Bluetooth wireless technology is a wireless, short-range protocol used to interconnect devices. It can offer services that range from audio transfer to networking to a higher-level object transfer. These services make Bluetooth an ideal protocol to interface the BeagleBone to a mobile device.

While the BeagleBone can utilize almost all aspects of the Bluetooth wireless technology, we will focus on a few common uses of it in the context of the mobile connectivity for the BeagleBone.
