f:92:63:d6 ###: <3>CTRL-EVENT-DISCONNECTED bssid=ae:22:0b:48:c9:61 reason=3 ###: <3>CTRL-EVENT-DISCONNECTED bssid=ae:22:0b:48:c9:61 reason=3 locally_generated=1 ###: <3>P2P-GROUP-REMOVED p2p0 client reason=GO_ENDING_SESSION ###: <3>CTRL-EVENT-BSS-REMOVED 1 ae:22:0b:48:c9:61 ###: <3>P2P-DEVICE-LOST p2p_dev_addr=ae:22:0b:48:49:61 ^C [after many attempts to re-locate this host] _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
