WiFi Direct Connection Using Machine-Readable Labels

摘要

Systems and methods are disclosed for a first WiFi Direct device to receive a machine-readable label from a second WiFi Direct device to provide information on the P2P WiFi capability of the second WiFi Direct device to aid the two devices in establishing a WiFi Direct connection. The machine-readable label may include the display of a QR code by the second WiFi Direct device to the first WiFi Direct device. The information on the WiFi capability of the second WiFi Direct device may include the identity of the listen channel, the operating channel, whether the device is a P2P group owner or not (e.g., a P2P client device), and other service and/or configuration information. Because the first WiFi Direct device knows whether the second WiFi Direct device is a group owner or not, the first WiFi Direct device may take the appropriate connection to establish the WiFi Direct connection.

主权项

1. A method for establishing a WiFi Direct connection between a first device and a second device, comprising:
reading by the first device a machine-readable label from the second device, wherein the machine-readable label provides information on a WiFi Direct capability of the second device; negotiating by the first device a group owner (GO)/client device relationship with the second device if the information on the WiFi Direct capability of the second device indicates that the second device is not a GO; establishing by the first device a client device relationship with the second device if the information on the WiFi Direct capability of the second device indicates that the second device is a GO; and connecting the first device to the second device in a WiFi Direct connection.
