Abstract
An embodiment takes the form of a method carried out by a communication device. A binary data sequence is obtained at a communication device for transmission via a Bluetooth data link configured according to an audio-codec-based Bluetooth profile, wherein an audio codec is configured to receive a multi-bit data byte and output a single bit indicating whether the received multi-bit data byte is larger or smaller than a prior output reference byte, a multi-bit data byte sequence is generated based on the binary data sequence, the multi-bit data byte sequence is provided to the audio codec to induce the codec to generate a one-bit per-sample binary sequence representative of the binary data sequence, and, the generated one-bit per-sample binary sequence is transmitted via the Bluetooth data link.
