wpa_supplicant/WiFi Direct: wpa_cli command p2p_find returns FAIL

I'm trying to get WiFi Direct running on my Arch linux machine to connect to an Android Smartphone. But when trying to find WiFi Direct peers, the message FAIL is returned with no other error message. How can I find out what's the problem? Following the [P2P README of wpa_supplicant](http://svn.dd-wrt.com/browser/src/router/hostapd-wps/wpa_supplicant/README-P2P?rev=16495) and [this blog post](https://thangamaniarun.wordpress.com/2013/03/03/how-to-use-wi-fi-direct-on-androidubuntu-part1/) , I compiled wpa_supplicant from git (repo git://w1.fi/srv/git/hostap.git, commit 2d18ab40826ecaec26bfd82d42dcb08f2715e362, master as of May 31th, 2017, build config see below). I started wpa_supplicant and used wpa_cli to issue the command p2p_find, however, this returns the message FAIL, with no other information neither in the wpa_cli output, nor in the wpa_supplicant output or the syslog (journalctl -f) How can I get wpa_supplicant to show a helpful error message? --------------------------------- Building and running wpa_supplicant ======================= git clone git://w1.fi/srv/git/hostap.git cd hostapd/wpa_supplicant cp defconf .config # Edit .config to uncomment: # * CONFIG_AP=y # * CONFIG_P2P=y # * CONFIG_wps=y # * (CONFIG_DRIVER_NL80211=y) enabled by default # * (CONFIG_CTRL_IFACE=y) enabled by default # # * CONFIG_LIBNL32=y (Arch Linux uses libnl 3.2) # make # Run wpa_supplicant.
