My phone's wifi chip is BCM4356 I create a visual card use this command: iw dev wlan0 interface add wlan0_ap type __ap

ifconfig -a

wlan0_ap: flags=4098<BROADCAST,MULTICAST> mtu 1500 ether 04:e2:b9:17:18:72 txqueuelen 1000 (Ethernet) RX packets 0 bytes 0 (0.0 B) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 0 bytes 0 (0.0 B) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

create_ap wlan0_ap wlan0 myap 12345678

got this error messeage: Failed to get phy interface ERROR: Your adapter does not support AP (master) mode

but iw list show it support ap: iw list

Wiphy phy0 max # scan SSIDs: 10 max scan IEs length: 2048 bytes ........ Supported interface modes:

• IBSS
• managed
• AP
• P2P-client
