## Abstract

A networkable device is coupled to a wireless IP gateway or paired to a personal area network (PAN) via the use of a sonic tone, which may be a human audible tone, which encodes a symbol sequence representing a binary message useful for implementing connection to a wireless IP gateway or pairing with a PAN. In one embodiment the sonic tone conveys a media access controller (MAC) address, to facilitate connection and/or pairing. Alternatively, or in addition, the sonic tone may encode a Service Set Identifier (SSID) and password for connection to a wireless network (Wi-Fi), or a BLUETOOTH (IEEE 802.15.1) identifier and/or PIN for connection to a BLUETOOTH (IEEE 802.15.1) PAN. In particular implementation of this embodiment the tone is produced by the IP gateway and used to initiate Wi-Fi connection, and/or the tone is produced by the master device of a PAN to initiate BLUETOOTH (IEEE 802.15.1) connection.
