I have 2 devices A and B. After installing Android open source WifiDirectDemo application in both the devices, if I don't go to discover page or open application in device A, I cannot discover/list device A in device B.
Is it possible to discover and connect to a device in idle state? I mean, without adding local service or without starting discovery process in device A. Basically without launching WiFiDirectDemo application at all in device A.
As far as I know, the answer is No. Basically you can only see active WiFi Direct Peers with peer discovery, i.e. the peer must be either connected, or doing peer discovery in order to be visible to the other devices discovery.
