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. Due to the demand for hands-free phone functionality driven by laws, most modern phones will have a built-in Bluetooth functionality. 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.
Anything called Bluetooth has to be approved by the Bluetooth SIG. Refer to www.bluetooth.org on approval requirements.
