p2p_group_add failed to initialize group interface
Sun Nov 18 18:08:20 PST 2012
I'm running the latest wpa_supplicant. My wireless adapter uses ar9170
chipset. I installed the carl9170 driver. When I tried the p2p_gorup_add,
the wpa_cli returned this:
<5>P2P: Failed to initialize group interface
Here is what the log says:
wlan0: Control interface command 'P2P_GROUP_ADD'

What's the possible reason that prevents the setup of the interface
p2p-wlan0-0? I turned off the network-manager when I run wpa_supplicant to
prevent any interference. Thank you!
