hostapd ne fonctionne pas depuis le shell adb

J'ai un LG G3 fonctionnant sous la version 5.1.1 et je peux activer le hotspot Wi-Fi portable dans le menu Paramètres. Je peux voir mon SSID Wi-Fi portable sur un autre appareil Android lorsqu'il est activé dans le menu Paramètres.

De plus, je peux confirmer que hostapd fonctionne avec un fichier de configuration généré automatiquement.

root@d851:/ # ps | grep hostapd
wifi      6841  302   10892  1280  c026dd60 b6ed98b4 S /system/bin/hostapd
root@d851:/ # cat /proc/6841/cmdline
/system/bin/hostapd -e /data/misc/wifi/entropy.bin /data/misc/wifi/hostapd.conf

Mon problème survient lorsque j'essaie de lancer hostapd manuellement via le shell adb en utilisant exactement les mêmes arguments que hostapd généré par le menu Paramètres. Je désactive le Wi-Fi manuellement via le menu Paramètres et je lance la commande suivante. Il semble que hostapd s'initialise avec succès mais le SSID Wi-Fi n'est jamais vu par les autres appareils.

root@d851:/ # /system/bin/hostapd -ddd -e /data/misc/wifi/entropy.bin /data/misc/wifi/hostapd.conf

Ce qui suit a été capturé à partir de logcat lorsque la commande ci-dessus a été émise.

Pourquoi l'exécution de hostapd avec exactement le même fichier de configuration via le shell adb ne crée pas de réseau Wi-Fi visible par les autres appareils ? SELinux est en mode permissif, j'ai donc exclu cette possibilité. Qu'est-ce qui peut bien m'échapper ? Y a-t-il un autre élément de configuration nécessaire pour activer le hotspot Wi-Fi portable à partir du shell adb ?

Toute aide est grandement appréciée.

Il y a en fait une autre étape avant de lancer la ligne de commande lors de l'exécution du fichier hostapd with conf, qui est de charger le firmware. Et c'est exactement pourquoi il y a cette impression :

D/hostapd ( 7885) : ctrl_iface non configuré !

Le firmware chargé va sonder une interface dans /data/misc/wifi/hostapd et c'est le socket du domaine Unix pour lequel le client hostapd peut communiquer avec le noyau.

Ajoutez quelques impressions de débogage dans SoftAPController.cpp et vous verrez l'image complète.
