Mobile phone to appliance communication via audio sampling

摘要

The present subject matter relates to systems and methodologies for communicating between an appliance and a mobile device using audio signaling. An appliance is provided with an audio generating device controlled by a processor to cause the audio device to produce encoded sounds. The sounds may correspond to a series of tones. The tones are sampled using the microphone in a smartphone or other mobile computing device and decoded by an application running on the smartphone or device to provide information and/or instructions to the appliance user.
