hostp2pd

The Wi-Fi Direct Session Manager

hostp2pd implements a soft host Access Point (AP) software in Wi-Fi Direct mode, enabling a wireless network interface card to act as Ad hoc access point and Wi-Fi Protected Setup (WPS) authentication server. It features basic functionalities roughly similar to hostapd (with its hostapd.conf configuration file), which is the common AP software integrated with wpa_supplicant, generally used for infrastructure mode networking. When implementing a P2P persistent group, wpa_supplicant offers the P2P-GO features enabled by hostp2pd to connect P2P Clients like Android smartphones, as well as provide the standard infrastructure AP mode to the same P2P-GO group, without the need of hostapd.

In order to accept Wi-Fi Direct connections from P2P Clients, to activate a local P2P-GO (Wi-Fi Direct Group Owner) and to perform WPS authentication, hostp2pd fully relies on wpa_supplicant, interfacing it through the wpa_cli command-line interface (CLI): wpa_cli is run in background and p2p commands are piped via pseudo-tty communication, while events returned by wpa_cli are read and processed.

hostp2pd includes a command-line interface mode for monitoring and controlling; it can be executed as a batch or as a daemon and provides an API for integration into other Python programs.
