I have three questions:

1) Is there no support for bluetooth on android, am I correct? I have connected connected two phones through bluetooth and the interface does not appears and no neighbours detected.

2) The p2p0 interface is the WiFi Direct interface, right? 

3) Is there any way to discover other peers without interaction?

By interaction I mean get both of them to connect manually to the same wifi network.

E.g. Bluetooth discovery and connection (I know, its battery consuming)

Cheers!

Abraham.
