A wireless device that discovers other wireless devices for the formation of a peer-to-peer connection may perform a scan that is limited in duration and power consumption. The scan nonetheless is highly likely to discover a device, if a discoverable device exists. In addition, the scan may be performed in compliance with parameters of a peer-to-protocol such that the scan may be readily implemented in a wireless device, in some embodiments even as a firmware upgrade on a wireless network interface card. Parameters of the scan may be adjusted to increase the likelihood that, if the scan completes without discovering a device, no discoverable device exists. The scan may be used in an overall process in which discovery ends or the scan is selectively repeated following an unsuccessful scan, without entering a find phase.

Peer-to-peer discovery

A wireless device that automatically forms a connection to a remote device in accordance with a peer-to-peer protocol. The remote device may be designated as an auto-connect device for the wireless device such that, when the wireless device determines that it is in the vicinity of the auto-connect device, it can re-form a connection to the remote device based on stored information for re-establishing connections among a persistent group of devices, but without any express user input. When a user requests that the wireless device perform a function that involves interaction with an auto-connect device, that function may be performed with the delay associated with forming a connection. Any of multiple techniques may be employed for identifying devices designated as auto-connect devices and for determining when the wireless device and a remote, auto-connect devices are in close proximity.
