Mode AP avec wpa_supplicant

Question

J'essaie de configurer l'adaptateur Wifi (Qualcomm Atheros Sparrow 802.11ad) dans Ubuntu 16.10 avec Kernel v4.8 pour qu'il fonctionne en mode AP en utilisant wpa_supplicant v2.4. Je fais les étapes suivantes:

Je crée un fichier de configuration dans /etc/wpa_supplicant.conf avec la configuration suivante extraite de site web wil621 :
```
ap_scan=2 network={ frequency=60480 ssid="the_ssid_string" mode=2 key_mgmt=NONE } 
```
J'exécute la commande suivante pour initialiser wpa_supplicant:

wpa_supplicant -Dnl80211 -iwlp2s0 -c/etc/wpa_supplicant.conf

Je reçois une erreur indiquant que le wpa_supplicant n'est pas en mesure d'analyser ap_scan alors j'omets cette ligne pour le test, puis j'exécute à nouveau et j'obtiens la nouvelle erreur suivante:
```
Successfully initialized wpa_supplicant Failed to create interface p2p-dev-wlp2s0: -22 (Invalid argument) nl80211: Failed to create a P2P Device interface p2p-dev-wlp2s0 P2P: Failed to enable P2P Device interface wlp2s0: Failed to start AP functionality 
```

Une idée comment résoudre ce problème?

Voici la sortie de débogage détaillée:

J'ai trouvé le problème, une autre instance de wpa_supplicant était en cours d'exécution et bloquait ma demande. J'ai tué le processus et j'ai pu exécuter l'adaptateur sans fil en mode point d'accès.
