Full log is attached to the first message.

Ok, will try that later.

Yepp, only the p2p_device=1 is needed, indeed.

ok, that's what I thought, thanks.
"iw list" is appended below. I'm not sure whether the suffix for phy?
and wlan? are the same. At least the device in question is "wlan0",
but I attached both, phy0 and phy1.
Thanks!
