1. A process for sending headset control information from a mobile device to a wireless headset utilizing the BLUETOOTH Hands-Free Profile audio channel;
- comprising;
encoding the headset control information as an analog signal by designating a sinusoidal wave at a first predetermined frequency based upon the gain to be incremented; and
designating a sinusoidal wave at a second predetermined frequency based upon the gain to be decremented;
the first predetermined frequency being different from the second predetermined frequency, wherein the headset control information comprises audio gain input information;
digitizing the analog signal;
transmitting the digitized signal from the mobile device;
receiving the digitized signal on the wireless headset;
decoding the digitized signal into the headset control information; and
adjusting the gain of the headset based upon the decoded digitized signal.
