The sleek new future seems to be reaching a wireless state, with Bluetooth devices cropping up everywhere providing need ranging from helping you use your collection of credit cards to a “LoJack” for your luggage. In contrast to these complex designs, the simpler tools provide the most possibilities. Take the SoundsCape for example. This BeagleBone Cape developed by Simple Media Networks provides a Bluetooth and audio I/O interface that will allow users to connect audio devices wirelessly.
The SoundsCape uses an ADAU1361 audio codec that includes that standard Stereo Line Input, Stereo Line Output, and Stereo Headphone Output with Mono Mic In. The codec supplies >98db Signal-to-Noise Ratio for both the inputs and outputs with the outputs supported by 3.5mm stereo jack. There is also compatibility with the LCD display interface. Unfortunately, you would have to choose between this interface and the Bluetooth interface due to General-Purpose I/O limitations on the BeagleBone.
As for the Bluetooth, the SoundsCape provides a Blue tooth 4.0 interface using the PAN1323 module from Panasonic. With it, users will be able to develop streaming by Advanced Audio Distribution Profile, Headset via Hands-Free Profile, and controls with Bluetooth Low Energy.
