I am assuming this is because the module in the guide will be used as a receiver of audio (that is then transferred to the speakers through the wires). But what I want is the microcontroller to be the sender of audio (and the Beoplay S3 speakers to just play whatever is sent from the RN-52 module via Bluetooth).
