correctly execute wps-pbc.</div><div>Moreover, it seems that wpa_supplicant, started as shown below, does not use the p2p configuration file that I put in /etc/ folder. </div><div>I say that because the Android devices I use to connect to wi-fi card on linux machine, do not notice the wi-fi card name.</div><div>The p2p configuration file contains the following
