Claim Text:
1. A method of communication, comprising: obtaining a message for communication using visible light communication (VLC) through a light emitting diode (LED) luminary device; formatting the message using a synchronization signal followed by one or more data signals, wherein the one or more data signals are modulated using a Frequency Shift Keying (FSK) modulation scheme; receiving a first dimming level value associated with a first brightness of light to be emitted from the LED luminary device for the communication using VLC and a second dimming level value associated with a second brightness of light to be emitted from the LED luminary device for the communication using VLC; generating a first waveform with frequencies based on the formatted message and a first duty cycle for the LED luminary device based on the first dimming level value; sending the generated first waveform to the LED luminary device for the communication using VLC; generating a second waveform with frequencies based on the formatted message and a second duty cycle for the LED luminary device based on the second dimming level value; and sending the generated second waveform to the LED luminary device for the communication using VLC.
